Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transmission
shift lock control system. You must fully apply your
regular brakes before you can shift from PARK (P) when
the ignition key is in RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever. Push the shift
lever all the way into PARK (P) while pressing the button
on the shift lever as you maintain brake application. Then
move the shift lever into the gear you wish. SeeShifting
Out of Park (P) (Automatic Transmission) on page 2-26.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
REVERSE (R):Use this gear to back up.
At low vehicle speeds, you can also use REVERSE (R) to
rock your vehicle back and forth to get out of snow, ice or
sand without damaging your transmission. SeeIf Your
Vehicle is Stuck in Sand, Mud, Ice or Snow on page 4-28
for additional information.NEUTRAL (N):In this position, the engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. You can also
use NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be covered
by your warranty. Be sure the engine is not running
at high speed when shifting your vehicle.

AUTOMATIC OVERDRIVE (D):This position is for
normal driving. If you need more power for passing,
and you are:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transmission will shift down to a lower gear and
have more power.
Notice:Driving your vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transmission. Have your
vehicle serviced right away. You can drive in
SECOND (2) when you are driving less than 35 mph
(55 km/h) and AUTOMATIC OVERDRIVE (D) for
higher speeds until then.
FOURTH (4):This position is also used for normal
driving. However, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D).
Here are examples for using FOURTH (4) instead of
AUTOMATIC OVERDRIVE (D).
When driving on hilly, winding roads.
When going down a steep hill.INTERMEDIATE (I):This position is also used for
normal driving. However, it offers braking from
the engine for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If repetitive shifts occur between third and fourth
gears on steep uphills, this position can be used to
prevent repetitive shifting. Fuel economy will be lower
than AUTOMATIC OVERDRIVE (D). A time you
might choose INTERMEDIATE (I) instead of
AUTOMATIC OVERDRIVE (D) is when driving on hilly
and winding roads.
LOW (L):This position gives you even more power but
lower fuel economy than INTERMEDIATE (I). You can
use it on very steep hills, or in deep snow or mud. If the
shift lever is put in LOW (L), the transmission will not shift
into Low gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.

Setting Cruise Control
{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.
The cruise control buttons
are located on the steering
wheel.
J(On/Off):Press this button to turn the cruise
control system on and off.RES+ (Resume):Press this button to resume a set
speed and to accelerate the speed.
SET−(Set):Press this button to set a speed and to
decrease the speed.
To set a speed do the following:
1. Press the on/off button to turn cruise control on.
The indicator light on the button will come on.
2. Get to the speed you want.
3. Press the SET−control button and release it. The
CRUISE ENGAGED message will appear on the
Driver Information Center (DIC) to show the system
is engaged.
4. Take your foot off the accelerator pedal.
When you apply the brakes or clutch, the cruise control
will shut off.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. To return to your
previously set speed, you do not need to go through the
set process again. Once you’re going about 25 mph
(40 km/h) or more, you can press the RES+ button brie y.
This will take you back up to your previously chosen
speed and stay there.
3-11
If the light comes on while you are driving, pull off the
road and stop carefully. Make sure the parking brake is
fully released. 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
If your vehicle is equipped
with the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes 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 after driving at a speed of at least 13 mph
(20 kph), or comes on again while you are driving, your
vehicle needs service. If the regular brake system
warning light is not on, you still have brakes, but you do
not have anti-lock brakes. If the regular brake system
warning light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-27.
The anti-lock brake system warning light will come on
brie y 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.
3-28
The body takes about an hour to rid itself of the alcohol
in one drink. No amount of coffee or number of cold
showers will speed that up. “I will be careful” is not the
right answer. What if there is an emergency, a need
to take sudden action, as when a child darts into
the street? A person with even a moderate BAC might
not be able to react quickly enough to avoid the
collision.
There is something else about drinking and driving that
many people do not know. 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.
{CAUTION:
Drinking and then driving is very dangerous.
Your re exes, perceptions, attentiveness, and
judgment can be affected by even a small
amount of alcohol. You can have a serious — or
even fatal — collision if you drive after drinking.
Please do not drink and drive or ride with a
driver who has been drinking. Ride home in a
cab; or if you are with a group, designate a
driver who will not drink.
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.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3.
4-5
Braking
SeeBrake System Warning Light on page 3-27.
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 your 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. 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 are driving, brake
normally but do not 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.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3.

Anti-Lock Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock
brakes, this warning light
on the instrument panel will
come on brie y when
you start your vehicle.
When you start your engine, or when you 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 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 wheel.
4-7
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.Remember: Anti-lock does not 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 will not 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
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may feel
a slight brake pedal pulsation or notice some noise,
but this is normal.
