What this alert means:
An abnormally large and sustained power draw while driving or Supercharging / DC Fast Charging has made your vehicle’s electrical system unable to support all features and functions.
Your vehicle will not restart until the electrical system has been serviced.
Cabin climate control and air vent positioning, powered trunk liftgate, and steering column adjustments may be limited or unavailable.
Other features and functions may also unavailable, or their performance may be affected. These include:
- Powered doors
- Powered windows
- Front seat (movement and heating)
- Rear seat heaters
- Side mirror movement
What to do:
It is recommended that you schedule service at your earliest opportunity. Without service, your vehicle will remain unable to restart, and the electrical system will remain unable to support all features and functions.
Some or all of the powered doors and windows in your vehicle may lose electrical power. If this occurs, you can still use the manual door releases to exit the vehicle if necessary. For more information, see Opening Doors from the Interior.
What this alert means:
The low voltage battery is not available and cannot provide electrical support for vehicle features.
It is possible your vehicle will shut down unexpectedly. It is also possible that your vehicle will not restart after the current drive.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle preserving energy for essential functions.
What to do:
It is recommended that you eliminate or reduce your use of any nonessential features. This can help your vehicle maintain adequate electrical power for essential functions other than driving, until it can be serviced.
If this alert remains present, it is recommended that you schedule service immediately. Without service, your vehicle may not drive, may shut down unexpectedly, or may not restart.
What this alert means:
The backup power source for the electrical system, the low voltage battery, is not available or cannot provide the voltage required to support all vehicle features.
The primary source of electrical power, the high voltage battery system, will continue to support vehicle functions, even when your vehicle is idle. For more information on the high voltage battery, see High Voltage Battery Information.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle preserving energy for essential functions.
You may also notice that your vehicle consumes more energy than usual when you are not driving it, or that your vehicle displays a lower projected range than you would normally expect after charging. This is normal vehicle behavior when this alert is present, and it will continue until the backup power source is restored.
There is a chance that an issue affecting the primary power source could cause your vehicle to shut down unexpectedly.
What to do:
It is recommended that you limit or avoid the use of any nonessential features. This can help your vehicle maintain adequate electrical power for essential functions.
It is recommended that you schedule service at your earliest opportunity, so the backup power source for the electrical system can be restored.
What this alert means:
The electrical system cannot provide adequate support to drive or continue driving. Your vehicle is preparing to shut down to preserve energy for essential functions other than driving.
Your vehicle cannot be driven or continue driving while this condition continues.
What to do:
- Pull over safely at your earliest opportunity
- Use your Mobile App to contact Tesla Roadside Assistance immediately, or seek other roadside assistance if preferred
If you do not pull over safely within a short time, your vehicle may shut down unexpectedly. It is also possible that your vehicle will not restart once parked.
It is possible your vehicle may lose all electrical power. If this occurs, you can still use the manual door releases to exit the vehicle if necessary. For more information, see Opening Doors from the Interior.
This alert may be present due to various vehicle conditions. For more information and further recommended actions, check for other active vehicle alerts.

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 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.
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 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 Tesla Mobile App.
See Maintaining Tire Pressures 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.
The alert should clear once the Tire Pressure Monitoring System has a consistent tire pressure measurement for each of your tires of at least 30 psi.
- 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.
