Battery Rundown Protection

The battery rundown protection function helps to prevent the battery from deep discharge due to interior/courtesy lighting being inadvertently left ON. The battery rundown function performs this function by turning OFF the inadvertent power output. The power output provides power for the interior/courtesy lighting.

When the ignition switch is turned to the OFF position one of the following time out period starts:
^ 3 minutes when the odometer is less than 24 km (15 miles)
^ 20 minutes when the odometer is greater than 24 km (15 miles)

When the time out expires, the inadvertent power output is turned off.
