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.

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.

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 Sentinel
