It is important to note that the moisture-sensing delay
wiping feature can be overridden at any time by
manually turning the wiper band to LO or HI speed.
If the windshield on your vehicle ever needs
replacement, make sure that the new windshield is
moisture
-sensing delay compatible.
Windshield Washer
At the top of the multifunction lever there is a paddle
with the word PUSH on it. For ªprogrammedº
operation, press and release the paddle. The washer will
provide a measured amount of fluid to the windshield
and the wiper will either stop or return to your original
wiping speed. For ªdemandº operation, press and hold
the paddle for at least two seconds. Release the paddle
when you have enough fluid and the wipers will either
stop or return to your original wiping speed.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
If your vehicle is equipped with a DIC, a WINDSHIELD
WASHER FLUID LOW message will appear on the
display when the vehicle is low on washer fluid.
Cruise Control
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot on
the accelerator. This can really help on long trips.
Cruise control does not work at speeds below about
25 mph (40 km/h).
When you apply your brakes, the cruise control shuts off.
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.

If your vehicle is in cruise control when the optional
traction control system begins to limit wheel spin, the
cruise control will automatically disengage. (See
ªTraction Control Systemº in the Index.) When road
conditions allow you to safely use it again, you may turn
the cruise control back on.
Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use it.
1. Move the cruise control
switch to ON.
2. Get up to the speed you want.
3. Push in the SET button at the end of the turn signal
lever and release it. The CRUISE light on the
instrument panel will come on.
4. Take your foot off the accelerator pedal.

2-76 Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when you start
your engine and may stay
on for several seconds.
That's normal.
If the light stays on and the chime sounds, turn the ignition
to OFF. Or, if the light comes on and the chime sounds
when you're driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the light still stays on and the chime sounds, or
the light comes on again while you're driving, your
vehicle needs service. If the regular brake system warning
light isn't on, you still have brakes, but you don't have
anti
-lock brakes. If the regular brake system warning light
is also on, you don't have anti
-lock brakes and there's a
problem with your regular brakes. See ªBrake System
Warning Lightº earlier in this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Traction Control System Warning
Light (Option)
This warning light should
come on briefly as you start
the engine.
If the warning light doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem. If it
stays on, or comes on when you're driving, there may be
a problem with your traction control system and your
vehicle may need service. When this warning light is on,
the system will not limit wheel spin. Adjust your
driving accordingly.

The traction control system warning light may come on
for the following reasons:

If you turn the system off by pressing the button
located on the end of the shift lever, the warning
light will come on and stay on. To turn the system
back on, press the button again. The warning light
should go off. (See ªTraction Control Systemº in the
Index for more information.)

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off, the warning light will come on and the
chime will sound.

If the traction control system is affected by an
engine
-related problem, the system will turn off,
the warning light will come on and the chime
will sound.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
This gage measures the
temperature of your engine.
If the pointer moves into the
red area, your engine is too
hot. A temperature indicator
light will turn on and a
chime will sound.
If you have been operating your vehicle under normal
driving conditions, and the temperature indicator light
turns on, you should pull off the road, stop your vehicle
and turn off the engine as soon as possible.
The section ªProblems on the Road,º in this manual
explains what to do. See ªEngine Overheatingº in
the Index.

Tire Pressure Status: Press the GAGE INFO button
until TIRE PRESSURE appears in the display. TIRE
PRESSURE NORMAL is displayed when the Check
Tire Pressure System believes your vehicle's tire
pressures are normal. If a potential tire pressure problem
is detected, the display will show TIRE PRESSURE
LOW: CHECK TIRES. If you see the TIRE
PRESSURE LOW: CHECK TIRES message, you
should stop as soon as you can and check all your tires
for damage. (If a tire is flat, see ªIf a Tire Goes Flatº in
the Index.) Also check the tire pressure in all four tires
as soon as you can. See ªInflation
- Tire Pressureº and
ªCheck Tire Pressure Systemº in the Index.
There are times when you will have to reset (calibrate)
the Check Tire Pressure System. See ªCheck Tire
Pressure Systemº in the Index.
DIC Warnings and Messages
Other messages or warnings may appear in the DIC
display such as:

DIC Display and
Personal Choice Programming
The DIC is used to program the personal choices of two
drivers. The drivers are recognized as DRIVER #1 and
DRIVER #2. The DIC will identify a person as UNKNOWN
DRIVER if they are neither DRIVER #1 nor DRIVER #2.
You will let the DIC know which driver you are by using
your remote keyless entry transmitter or by pressing one of
the MEMORY buttons located on the driver's door. Each
remote keyless entry transmitter was pre
-programmed to
belong to DRIVER #1 or DRIVER #2. Each transmitter may
be programmed differently for each driver.
After you press UNLOCK on your transmitter and the
ignition is in RUN, the DIC will automatically display
the identified driver number. The vehicle will recall the
personal choice settings that were last made to
correspond to your transmitter, including your radio and
comfort control settings. See ªComfort Controls,
Personal Choiceº in the Index.

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 a
slight brake pedal pulsation or notice some noise, but
this is normal.
Traction Control System (If Equipped)
Your vehicle may have 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.
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.)
This light should come on
briefly when you start the
engine. If it stays on or
comes on while you are
driving, 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, ice or snow. See ªRocking Your Vehicleº
in the Index.)

To turn the system off, press the button located at the
end of the shift lever.
The traction control system warning light will come on
and stay on. If the system is limiting wheel spin when
you press the button, the warning light will come
on
-- 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 control system warning
light should go off.
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.
Magnasteer
(If Equipped)
Your vehicle may be equipped with GM Magnasteer, a
steering system that continuously adjusts the effort you
feel when steering at all vehicle speeds. It provides ease
when parking yet a firm, solid feel at highway speeds.
Your steering can be adjusted for an easier or more firm
setting. See your dealer for information.

4-11 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. Refer to ªTraction Controlº in the Index.
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.

Loss of Control
Let's review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don't have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don't give up. Keep trying to
steer and constantly seek an escape route or area
of less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking
reasonable care suited to existing conditions, and
by not ªoverdrivingº those conditions. But skids
are always possible.
The three types of skids correspond to your vehicle's
three control systems. In the braking skid, your wheels
aren't rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid, too
much throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.
If you have the traction control system, remember: It
helps avoid only the acceleration skid.If you do not have traction control, or if the system is
off, then an acceleration skid is also best handled by
easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you'll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting to a lower
gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your
vehicle is skidding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a ªmirrored surfaceº
-- and slow
down when you have any doubt.
Remember: Any anti
-lock brake system (ABS) helps
avoid only the braking skid.
