APP_w224  
Cruise control unavailable  
Continue driving to allow cameras to calibrate  
What this alert means:  
Traffic-Aware Cruise Control and Autosteer are unavailable because the cameras on your vehicle are not fully  
calibrated.  
Your vehicle must maneuver with great precision when features like Traffic-Aware Cruise Control and Autosteer are  
active. Before these features can be used for the first time, the cameras must complete an initial self-calibration.  
Occasionally, one or more cameras can become uncalibrated.  
What to do:  
Continue to your destination. Your vehicle is OK to drive.  
Traffic-Aware Cruise Control and Autosteer will remain unavailable until camera calibration is complete.  
When calibration is complete, Traffic-Aware Cruise Control and Autosteer should be available.  
For your convenience, a calibration progress indicator is displayed on the touchscreen. Calibration typically  
completes after your vehicle has driven 20-25 miles (32-40 km), but the distance varies depending on road and  
environmental conditions. For example, driving on a straight road with highly visible lane markings helps the  
cameras calibrate quicker.  
If the alert persists and camera calibration has not completed after your vehicle has driven 100 miles (160 km) or  
more, or Traffic-Aware Cruise Control and Autosteer remain unavailable despite successful camera calibration,  
schedule service at your earliest convenience. Your vehicle is OK to drive in the meantime.

Rear tire tread depth low - Schedule service  
Inspect tires for rotation/replacement  
What this alert means:  
NOTE: This alert does NOT indicate that there is a flat tire.  
Your vehicle has detected that the rear tires have experienced more wear over time than the front tires, exceeding  
the recommended difference.  
What to do:  
It is recommended that the tread depth on all tires be inspected. As your tires wear during normal driving, the rear  
tires generally wear more quickly than the front tires.  
Tire rotation is important to balance tire wear evenly across all tires.When staggered tires (different front and rear  
tire sizes) are installed, regularly rotating the front and rear tires between the left and right sides of your vehicle will  
still make your tires wear more evenly and extend their life.  
Failure to rotate tires as recommended poses a risk of hydroplaning and losing control of the vehicle on wet roads.  
Failure to rotate tires also decreases the life of your tires, requiring premature replacement.  
It is recommended that you schedule service via your Tesla Mobile App or with an independent service provider to  
have your tires rotated when:  
• The difference in tire tread depth between any front and rear tire exceeds 1.5mm  
Your vehicle has been driven for more than 6,250 miles (10,000 km) since the last rotation  
Tires may need to be replaced if the rear tread depth is determined to be at an unsafe level and either of these  
conditions applies:  
• A tire rotation is no longer adequate  
• Staggered tires (different front and rear tire sizes) installed on your vehicle make front/rear tire rotation  
unavailable  
Upon completion of tire inspection and any necessary tire service, update your vehicle’s tire configuration to  
optimize your vehicle settings to your tires and clear the alert for at least 6,250 miles. For more information, see Tire  
Care and Maintenance on page 184.  
It is not recommended that you rely on this alert instead of routine checks of tire tread depth. This alert should only  
be present when your vehicle estimates the tires are far beyond the recommended service interval.  
This alert is calibrated for Tesla tires and is not expected to work with tires of different types or sizes, including  
combinations of different tire brands or models. It may not display, or may display prematurely, on vehicles using  
tires not recommended by Tesla. For more information on recommended tires, see Wheels and Tires on page 215.

Charging equipment communication error  
Try again or try different equipment  
What this alert means:  
Your vehicle is unable to charge because it cannot communicate effectively with the Mobile Connector. The Mobile  
Connector cannot confirm via proximity detection that the charge handle is fully connected to your vehicle.  
What to do:  
First, confirm the lack of effective communication is caused by the Mobile Connector rather than an issue with your  
vehicle. This is usually the case.  
To confirm this, try charging the vehicle using different external charging equipment.  
• If the vehicle begins charging, the issue was likely with the Mobile Connector.  
• If the vehicle still does not charge, the issue may be with the vehicle.  
Inspect the charge port inlet and the Mobile Connector handle for any obstructions (use a flashlight as necessary).  
Make sure any obstruction has been removed and any moisture has been allowed to dry, then try re-inserting the  
Mobile Connector handle into the charge port.  
This alert is usually specific to external charging equipment and power sources and does not typically indicate an  
issue with your vehicle that can be resolved by scheduling service.

See Maintaining Tire Pressures on page 184 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.
