SHIFT TO PARK:This message indicates that the
vehicle is not in PARK (P) when the engine is being
turned off. The vehicle will be in accessory mode. Once
the shifter is moved to PARK (P), the vehicle will turn off.
STABILITRAK ACTIVE:You may see the
STABILITRAK ACTIVE message on the DIC. It means
that an advanced, computer-controlled system has
come on to help your vehicle continue to go in
the direction in which you are steering. This stability
enhancement system activates when the computer
senses that your vehicle is just starting to spin, as it
might if you hit a patch of ice or other slippery spot
on the road. When the system is on, you may hear
a noise or feel a vibration in the brake pedal.
This is normal.
When the STABILITRAK ACTIVE message is on, you
should continue to steer in the direction you want to go.
The system is designed to help you in bad weather
or other difficult driving situations by making the
most of whatever road conditions will permit. If the
STABILITRAK ACTIVE message comes on, you will
know that something has caused your vehicle to start to
spin, so you should consider slowing down. A single
chime will also sound when this message is displayed.
STABILITRAK READY:If this message appears
and a chime sounds, the system has completed the
functional check of the StabiliTrak
®System.STABILITRAK WARMING:When you rst start your
vehicle and drive away, especially during cold winter
weather, the STABILITRAK WARMING message may
be displayed in the DIC along with a chime and the
traction control warning light. This is normal. You can
acknowledge this message by pressing the RESET
button. The StabiliTrak
®performance is affected until the
STABILITRAK READY message is displayed in the
DIC, which can take up to 15 minutes.
SVC (Service) TIRE MONITOR:If this message comes
on, a part on the Tire Pressure Monitor (TPM) 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 approximately 10 minutes. If all four sensors
are missing, the warning will come on in approximately
15 to 20 minutes. All the sensors 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.
TOOCOLDTOMOVETOP:This message will display
when the retractable hardtop button is pressed and the
hardtop pump motor temperature is below−4°F (−20°C).
Wait for the hardtop pump motor to warm up before using
the retractable hardtop.

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 5-9andStabiliTrak
®System on
page 5-11.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 6-3.
Braking
SeeBrake System Warning Light on page 3-54.
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.
5-6
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 6-3.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. SeeAnti-Lock
Brake System Warning
Light on page 3-55.
5-7
This warning light will
come on to let you know
if there is a problem
with your traction
control system.
SeeTraction Control System (TCS) Warning Light on
page 3-56. 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
or snow and rocking the vehicle is required. SeeRocking
Your Vehicle to Get It Out on page 5-32andIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 5-32
for more information.To turn the system off,
press the front part of
the traction control button
located on the center
console.
The TRACTION SYSTEM-OFF message will display on
the DIC and the traction control system warning light
will come on. If the system is limiting wheel spin when
you press the button, the TRACTION SYSTEM-OFF
message will display — but the system will not turn off
right away. It will wait until there is 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 SYSTEM-ON message
should display brie y on the Driver Information Center.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 6-3for more information.

Magnetic Ride Control
Magnetic Ride Control automatically adjusts the ride
of your vehicle. Automatic ride control is achieved
through a computer used to control and monitor the
suspension system. The controller receives input
from various sensors to determine the proper system
response. If the controller detects a problem within
the system, the DIC will display a SERVICE RIDE
CONTROL message. SeeDIC Warnings and Messages
on page 3-67for more information. See your dealer
for service.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It works
like a standard axle most of the time, but when one
of the rear wheels has no traction and the other
does, this feature will allow the wheel with traction
to move the vehicle.
StabiliTrak®System
The StabiliTrak®System is a computer controlled
system that helps the driver maintain directional control
of the vehicle in difficult driving conditions. This is
accomplished by selectively applying any one of the
vehicle’s brakes.
When you rst start your vehicle and begin to drive
away (6 mph (10 km/h)), especially during cold weather,
the message STABILITRAK WARMING may be
displayed in the Driver Information Center (DIC), the
instrument cluster light will be on, and a chime will
sound. This is normal. You can acknowledge this
message by pressing the RESET button. The
StabiliTrak
®System performance is affected until the
message, STABILITRAK READY, is displayed in
the DIC. This can take up to 15 minutes.
The WAIT FOR STABILITRAK message may be
displayed in the DIC after exceeding 19 mph (30 km/h)
for 10 seconds if the steering is not centered.
The system is off until the STABILITRAK ACTIVE
message is displayed.
5-11
The STABILITRAK ACTIVE message will come on
when the system is operating. SeeDIC Warnings
and Messages on page 3-67for more information.
You may also feel or hear the system working.
This is normal.
The instrument cluster
light will come on and a
chime will sound to let
you know if there is
a problem with the system.
The SERVICE STABILITRAK message will also be
displayed. SeeDIC Warnings and Messages on
page 3-67for more information.
When this light and the SERVICE STABILITRAK
message are on, the system is not operational.
Adjust your driving accordingly.The system comes on automatically whenever you start
your vehicle. To help maintain directional control of
the vehicle, you should always leave the system on.
You can turn the system off if you ever need to. If you
turn the STABILITRAK
®System off, the Traction
Control System will also be turned off. Adjust your
driving accordingly.
To turn the system off,
press and hold the
front part of the traction
control button on the
console for ve seconds
with the vehicle stopped.
You can turn the system back on at any time by pressing
the button. The DIC will display the appropriate message
when you push the button, either TRAC/STABILITRAK
ON or TRAC/STABILITRAK OFF.

Here are ways to increase your safety in city driving:
Know the best way to get to where you are
going. Get a city map and plan your trip into
an unknown part of the city just as you would for
a cross-country trip.
Try to use the freeways that rim and crisscross
most large cities. You will save time and energy.
SeeFreeway Driving on page 5-23.
Treat a green light as a warning signal. A traffic
light is there because the corner is busy enough
to need it. When a light turns green, and just before
you start to move, check both ways for vehicles
that have not cleared the intersection or may
be running the red light.
Freeway Driving
Mile for mile, freeways — also called thruways, parkways,
expressways, turnpikes, or superhighways — are the
safest of all roads. But they have their own special rules.
