Automatic Transmission Operation
There are several different
positions for your shift
lever. Push in the button
on top of the shift lever
when shifting into position.
PARK (P):The engine can be started in this position.
This position prevents the rear wheels from turning
and so should be selected, together with the parking
brake, when leaving the vehicle.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake ®rmly set. Your vehicle can roll.
CAUTION: (Continued)
CAUTION: (Continued)
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). See
Shifting Into Park (P) (Automatic
Transmission) on page 2-24
. If you are pulling
a trailer, see
Towing a Trailer on page 4-34.
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 have your foot
on the regular brakes before you can shift from
PARK (P) when the ignition key is in ON. The vehicle
will not shift from PARK (P) if the button is pressed
before the brake is applied. If you cannot shift out of
PARK (P), ease pressure on the shift lever, push
the shift lever all the way into PARK (P), and release
the shift lever button as you maintain brake application.
Then press the shift lever button and move the shift
lever into the desired gear. See
Shifting Out of Park (P)
(Automatic Transmission) on page 2-26.

REVERSE (R):Use this gear to back up.
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.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
see
If Your Vehicle is Stuck in Sand, Mud, Ice or Snow
on page 4-28.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. 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.
DRIVE (D):This is the most effective position for normal
or freeway driving. This position gives maximum fuel
efficiency, as the transmission can choose the
appropriate gear (1 through 4) for the existing load and
driving conditions.
THIRD (3):This position is also used for normal driving.
However, it offers more power and lower fuel economy
than DRIVE (D). Here are some times you might choose
THIRD (3) instead of DRIVE (D):
·When driving on hilly, winding roads.
·When towing a trailer, so there is less shifting
between gears.
·When going down a steep hill.
SECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you
would also want to use your brakes off and on.

Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift lock
control system. You must fully apply your regular brakes
before you can press the button on the shift lever to
shift from PARK (P) while the ignition is ON. See
Automatic Transmission Operation on page 2-19.
If you cannot shift out of PARK (P), ease pressure on
the shift lever by pushing it all the way into PARK (P)
while keeping the brake pedal down. Release the shift
lever button. Then move the shift lever out of
PARK (P), being sure to press the shift lever button.
Shift Lock Release
If you ever hold the brake pedal down but still cannot
shift out of PARK (P), try this:
1. Turn the ignition to LOCK to remove the key.
2. Remove the front console rubber insert, located in
front of the shift lever, by lifting upwards.
3. Remove the screw slightly to the right of the front
center.
4. Open the console storage compartment and pry the
console cover assembly from the console. The
cover is attached in six places.
5. Insert a tool into the opening in front of the shift
lever and move the yellow release lever forward.
6. Press the button on the shift lever to move lever out
of park.
7. Replace the console cap.
8. Have the vehicle ®xed as soon as possible.

Brake System Warning Light
This light will come on
when the ignition is turned
to ON and when the
parking brake is applied, if
it does not, have it ®xed so
it will be ready to warn you
if there is a problem.
If this light comes on and the Brake message appears
on the trip computer display while driving and the
parking brake is released, a fault with the brakes is
indicated. You should immediately stop the car on the
side of the road as carefully as possible. Do not proceed
until satis®ed that braking is possible or that the
cause of the problem has been ®xed.
A warning will chime if you attempt to drive off without
releasing the parking brake.
The Brake message will remain until the MODE button
on the trip computer is pressed, but the symbol will
remain until the problem is ®xed. See

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. See
Traction Control
System (TCS) on page 4-9.
Adding non-GM accessories can affect your vehicle's
performance. See
Accessories and Modi®cations
on page 5-3.
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 Ð heavy acceleration followed by heavy
braking Ð 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. See
Accessories and Modi®cations
on page 5-3.
Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When you start your engine and 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
a little. This is normal.
If there is a problem with
ABS, this warning light
will stay on. See
Anti-Lock Brake System
Warning Light on
page 3-27
.

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.
ABS 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: ABS 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 ABS.

Using ABS
Do not pump the brakes. Just hold the brake pedal
down ®rmly 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 ABS, 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 (TCS)
Your vehicle has a Traction Control System (TCS) 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 rear wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power and applies the
brakes, as necessary.Traction control helps you to keep control of the
vehicle and reminds you to match your speed to the
road conditions.
You may feel or hear the system working, but this is
normal. The TCS is automatically turned on whenever
the ignition is turned from off to on. A Low Traction
message is displayed on the trip computer, indicating
traction control is limiting wheel spin, until the MODE
button on the trip computer is pressed. The message
then goes back to the original trip computer display with
a small low traction symbol on the left. The symbol
will remain as long as the low traction situation exists.
To limit wheel spin, especially in slippery road
conditions, you should always leave the TCS on. But
you can turn the system off if you prefer.

Suppose you are steering through a sharp curve.
Then you suddenly apply the brakes. Both control
systems Ð steering and braking Ð have to do their work
where the tires meet the road. Unless you have
four-wheel anti-lock brakes, adding the hard braking can
demand too much of those places. You can lose control.
The same thing can happen if you are steering through
a sharp curve and you suddenly accelerate. Those two
control systems Ð steering and acceleration Ð can
overwhelm those places where the tires meet the road
and make you lose control. See
Traction Control System
(TCS) on page 4-9.
What should you do if this ever happens? Ease up on
the brake or 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 will 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.Adding non-GM accessories can affect your vehicle's
performance. See
Accessories and Modi®cations
on page 5-3.
Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and ®nd
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 Ð if you can stop
in time. But sometimes you cannot; there is not room.
That is the time for evasive action Ð steering around
the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes Ð but, unless you
have anti-lock brakes, not enough to lock your wheels.
See
Braking on page 4-6. 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.
