Electrical system power reduced
Vehicle may shut down unexpectedly
The electrical system cannot maintain the voltage required to support all vehicle features.
If this alert is present while you are driving, it is possible your vehicle will shut down
unexpectedly. It is also possible that your vehicle will not restart after the current drive.
If this alert is present when your vehicle is in Park or when it first wakes, it is possible your
vehicle may not have adequate electrical power to start driving. A separate vehicle alert may be
present to indicate that condition.
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.
If this alert remains active, it is recommended that you schedule service immediately. Without
service, your vehicle may not drive, may shut down unexpectedly, or may not restart.

that offers low voltage battery replacement for your vehicle. Please note that independent
service provider options may vary, based on your vehicle configuration and your location.
Your vehicle is OK to drive with this alert present. However, if you delay the low voltage battery
replacement, your vehicle may eventually not have enough electrical power to start or to restart
after a recent drive.
If the low voltage battery does not have enough electrical power to turn on your vehicle or open
the doors, follow the instructions in
Jump Starting the Low Voltage Battery on page
