Vehicle Speakers
Only one audio source can be heard through the
vehicle’s speakers at a time. The audio source
being used is specied by the A/V (audio/video)
source selected on the driver’s side head restraint
monitor.
The RSE system or an auxiliary device can be
heard through all of the vehicle’s speakers when a
DVD or auxiliary device is playing and the radio
is tuned to one of eight frequencies selected
on the FM Modulator portion of the system’s
remote control. See “FM Modulator Control” later
in this section.
To turn the RSE system audio output to the
vehicle’s speakers, on or off, press the power
button on the FM Modulator portion of the system’s
remote control. The audio from the RSE system
can be heard through the wireless/wired
headphones and the vehicle’s speakers at the
same time. The volume on the radio can
vary when switching between the radio, CD, DVD,
MP3, or an auxiliary device.
Video Screens
The video screens are located on the backside of
each head restraint.
Notice:Avoid directly touching the video
screen, as damage may occur. See “Cleaning
the Video Screens” later in this section for
more information.
To use a video screen, do the following:

Infrared Remote Sensor:The infrared remote
sensor receives light signals from the system’s
remote control. The infrared remote sensor
is located on the upper right side of the monitor.
This sensor works as a line-of-sight signal as
the transmitted signals are received. In order for
the sensor to work properly, it must remain
unobstructed at all times.
Infrared LED (Light Emitting Diode) Window:
The infrared LED window sends audio signals
to the wireless headphones. The infrared
LED window is located on the lower front
monitor, surrounding the monitor’s faceplate
buttons. In order for the infrared LED window
to work properly, it must remain unobstructed
at all times.
X(Wired Headphone Jack):This type of
headphone jack is used with universal wired
headphones (not included). The wired headphone
volume is adjusted using the up and down
arrow buttons. See “Wired Headphones” earlier in
this section.AUX (Auxiliary):The auxiliary input jack is an
AV 3 input jack. The auxiliary input jack is located
on the left lower side of the monitor, next to the
wired headphone jack. This auxiliary input jack lets
you view auxiliary sources such as portable
DVD units, game stations, video cameras, etc., on
each individual monitor. The sources connected
to these inputs cannot be shared between
the monitors.
Press the SOURCE soft key button on either
monitor, or the SOURCE button on the system’s

Cleaning the Video Screens
The video display screens are made of a specially
coated glass and can be scratched or damaged
by abrasive products, solvents, or ammonia-based
window cleaners. Occasionally take a soft,
lint-free, cotton cloth that has been slightly
dampened with warm water and wrung out
completely. Dry the screens by wiping with a clean
dry cotton cloth.
293

Cleaning the Components
Use care when directly touching or cleaning the
components such as the DVD player and the discs
that are used for your viewing entertainment, as
damage may result. SeeCare of the CD and
DVD Player on page 300andCare of Your CDs
and DVDs on page 299in this manual for
more information.
Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen
to any of the sources: radio, cassette tapes, or
CDs. However, the rear seat passengers can only
control the sources that the front seat passengers
are not listening to. For example, rear seat
passengers may listen to and control cassette
tapes or CDs through the headphones while the
driver listens to the radio through the front
speakers. The rear seat passengers have control
of the volume for each set of headphones.
The front seat audio controls always have priority
over the RSA controls. If the front seat
passengers switch the source for the main radio to
a remote source, the RSA will not be able to
control the source. You can operate the rear seat
audio when the main radio is off.
P(Power):Press this button to turn the system
on or off. The rear speakers will be muted
when the power is turned on unless your vehicle
is equipped with the Bose
®audio system.
u(Volume):Turn this knob to increase or to
decrease the volume. The left knob controls
the left headphones and the right knob controls
the right headphones.
SRC (Source):Press this button to select a
source: radio, cassette tape, or CD.

Radio Reception
You may experience frequency interference and
static during normal radio reception if items
such as cellphone chargers, vehicle convenience
accessories, and external electronic devices
are plugged into the accessory power outlet. If
there is interference or static, unplug the item from
the accessory power outlet.
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range can cause
station frequencies to interfere with each other.
For better radio reception, most AM radio stations
boosts the power levels during the day, and then
reduce these levels during the night. Static can also
occur when things like storms and power lines
interfere with radio reception. When this happens,
try reducing the treble on your radio.
FM Stereo
FM stereo gives the best sound, but FM signals
reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals,
causing the sound to fade in and out.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite
radio signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy
foliage, bridges, garages, or tunnels can cause
loss of the XM™ signal for a period of time.
The radio could display NO SIGNAL to indicate
interference.
Care of the Cassette Tape Player
A tape player that is not cleaned regularly
can cause reduced sound quality, ruined
cassettes, or a damaged mechanism. Cassette
tapes should be stored in their cases away
from contaminants, direct sunlight, and extreme
heat. If they are not, they may not operate properly
or may cause failure of the tape player.

Before You Go Off-Roading
There are some things to do before you go out.
For example, be sure to have all necessary
maintenance and service work done. Check to
make sure all underbody shields are properly
attached. Remove any removable side steps.
SeeAssist Steps on page 338. Make sure any
equipment you may need — rst aid kit, cell phone,
ashlight, etc. — is securely stored in the vehicle.
Be sure you read all the information about your
four-wheel-drive vehicle in this manual. Is there
enough fuel? Is the spare tire fully inated? Are the
uid levels up where they should be? What are the
local laws that apply to off-roading where you will be
driving? If you do not know, you should check with
law enforcement people in the area. Will you be on
someone’s private land? If so, be sure to get the
necessary permission.
Loading Your Vehicle for Off-Road
Driving
{CAUTION:
Cargo on the load oor piled higher
than the seatbacks can be thrown
forward during a sudden stop. You or
your passengers could be injured.
Keep cargo below the top of the
seatbacks.
Unsecured cargo on the load oor can
be tossed about when driving over
rough terrain. You or your passengers
can be struck by ying objects.
Secure the cargo properly.
Heavy loads on the roof raise the
vehicle’s center of gravity, making it
more likely to roll over. You can be
seriously or fatally injured if the
vehicle rolls over. Put heavy loads
inside the cargo area, not on the roof.
Keep cargo in the cargo area as far
forward and low as possible.
318

{CAUTION:
Wet brakes can cause accidents. They may
not work as well in a quick stop and may
cause pulling to one side. You could lose
control of the vehicle.
After driving through a large puddle of
water or a car wash, apply your brake pedal
lightly until your brakes work normally.
Driving too fast through large water puddles or
even going through some car washes can cause
problems, too. The water may affect your brakes.
Try to avoid puddles. But if you cannot, try to slow
down before you hit them.
Hydroplaning
Hydroplaning is dangerous. So much water can
build up under your tires that they can actually ride
on the water. This can happen if the road is wet
enough and you are going fast enough. When your
vehicle is hydroplaning, it has little or no contact
with the road.
Hydroplaning does not happen often. But it can
if your tires do not have much tread or if the
pressure in one or more is low. It can happen if a
lot of water is standing on the road. If you can
see reections from trees, telephone poles,
or other vehicles, and raindrops dimple the water’s
surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds.
There just is not a hard and fast rule about
hydroplaning. The best advice is to slow down
when it is raining.
