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 329and
StabiliTrak
®System on page 331.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modi cations on page 363.
Braking
SeeBrake System Warning Light on page 192.
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 the brakes; the weight of the vehicle;
and the amount of brake force applied.
326
Page 327 of 512

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. The brakes may not have
time to cool between hard stops. The 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 vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the 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 363.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 193.

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 194. 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 354andIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 353for 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. SeeDIC Warnings
and Messages on page 206for more information.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modi cations on page 363for more information.
