Playing a CD (Single CD Player)
Insert a CD partway into the slot, label side up.
The player pulls it in and the CD should begin playing.
If the ignition or radio is turned off with a CD in the
player, it stays in the player. When the ignition or radio
is turned on, the CD starts playing where it stopped,
if it was the last selected audio source.
When a CD is inserted, the CD symbol displays.
As each new track starts to play the track number
displays.
Care of CDs
If playing a CD-R, the sound quality can be reduced due
to CD-R quality, the method of recording, the quality of
the music that has been recorded, and the way the CD-R
has been handled. Handle them carefully. Store CD-R(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, take a soft, lint free
cloth or dampen a clean, soft cloth in a mild, neutral
detergent solution mixed with water, and clean it.
Make sure the wiping process starts from the center
to the edge.
Care of The CD Player
Do not add any label to a CD, it could get caught in the
CD player. 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, or 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 Messages” later in this
section.

Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on at or rolling terrain. Tips for driving
in these conditions include:
Keep the vehicle serviced and in good shape.
Check all uid levels and brakes, tires, cooling
system, and transmission.
Going down steep or long hills, shift to a
lower gear.
{CAUTION:
If you do not shift down, the brakes 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. Shift down to let the engine
assist the brakes on a steep downhill slope.
{CAUTION:
Coasting downhill in N (Neutral) or with the ignition
off is dangerous. The brakes will have to do all the
work of slowing down and 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 the engine running
and the vehicle in gear when going downhill.
Stay in your own lane. Do not swing wide or cut
across the center of the road. Drive at speeds
that let you stay in your own lane.
Top of hills: Be alert — something could be in your
lane (stalled car, accident).
Pay attention to special road signs (falling rocks
area, winding roads, long grades, passing or
no-passing zones) and take appropriate action.

If you put things inside your vehicle, like suitcases,
tools, packages, or anything else, they will go
as fast as the vehicle goes. If you have to stop or
turn quickly, or if there is a crash, they will keep
going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the trunk of your vehicle.
In a trunk, put them as far forward as you
can. Try to spread the weight evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that some
of them are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Automatic Level Control
This feature keeps the rear of your vehicle level
as the load changes. It is automatic, you do
not need to adjust anything.
This type of level control is fully automatic and will
provide a better leveled riding position as well
as better handling under a variety of passenger
and loading conditions. An air compressor
connected to the rear shocks will raise or lower
the rear of the vehicle to maintain proper vehicle
height. The system is activated when the
ignition key is turned to ON/RUN and will
automatically adjust vehicle height thereafter.
The system may exhaust (lower vehicle height)
for up to ten minutes after the ignition key
has been turned to LOCK/OFF. You may hear the
air compressor operating when the height is
being adjusted.

Dinghy Towing
Notice:If the vehicle is towed with all four wheels
on the ground, the drivetrain components could
be damaged. The repairs would not be covered by
the vehicle warranty. Do not tow the vehicle with all
four wheels on the ground.
The vehicle was not designed to be towed with all
four wheels on the ground. Use a dolly if the vehicle
must be towed. See “Dolly Towing” later in this section
for more information.
Dolly Towing
The vehicle can be towed using a dolly. To tow the
vehicle using a dolly, follow these steps:
1. Put the front wheels on a dolly.
2. Put the gear shift lever in P (Park).
3. Set the parking brake.
4. Clamp the steering wheel in a straight-ahead
position with a clamping device designed for towing.
5. Remove the key from the ignition.
6. Secure the vehicle to the dolly.
7. Release the parking brake.

Brakes
Brake Fluid
The brake master cylinder
reservoir is lled with DOT
3 brake uid. SeeEngine
Compartment Overview on
page 5-12for reservoir
location and access.
There are only two reasons why the brake uid level in
the reservoir might go down:
The brake uid level goes down because of normal
brake lining wear. When new linings are installed,
the uid level goes back up.
A uid leak in the brake hydraulic system can also
cause a low uid level. Have the brake hydraulic
system xed, since a leak means that sooner
or later the brakes will not work well.Do not top off the brake uid. Adding uid does not
correct a leak. If uid is added when the linings
are worn, there will be too much uid when new brake
linings are installed. Add or remove brake uid, as
necessary, only when work is done on the brake
hydraulic system.
{CAUTION:
If too much brake uid is added, it can spill on the
engine and burn, if the engine is hot enough. You
or others could be burned, and the vehicle could
be damaged. Add brake uid only when work is
done on the brake hydraulic system.
If the ignition is on and the brake uid is low, the
SERVICE BRAKE SYSTEM message displays in the
Driver Information Center (DIC). SeeDIC Warnings and
Messages on page 3-73.

Notice:If you leave the radio or other accessories
on during the jump starting procedure, they could be
damaged. The repairs would not be covered by the
warranty. Always turn off the radio and other
accessories when jump starting the vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlets. Turn off
the radio and all lamps that are not needed. This
will avoid sparks and help save both batteries. And
it could save the radio!
4. Open the hoods and locate the positive (+) and
negative (−) terminal locations on the other vehicle.
Your vehicle has a remote positive (+) jump starting
terminal and a remote negative (−) jump starting
terminal.The remote positive (+) terminal is located in the
engine compartment on the passenger’s side of the
vehicle. Lift the red plastic cap to access the terminal.
SeeEngine Compartment Overview on page 5-12
for more information on the location of the remote
positive (+) terminal.
A second remote positive (+) terminal is located on
the rear underseat fuse block.
The remote negative (−) terminal is located behind
the power steering pulley, near the engine cover.
It is marked GND (−). 4.6L LD8 Engine shown,
