To turn off the DRL lamps, turn the
exterior lamps control to the OFF
position and then release. For
vehicles first sold in Canada, the
transmission must be in the P (Park)
position before the DRL lamps can
be turned off.
Automatic Headlamp
System
When it is dark enough outside and
the headlamp switch is in AUTO,
the automatic headlamp system
turns on the headlamps along with
other lamps such as the taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights. The radio lights will
also be dim.
To turn off the automatic headlamp
system, turn the exterior lamps
switch to the off position and then
release. For vehicles first sold in
Canada, the transmission must be
in the P (Park) position, before the
automatic headlamp system can be
turned off.The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover this sensor or
the system will come on whenever
the ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage, a tunnel, or while
driving in heavy overcast weather.
This is normal.There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp systems so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system is only affected
when the light sensor sees a
change in lighting lasting longer
than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately.
Once the vehicle leaves the garage,
it takes approximately one minute
for the automatic headlamp system
to change to DRL if it is light
outside. During that delay, the
instrument panel cluster may not be
as bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control on page 6‑7.

Fog Lamps
If your vehicle has fog lamps you
can use them for better vision in
foggy or misty conditions. Your
parking lamps and/or low-beam
headlamps must be on for your fog
lamps to work.

lamps in the dark without turning on
the headlamps.
The fog lamps will go off whenever
your high-beam headlamps come
on. When the high beams go off, the
fog lamps will come on again.
The fog lamps will be cancelled
after the ignition is turned off. If you
still want to use the fog lamps after
you restart the vehicle, you will need
to press the fog lamp button again.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.Exterior Cargo Lamps
The cargo lamp can be used if more
light is needed in the cargo area of
the vehicle or in the top-box storage
units. Some vehicles will only have
a cargo lamp in the driver side
top box.
The cargo lamps come on by
turning on the interior dome lamps.

Lighting Features
Entry/Exit Lighting
The vehicle has an illuminated
entry/exit feature.
The dome lamps come on if
the
EDOME OFF button is in the
extended position, when a door is
opened or the key is removed from
the ignition.
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.
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. See
Battery Voltage and
Charging Messages on page 5‑36.
Battery Power Protection
This feature shuts off the dome
lamps if they are left on for more
than 10 minutes when the ignition is
in LOCK/OFF. This helps to prevent
the battery from running down.

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
“CD Player
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
seconds, the disc is automatically
pulled back into the player.
