Troubleshooting Alerts
(VCFRONT_a192)
Electrical system is unable to support all features
Shutting down features to conserve energy
The electrical system cannot support all vehicle features. Your vehicle is shutting down
nonessential features to preserve energy for essential functions.
If you are driving when this alert is present, it is possible your vehicle may shut down
unexpectedly. It is also possible that your vehicle will not restart once parked.
Nonessential features may be unavailable, including seat heaters, cabin climate control, and in-
vehicle entertainment. This is expected behavior intended to help your vehicle maintain
adequate electrical power for essential functions, including the ability to operate headlights,
windows and doors, hazard lights, and the front trunk (frunk).
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 #unique_678 on page

This alert may be present due to various vehicle conditions. For more information and further
recommended actions, check for other active vehicle alerts.

Electrical system is unable to support all features
Schedule service
The low voltage battery cannot provide the electrical support necessary to drive or continue
driving.
If this alert is present while you are driving, your vehicle needs to come to a stop as soon as
possible. Pull over safely at your earliest opportunity.
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.
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.

Electrical system backup power is unavailable
Vehicle will consume more energy while idle
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 202.
