Automatic Transaxle Operation
If your vehicle has an
automatic transaxle, the
shift lever is located on
the console between
the seats.
Your vehicle may also have an electronic shift position
indicator that displays the position of the shift lever.
This indicator is located to the right of the trip odometer
on the instrument panel cluster.
Movement between certain positions requires pushing
the shift lever to the passenger side while shifting.
This prevents you from changing positions unexpectedly
by blocking the straight movement of the shift lever
while the vehicle is moving.
PARK (P):This position locks your front wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.{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.
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). SeeShifting Into Park (P) (Automatic
Transaxle) on page 2-26.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle
shift lock control system. You have to apply your regular
brakes before you can shift from PARK (P) when the
ignition key is in ON. If you cannot shift out of PARK (P)
while holding the brake pedal down, seeShifting Out
of Park (P) (Automatic Transaxle) on page 2-28.

THIRD (3):This position is also used for normal driving,
however, it offers more power and lower fuel economy
than AUTOMATIC OVERDRIVE (D). Here are some
times you might choose THIRD (3) instead of
AUTOMATIC OVERDRIVE (D):
•When driving on hilly, winding roads.
•When going down a steep hill.
SECOND (2):This position gives you more power but
lower fuel economy. 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.
Notice:Do not drive in SECOND (2) at speeds over
65 mph (105 km/h), or you can damage the
transaxle. Use THIRD (3) or AUTOMATIC
OVERDRIVE (D) as much as possible. Do not shift
into SECOND (2) unless you are going slower
than 65 mph (105 km/h) or you can damage your
engine.FIRST (1):This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1), the transaxle will not shift
into first 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 transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes, or parking brake to hold the vehicle
in place.
If there is a malfunction with the automatic transaxle,
the Check Engine Light or the HOLD indicator light will
turn on or flash. SeeMalfunction Indicator Lamp on
page 3-37orHold Mode Light on page 3-36.
Have your vehicle fixed as soon as possible.
2-22

Shifting Out of Park (P)
(Automatic Transaxle)
Your automatic transaxle vehicle has an automatic
transaxle shift lock control system which locks the shift
lever in PARK (P) when the ignition is in LOCK. You
have to fully apply your regular brakes before you can
shift from PARK (P) when the ignition is turned to
ON. SeeAutomatic Transaxle Operation on page 2-20.
If you cannot shift out of PARK (P) while holding the
brake pedal down, try this:
1. Set the parking brake.
2. Turn the ignition off and remove the key.
3. Pry off the cover over the shift-lock release slot
using a small, flat object. The shift-lock release
slot is located at the top of the shift lever.4. Insert the key into the
shift-lock release slot
and press and hold
the key.
5. Shift to NEUTRAL (N).
6. Remove the key from the shift-lock release slot,
insert the key into the ignition and start the
engine.
7. Replace the shift-lock release slot cover.
8. Apply and hold the regular brake fully and release
the parking brake.
9. Shift to the gear you want.
10. Have the system fixed as soon as you can.

Rear Window Wiper/Washer
(Hatchback and Wagon only)
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
Your vehicle has a rear window washer/wiper. Operate
the rear window washer/ wiper system by pushing
the windshield wiper/washer lever away from you.
The wiper operates continuously when the lever is in
the first position. In some vehicle models, the wiper
operates intermittently.
Washer fluid sprays onto the rear window and the wiper
operates continuously when the lever is pushed to
the second position.
Cruise Control
If your vehicle has cruise control, you can maintain a
speed of about 24 mph (39 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 24 mph (39 km/h).
When you apply your brakes, or the clutch pedal if you
have a manual transaxle, the cruise control turns 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.
3-13

The DRL system will make your low-beam headlamps
come on in daylight when the following conditions
are met:
•The ignition is on.
•The exterior lamp band is in OFF or in the parking
lamp position.
•The parking brake is released.
An indicator light will come on when the DRL are on.
SeeDaytime Running Lamps (DRL) Indicator Light
on page 3-41.
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps and instrument panel lights
will not be illuminated unless you have turned the
exterior lamps control to the parking lamp or headlamp
position.
The DRL system will turn off when one of the following
conditions are met:
•The ignition is off.
•The parking brakes are on.
•The high-beam headlamps are on.
•The low-beam headlamps are on.
•The flash-to-pass feature is used.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
If your vehicle has fog lamps, use them for better
visibility in foggy or misty conditions.
The band for the front fog lamps is located in the middle
of the turn signal/multifunction lever. While using the
fog lamps, the ignition must be on as well as the parking
lamps or low-beam headlamps.
Turn the band to ON to turn the fog lamps on. An
indicator light will come on while the fog lamps are on.
SeeFog Lamp Light on page 3-41.
Turn the band to OFF to turn the fog lamps off.
The fog lamps will also turn off while the high-beam
headlamps are turned on. When the high-beam
headlamps are turned off, the fog lamps will turn on
again.
3-17

Anti-Lock Brake System Warning
Light
If your vehicle has an
anti-lock brake system, this
light will come on when
the ignition is turned to ON
and may stay on for
several seconds. That is
normal.
If the light stays on, turn the ignition to LOCK. Or, if the
light comes on, 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, your vehicle needs service. See
your GM dealer. 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 3-34.
The anti-lock brake system warning light will come on
briefly when you turn the ignition to ON. This is normal.
If the light does not come on then, have it fixed so it
will be ready to warn you if there is a problem.
Speed Sensitive Power Steering
(SSPS) Warning Light
If your vehicle has Speed
Sensitive Power Steering,
this warning light will
come on briefly when you
turn the ignition to ON
as a check to show you it
is working.
Then it should go out after a few seconds.
If the warning light does not come on, have it fixed so it
will be able to warn you if there is a problem.
If the warning light stays on, or comes on while you are
driving, the system may not be working. If this
happens, see your GM dealer for service.

At a BAC level of 0.10 percent, the chance of this driver
having a collision is 12 times greater; at a level of
0.15 percent, the chance is 25 times greater!
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 reexes, 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 Modifications
on page 5-3.

Braking
SeeBrake System Warning Light on page 3-34.
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 Modifications
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 will come
on briefly when you
start your vehicle.
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.
4-7

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
firmly and let anti-lock work for you. You may feel a slight
brake pedal pulsation or notice some noise, but this is
normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation that
requires hard braking.
If you have ABS, you can steer and brake at the same
time. However, if you do not have ABS, your first
reaction — to hit the brake pedal hard and hold it
down — may be the wrong thing to do. Your wheels can
stop rolling. Once they do, the vehicle cannot respond to
your steering. Momentum will carry it in whatever
direction it was headed when the wheels stopped rolling.
That could be off the road, into the very thing you were
trying to avoid, or into traffic.
