yellowblue Battery Load Management The battery load management feature is designed to monitor the vehicle 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. Front Reading Lamps 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 OFF/LOCK. 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. To delay the lamps from turning off, see "Twilight SentinelR" in the index. Front seat reading lamps are turned on or off by pressing one of the lamps buttons. Inadvertent Power Battery Saver This feature is designed to protect your vehicle's battery against drainage from the interior lamps, trunk lamp, glove box lamp, cigarette lighters or garage door opener. When the ignition is turned off, the power to these features will automatically turn off after 10 minutes. Power will be restored for an additional 10 minutes if any door is opened, the trunk is opened or the courtesy lamp switch is turned on. To restore power back to the cigarette lighters the ignition must be turned back to RUN. 2-49
