Rear Seat Audio (RSA)
This feature allows rear seat passengers to select and
listen to any of the available radio sources: AM/FM,
XM, CD, or DVD. However, a rear seat passenger
cannot control a source selected on the radio by
someone in the front of the vehicle. For example, the
RSA cannot be used to change CD tracks if the radio is
set to CD. Also, if the radio is switched to a source
the RSA has control of, sound will not be lost, but the
RSA will lose control of that sourse.
Rear seat passengers always have control of the
volume for each set of headphones.
The RSA will run when the radio is off if the ignition key
is positioned in the power mode, seeIgnition Positions
on page 2-20in this manual.
P(Power):Press this button to turn the RSA on or
off. The rear speakers are muted when the power
is turned on.
u(Volume):The left-hand knob controls the
headphone outlet on the left and the right-hand knob
controls the headphone outlet on the right. Turn
either knob clockwise to increase the volume and
counterclockwise to decrease the volume.

Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away, your
anti-lock brake system will check itself. You may hear a
momentary motor or clicking noise while this test is going
on. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-34.
Along with ABS, your vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP problem,
both the brake and ABS warning lights will 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 for service.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You
slam on the brakes and continue braking. Here is
what happens with ABS:
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at
both rear wheels.

{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Always have
your engine running and your vehicle in gear
when you go downhill.
Know how to go down hills. The most important thing
to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
Know how to go uphill. You may want to shift down to
a lower gear. The lower gears help cool your engine
and transmission, and you can climb the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or an
accident.
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing or no-passing zones, a falling rocks area, or
winding roads. Be alert to these and take appropriate
action.

Towing
Towing Your Vehicle
Consult your dealer or a professional towing service
if you need to have your disabled vehicle towed.
SeeRoadside Assistance Program on page 7-4.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle — such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” (towing your vehicle
with all four wheels on the ground) and “dolly towing”
(towing your vehicle with two wheels on the ground and
two wheels up on a device known as a “dolly”).
Your vehicle was not designed to be towed with any of its
wheels on the ground. If your vehicle must be towed, see
“Towing Your Vehicle” earlier in this section.
Notice:Towing an all-wheel-drive vehicle with all
four wheels on the ground, or even with only two
of its wheels on the ground, will damage drivetrain
components. Do not tow an all-wheel-drive vehicle
if any of its wheels will be on the ground.
Electronically Controlled Air
Suspension System
Your vehicle is equipped with an electronically controlled
air suspension system that automatically keeps your
vehicle level as you load and unload. The system
includes a compressor, two height sensors, and
two air springs supporting the rear axle.
The system also has an internal clock to prevent
overheating if the in ator is used for prolonged periods.
If the system overheats, all leveling function stops until
the system cools down. During this time, the indicator
light on the air in ator switch will be ashing.
The ignition has to be on for the system to in ate, in
order to raise the vehicle to the standard ride height after
loading. The system can lower the vehicle to the standard
ride height after unloading with the ignition on and also for
up to 30 minutes after the ignition has been turned off.
You may hear the compressor operating when you load
your vehicle, and periodically as the system adjusts the
vehicle to the standard ride height.
Load leveling will not function normally with the in ator
hose attached to the in ator outlet. Remove the in ator
hose from the outlet during loading and unloading.
If the vehicle is parked for an extended period of time,
some bleed down of the suspension is normal. Upon
starting the vehicle, proper height will be achieved.

Overload Protection
The air suspension system is equipped with overload
protection. Overload protection is designed to protect the
air suspension system, and it is an indicator to the driver
that the vehicle is overloaded. When the overload
protection mode is on, it will not allow damage to the air
compressor. However, do not overload the vehicle. See
Loading Your Vehicle on page 4-33.
If the suspension remains at a low height, the rear axle
load has exceeded GAWR (Gross Axle Weight Rating).
When the overload protection mode is activated, the
compressor operates for about 30 seconds to one minute
without raising the vehicle depending on the amount
of overload. This will continue each time the ignition
is turned on until the rear axle load is reduced
below GAWR.
Indicator Light
The indicator light on the in ator switch in the rear
passenger compartment also serves as an indicator
for internal system error. If the indicator light is ashing
without the load leveling function or the in ator being
active, turn off the ignition. The next day turn on the
ignition and check the indicator light. The vehicle can
be driven with the light ashing, but if it is you should
have the vehicle serviced as soon as possible.

Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlets, if equipped.
Turn off the radio and all lamps that are not needed.
This will avoid sparks and help to save both
batteries. And it could save the radio!
4. Open both hoods and locate the batteries. Find the
positive (+) and negative (−) terminals on each
battery. Your vehicle has a remote negative (−) jump
starting terminal. You should always use this remote
terminal instead of the terminal on the battery. The
remote negative (−) terminal is located on the front
engine lift bracket on vehicles with the 4.2L L6
engine or the engine accessory drive bracket for
vehicles with the 5.3L V8 engine, and is marked
GND (Ground). SeeEngine Compartment Overview
on page 5-12for more information on location.
{CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
ashlight if you need more light.
Be sure the battery has enough water. You do
not need to add water to the battery installed
in your new vehicle. But if a battery has ller
caps, be sure the right amount of uid is there.
If it is low, add water to take care of that rst.
If you do not, explosive gas could be present.
Battery uid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, ush the place
with water and get medical help immediately.
