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.

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.

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.
