Wall plug adapter error - Charge rate reduced
Plug adapter fully into Mobile Connector and retry
What this alert means:
Your Mobile Connector is unable to communicate with the wall plug adapter. Because your Mobile Connector cannot monitor
the wall plug adapter temperature, charge current is automatically reduced to 8A.
What to do:
1. Unplug your Mobile Connector, including the wall plug adapter, completely from the wall outlet.
2. Make sure the connection between the wall plug adapter and the main body of your Mobile Connector is secure.
a. Disconnect the wall plug adapter completely from the main body of your Mobile Connector.
b. Fully reinsert the wall plug adapter into the main body of your Mobile Connector by pushing it into the socket until it
snaps into place.
3. Try charging again by plugging the Mobile Connector, including wall plug adapter, fully into the wall outlet.
4. If the alert persists, try using a different wall plug adapter (see steps above to make sure the adapter is fully connected to
your Mobile Connector).
a. If the alert is no longer present, the issue is likely with the wall plug adapter you were using previously.
b. If the alert persists, the issue is likely with your Mobile Connector.

Mobile Connector control box temperature high
Maximum charge rate reduced
What this alert means:
Charge current has been temporarily reduced because the Mobile Connector has detected increased temperature inside its
control box housing.
What to do:
Make sure the Mobile Connector is not covered by anything, and that there is no heat source nearby. If the problem persists in
normal ambient temperatures (under 100°F or 38°C), service is required.

Charge rate reduced - Wall plug temperature high
Wall outlet and wiring inspection recommended
What this alert means:
High temperature detected by Mobile Connector alerts indicate the outlet used to charge is becoming too warm, so charging
has been slowed to protect the outlet.
This is not typically an issue with your vehicle or your Mobile Connector, but rather an issue with the outlet. A warm outlet may
be caused by a plug that is not fully inserted, a loose building wiring connection to the outlet, or an outlet that is beginning to
wear out.
What to do:
Make sure your adapter is fully plugged into the outlet. If charging speed does not return to normal, contact an electrician to
inspect the outlet and building wiring connections to the outlet and complete any repairs needed.
If the outlet is worn, it should be replaced with a high-quality outlet. Consider upgrading to a Tesla Wall Connector for greater
convenience and highest charging speed.

What to do:
Make sure the Mobile Connector is fully inserted into your vehicle's charge port inlet.

Air pressure below recommendation for tires
Check pressure and refill air as needed
What this alert means:
This alert does NOT indicate that there is a flat tire.
The tire pressure monitoring system (TPMS) has detected that the air pressure in one or more of your tires is at least 20%
lower than the recommended cold tire pressure.
See Maintaining Tire Pressures on page 742 for detailed information on where to find the recommended cold pressure (RCP)
for your vehicle's tires, how to check tire pressures, and how to keep your tires properly inflated.
This alert may appear in cold weather because the air in your tires naturally contracts when it becomes cold, decreasing tire
pressures.
What to do:
Add air to maintain the recommended cold tire pressure. Although drops in tire pressure are expected in colder weather, the
recommended cold tire pressure should be maintained at all times.
The alert may clear as the vehicle is driven. This is because the tires will warm up and the tire pressure will increase. Even if the
alert clears, the tires should still be refilled with air once they have cooled.
The alert will clear once the Tire Pressure Monitoring System detects that each of your tires is inflated to the recommended
cold pressure.
• The alert and Tire Pressure indicator light may still be present immediately after you have filled your tires to the
recommended cold pressure, but both should clear once you have driven a short distance.
• You may need to drive over 15 mph (25 km/h) for at least 10 minutes for the Tire Pressure Monitoring System to measure
and report your updated tire pressures.
If you repeatedly see this alert for the same tire, have the tire inspected for a slow leak. You can visit a local tire shop or
schedule service using your Tesla Mobile App.
For more information on tire pressure and inflation, see Tire Care and Maintenance on page 742.

What this alert means:
This alert indicates that one or more of the tires on your vehicle is extremely low or flat.
The tire pressure monitoring system (TPMS) has detected that the air pressure in one or more of your tires is significantly
lower than the recommended cold tire pressure.
What to do:
You should pull over carefully as soon as possible. In a safe location, check for a flat tire.
You can request Tesla roadside assistance options (mobile tire, loaner wheel, tow) if required. See Contacting Tesla Roadside
Assistance on page 914 for more information.
In a non-emergency situation, it is recommended that you visit a local tire shop for assistance or schedule service using your

Autosteer temporarily unavailable
What this alert means:
Autosteer is temporarily unavailable. This could be a temporary condition caused by an external factor, such as:
• Missing or faded lane markers.
• Narrow or winding roads.
• Poor visibility due to rain, snow, fog, or other weather.
• Extremely hot or cold temperatures.
• Bright light due to other vehicle headlights, direct sunlight, or other light sources.
This alert will also be present if you exceeded the maximum speed limit for Autosteer with Autosteer active. In this case,
Autosteer will not be available for the rest of your current drive.
What to do:
Continue to your destination. If Autosteer is not available by the time you reach your destination, and remains unavailable
during your next planned drive, check for the following:
• Damage or obstruction caused by mud, ice, snow, or other environmental factors
• Obstruction caused by an object mounted on the vehicle, like a bike rack
• Obstructions caused by adding paint or adhesive products like wraps, stickers, or rubber coatings to your vehicle
• A damaged or misaligned bumper

Autosteer is unavailable because your vehicle has exceeded the maximum speed limit for this driver assistance feature.
What to do:
Take immediate control of the steering wheelsteering yoke (or steering wheel) and maintain control until you reach your
destination.
In most cases, Autosteer will not be available for the rest of your current drive. To reset it, bring the vehicle to a complete stop
and shift into Park. When you shift into Drive to travel to your next destination, Autosteer should be available again.
NOTE: If this alert becomes active while you are driving in Germany, Autosteer should be available again once your vehicle is
traveling below the Autosteer speed limit.
If Autosteer is not available during your next drive, and remains unavailable throughout subsequent drives, schedule service at

Cruise control unavailable
Reduced front camera visibility
What this alert means:
Traffic-Aware Cruise Control and Autosteer are unavailable because one or more of the front cameras in your vehicle is
blocked or blinded by external conditions.
Traffic-Aware Cruise Control and Autosteer will remain unavailable while a front camera lacks adequate visibility. Cameras may
have limited or no visibility due to:
• Dirt or debris on the camera surface.
• Environmental conditions like rain, fog, snow, or dew.
• Bright sunlight or glare from another light source.
• Low or limited light conditions, including unlit or poorly lit roadways at night.
• Condensation (water droplets or mist) on the camera surface.
• Monotonous environmental features, including tunnel walls or highway dividers.
What to do:
Continue to your destination. Your vehicle is OK to drive.
This is often a temporary issue that clears up on its own. If the alert does not clear by the end of your drive:
• Inspect and clean the front camera area at the top center of the windshield before your next planned drive.
• Check the camera surface for condensation, dirt, or other debris and attempt to clear any obstruction.
See Cleaning a Camera on page 766Cleaning a Camera on page 765Cleaning a Camera on page 766Cleaning a Camera on

Although condensation on the inside of the front camera enclosure cannot be wiped clean, you can usually clear it quicker by
following these steps:
1. Pre-condition the cabin with the temperature set to High and A/C turned ON.
2. Turn on the front windshield defroster.

more cameras can become uncalibrated.
