Braking
SeeBrake System Warning Light on page 3-47.
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.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 might 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 could 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 can take longer to stop and
the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 6-3.

Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When you start the engine and begin to drive away,
ABS will check itself. You might hear a momentary
motor or clicking noise while this test is going on, and
you might even notice that the brake pedal moves
a little. This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAntilock Brake
System (ABS) Warning
Light on page 3-48.
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 the 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 to each wheel, as
required, faster than any driver could. This can help
you steer around the obstacle while braking hard.
As you brake, the 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 the 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 antilock work for you. You might hear
a motor or clicking noise and feel the brake pedal
move a little during a stop, but this is normal.
5-5

Braking in Emergencies
With ABS, you can steer and brake at the same time.
In many emergencies, steering can help more than even
the very best braking.
Brake Assist
This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle speed
in emergency driving conditions. This feature uses the
stability system hydraulic brake control module to
supplement the power brake system under conditions
where the driver has quickly and forcefully applied
the brake pedal in an attempt to quickly stop or slow
down the vehicle. The stability system hydraulic
brake control module increases brake pressure at each
corner of the vehicle until the ABS activates. Minor
brake pedal pulsations or pedal movement during this
time is normal and the driver should continue to
apply the brake pedal as the driving situation dictates
The Brake Assist feature will automatically disengage
when the brake pedal is released or brake pedal
pressure is quickly decreased.
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.
The Traction Control
System (TCS)/StabiliTrak
light is located on the
instrument panel.
STABILITRAK ACTIVE comes on the Driver Information
Center (DIC) when the system is working. SeeDIC
Warnings and Messages on page 3-60for more
information. The system may be heard or felt while it is
working. This is normal.
The TCS/StabiliTrak light comes on the instrument panel,
a chime will sound, and SERVICE STABILITRAK comes
on the DIC if there is a problem with the system.
5-6

When this light and SERVICE STABILITRAK comes on,
the system is not operational and needs to be serviced.
Adjust your driving accordingly.
The system comes on automatically whenever the
vehicle is started. To help maintain directional control
of the vehicle, the system should always be left on.
The system can be turned off if needed. If the StabiliTrak
system is turned off, the Traction Control System will
also be turned off. Adjust your driving accordingly.
The Traction Control
button is located on
the console.To turn the system off, press and hold the TCS/
StabiliTrak button until the light comes on the instrument
panel and STABILITRAK OFF comes on the DIC.
The system can be turned back on at any time by
pressing the button. The TCS/StabiliTrak light turns off
and STABILITRAK ON briey comes on the DIC.
If the Tire Pressure Monitor (TPM) system detects a at
tire and FLAT TIRE comes on the DIC, or if the TPM
system is not working and SERVICE TIRE MONITOR
comes on the DIC, StabiliTrak can be affected in
the following ways:
StabiliTrak cannot be turned off by the driver.
If StabiliTrak is off, it will be turned on automatically.
Performance Mode is unavailable — XLR-V only.

Performance Mode — XLR-V Only
Notice:When traction control is turned off, or
Performance Mode is active, it is possible to lose
traction. If a shift is attempted with the rear wheels
spinning with a loss of traction, it is possible to
cause damage to the transmission. Do not attempt to
shift when the rear wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See the warranty book for additional
information.
For vehicles with this feature, the Performance Mode
can be selected by pressing the TCS/StabiliTrak button
on the console two times quickly. PERFORMANCE
MODE comes on the DIC. Performance Mode allows the
driver to have full control of the rear wheels while the
StabiliTrak System helps maintain directional control of
the vehicle by applying the brakes as necessary.
The TCS/StabiliTrak light will not be on. The TCS will
not be operating. Adjust your driving accordingly.
When the TCS/StabiliTrak button is pressed again, the
StabiliTrak and Traction Control Systems will be on.
The TRAC/STABILITRAK ON message will be displayed
briey in the DIC and a chime will be heard.
Traction Control System (TCS)
The vehicle has a traction control system 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 works the rear brakes and reduces engine
power to limit wheel spin.
The TRAC SYSTEM ACTIVE message will display on
the Driver Information Center (DIC) when the traction
control system is limiting wheel spin. SeeDIC Warnings
and Messages on page 3-60. The system may be
heard or felt while it is working, but this is normal.
If cruise control is being used when the traction control
system begins to limit wheel spin, the cruise control
will automatically disengage. Cruise control may be
reengaged when road conditions allow. SeeAdaptive
Cruise Control on page 3-14orCruise Control on
page 3-11for more information.
5-8

This warning light comes
on if there is a problem
with the traction control
system.
SeeStabiliTrak
®/Traction Control System (TCS) Warning
Light on page 3-48. 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 the vehicle is started. To limit wheel spin,
especially in slippery road conditions, the system should
always be left on but can be turned off if needed. It may
be necessary to turn the system off if the vehicle is stuck
in sand, mud or snow and rocking the vehicle is required.
SeeRocking Your Vehicle to Get It Out on page 5-20and
If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 5-20for more information.To turn the system off,
press 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 the
button is pressed, 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.
The system can be turned back on at any time by
pressing the button again. The TRACTION SYSTEM ON
message should display briey on the Driver Information
Center. SeeDIC Warnings and Messages on page 3-60
for more information.
Adding non-GM accessories can affect the vehicle’s
performance. SeeAccessories and Modifications
on page 6-3for more information.
