This procedure only changes the mode for the transmitter used to change this setting. The procedure will need to be repeated for the second transmitter. If your vehicle is equipped with the Driver Information Center (DIC), you must program this feature through the DIC. See "Driver Information Center" in the Index. Exterior Lighting Battery Saver If the manual lamp control has been left on, the exterior lamps will turn off approximately 10 minutes after the ignition is turned to LOCK and any door has been opened. This protects draining the battery in case you have accidentally left the headlamps or parking lamps on. If you need to leave the lamps on for more than 10 minutes, use the manual control to turn the lamps back on after the ignition is turned to LOCK and any door is opened. To delay the lamps from turning off, see "Twilight SentinelR" in the index. Battery Load Management The battery load management feature is designed to monitor the vehicle's electrical load and determine when the battery is in a heavy discharge condition. During times of high electrical loading, the engine may idle at a higher rpm setting than normal to make sure the battery charges. High electrical loads may occur when several of the following are on: headlamps, high beams, rear window defogger, high blower fan, heated seats (if equipped) and engine cooling fans. If your vehicle's battery remains in a heavy discharge condition for a long period of time, the blower fan, rear defogger, heated seats and heated mirrors will be disabled and the DIC will display BATTERY SAVER ACTIVE. This can happen either under long periods of idling or low speed driving with high electrical loading, or in the event of a charging system fault. 2-49
