Battery Saver
Your Chevrolet is equipped with a battery saver feature
designed to protect your vehicle's battery.
When any interior lamp (trunk, reading, dome, glove
box, etc.) is left on and the ignition is turned OFF, the
battery rundown protection system will automatically
turn the lamp off after 20 minutes. This will avoid
draining the battery. This system does not protect
against leaving on the headlamps.
