suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake
The parking brake pedal is located
to the left of the brake pedal, near
the driver door.
To set the parking brake, hold the
brake pedal down, then push the
parking brake pedal down to its
fully-applied position.
A chime will activate and the
brake warning light, located on the
instrument panel, will flash when
the parking brake is applied and the
vehicle is moving at least 5 km/h
(3 mph) for at least three seconds.The chime will deactivate and the
light will turn off when the parking
brake is set and the vehicle is
moving below 5 km/h (3 mph). See
Brake System Warning Light on
page 5‑15.
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.

9-42 Driving and Operating
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 9‑53.
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.

Black plate (43,1)Chevrolet Colorado Owner Manual - 2012
Driving and Operating 9-43
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 9‑46.
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 TCS/StabiliTrak light will flash
on the instrument panel cluster
when the TCS system or StabiliTrak
is both on and activated.
The TCS/StabiliTrak button is
located on the instrument panel.
To turn off TCS, press and release
the TCS/StabiliTrak button. The
StabiliTrak OFF light comes on in
the instrument panel cluster, and
TRAC OFF comes on the DIC.
To turn TCS back on, press and
release the TCS/StabiliTrak button.

Black plate (45,1)Chevrolet Colorado Owner Manual - 2012
Driving and Operating 9-45
This can cause the brake-traction
control to activate constantly. SeeIf
the Vehicle Is Stuck on page 9‑15.
The TCS/StabiliTrak light will flash
on the instrument panel cluster
when the TCS system or StabiliTrak
is both on and activated.
The TCS/StabiliTrak button is
located on the instrument panel.
To turn off TCS and StabiliTrak,
press and hold the TCS/StabiliTrak
button until the TRAC OFF and
STAB SYS OFF messages come on
the DIC and the StabiliTrak/TCS
OFF light comes on the instrument
panel. To turn TCS and StabiliTrak
back on, press and release the
TCS/StabiliTrak button.
When the TCS or StabiliTrak system
is turned off, the StabiliTrak OFF
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
TCS/StabiliTrak light flashes when
either system is actively working.
See
Traction Control System (TCS)
on page 9‑42 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.

Driving and Operating 9-47
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 Tat 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
from
RtoS. 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 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
9.
Erasing Speed Memory
The cruise control set speed is
erased from memory by moving the
cruise control lever to
9or if the
vehicle 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.

When replacing the fuel cap, turn
it clockwise until it clicks. Make
sure the cap is fully installed. The
diagnostic system can determine
if the fuel cap has been left off or
improperly installed. This would
allow fuel to evaporate into the
atmosphere. If the fuel cap is not
properly installed, the FUEL CAP
message appears on the Driver
Information Center (DIC) and the
check engine light will be lit on the
instrument panel cluster. SeeFuel
System Messages on page 5‑24
and Malfunction Indicator Lamp on
page 5‑13 for more information.
{WARNING
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel
by shutting off the pump or by
notifying the station attendant.
Leave the area immediately. Notice:
If a new fuel cap is
needed, be sure to get the right
type of cap from your dealer. The
wrong type of fuel cap might not
fit properly, might cause the
malfunction indicator lamp to
light, and could damage the fuel
tank and emissions system. See
Malfunction Indicator Lamp on
page 5‑13.
Filling a Portable Fuel
Container
{WARNING
Never fill a portable fuel container
while it is in the vehicle. Static
electricity discharge from the
container can ignite the fuel
vapor. You can be badly burned
(Continued)
WARNING (Continued)
and the vehicle damaged if this
occurs. To help avoid injury to you
and others:
.Dispense fuel only into
approved containers.
.Do not fill a container while
it is inside a vehicle, in a
vehicle's trunk, pickup bed,
or on any surface other than
the ground.
.Bring the fill nozzle in
contact with the inside of the
fill opening before operating
the nozzle. Contact should be
maintained until the filling is
complete.
.Do not smoke while
pumping fuel.
.Do not use a cellular phone
while pumping fuel.

10-26 Vehicle Care
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.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.

Vehicle Care 10-39
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of fires caused by electrical
problems.
Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure
you replace a bad fuse with a new
one of the identical size and rating.
If you ever have a problem on the
road and do not have a spare fuse,
you can borrow one that has the
same amperage. Just pick some
feature of the vehicle that you can
get along without—like the radio
or cigarette lighter —and use its
fuse, if it is the correct amperage.
Replace it as soon as you can.
Engine Compartment
Fuse Block
The engine compartment fuse block
is located on the driver side of the
engine compartment. See Engine
Compartment Overview on
page 10‑6 for more information on
location.
