Care of CDs and DVDs
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
or DVD player scans the bottom surface of the disc.
If the surface of a CD or DVD is damaged, such as
cracked, broken, or scratched, the CD or DVD does not
play properly or not at all. Do not touch the bottom side
of a CD or DVD 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 or DVD 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.

Headphones
The RSE includes two 2-channel wireless headphones
that are dedicated to this system. Channel 1 is
dedicated to the DVD player, while Channel 2 is
dedicated to RSA selections. These headphones can
be used to listen to the radio, CDs, DVDs, MP3s,
DVDAs, any auxiliary source connected to A/V jacks,
or the auxiliary input jack, if the vehicle has this feature.
The wireless headphones have an On/Off button,
channel 1/2 switch, and a volume control.
Push the power button to turn on the headphones. An
indicator light located on the headphones comes on.
If the light comes on but, there is intermittent sound
and/or static on the headphones, or if the indicator light
does not come on, the batteries might need to be
replaced. See“Battery Replacement” later in this
section for more information. Switch the headphones to
Off when not in use.
Infrared transmitters are located at the rear of the RSE
overhead console. The headphones shut off
automatically to save the battery power if the RSE
system and RSA are shut off or if the headphones are out of range of the transmitters for more than
three minutes. If you move too far forward or step out of
the vehicle, the headphones lose the audio signal.
The headphones may automatically turn off after
four hours of continuous use.
To adjust the volume on the headphones, use the
volume control located on the right side.
For optimal audio performance, the headphones must
be worn correctly. Headphones should be worn with
headband over the top of the head for best audio
reception. The symbol L (Left) appears on the upper left
side, above the ear pad and should be positioned on
the left ear. The symbol R (Right) appears on the upper
right side, above the ear pad and should be positioned
on the right ear.
Notice:
Do not store the headphones in heat or
direct sunlight. This could damage the headphones
and repairs will not be covered by the warranty.
Storage in extreme cold can weaken the batteries.
Keep the headphones stored in a cool, dry place.
If the foam ear pads attached to the headphones
become worn or damaged, the pads can be replaced
separately from the headphone set. Refer to your
dealer/retailer for more information.

Avoid needless heavy braking. Some people drive in
spurts, heavy acceleration followed by heavy braking,
rather than keeping pace with traffic. This is a mistake.
The brakes might not have time to cool between hard
stops. The brakes will wear out much faster with a lot of
heavy braking. Keeping pace with the traffic and
allowing realistic following distances eliminates a lot of
unnecessary braking. That means better braking and
longer brake life.
If the engine ever stops while the vehicle is being
driven, brake normally but do not pump the brakes.
If the brakes are pumped, the pedal could get harder to
push down. If the engine stops, there will still be some
power brake assist but it will be used when the brake is
applied. Once the power assist is used up, it can take
longer to stop and the brake pedal will be harder
to push.
Adding non‐dealer/non‐retailer accessories can affect
vehicle performance. SeeAccessories and
Modifications on page 6‑4.Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that helps prevent
a braking skid.
When the engine is started and the vehicle begins to
drive away, ABS checks itself. A momentary motor or
clicking noise might be heard while this test is going on.
This is normal.
If there is a problem with
ABS, this warning light
stays on. See Antilock
Brake System (ABS)
Warning Light
on
page 4‑36.
Along with ABS, the vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP problem,
both the brake and ABS warning lights come on
accompanied by a 10‐second chime. The lights and
chime will come on each time the ignition is turned on
until the problem is repaired. See your dealer/retailer for
service.

Driving in Water
{WARNING:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown. If it is
only shallow water, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Do not drive
through rushing water.
Heavy rain can mean flash flooding, and flood waters
demand extreme caution.
Find out how deep the water is before driving through it.
Do not try it if it is deep enough to cover the wheel
hubs, axles, or exhaust pipe —you probably will not get
through. Deep water can damage the axle and other
vehicle parts.
If the water is not too deep, drive slowly through it. At
faster speeds, water splashes on the ignition system
and the vehicle can stall. Stalling can also occur if you
get the tailpipe under water. If the tailpipe is under
water, you will never be able to start the engine. When
going through water, remember that when the brakes
get wet, it might take longer to stop. See Driving in Rain
and on Wet Roads on page 5‑24.
After Off-Road Driving
Remove any brush or debris that has collected on the
underbody, chassis, or under the hood. These
accumulations can be a fire hazard.
After operation in mud or sand, have the brake linings
cleaned and checked. These substances can cause
glazing and uneven braking. Check the body structure,
steering, suspension, wheels, tires, and exhaust system
for damage and check the fuel lines and cooling system
for any leakage.
The vehicle requires more frequent service due to
off-road use. Refer to the Maintenance Schedule for
additional information.
