Lighting Features
Entry Lighting
The vehicle has an illuminated entry
feature.
When the doors are opened, the
dome lamps will come on if the
dome override button is in the
extended position. If the dome
override button is pressed in, the
lamps will not come on.
Exit Lighting
The interior lamps come on when
the key is removed from the ignition.
They turn off automatically in
20 seconds. The lights do not come
on if the dome override button is
pressed in.
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 that is 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
needed. It can temporarily reduce
the power demands of some
accessories.

6-10 Lighting
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a Driver Information
Center (DIC) message might be
displayed, such as BATTERY LOW
START VEHICLE . If this message
displays, it is recommended that the
driver reduce the electrical loads as
much as possible and restart the
vehicle. SeeBattery Voltage and
Charging Messages on page 5‑38.Battery Power Protection
This feature shuts off the dome, and
reading lamps if they are left on for
more than 10 minutes when the
ignition is off. This will keep the
battery from running down.

7-2 Infotainment System
To minimize taking your eyes off the
road while driving, do the following
while the vehicle is parked:
.Become familiar with the
operation and controls of the
audio system.
.Set up the tone, speaker
adjustments, and preset radio
stations.
For more information, see Defensive
Driving on page 9‑2. This vehicle's audio system may be
equipped with a noise reduction
system which can work improperly
if the audio amplifier, engine
calibrations, exhaust system,
microphones, radio, or speakers are
modified or replaced. This could
result in more noticeable engine
noise at certain speeds.
Notice:
Contact your dealer
before adding any equipment.
Adding audio or communication
equipment could interfere with
the operation of the engine, radio,
or other systems, and could
damage them. Follow federal
rules covering mobile radio and
telephone equipment. The vehicle has Retained
Accessory Power (RAP). With RAP,
the audio system can be played
even after the ignition is turned off.
See
Retained Accessory Power
(RAP) on page 9‑33 for more
information.Navigation/Radio System
For vehicles with a navigation radio
system, see the separate Navigation
System manual.

under,
“Adjusting the Speakers
(Balance/Fade)”.
Vehicles with a USB, CD, and
DVD radio may have a Rear Seat
Entertainment (RSE) system. See
Rear Seat Entertainment (RSE) System on page 7‑35
for more
information on the vehicle's RSE
system.

Audio Players
CD Player
Care of the CD Player
Do not add any label to a CD.
It could get caught in the CD. If a
CD is recorded on a personal
computer and a description label is
needed, try labeling the top of the
recorded CD with a marking pen.
The use of CD lens cleaners for
CDs is not advised, due to the risk
of contaminating the lens of the CD
optics with lubricants internal to the
CD player mechanism.
Notice:If a label is added to a
CD, more than one CD is inserted
into the slot at a time, or an
attempt is made to play scratched
or damaged CDs, the CD player
could be damaged. While using
the CD player, use only CDs in
good condition without any label,
load one CD at a time, and keep the CD player and the loading slot
free of foreign materials, liquids,
and debris.
If an error displays, see
“
Messages” later in this section.Care of CDs
If playing a CD-R, the sound quality
can be reduced due to CD-R or
CD-RW quality, the method of
recording, the quality of the music
that has been recorded, and the
way the CD-R or CD-RW has been
handled. Handle them carefully.
Store CD-R(s) or CD-RW(s) in their
original cases or other protective
cases and away from direct sunlight
and dust. The CD player scans the
bottom surface of the disc. If the
surface of a CD is damaged, such
as cracked, broken, or scratched,
the CD does not play properly or not
at all. Do not touch the bottom side
of a CD while handling it; this could
damage the surface. Pick up CDs
by grasping the outer edges or the
edge of the hole and the outer edge. If the surface of a CD is soiled,
clean it with a soft, lint free cloth or
dampen a clean, soft cloth in a mild,
neutral detergent solution mixed
with water. Make sure the wiping
process starts from the center to
the edge.Inserting a CD
Insert a CD partway into the slot,
label side up. The player pulls it in
and the CD should begin playing.
Ejecting a CD
ZEJECT:
Press and release to
eject the disc. Remove the CD
when Remove Disc displays. If the
disc is not removed, after several

pulled back into the player.
Playing a CD
If the ignition or radio is turned off,
with a CD in the player, it stays in
the player. When the ignition or
