The exterior and interior lamps remain on for a set amount of time, then automatically turn off. If equipped with Keyless Access, the exterior lamps automatically turn on when the driver door is opened after the vehicle is powered off.
The interior lights turn on when the vehicle is powered off.
The exterior lamps turn off immediately by turning the exterior lamp control off.
Battery Power Protection
This feature helps prevent the battery from being drained if the interior courtesy lamps or reading lamps are accidentally left on. If any of these lamps are left on, they automatically turn off after 10 minutes if the ignition is off. The lamps will not come back on again until one of the following occurs:
- The vehicle is powered on.
- The doors are closed and then re-opened.
Battery Saver
The vehicle is equipped with electrical power management (EPM). EPM monitors and controls the charging system. The message BATTERY SAVER ACTIVE displays on the Driver Information Center (DIC) when the EPM detects the battery may be draining too quickly, the charge state needs to be reset, or the Auxiliary Power Module failed.
If safe to do so, when BATTERY SAVER ACTIVE displays, manually shut off windshield wipers, communications equipment, climate controls, etc. to slow the battery from draining.
If the message still displays, fully charge the vehicle. Once fully charged, unplug the vehicle and let the vehicle sit an additional 8.5 hours or greater without being interrupted to allow the Body Control Module (BCM) to reset the battery to the required state of charge.
The following may interrupt the vehicle:
- Charging the vehicle . Battery Maintenance Mode
- Approach Detection is activated .
- The Key Fob is left in the car or left in close proximity of the vehicle .
- Pressing buttons on the Remote Keyless Entry (RKE) transmitter .
- Opening the doors or tailgate
To reduce the occurrence of this alert, GM recommends letting the vehicle sit uninterrupted for 8.5 hours or greater on a weekly basis.
If after completing this process the BATTERY SAVER ACTIVE message remains, see your dealer for service.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes after the ignition is turned off, if the parking lamps or headlamps have been manually left on. This protects against draining the battery. To restart the 10-minute timer, turn the exterior lamp control to the 
position and then back to the 
or 
position.
To keep the lamps on for more than 10 minutes, the vehicle must be powered on or in ACC/ACCESSORY.
