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, cruise control is turned off.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not 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 excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.
If your vehicle is in cruise control when the traction
control system (if equipped) begins to limit wheel spin,
the cruise control will automatically disengage.SeeTraction Control System (TCS) on page 4-9. When
road conditions allow you to safely use it again, you
may turn the cruise control back on.
The cruise control buttons
are located on left side of
the steering wheel.
T(On/Off):Press this button to turn cruise control on
and off. The indicator will be lit when cruise control is on.
+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
SET–:Press this button to set the speed or make the
vehicle decelerate.
[(Cancel):Press this button to cancel cruise control.

Setting Cruise Control
Cruise control will not work if your parking brake is set,
or if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
will come on after the cruise control has been set to
the desired speed.
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Press the cruise control on/off button.
2. Get up to the speed you want.
3. Press and release the SET– button located on the
steering wheel.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This shuts off the
cruise control. But you do not need to reset it.
Once you are driving about 25 mph (40 km/h) or more,
press the +RES button on your steering wheel. The
vehicle will go back to your chosen speed and
stay there.
Increasing Speed While Using
Cruise Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until you reach your new desired speed,
then release it.
To increase vehicle speed in small increments,
press the +RES button.
3-11

Reducing Speed While Using
Cruise Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the steering
wheel until you reach the lower speed you want,
then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel briey.
Each time you do this, you will go about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase vehicle speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers nd this to be too much trouble and do not
use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[(cancel) button on the steering wheel.
Press theT(on/off) button on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased by
turning off the cruise control or the ignition, or by
pressing the cancel button.
Exterior Lamps
The exterior lamps control
is located on the
instrument panel to the left
of the steering wheel.

Charging System Light
The charging system light
will come on briey when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have
a problem with the charging system. It could indicate
that you have problems with a generator drive belt,
or another electrical problem. Have it checked
right away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as the
radio and air conditioner.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to RUN. If it does not come on then, have it
xed so it will be ready to warn you if there is a problem.

When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does
not release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push, or the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-34.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed
for service.
Anti-Lock Brake System
Warning Light
Your vehicle may have an
Anti-Lock Brake System
(ABS) warning light.
It should come on for a few seconds when you turn the
ignition key to RUN.
If the ABS warning light stays on longer than normal
after you have started your engine, turn the ignition off
or, if the light comes on and stays on when you are
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, or comes on again while you are
driving, the ABS needs service and you do not have
anti-lock brakes.
The ABS warning light should come on briey when you
turn the ignition key to RUN. This is normal. If the
light does not come on then, have it xed so it will be
ready to warn you if there is a problem.

SERVICE BRAKE SYSTEM
This message will display when service is required on
the brake system. Have the brake system serviced
by your GM dealer as soon as possible. The brake
system warning light will also appear on the instrument
panel cluster when this message appears on the
DIC. SeeBrake System Warning Light on page 3-30.
SERVICE POWER STEERING
This message will display when a problem is detected
with the power steering system. When this message
is displayed, you may notice that the effort required to
steer the vehicle increases or feels heavier, but you will
still be able to steer the vehicle. Have your vehicle
serviced by your GM dealer immediately.
SERVICE THEFT SYSTEM
This message will display when there is a problem
with the theft-deterrent system programmed in the key.
A fault has been detected in the system which means
that the system is disabled and it is not protecting
the vehicle. The vehicle usually restarts; however,
you may want to take the vehicle to your GM dealer
before turning off the engine. SeePASS-Key
®III+
Operation on page 2-19for more information.
SERVICE TIRE MONITOR SYSTEM
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message will display if a part on the system
is not working properly. If you drive your vehicle while
any of the four sensors are missing or inoperable,
the warning will come on in about 10 minutes. A sensor
would be missing, for example, if you put different
wheels on your vehicle without transferring the sensors.
If the warning comes on and stays on, there may be
a problem with the TPM. See your GM dealer.
SERVICE TRACTION CONTROL
If your vehicle has the traction control system, this
message will display when the system is not functioning
properly. A warning light will also appear on the
instrument panel cluster. SeeTraction Control System
(TCS) Warning Light on page 3-32. SeeTraction Control
System (TCS) on page 4-9for more information.

Keeping your mind on the drive is important for safe
driving. Here are some ways in which you can help
avoid distraction while driving.
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 5-3.
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 2-22for more
information.

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 are driving on snow or ice,
it is easy to ask more of those control systems than the
tires and road can provide. That means you can lose
control of your vehicle. SeeTraction Control System
(TCS) on page 4-9.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3.
Braking
SeeBrake System Warning Light on page 3-30.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That 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 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 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 may not have time to cool
between hard stops. The 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 vehicle’s engine ever stops while you are driving,
brake normally but do not pump the brakes. If you do,
the pedal may get harder to push down. If the 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.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3.

Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake System
(ABS), an advanced electronic braking system that will
help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel
cluster will come on briey
when you start your
vehicle.
When you start your engine, or when you begin to drive
away, ABS 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
or pulses a little. This is normal.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 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.
