If you have checked for and cleared any debris or foreign objects, but charging is still limited or your vehicle will not charge at
all, the charge port latch may be frozen. Press the Defrost Car button in your Tesla Mobile App to defrost your vehicle for
approximately 30 - 45 minutes. This should help thaw any ice on the charge port latch so the charge cable can be properly
inserted.
NOTE: Be sure to use Defrost Car in your Mobile App to defrost your vehicle. Adjusting the climate control settings in your
vehicle's touchscreen will not be as effective.
As this alert usually indicates a temporary condition due to cold ambient temperature or a charge port inlet obstruction, and it
does not typically indicate an issue with your vehicle that can be resolved by scheduling service, it is recommended that you:
• Make sure the charge cable is fully inserted during charging.
• Make sure any charge port inlet obstruction has been removed.
• Press the Defrost Car button in your Tesla Mobile App to defrost your vehicle for approximately 30 - 45 minutes before
trying to charge again.
If the alert remains present, limited AC charging should still be available.

Charge rate reduced - Wall connection hot
Outlet or Wall Connector wiring must be checked
High temperature detected by Wall Connector alerts indicate the building connection to the Wall Connector is getting too
warm, so charging has been slowed to protect the wiring and Wall Connector.
This is not typically an issue with your vehicle or your Wall Connector, but rather an issue with the building wiring. This may be
caused by a loose building wiring connection to the Wall Connector and can be fixed quickly by an electrician.
To regain normal charge speed, contact an electrician to inspect the building wiring connection to the Wall Connector. They
should make sure that all wires are properly connected and torqued according to the installation guide for the Wall Connector.

Charging adapter has electric arc flash hazard
Use different charging equipment
Charging is unavailable because your vehicle has detected an electric arc flash hazard in the third-party charging adapter used
to connect a Combined Charging System (CCS) charge handle to your vehicle’s charge port.
An electric arc flash can occur if you attempt to unplug while actively charging with the third-party charging adapter, and an
electric arc flash can cause serious bodily injury and/or property damage.
Follow the steps below to mitigate this risk:
1. Make sure charging is completely stopped.
a. Use your vehicle touchscreen to confirm charging has stopped, or to stop charging if necessary.
b. Use the charging station display and controls to confirm charging has stopped, or to end any active charging session.
2. Make sure no flashing green or blue light (LED) is visible on your vehicle’s charge port.
3. Unplug the charging adapter from your vehicle’s charge port.
4. Confirm again that the charging station indicates no active charging session.
5. Unplug the charging adapter from the charge handle.
Use different charging equipment to charge your vehicle.

Regenerative braking temporarily reduced
Regen will increase as vehicle is driven
Regenerative braking performance has been temporarily reduced to below 65% of its full capacity. The exact reduction is
indicated by the dashed lines on the power meter.
While this alert is present, the deceleration rate of the vehicle due to regenerative braking will be reduced and more brake
pedal application will be required to slow the vehicle (similar to what is needed in a gas-powered, non-electric, vehicle).
This alert is expected under the following conditions:
• Battery is near full charge:
◦ Regenerative braking is reduced when the battery is at 95% charge or higher.
• Battery is cold:
◦ The battery may not be warm enough for full regenerative braking performance (possibly at the beginning of a drive).
◦ In extremely cold climates, this alert may remain present indefinitely and regenerative braking may remain reduced, as
driving the vehicle may not warm the battery enough to fully restore performance.
Typically, driving will clear this alert because it will reduce the battery charge level below 95% and sufficiently warm the
battery.
This is a completely normal part of vehicle operation and should not cause alarm. The notice on the screen is for your
information only.

Assist for low brake performance activated
To stop, keep brake pedal firmly pressed
Hydraulic Fade Compensation is active. This brake assist function activates temporarily to make sure you have full braking
capability in conditions where reduced braking performance is detected by your vehicle.
Continue to press the brake pedal as you normally would, and do not "pump" (repeatedly press and release) the pedal as this
will interrupt the function.
This alert will clear when your vehicle comes to a stop or you are no longer pressing the brake pedal. It may still be displayed
for up to 5 seconds afterward.
When this assist function activates, you may feel the brake pedal pull away from your foot and notice a strong increase in brake
pressure. You may also hear a pumping sound coming from the brake hydraulic unit at the front of the vehicle. This will usually
last for a few seconds, depending on road surface and vehicle speed. This is completely normal and does not indicate any
issue with your vehicle.
Reduced braking performance is usually temporary, and can occur for a number of reasons including high brake temperatures
after heavy brake use, or driving in extremely cold or wet conditions. It can also indicate that your brake pads or rotors have
worn to the point that normal replacement is needed.
If you continue to experience reduced braking performance which does not improve over time, please contact Tesla service at
your convenience for a brake inspection.
For more information, see Hydraulic Fade Compensation on page 232.

Cannot charge - Poor grid power quality possible
Retry / Try other charge location or Supercharging
Charging has stopped due to a condition that prevents your vehicle from charging with AC power. DC fast charging /
Supercharging should still function as expected.
This condition could occur due to power supply disturbances caused by the external charging equipment or by the electrical
power grid. In some cases, this condition can even result from turning on nearby electric devices that draw a lot of power.
If these possible causes can be ruled out, then a condition with your vehicle itself may also be affecting AC charging.
This alert is often accompanied by other alerts that can help you identify and troubleshoot the condition. Start by investigating
any other displayed alerts that relate to charging.
Further troubleshooting tips based on equipment type:
• If using a Mobile Connector, try charging your vehicle with a different wall outlet.
◦ If your vehicle starts to charge and continues to charge as expected, the issue was likely with the original wall outlet. It
is recommended that you contact an electrician to inspect the building wiring connection to that outlet.
◦ If your vehicle still does not start to charge, or does not continue to charge as expected, the issue may be with the

Unable to charge - Mobile Connector GFCI tripped
Unplug charge handle from charge port and retry
The vehicle cannot charge because the ground-fault circuit interrupter (GFCI) in the Mobile Connector has tripped.
Like the GFCI in a wall outlet, this feature is designed to stop the flow of electricity when there is a problem. It has interrupted
charging to protect your vehicle and the charging equipment.
This could happen for many reasons. The problem could be in the charge cable, the charge handle, the charge port, or even an
onboard vehicle component.
Inspect the charge port as well as the charge handle for pooled water or unusual levels of moisture.
• If you find excessive moisture, wait and let both the inside area of the charge port and the exposed portion of the charge
handle dry sufficiently before trying again.
Inspect the charge equipment for damage.
• If the cable is in any way damaged or deteriorated, do not use it. Try different charging equipment instead.
• If the cable is in good condition, try charging again with the same Mobile Connector.
If the issue persists and prevents charging, try charging with different charging equipment.
• Try charging with multiple, different types of charging equipment.
