Battery Saver

WARNING: This page is about a different variant/trim than selected.
NOTE: Time-out is 1 minute if the vehicle has less than 80 km (50 miles).

The SJB provides automatic shut-off of the demand lamps and courtesy lamps after a 10-minute time-out period in order to save battery voltage. A timer in the SJB is started when the ignition is turned to the OFF position and all the doors are closed. When 10 minutes have elapsed, voltage is automatically shut off to the lamps by the SJB. While the SJB has voltage disabled, if the ignition is turned to any position other than OFF, any door becomes ajar, the UNLOCK button of the Remote Keyless Entry (RKE) transmitter is pressed or the instrument panel dimmer switch is rotated to the DOME LAMP position, the SJB restores voltage and starts the timer again.
