Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

Keep the air path under the front seats clear of
objects. This helps circulate air throughout
your vehicle.
Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment filter. The filter removes certain
contaminants from the air, including pollen and dust
particles. Reductions in airflow, which may occur more
quickly in dusty areas, indicate that the filter needs to
be replaced early.
The filter should be replaced as part of routine
scheduled maintenance. See ªPassenger Compartment
Air Filterº in the Index for more information on
replacement. See ªMaintenance Scheduleº in the Index
for replacement intervals.
Your vehicle will not be damaged if you choose not to
replace the filter once the old one is removed.HVAC Steering Wheel Controls
(If Equipped)
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. See ªAudio
Steering Wheel Controlsº in
the Index.
~TEMP! (Temperature): Press the up arrow on the
control to increase the temperature and the down arrow
to decrease temperature manually.

3-11 Climate Control Personalization
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings. These settings
include the set temperatures for the driver and front
passenger, the air conditioning, the airflow mode and
the fan speed. (This feature does not recall recirculation
or defrost).
Each driver (1 or 2) has a corresponding number located
on the back of the remote keyless entry transmitter.
Settings recalled by the system can be determined by
which transmitter is used to unlock the vehicle. When
the button with the unlock symbol is pressed, the
settings will be automatically recalled for that driver.
The settings can also be recalled when the key is placed
in the ignition. If the settings are recalled this way, the
system will recall the settings of the last driver to use the
vehicle. If these are not the correct settings for you,
press the button with the unlock symbol on remote
keyless entry transmitter that was used when you saved
your settings.The settings can also be recalled by briefly pressing the
corresponding memory button (1 or 2) located on the
driver's door panel.
Further programming for recalling climate control
personalization settings can be done using the DIC.
You can select or not select the following:

Automatic recall of the climate control settings when
the vehicle is unlocked with the remote keyless entry
transmitter, or

Automatic recall of the climate control settings when
a key is placed in the ignition.
For more programming information, see ªMemory and
Personalization Featuresº in the Index.

The cassette tape is tight and the cassette player
cannot turn the hubs of the tape. Hold the cassette
tape with the open end down and try turning the right
hub counterclockwise with a pencil. Flip the tape
over and repeat. If the hubs do not turn easily, your
cassette tape may be damaged and should not be
used in the player. Try a new tape to be sure your
player is working properly.

The cassette tape is broken. (Check to see if your
tape is broken. Try a new tape.)

Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in your
vehicle: Buckle up. See ªSafety Beltsº in the Index.Defensive driving really means ªbe ready for anything.º
On city streets, rural roads or freeways, it means
ªalways expect the unexpected.º
Assume that pedestrians or other drivers are going to be
careless and make mistakes. Anticipate what they might
do. Be ready for their mistakes.
Rear
-end collisions are about the most preventable of
accidents. Yet they are common. Allow enough
following distance. It's the best defensive driving
maneuver, in both city and rural driving. You never
know when the vehicle in front of you is going to brake
or turn suddenly.
Defensive driving requires that a driver concentrate on
the driving task. Anything that distracts from the
driving task
-- such as concentrating on a cellular
telephone call, reading, or reaching for something on the
floor
-- makes proper defensive driving more difficult
and can even cause a collision, with resulting injury.
Ask a passenger to help do things like this, or pull
off the road in a safe place to do them yourself.
These simple defensive driving techniques could
save your life.

4-6
Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator. All three systems have to do their work
at the places where the tires meet the road.
Sometimes, as when you're driving on snow or ice, it's
easy to ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle. Also see ªTraction Control Systemº in
the Index.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That's perception time. Then you have to bring up your
foot and do it. That's reaction time.
Average reaction time is about 3/4 of a second. But
that's 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 3/4 of a second, a vehicle
moving at 60 mph (100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an emergency, so
keeping enough space between your vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it's pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.

4-7
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. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
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, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº in
the Index.

4-9
Remember: Anti-lock doesn't change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you won't have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti
-lock brakes.
Using Anti
-Lock
Don't pump the brakes. Just hold the brake pedal down
firmly and let anti
-lock work for you. You may hear the
anti
-lock pump or motor operate, and feel the brake
pedal pulsate, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery road
conditions. The system operates only if it senses that
one or both of the front wheels are spinning or
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine power
to limit wheel spin.
The TRACTION ENGAGED message will display on
the Driver Information Center when the traction control
system is limiting wheel spin. See ªDriver Information
Center Messagesº in the Index. You may feel or hear
the system working, but this is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the cruise control. See ªCruise Controlº in
the Index.

United States Canada
This warning light will come on to let you know if
there's a problem with your traction control system.
See ªTraction Control System Warning Lightº in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is
required. See ªRocking Your Vehicleº in the Index.
To turn the system off, press
the TRAC ON/OFF button
located on the center
console. (For vehicles with
a column shift lever, the
button is located at the end
of the shift lever.)
The TRACTION OFF message will display on the
Driver Information Center. If the system is limiting
wheel spin when you press the button, the TRACTION
OFF message will display
-- but the system won't turn
off right away. It will wait until there's no longer a
current need to limit wheel spin.
You can turn the system back on at any time by pressing
the button again. The TRACTION READY message
should display briefly on the Driver Information Center.
