Battery Rundown Protection
Your Pontiac is equipped with a Battery
Rundown Protection feature designed to
protect your vehicle's battery.
When any interior light (trunk, reading,
footwell or glove box) is left on when
the ignition is turned off, the Battery
Rundown Protection system will
automatically shut the light off after 20
minutes. This will avoid draining the
battery.
To reactivate the interior lights, either:
The ignition must be turned on
The activated light switch must be
turned off and then on, OR
A front door must be opened.
The Battery Rundown Protection feature
will also be activated when any door of
your vehicle is left open.
Also, if your vehicle is left with the
ignition turned off for over 24 days,
battery power to your clock and audio
system will be turned off to reduce
battery drain. When the ignition is
turned on again, battery power will be
resupplied. However, under these
conditions, it will be necessary to reset
the clock and audio system settings.
