Standard

Provides the normal level of regenerative braking, allowing CybertruckModel SModel XModel 3Model Y to
maintain traction on loose, low-traction surfaces (such as sand, dirt, and gravel).

* Stability control intervention modifies motor torque and selectively applies the brakes to each wheel to make Cybertruck more stable and
help the driver maintain control of the vehicle. In this setting, stability control is reduced compared to on-road driving.

Wade Mode
Wade Mode allows CybertruckModel SModel XModel 3Model Y to enter and drive through bodies of water, such as rivers or
creeks.
CAUTION: It is your responsibility to gauge the depth of any body of water before entering. Damage or water ingress to
CybertruckModel SModel XModel 3Model Y as a result of driving in water is not covered by the warranty.
CAUTION: Always inspect underwater conditions (such as debris, etc.) before entering and use your best judgment.
Take care to drive slowly and safely. If the water is too deep, return to more shallow water or dry land.

1. The maximum wade depth is approximately 32 in. (815 mm) measuring from the bottom of the tire.
Wade Mode must be used any time you are driving CybertruckModel SModel XModel 3Model Y through a shallow body of
water, such as a river. To enable Wade Mode:
1. Ensure all doors and windows are fully closed, and your vehicle speed is less than 20 mph (32 km/h).
2. Access the Off-Road App.
3. Select Wade.

Owner's Manual

Off-Roading
When enabled, the Wade Mode icon appears on the touchscreen and starts a countdown for how long Wade
Mode is active. Wade Mode duration is limited to 30 minutes.

Wade Mode defaults the vehicle’s ride height to Very High and protects CybertruckModel SModel XModel 3Model Y for up to
approximately 32 in (815 mm) of water, driving at slow speeds (1-3 mph (2-5 km/h)). As water depth changes, reduce your
vehicle speed accordingly. Do not disable Wade Mode until your vehicle is fully out of water.
In addition, the vehicle’s high voltage Battery automatically pressurizes to protect the Battery from water and debris.
Muddy waters can reduce the cooling system effectiveness by adhering to the radiator. See Cleaning Mud on page 776 for
information on how to clean your vehicle after a muddy excursion. Wash your vehicle immediately after wading to reduce
chances of bacteria buildup and mud hardening after drying. Vehicles driving in waters should be regularly inspected for signs
of water ingress or damage to components including (but not limited to) the brakes, horn, lights, etc.
CAUTION: On soft or muddy underwater surfaces, CybertruckModel SModel XModel 3Model Y may sink in, effectively
increasing the water level on the vehicle. Take this possibility into account and prepare accordingly.
WARNING: Never stop or place the vehicle in Park when crossing water. Do not drive in water next to, or immediately
after, another vehicle. Currents created by other vehicles can lead to damage.
WARNING: Do not drive in deep, fast-flowing bodies of water (such as strong currents or rapids). Doing so can result in
damage, serious injury, or death.

Trail Assist
Trail Assist is available when CybertruckModel SModel XModel 3Model Y is in Overland. It maintains the speed
of the vehicle to provide greater control during steep ascents and descents.

To enable, touch Controls > Dynamics > Off-Road > Trail Assist. Then you can quickly activate or deactivate Trail Assist when
needed by single-clicking the right scroll wheel button. You can set the Trail Assist speed between 1 mph (2 km/h) and 25 mph
(40 km/h). When active, you can change the set speed by swiping on the right scroll wheel. Small swipes increase the speed in
smaller increments, whereas large swipes increase the speed in larger increments.
You can also press the accelerator or brake pedal to temporarily increase or decrease your speed. Once you remove your foot
from the pedal, the vehicle returns to your set speed. If you simultaneously brake to a lower speed and swipe down on the
right scroll wheel, or accelerate and swipe up, the set speed will automatically snap to the current speed.
NOTE: Unlike other features that allow you to set a cruising speed (such as Traffic-Aware Cruise Control), pressing the brake
pedal does not disable Trail Assist. However, pressing and holding the brake pedal firmly while at a standstill disables Trail
Assist.
NOTE: Trail Assist disengages and returns to your normal driving settings if you accelerate above 30 mph (48 km/h). It reactivates when you drive below 30 mph (48 km/h).
CAUTION: Trail Assist does not detect objects in front of the vehicle. It is your responsibility to always monitor your
vehicle's surroundings and be prepared to brake or steer for unanticipated circumstances.

Locking Differentials
CAUTION: Do not use off-road locking differentials while driving on high-traction surfaces, such as asphalt. Using
locking differentials in inappropriate situations can cause significant damage to the vehicle. Damage to the vehicle due
to improper use of locking differentials is not covered by the warranty.

Owner's Manual

1251

Off-Roading
Open Differentials
Most passenger vehicles are equipped with open differentials on the drive axles. When a vehicle with open differentials turns
on a corner or paved road, the wheels on the outside of the curve rotate more quickly than the wheels on the inside of the
curve to prevent wheel hop and reduce vehicle instability. However, in low-traction scenarios (such as off-roading or driving in
snow), additional torque can get directed towards the wheel(s) with less traction, which may lead to the vehicle getting stuck.

Locking Differentials
CybertruckModel SModel XModel 3Model Y is equipped with locking differentials for increased traction during certain low
traction and off-road conditions.
Locking differentials lock both wheels of an axle together, which forces the wheels to rotate at the same speed. This
distributes the torque across the same axle based on the available traction in each wheel. When one of the locked wheels has
significantly reduced traction (on sand, ice, etc.) more torque is applied to the wheel with greater traction. This distribution of
torque helps the vehicle continue moving in low traction environments.
Dual Motor Variants: are equipped with mechanical front and rear locking differentials.
Tri-Motor (Cyberbeast) Variants: are equipped with a mechanical front locking differential, and a virtual rear locking differential
to provide sufficient torque in each rear wheel. The rear locking differential automatically engages in certain drive modes and
speeds, and cannot be manually engaged or disengaged.
CAUTION: Loading CybertruckModel SModel XModel 3Model Y to the Gross Vehicle Weight Rating (GVWR) and
engaging the locking differentials may result in damage to the drivetrain (see Vehicle Loading on page 1429).
WARNING: Do not expect the locking differentials to provide sufficient traction if the vehicle does not have appropriate
tires for the conditions, or CybertruckModel SModel XModel 3Model Y is in a situation where all four wheels are
spinning.

Engaging Locking Differentials On Road
WARNING: Your vehicle's turning radius increases when locking differentials are engaged. It is your responsibility to be
aware of your surroundings and drive carefully.
Engaging locking differentials while driving on roads is intended for specific situations where you temporarily need extra grip
on loose or uneven terrain, such as getting un-stuck from a snow bank. Do not engage locking differentials unless it is needed
for the road conditions. Navigate to Controls > Dynamics > Engage Rear Locking Differential. When enabled, Slippery Surface
also enables (see Slippery Surfaces on page 1237). Engage Rear Locking Differential should not be used for regular driving on
slick surfaces.
When you engage locking differentials while driving on roads, your speed is limited to 35 mph (56 km/h). The stability control
icon may appear momentarily while the locking differentials disengage (see Vehicle Status on page 1117).
NOTE: This option is not available on Tri-Motor (Cyberbeast) vehicles.

Engaging Locking Differentials Off Road
Before you engage locking differentials, consider your driving situation (such as the terrain, weather, etc.). The rear locking
differentials are ideal for off-roading uphill or on level surfaces. Front locking differentials are typically used when you need
more traction at the front of the vehicle, like rock crawling. To engage:
1. Access the Off-Road app.
2. Select the locking differentials you want to enable.
For dual motor variants:
◦ All On
◦ Rear Only
◦ Off
For Tri-Motor (Cyberbeast) variants:

Orange question mark (?): Unknown locker position.

Red exclamation point (!): System fault or locking differential unavailable (see Troubleshooting on page 1253).

You may need to drive a short distance to engage once enabled.
Once the locking differentials are fully engaged, the vehicle may slightly rock side to side when turning at low speeds. This is
normal behavior when the touchscreen indicates a fully engaged locker (solid orange icon).
The locking differentials may cancel or delay engaging in various cases. If the locking differentials are unable to engage, a
chime sounds and a message displays on the touchscreen. See Troubleshooting on page 1253 for more information.
WARNING: Driving with locked differentials may reduce vehicle responsiveness to steering. Always monitor your
vehicle's behavior and the surroundings. Failure to do so may result in damage or serious injury.

Disengaging Locking Differentials
To disengage, touch the differential icon on the touchscreen and select Off. You may need to drive a short distance to
disengage. The locking differentials also automatically attempt to disengage whenever the vehicle shifts out of Drive, or when
a different drive mode is selected.
When you disengage the locking differentials, the icon may blink orange before disappearing from the touchscreen. Ensure
the locking differentials are disengaged before you drive on paved roads or at speeds higher than 35 mph (56 km/h). Check
the vehicle wheels are not skipping when turning.

Troubleshooting
Off-Road Troubleshooting
You may need to increase traction while off-roading (such as for getting unstuck or overcoming an obstacle). Follow these
general guidelines to provide more traction to CybertruckModel SModel XModel 3Model Y:
1. Engage Overland (see Overland on page 1248 for more information).
2. Adjust the suspension height. Raise the suspension until the vehicle is no longer obstructed. Avoid lowering the
suspension to prevent damage (see Suspension on page 1238).
3. Customize Terrain based on the current surface conditions. For high traction terrains, select Rock. For looser terrains,
select Sand.
4. Engage the front and/or rear locking differentials (see Locking Differentials on page 1251).
5. For softer terrain or steep inclines, engage Trail Assist for a steady progression through complex terrain (see Trail Assist on
page 1251).
If you still need more traction, perform the following:
1. Decrease tire pressure to 36 PSI. This increases tire contact with the surface, which can help provide more traction.
CAUTION: The TPMS warning thresholds may be lowered to accommodate different off-road needs. Do not rely
solely on the TPMS warning indicator when in an Off-Road mode or setting, as these thresholds do not comply with
Federal TPMS standards. It is your responsibility to ensure tires are adequately inflated at all times and are inflated
back to normal levels before regular driving on roads.
2. Use traction aids, such as traction boards.
3. Tow your vehicle. See Instructions for Transporters on page 1439 for more information on towing
CybertruckModel SModel XModel 3Model Y.

Limitations and Warnings
Off-road driving depends on the performance of the air suspension system, brakes, power steering, and other vehicle
systems. If there is a condition affecting the performance of any dependent system, a message displays on the touchscreen
and off-road driving modes are unavailable.
WARNING: Before driving off road, carefully survey the terrain and be aware of the weather forecast and other
environmental conditions. Exercise extreme caution when approaching steep ascents and descents. While driving off
road, always be aware of your surroundings and survey the terrain as necessary. Tesla is not liable for any damage to
CybertruckModel SModel XModel 3Model Y resulting from off-road driving.

WARNING: Never depend on the driving visualization to show you obstacles in front of, behind, or to the sides of
CybertruckModel SModel XModel 3Model Y. Always use caution while driving off road and perform visual checks when
necessary. The visualization relies on the cameras mounted on CybertruckModel SModel XModel 3Model Y (see
Cameras on page 1134). External factors (such as a dirty or obscured lens) may affect the performance of a camera, and
the cameras may not detect objects or barriers that can potentially cause damage or injury.
WARNING: Visibility may be limited by sharp crests and uneven terrain. Always check what is at the top of a hill and over
the crest before driving over it, and be aware of steep descents or other obstacles.
WARNING: Before approaching an obstacle, ensure that CybertruckModel SModel XModel 3Model Y has enough
ground clearance to clear it. If the bottom of CybertruckModel SModel XModel 3Model Y is contacting the ground even
with the ride height at the highest setting, reduce your speed or avoid the obstacle altogether.
WARNING: Exercise extra caution when the terrain surface is wet, sandy, or slippery. Loose gravel, sand, and other
environmental conditions may affect the performance of Off-Road Modes.
WARNING: Before driving off road, make sure that loose items in the cabin are stowed or secured and ensure that the
cargo bed is free of cargo, or that cargo is tightly secured.

Towing
Towing a Trailer
NOTE: You cannot enable Off-Road Modes and Trailer Mode at the same time.
NOTE: If the towing capacity on the hitch label conflicts with the information provided in this owner's manual, this owner's
manual takes precedence.

Towing Guidelines
Towing a trailer puts additional load on the motors, drive train, brakes, tires, and suspension and significantly decreases range.
If you tow a trailer, follow these general guidelines:
• Reduce your driving speed and avoid sudden maneuvers. Keep in mind that when towing a trailer, steering, stability, turning
radius, stopping distances, and braking performance are different when compared to driving without a trailer.
• Increase your following distance by maintaining at least twice the typical distance from the vehicle ahead. This helps avoid
situations that require heavy braking. Sudden braking may result in skidding or jack-knifing, and loss of control.
• Avoid sharp turns. Sharp turns can cause the trailer to contact CybertruckModel SModel XModel 3Model Y and cause
damage. Make wider turns to prevent the trailer from hitting curbs, road signs, trees, or other objects.
• Periodically check the trailer lights and turn signals to confirm that bulbs are still working (see Trailer Light Test on page
1259). When towing a trailer, the turn signal arrows on the touchscreen flash as normal, even if the bulbs on the trailer are
burnt out.
• Periodically confirm the cargo is secure.
• Periodically confirm the trailer brakes are working (see Trailer Brakes on page 1258).
• Avoid parking on a grade (see Parking with a Trailer on page 1261).
• Regularly confirm that all towing components are secured.

Before Towing a Trailer
Before towing a trailer, you must do the following:
1. Review all regulations and legal requirements in your state/region that apply to towing a trailer. Failure to comply with
regulations can compromise your safety.
2. Inflate tires to the cold tire inflation pressure specified in Tire Pressures when Towing on page 1257.
3. Set the suspension height to match the trailer height. Tesla recommends Low (Controls > Suspension > Low). You must
choose a ball mount suitable for your towing needs. See Ball Mount Specifications on page 1262 for more information.
4. Adjust all mirrors to provide a clear rearward view without a significant blind spot.
NOTE: Use towing mirrors for larger trailers.
5. Confirm the trailer load is evenly distributed such that the trailer tongue weight is approximately 10% of the total trailer
weight, without exceeding the maximum tongue weights provided in Towing Capacity on page 1257.
6. Engage Trailer Mode (see Trailer Mode on page 1258).
7. Calibrate the trailer brakes (see Trailer Brakes on page 1258).
Then, confirm the following:
1. CybertruckModel SModel XModel 3Model Y rests horizontally with the trailer attached. If the vehicle is tipped up at the
front, and down at the rear, check that you are not exceeding the maximum towing capacity and tongue weights provided in
Towing Capacity on page 1257.
2. All trailer hitch parts and attachments, safety chains, and electrical connectors are in good condition and properly
connected. If any problems are apparent, do not tow the trailer.
3. Trailer lights (brake lights, turn signal lights, marker lights, etc.) are working properly.
4. The trailer tongue is securely connected to the hitch ball.

1256

Owner's Manual

Towing
5. Safety chains are properly connected between the trailer and the vehicle. Cross the safety chains under the tongue of the
trailer to help prevent the tongue from contacting the road if it separates from the hitch. Leave enough slack in the safety
chains to allow for turns and ensure that the chains can never drag on the ground.
6. Wheel chocks are available and easy to access.
7. All cargo is secured.
NOTE: For general information about trailer safety provided by the National Highway Traffic Safety Administration, go to
https://one.nhtsa.gov/cars/problems/equipment/towing/index.htm.
WARNING: The trailer tongue weight must be approximately 10% of the total trailer weight without exceeding the
maximum tongue weights provided in Towing Capacity on page 1257. Loads that are balanced over the wheels or heavier
in the rear can cause trailer sway, resulting in loss of vehicle control.
WARNING: Always ensure that cargo is secured in the trailer and will not shift. Dynamic load shifts can cause loss of
vehicle control, resulting in serious injury or death.

Towing Capacity
The total trailer weight (including all cargo and additional equipment), and the trailer tongue weight, must never exceed the
following:
Wheel Size

Maximum Towing Capacity

Maximum Tongue Weight*

20" x 9J

11,000 lb (4,990 kg)

1,110 lb (499 kg)

*The tongue weight is the downward force that the weight of the trailer exerts on the hitch. It must not exceed 10% of the
maximum towing capacity. Carrying a significant amount of equipment, passengers, or cargo in the tow vehicle can reduce the
tongue weight it can handle, which also reduces the maximum towing capacity. Maximum towing capacity is calculated
assuming the GVWR (Gross Vehicle Weight Rating) is not exceeded. For GVWR, see Vehicle Loading on page 1429).
CAUTION: Tesla assumes no responsibility for damage or injuries resulting from towing a trailer, for any errors or
omissions in the instructions accompanying towing equipment, or for your failure to follow the proper instructions.
Damage caused by towing a trailer is not covered by the warranty.
WARNING: Do not overload the vehicle or trailer. Doing so can cause poor performance, vehicle damage and loss of
vehicle control, resulting in serious injury.
WARNING: Do not use the trailer hitch to tow/transport CybertruckModel SModel XModel 3Model Y.
WARNING: Never operate a trailer with a negative tongue weight, where the trailer tongue pulls upward on the trailer
hitch. Negative tongue weights can significantly increase the risk of trailer sway or loss of stability.

Tire Pressures when Towing
When towing a trailer, tire pressures must be adjusted to accommodate the additional load. Keep tires inflated to the pressures
shown below (these pressures override the pressures that are provided on the Tire and Loading information label – see Vehicle
Loading on page 1429):
Tires

Cold Tire Inflation Pressure

20" All Season

50 psi

20" All Terrain

65 psi

WARNING: Check tire pressures using an accurate pressure gauge when tires are cold (see Tire Pressures on page
1395). Driving one mile (1.6 km) warms the tires sufficiently to affect tire pressures. Parking the vehicle in direct sunlight
or in hot weather can also affect tire pressures. If you must check warm tires, expect increased pressures. Do not let air
out of warm tires in an attempt to match recommended cold tire pressures. A hot tire at or below the recommended cold
tire inflation pressure is dangerously under-inflated.
WARNING: Never attempt to tow a trailer when a tire is faulty or has been inflated using a tire repair kit. A temporarily
repaired tire is not designed to sustain the towing load. Towing using a faulty or temporarily repaired tire can result in
tire failure and loss of vehicle stability.

Towing
• Enable/disable Trailer Mode on page 1258.
• Customize Trailer Brake Gain on page 1259.
NOTE: Tesla recommends always enabling the trailer brakes, otherwise stopping distance may be increased. To disable the
trailer brakes, first disable Trailer Mode or set the Trailer Brake Gain to 0.
• Choose how to manually apply the trailer brakes (either with the touchscreen or right scroll button). The trailer brake
activation button is unaffected.
• Adjust Trailer Brake Boost on page 1259.
• Toggle Adaptive Regenerative Braking on page 1259.
• Perform the Trailer Light Test on page 1259.
You can also set up a shortcut for Towing & Hauling by adding it to your vehicle "Cards" area, near the bottom of the
touchscreen.
Trailer Brake Gain
The Trailer Brake Gain slider is a scale between 0 and 10 that calibrates the degree of trailer braking applied when you press
the brake pedal normally. 0 applies no trailer brakes, whereas 10 applies the full trailer brakes.
Set this up each time you connect a trailer to ensure your trailer brakes do not lock up:
1. Ensure the trailer is securely attached to the CybertruckModel SModel XModel 3Model Y hitch assembly.
2. Drive CybertruckModel SModel XModel 3Model Y in a safe, open area at low speeds (10-15mph or 15-25 km/h).
3. Use the right scroll button on the steering wheelsteering yoke (or steering wheel) or Trailer Brake Activation (set your
preference in Towing & Hauling) to apply the trailer brakes while moving. Adjust the Trailer Brake Gain as needed to ensure
the trailer brakes do not lock up when they are applied. If the wheels do lock up, decrease the amount of gain slightly and
repeat this process.
The ideal Trailer Brake Gain varies depending on your trailer load, number of axles, and surface conditions. You must adjust as
needed while conditions change.
Trailer Brake Boost
Tesla recommends initially setting your Trailer Brake Boost to Low. Once Trailer Brake Gain is calibrated, adjust based on your
preferences by driving around in a safe, open area and applying the brakes as you would in normal traffic. Increasing will make
your brakes react more quickly, although the braking feels more harsh to passengers.
Adaptive Regenerative Braking
At the start of every drive, CybertruckModel SModel XModel 3Model Y estimates the load to determine the proper level of
regenerative braking. Regenerative braking will start at the standard level and increase as the vehicle learns your trailer/cargo
weight.
NOTE: Weight estimation works best when driving in a straight line on a flat, smooth surface.
WARNING: It is your responsibility to determine when to enable Adaptive Regenerative Braking. Always drive safely and
avoid situations that could require heavy braking.
WARNING: Towing increases your stopping distance. When towing, increase your following distance and avoid
situations that could potentially cause heavy braking. Failure to do so can result in a collision.
WARNING: Observe all regulations and legal requirements in your regional and national jurisdictions that apply
specifically to trailer towing and brake requirements. Many regions require a breakaway switch, located on the tongue of
the trailer, to activate the trailer brakes if the trailer separates from the vehicle. Failure to comply with regulations can
compromise your safety.
Trailer Light Test
Before towing, and periodically during towing, use Trailer Light Test to confirm the trailer lights are working as expected.
WARNING: Do not tow a trailer if the trailer lights or trailer brakes are not working properly.

Towing
Trailer Brake Controller Limitations
WARNING: It is your responsibility to understand your towing needs, proper towing procedures, trailer brakes (such as
their use and limitations), and the risks and limitations of towing. Do not tow with CybertruckModel SModel XModel
3Model Y if you do not have towing knowledge and experience; doing so may result in damage, injury or death. Damage
as a result of improper towing is not covered by the warranty.
Keep in mind the following brake controller limitations:
• Properly maintain and use trailer brakes as intended to prevent damage.
• The trailer brake controller and auxiliary output is 12V.
• Abusive or extensively long manual activations of the trailer brake controller may cause overheating with some trailer brake
loads.
• Maximum power draw - The onboard trailer controller is designed to support most trailer power applications. The power
allocations are:
Standard trailer brakes (when braking power is derived from brake
output, e.g. non-EOH Electric Drum brakes)

Lights: Max. 220 Watts total for all light
outputs combined.
Auxiliary power (AUX 12V+ Charging): Max.
270 Watts (20 Amps).
Trailer brakes: Max. 331 Watts

Electric over Hydraulic trailer brakes (braking power is derived from
auxiliary power output, e.g. EOH, Hydraulic disk brakes, see Electric
Over Hydraulic (EOH) Brakes on page 1260)

Lights: Max. 220 Watts total for all light
outputs combined.
Auxiliary power (AUX 12V+ Charging): Max.
405 Watts (30 Amps).
Trailer brakes: Max. 48 Watts (Current draw
must be less than 3 Amps).

CybertruckModel SModel XModel 3Model Y switches to the standard brakes if a 3A or higher load on the trailer brake
connections is detected.

Electric Over Hydraulic (EOH) Brakes
CybertruckModel SModel XModel 3Model Y supports standard electric brakes and Electric over Hydraulic (EOH) brakes. If
using EOH brakes, Tesla recommends connecting a battery in parallel with the auxiliary power output to the EOH unit.
The auxiliary output is capable of supplying up to 30 Amps when supporting an EOH trailer brake unit. You are responsible for
understanding the power needs of your EOH trailer brake unit. Using an EOH trailer brake controller that draws more than 30
Amps may result in a loss of power to the trailer brakes while braking.
The usage of only an EOH unit with the auxilary power port is supported for maximum braking availability. A battery in parallel
is recommended. The battery must be in good health and is expected to already be present in most states per DOT
regulations.
CAUTION: Tesla does not recommend using EOH trailer brakes simultaneously with other auxiliary power loads. Doing
so could lead to complications or loss of power to the EOH trailer brakes unit.

Parking with a Trailer

Whenever possible, avoid parking on a grade. However, if parking on a grade is absolutely necessary, place wheel chocks
under the trailer wheels:
1. One person presses and holds the brake pedal.
2. A second person places the wheel chocks under the wheels on the downgrade side of the trailer's tires.
3. When the chocks are in place, slowly release the brake pedal and ensure the chocks hold the weight of the vehicle and
trailer.
NOTE: When testing chocks, ensure that Vehicle Hold (see Vehicle Hold on page 1235) is engaged. If Vehicle Hold is
braking CybertruckModel SModel XModel 3Model Y, the associated indicator light appears on the touchscreen. To
disengage Vehicle Hold, press and release the brake pedal.
4. Place the vehicle in Park.
WARNING: If parking on a grade is necessary, ensure that all trailer wheels have been securely chocked. Failure to do so
can result in serious damage, injury, or death.

Trailer Sway Mitigation
When trailer sway is detected, your vehicle's electronic stability control system attempts to apply the appropriate amount of
braking to minimize trailer sway. The touchscreen briefly displays the traction control system indicator. Manually applying the
brakes (via right scroll button on the steering wheelsteering yoke (or steering wheel) or the Trailer Brake setting) when the
system is actively braking to mitigate trailer sway does not cancel this automatic braking. However, it is still your responsibility
to drive carefully and brake when needed, taking into consideration possible trailer sway.
