To release the parking brake, hold
the regular brake pedal down. Pull
the bottom edge of the lever,
located above the parking brake
pedal, with the parking brake
symbol, directly rearward to release
the parking brake.If the ignition is on when the parking
brake is released, the brake system
warning light will go off.
Notice:
Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
If you are towing a trailer and are
parking on any hill, see Driving
Characteristics and Towing Tips on
page 9‑56.
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 pulsation 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.

Ride Control Systems
Traction Control
System (TCS)
The Traction Control System (TCS)
is part of StabiliTrak. TCS limits
wheel slip which is especially useful
in slippery road conditions. The
system operates only if it senses
that any of the wheels are spinning
or beginning to lose traction. When
this happens, TCS applies the
brakes to limit wheel spin and also
reduces engine power. The system
may be heard or felt while it is
working. This is normal and does
not mean there is a problem with
the vehicle.
Notice:If the wheel(s) of one axle
is allowed to spin excessively
while the StabiliTrak
®, ABS, brake
warning lights, and any relevant
DIC messages are displayed, the
transfer case could be damaged.
The repairs would not be covered
by the vehicle warranty. Reduce
engine power and do not spin the wheel(s) excessively while these
lights and messages are
displayed.
TCS can operate on dry roads
under some conditions. When
this happens, the system may be
heard working or a reduction in
acceleration may be noticed. This
is normal and does not mean there
is a problem with the vehicle.
Examples of these conditions
include hard acceleration in a turn,
an abrupt upshift or downshift of the
transmission or driving on rough
roads.
If cruise control is being used when
TCS begins to limit wheel spin, the
cruise control automatically
disengages. The cruise control can
be re-engaged when road
conditions allow. See
Cruise Control
on page 9‑49.
The message TRACTION FAULT
appears in the Driver Information
Center (DIC) when a TCS or
Antilock Brake System (ABS)
problem has been detected and the vehicle needs service. When this
message is on, the system will not
limit wheel spin. Adjust your driving
accordingly. See
Ride Control
System Messages on page 5‑25.
The StabiliTrak/TCS light will flash
on the instrument panel cluster
when the TCS system or StabiliTrak
is both on and activated.
The StabiliTrak/TCS button is
located on the instrument panel.

Black plate (47,1)Chevrolet Colorado Owner Manual - 2011
Driving and Operating 9-47
To turn off TCS, press and release
the StabiliTrak/TCS button. The
StabiliTrak/TCS light comes on in
the instrument panel cluster, and
TRAC OFF comes on the DIC. To
turn TCS back on, press and
release the StabiliTrak/TCS button.
Adding non-dealer/non-retailer
accessories can affect the vehicle's
performance. SeeAccessories and
Modifications on page 10‑4.
StabiliTrak®System
The vehicle has an electronic
stability control system called
StabiliTrak. It is an advanced
computer controlled system that
assists the driver with directional
control of the vehicle in difficult
driving conditions.
StabiliTrak activates when the
computer senses a discrepancy
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one of the vehicle's brakes to assist the
driver with keeping the vehicle on
the intended path.
When the vehicle is started and
begins to move, the system
performs several diagnostic checks
to insure there are no problems.
The system may be heard or felt
while it is working. This is normal
and does not mean there is a
problem with the vehicle. The
system should initialize before the
vehicle reaches 32 km/h (20 mph).
In some cases, it may take
approximately two miles of driving
before the system initializes.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
The cruise control can be
re-engaged when road conditions
allow. See
Cruise Control on
page 9‑49. If there is a problem detected with
StabiliTrak, a SERVICE STAB SYS
message displays on the Driver
Information Center (DIC). See
Ride
Control System Messages on
page 5‑25 for more information.
When this message is displayed,
the system is not working. Adjust
your driving accordingly.
StabiliTrak and Traction Control
(TCS) come on automatically
whenever the vehicle is started and
the systems are reset with each
ignition cycle. However, when the
transfer case is placed in
Four-Wheel-Low mode, StabiliTrak
is automatically disabled. See
Four-Wheel Drive on page 10‑30
for more information. It is
recommended to leave the system
on for normal driving conditions, but
it may be necessary to turn the TCS
portion of the system off if the
vehicle is stuck in sand, mud, ice,
or snow, and it is necessary to
“rock” the vehicle to attempt to free
it. If traction control is turned off,
only the brake-traction control

Black plate (48,1)Chevrolet Colorado Owner Manual - 2011
9-48 Driving and Operating
portion of traction control will work.
The engine speed management will
be disabled. In this mode, engine
power is not reduced automatically
and the drive wheels can spin more
freely. This can cause the
brake-traction control to activate
constantly. SeeIf the Vehicle is
Stuck on page 9‑19.
The StabiliTrak/TCS light will flash
on the instrument panel cluster
when the TCS system or StabiliTrak
is both on and activated.
The StabiliTrak/TCS button is
located on the instrument panel.
To turn off TCS, press and release
the StabiliTrak/TCS button. The
StabiliTrak/TCS light comes on in
the instrument panel cluster, and
TRAC OFF comes on the DIC. To
turn TCS back on, press and
release the StabiliTrak/TCS button.
To turn off TCS and StabiliTrak,
press and hold the StabiliTrak/TCS
button until the TRAC OFF and
STAB SYS OFF messages come on
the DIC and the StabiliTrak/TCS
light comes on the instrument panel.
To turn TCS and StabiliTrak back
on, press and release the
StabiliTrak/TCS button. When the TCS or StabiliTrak system
is turned off, the StabiliTrak/TCS
light and the appropriate TRAC OFF
or STAB SYS OFF message will be
displayed on the DIC. The vehicle
will still have brake-traction control
when TCS or StabiliTrak is off, but
will not be able to use the engine
speed management system. The
StabiliTrak/TCS light flashes when
either system is actively working.
See
Traction Control System (TCS)
on page 9‑46 for more information.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow,
mud, ice, sand or gravel. It works
like a standard axle most of the
time, but when traction is low, this
feature allows the drive wheel with
the most traction to move the
vehicle.

9-50 Driving and Operating
This light on the instrument panel
cluster comes on while the cruise
control is on.
Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied, the cruise control is
disengaged without erasing the set
speed from memory.
Once the vehicle speed reaches
about 40 km/h (25 mph) or more,
move the cruise control lever briefly
from
RtoS. The vehicle returns to
the previous set speed and stays
there.
If the lever is held at resume/
accelerate the vehicle keeps going
faster until the lever is released or the brake is applied. Do not hold the
lever at resume/accelerate, unless
you want the vehicle to go faster.
Increasing Speed While Using
Cruise Control
If the cruise control system is
already activated,
.Use the accelerator pedal to get
to the higher speed. Press
r
T
at the end of the lever, then
release the button and the
accelerator pedal. If the
accelerator pedal is held longer
than 60 seconds, cruise control
will turn off.
.Move the cruise lever fromRto
S. Hold it until the desired
speed is reached, and then
release the lever.
.To increase the vehicle speed in
small amounts, move the lever
briefly to
S. Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated,
.Press and holdr Tuntil the
lower speed desired is reached,
then release it.
.To slow down in small amounts,
briefly press
r T.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previous set cruise control speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or

Black plate (51,1)Chevrolet Colorado Owner Manual - 2011
Driving and Operating 9-51
shift to a lower gear to keep the
vehicle speed down. When the
brakes are applied the cruise control
is disengaged.
Ending Cruise Control
There are two ways to end cruise
control:
.To disengage cruise control;
step lightly on the brake pedal or
lightly tap or press the clutch, for
manual transmissions.
.To turn off the cruise control,
move the cruise control lever
to

Erasing Speed Memory
The cruise control set speed is
erased from memory by moving the
cruise control lever to
9or if the
ignition is turned off.
Fuel
Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Look for the TOP TIER label on the
fuel pump to ensure gasoline meets
enhanced detergency standards
developed by auto companies. A list
of marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.
Recommended Fuel
Use regular unleaded gasoline with
a posted octane rating of 87 or
higher. If the octane rating is less
than 87, an audible knocking noise,
commonly referred to as spark
knock, might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. If heavy knocking is heard
when using gasoline rated at
87 octane or higher, the engine
needs service.

Vehicle Care 10-27
.Fill the washer fluid tank only
three-quarters full when it is
very cold. This allows for
fluid expansion if freezing
occurs, which could damage
the tank if it is
completely full.
.Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint.
Brakes
This vehicle has front disc brakes
and rear drum brakes.
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications in Capacities and
Specifications on page 12‑2. Rear drum brakes do not have wear
indicators, but if a rear brake
rubbing noise is heard, have the
rear brake linings inspected
immediately. Rear brake drums
should be removed and inspected
each time the tires are removed for
rotation or changing. Drum brakes
have an inspection hole to inspect
lining wear during scheduled
maintenance. When the front brake
pads are replaced, have the rear
brakes inspected, too.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
