rearview mirror. Push the button to turn the reading
lamps on and off. The reading lamps will
automatically come on when a door is open.
Rear Reading Lamps
Push the lens to turn the reading lamps on
and off.
Electric Power Management
The vehicle has Electric Power Management
(EPM) that estimates the battery's temperature and
state of charge. It then adjusts the voltage for
best performance and extended life of the battery.
When the battery's state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC), you
may see the voltage move up or down. This is
normal. If there is a problem, an alert will be
displayed.

The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator's
output and the vehicle's electrical needs.
It can increase engine idle speed to generate
more power, whenever needed.
Battery Run-Down Protection
Your vehicle has a battery saver feature designed
to protect your vehicle's battery.
When any interior lamp is left on and the ignition
is turned off, the battery rundown protection
system will automatically turn the lamp off after
20 minutes. This will avoid draining the battery.
