While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering
wheel controls if the vehicle has them.
Notice:Before adding any sound equipment
to your vehicle, such as an audio system,
CD player, CB radio, mobile telephone,
or two-way radio, make sure that it can be
added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be
added, it is very important to do it properly.
Added sound equipment may interfere with the
operation of your vehicle’s engine, radio, or
other systems, and even damage them.
Your vehicle’s systems may interfere with the
operation of sound equipment that has
been added.Notice:The chime signals related to safety
belts, parking brake, and other functions of
your vehicle operate through the radio/
entertainment system. If that equipment is
replaced or additional equipment is added to
your vehicle, the chimes may not work. Make
sure that replacement or additional equipment
is compatible with your vehicle before installing
it. SeeAccessories and Modifications on
page 341.
Your vehicle has a feature called Retained
Accessory Power (RAP). With RAP, the audio
system can be played even after the ignition is
turned off. SeeRetained Accessory Power (RAP)
on page 110for more information.
Setting the Time
Press and hold H until the correct hour appears on
the display. AM or PM will appear on the display
(Radio with CD (UpLevel, MP3, and Six-Disc CD)).
Press and hold M until the correct minute
appears on the display. The time can be set with
the ignition on or off.
239

When the system activates, a STABILITY
CONTROL ACTIVE message will be displayed on
the Driver Information Center (DIC). SeeDIC
Warnings and Messages on page 208. You may
also hear a noise or feel vibration in the brake
pedal. This is normal. Continue to steer the vehicle
in the direction you want it to go.
If there is a problem detected with StabiliTrak
®,a
SERVICE STABILITY SYSTEM or STABILITY
CONTROL OFF message will be displayed on the
Driver Information Center (DIC). A warning light
will also appear on the instrument panel cluster.
SeeDIC Warnings and Messages on page 208.
When this message is displayed, the system is not
operational. Driving should be adjusted
accordingly.
If your vehicle is in cruise control when the
StabiliTrak
®activates, the cruise control will
automatically disengage. When road conditions
allow you to safely use it again, you may reengage
the cruise control. SeeCruise Control on
page 154for more information.
Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning, you
can steer but it will take much more effort.
Steering Tips
It is important to take curves at a reasonable
speed.
A lot of the “driver lost control” accidents mentioned
on the news happen on curves. Here is why:
Experienced driver or beginner, each of us is
subject to the same laws of physics when driving on
curves. The traction of the tires against the road
surface makes it possible for the vehicle to change
its path when you turn the front wheels. If there is
no traction, inertia will keep the vehicle going in the
same direction. If you have ever tried to steer a
vehicle on wet ice, you will understand this.

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 350
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.
353

5. Then ll the coolant recovery tank to the
cold ll line.
6. Reinstall the coolant recovery tank cap and
the pressure cap.
7. If the coolant in the recovery tank is constantly
low, you should have your dealership service
department inspect the vehicle for leaks.
Power Steering Fluid
SeeEngine
Compartment Overview
on page 350for
reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power
steering uid unless you suspect there is a leak
in the system or you hear an unusual noise.
A uid loss in this system could indicate a problem.
Have the system inspected and repaired.
378

How to Check Power Steering Fluid
To check the power steering uid, do the following:
1. Turn the key off and let the engine
compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with
a clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the
uid level on the dipstick.
If your vehicle has the 3.8L V6 engine, the uid
level should be between the ADD and HOT marks
when the engine is cold, and at the HOT mark
when the engine is hot. If the uid is at the
ADD mark when the engine is cold or hot, power
steering uid should be added.If your vehicle has the 3.6L V6 engine, the uid
level should be between the Min (Minimum)
and Max (Maximum) marks when the engine is
cold, and at the Max mark when the engine is hot.
If the uid is at the Min mark when the engine
is cold or hot, power steering uid should be
added.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 470.
Always use the proper uid. Failure to use the
proper uid can cause leaks and damage hoses
and seals.

(C) Aspect Ratio:A two-digit number that
indicates the tire height-to-width measurements.
For example, if the tire size aspect ratio is 60,
as shown in item C of the illustration, it would
mean that the tire’s sidewall is 60 percent as high
as it is wide.
(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire. The
letter R means radial ply construction; the letter D
means diagonal or bias ply construction; and the
letter B means belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in
inches.
(F) Service Description:These characters
represent the load range and speed rating of the
tire. The load index represents the load carry
capacity a tire is certied to carry. The load index
can range from 1 to 279. The speed rating is
the maximum speed a tire is certied to carry a
load. Speed ratings range from A to Z.Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission/
transaxle, power steering, power brakes, power
windows, power seats, and air conditioning.
Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is
located between the plies and the tread. Cords
may be made from steel or other reinforcing
materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
