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 on page 14.

Electrical system is unable to support all features
Schedule service
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.
VCFRONT_a402
Electrical system backup power is unavailable
Vehicle will consume more energy while idle
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
About the High Voltage Battery
on page 167.
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.
