is turned on, the CD starts to play where it stopped, if it
was the last selected audio source.When the CD is inserted, the CD symbol displays. As
each new track starts to play, the track number displays.
The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.
Care of Your 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 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.

Radio Reception
Frequency interference and static can occur during
normal radio reception if items such as cell phone
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 boost the power levels
during the day, and then reduce these levels during thenight. 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.
Cellular Phone Usage
Cellular phone usage may cause interference with the
vehicle’s radio. This interference may occur when
making or receiving phone calls, charging the phone’s
battery, or simply having the phone on. This interference
causes an increased level of static while listening to
the radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged as long as it is securely attached
to the base. If the mast becomes slightly bent, straighten
it out by hand. If the mast is badly bent, replace it.
Occasionally check to make sure the antenna is
tightened to its base. If tightening is required, tighten
by hand.

For persons under 21, it is against the law in every
U.S. state to drink alcohol. There are good medical,
psychological, and developmental reasons for
these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink alcohol and
then drive.
Medical research shows that alcohol in a person’s
system can make crash injuries worse, especially
injuries to the brain, spinal cord, or heart. This means
that when anyone who has been drinking — driver
or passenger — is in a crash, that person’s chance of
being killed or permanently disabled is higher than if the
person had not been drinking.
Control of a Vehicle
The following three systems help to control the vehicle
while driving — brakes, steering, and accelerator.
At times, as when driving on snow or ice, it is easy to
ask more of those control systems than the tires
and road can provide. Meaning, you can lose control of
the vehicle.
Adding non-dealer/non-retailer accessories can affect
vehicle performance. SeeAccessories and Modications
on page 6-3.
Braking
SeeBrake System Warning Light on page 4-27.
Braking action involves perception time and reaction
time. Deciding to push the brake pedal is perception
time. Actually doing it is reaction time.
Average reaction time is about three-fourths of a second.
But that is only an average. It might be less with one
driver and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination,
and eyesight all play a part. So do alcohol, drugs, and
frustration. But even in three-fourths of a second, a
vehicle moving at 100 km/h (60 mph) travels 20 m
(66 feet). That could be a lot of distance in an emergency,
so keeping enough space between the vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement
or gravel; the condition of the road, whether it is
wet, dry, or icy; tire tread; the condition of the brakes;
the weight of the vehicle; and the amount of brake force
applied.

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 Modications
on page 6-3.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
the ABS, this warning light
stays on. SeeAntilock
Brake System (ABS)
Warning Light on
page 4-28.
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 the 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.

Press and hold the
StabiliTrak button located
on the instrument panel
for more than five seconds
to turn off StabiliTrak
and part of the traction
control system.
The StabiliTrak light comes
on the instrument panel
cluster when the system is
turned off or requires
service.
For more information, seeStabiliTrak
®Indicator Light
on page 4-29.For your safety, the system can only be disabled when
the vehicle speed is less than 20 mph (32 km/h).
Three chimes will be heard and the StabiliTrak light
comes on.
To turn on the StabiliTrak system, press the StabiliTrak
button again. StabiliTrak will automatically turn back on
when the vehicle speed exceeds 20 mph (32 km/h). One
chime is heard and the StabiliTrak light will turn off.
When the StabiliTrak system has been turned off,
system noises may still be heard as a result of
the brake-traction control coming on.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if the vehicle is stuck in sand, mud, ice or
snow, and you want to “rock” the vehicle to attempt to
free it. SeeIf Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 5-18.

Off-Road Recovery
The vehicle’s right wheels can drop off the edge of a
road onto the shoulder while driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way, steer
so that the vehicle straddles the edge of the pavement.
Turn the steering wheel 8 to 13 cm (3 to 5 inches), about
one-eighth turn, until the right front tire contacts the
pavement edge. Then turn the steering wheel to go
straight down the roadway.
Passing
Passing another vehicle on a two-lane road can be
dangerous. To reduce the risk of danger while passing:
•Look down the road, to the sides, and to crossroads
for situations that might affect a successful pass.
If in doubt, wait.
•Watch for traffic signs, pavement markings, and
lines that could indicate a turn or an intersection.
Never cross a solid or double-solid line on your side
of the lane.
•Do not get too close to the vehicle you want to
pass. Doing so can reduce your visibility.
•Wait your turn to pass a slow vehicle.
•When you are being passed, ease to the right.
Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough friction
where the tires meet the road to do what the driver has
asked.
In any emergency, do not give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.

Driving at Night
Night driving is more dangerous than day driving because
some drivers are likely to be impaired — by alcohol or
drugs, with night vision problems, or by fatigue.
Night driving tips include:
•Drive defensively.
•Do not drink and drive.
•Reduce headlamp glare by adjusting the inside
rearview mirror.
•Slow down and keep more space between you and
other vehicles because headlamps can only light up
so much road ahead.
•Watch for animals.
•When tired, pull off the road.
•Do not wear sunglasses.
•Avoid staring directly into approaching headlamps.
•Keep the windshield and all glass on your vehicle
clean — inside and out.
•Keep your eyes moving, especially during turns or
curves.
No one can see as well at night as in the daytime. But, as
we get older, these differences increase. A 50-year-old
driver might need at least twice as much light to see the
same thing at night as a 20-year-old.

Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction
and affect your ability to stop and accelerate. Always
drive slower in these types of driving conditions
and avoid driving through large puddles and
deep-standing or flowing water.
{WARNING:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause
pulling to one side. You could lose control of the
vehicle.
After driving through a large puddle of water or a
car/vehicle wash, lightly apply the brake pedal until
the brakes work normally.
Flowing or rushing water creates strong forces.
Driving through flowing water could cause your
vehicle to be carried away. If this happens, you
and other vehicle occupants could drown. Do not
ignore police warnings and be very cautious about
trying to drive through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle’s tires so they 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.
There is no hard and fast rule about hydroplaning. The
best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
•Allow extra following distance.
•Pass with caution.
•Keep windshield wiping equipment in good shape.
•Keep the windshield washer fluid reservoir filled.
•Have good tires with proper tread depth. SeeTires
on page 6-60.
•Turn off cruise control.

To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine off
and close the window most of the way to save heat.
Repeat this until help arrives but only when you
feel really uncomfortable from the cold. Moving about to
keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator
pedal slightly so the engine runs faster than the idle
speed. This keeps the battery charged to restart
the vehicle and to signal for help with the headlamps.
Do this as little as possible to save fuel.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
Slowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow. See
Rocking Your Vehicle to Get It Out on page 5-19.If the vehicle has a traction system, it can often help to
free a stuck vehicle. Refer to the vehicle’s traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{WARNING:
If the vehicle’s tires spin at high speed, they can
explode, and you or others could be injured.
The vehicle can overheat, causing an engine
compartment fire or other damage. Spin the
wheels as little as possible and avoid going above
55 km/h (35 mph) as shown on the speedometer.
For information about using tire chains on the vehicle,
seeTire Chains on page 6-84.
