Battery Saver Control
WARNING: This page is about a different car, the 2005 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
When the combination switch (lighting switch) is in the AUTO position, and the ignition switch is turned from ON or ACC to OFF, and one of the doors is opened, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps are turned off.
