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.

Adding non-dealer/non-retailer
accessories can affect the vehicle's
performance. SeeAccessories and
Modifications on page 10‑3.
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 9‑46.
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 10‑29 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 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.

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.

9-46 Driving and Operating
Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
If the brakes are applied, the cruise
control shuts off.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.If the vehicle's StabiliTrak
®/Traction
Control System (TCS) begins to
limit wheel spin while the cruise
control is on, the cruise control
automatically disengages. See
StabiliTrak
®System on page 9‑44 or
Traction Control System (TCS) on
page 9‑42. When road conditions
allow you to safely use it again,
the cruise control can be turned
back on.
These controls are located at the
end of the multifunction lever.

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

9-48 Driving and Operating
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.

Black plate (49,1)Chevrolet Colorado Owner Manual - 2012
Driving and Operating 9-49
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.
Gasoline Specifications
(U.S. and Canada Only)
At a minimum, gasoline should
meet ASTM specification
D 4814 in the United States or
CAN/CGSB‐3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeFuel Additives
on page 9‑50 for additional
information.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog‐check test.
See
Malfunction Indicator Lamp on
page 5‑13. If this occurs, return to
your authorized dealer for diagnosis.
If it is determined that the condition
is caused by the type of fuel used,
repairs might not be covered by the
vehicle warranty.
Fuels in Foreign
Countries
Never use leaded gasoline or any
other fuel not recommended in the
previous text on fuel. Costly repairs
caused by use of improper fuel
would not be covered by the vehicle
warranty.
To check the fuel availability, ask an
auto club, or contact a major oil
company that does business in the
country where you will be driving.

Fuel Additives
To provide cleaner air, all gasolines
in the United States are now
required to contain additives that
help prevent engine and fuel system
deposits from forming, allowing the
emission control system to work
properly. In most cases, nothing
should have to be added to the fuel.
However, some gasolines contain
only the minimum amount of
additive required to meet U.S.
Environmental Protection Agency
regulations. To help keep fuel
injectors and intake valves clean
and avoid problems due to dirty
injectors or valves, look for gasoline
that is 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 the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of GM Fuel System
Treatment PLUS, added to the fuel
tank at every engine oil change,
can help clean deposits from fuel
injectors and intake valves. GM Fuel
System Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might
be available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
15% ethanol must not be used in
vehicles that were not designed for
those fuels.
Notice:
This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
spark plug life and affect emission
control system performance. The
malfunction indicator lamp might
turn on. If this occurs, return to your
dealer for service.
