window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof, if equipped.

Lighting 137
Lighting Features
Entry Lighting
Some exterior lamps and interior
lamps turn on briefly at night, or in
areas with limited lighting, when
K
is pressed on the Remote Keyless
Entry (RKE) transmitter. When a
door is opened, the interior lamps
come on if the dome lamp control is
in the Door position. They stay on
for about 20 seconds. When all of
the doors have been closed or the
ignition is turned on, they gradually
fade out.
This feature can be changed. See
“Vehicle Locator Lights”under
Vehicle Personalization 0129.
Exit Lighting
Some exterior lamps and interior
lamps come on at night, or in areas
with limited lighting, when the key is
removed from the ignition. The
exterior lamps and dome lamp
remain on for a set amount of time,
then automatically turn off. If equipped with Keyless Access,
the exterior lamps automatically turn
on when a door is opened after the
ignition is turned off. The dome
lamps also come on after the
ignition is turned off.
See
Ignition Positions (Key Access)
0 181 orIgnition Positions (Keyless
Access) 0183.
The exterior lamps turn off
immediately by turning the exterior
lamps control off.
This feature can be changed. See
Vehicle Personalization 0129.
Battery Load
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 bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to prevent overcharging. If the vehicle
has a voltmeter gauge or a 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 needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: 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
