2-50 Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or misty
conditions. Your parking lamps or low
-beam headlamps
must be on for your fog lamps to work.
The fog lamp button is on the instrument panel near the
exterior lamps control.
Press the button to turn the fog lamps on. Press the
button again to turn them off. A light will glow in the
switch when the fog lamps are on.
The fog lamps will go off whenever your high
-beam
headlamps come on. When the high
-beam headlamps
go off, the fog lamps will come on again.
Interior Lamps
Instrument Panel Brightness Thumbwheel
This feature controls the brightness of the instrument
panel lights.
It is located on the driver's side of your instrument panel
next to the exterior lamps control.
Turn the thumbwheel up to make your instrument
panel lights brighter or down to dim them. Turn the
thumbwheel all the way up to turn on the interior lamps.
Illuminated Entry
Your vehicle is equipped with an illuminated
entry feature.
When any door is opened, the dome lamps will come on
if the DOME OVERRIDE button is in the out position.
If your vehicle is equipped with Remote Keyless Entry
and all the doors are closed, or the front door handles
are lifted and released, the lamps will stay on for a short
period of time and will turn off automatically. If you use
your keyless entry transmitter to unlock the vehicle, the
interior lights will come on for a short time whether or
not the DOME OVERRIDE button is in the out position.

2-51 Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition to help you see
while exiting the vehicle. These lights will stay on for a
short period of time and then will go out, if the DOME
OVERRIDE button is in the out position.
Front Map Lamps (If Equipped)
If your vehicle has front map lamps, they are located
on the inside rearview mirror. They will automatically
come on for approximately 40 seconds when the doors
are unlocked with the keyless entry transmitter (if
equipped) or until the ignition key is turned to RUN
or ACCESSORY. The lamps will also stay on for
approximately 40 seconds after you exit the vehicle,
unless you lock the doors with the keyless entry
transmitter.
You can also turn the lamps on and off by pressing the
switch near each lamp.
Dome Lamps
The dome lamps will come on when you open any door.
You can also turn the dome lamps on by turning the
thumbwheel, located next to the exterior lamps control,
all the way up to the second notch. In this position, the
dome lamps will remain on whether a door is opened or
closed.
You can use the DOME OVERRIDE button, located
below the exterior lamps control, to set the dome lamps
to come on automatically when any door is opened, or to
remain off. To turn the lamps off, press the button in.
With the button in, the dome lamps will remain off when
any door is opened. To return the lamps to automatic
operation, press the button again and return it to the out
position. With the button in this position, the dome
lamps will come on when you open any door. This will
override the illuminated entry feature, unless you use
your keyless entry transmitter (if equipped) to unlock
the vehicle.

2-81 Service Four-Wheel-Drive Warning Light
This light should come on
briefly when you turn on the
ignition, as a check to show
you it is working.
The SERVICE 4WD light comes on to indicate that
there may be a problem with the four
-wheel drive
system and service is required. Malfunctions can be
indicated by the system before any problem is apparent,
which may prevent serious damage to the vehicle. This
system is also designed to assist your service technician
in correctly diagnosing a malfunction.
Check Gages Light
If this light comes on and
stays on while you are
driving, check your coolant
temperature and engine oil
pressure gages to see if they
are in the warning zones.

3-6 Defogging and Defrosting
On cool, humid days, use blend to keep the windshield
and side windows clear.
Use defrost to remove fog or ice from the windshield
quickly in extreme humid or cold conditions. Turn the
temperature knob clockwise and turn the fan control
toward high.
If you have the heated outside mirror feature, you can
use it to defog or defrost your outside mirrors. For more
information, see ªHeated Outside Mirrorsº in the Index.
Ventilation System
Your vehicle's ventilation system supplies outside air to
the inside of your vehicle when it is moving. When the
vehicle is not moving, you can get outside air to flow
through by selecting any mode and any fan speed.
You will find air outlets in the center and on the sides of
your instrument panel.
You can direct the airflow side
-to-side by moving the
thumbwheel located in the center of the vent. The vent
can be tilted up and down also. To control the amount of
airflow through the outlets, move the thumbwheel below
the vent.

Let's say the road is wet and you're driving safely.
Suddenly, an animal jumps out in front of you.
You slam on the brakes and continue braking.
Here's 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.The anti
-lock system can change the brake pressure faster
than any driver could. The computer is programmed to
make the most of available tire and road conditions. This
can help you steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

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 feel the
brakes vibrate, or you may notice some noise, 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.
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
Driving on Curves
It's important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº accidents mentioned on
the news happen on curves. Here's 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's no traction, inertia will keep
the vehicle going in the same direction. If you've ever
tried to steer a vehicle on wet ice, you'll understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle
at which the curve is banked, and your speed. While
you're in a curve, speed is the one factor you
can control.
Suppose you're steering through a sharp curve.
Then you suddenly accelerate. Both control
systems
-- steering and acceleration -- have to do
their work where the tires meet the road. Adding the
sudden acceleration can demand too much of those
places. You can lose control.

4-10
What should you do if this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want it
to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you'll want to go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed so you can ªdriveº through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until you are out of the curve, and then
accelerate gently into the straightaway.Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you. You can
avoid these problems by braking
-- if you can stop in
time. But sometimes you can't; there isn't room.
That's the time for evasive action
-- steering around
the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes. See ªBraking in
Emergenciesº earlier in this section. It is better to
remove as much speed as you can from a possible
collision. Then steer around the problem, to the left or
right depending on the space available.
