mountain roads, but then you would
also want to use the brakes off
and on.
1 (First):This position reduces
vehicle speed even more than
2 (Second) without using the brakes.
You can use it on very steep hills,
or in deep snow or mud. If the shift
lever is put in 1 (First) while the
vehicle is moving forward, the
transmission will not shift into first
gear until the vehicle is going slowly
enough.
Notice: Spinning the tires or
holding the vehicle in one place
on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.Manual Transmission
This is your shift pattern.
Here is how to operate the manual
transmission:
1 (First): Press the clutch pedal
and shift into 1 (First). Then, slowly
let up on the clutch pedal as you
slowly press down on the
accelerator pedal.
You can shift into 1 (First) when you
are going less than 30 km/h
(20 mph). If you have come to a
complete stop and it is hard to shift into 1 (First), put the shift lever in
Neutral and let up on the clutch.
Then press the clutch pedal back
down and shift into 1 (First).
2 (Second):
Press the clutch pedal
as you let up on the accelerator
pedal and shift into 2 (Second).
Then, slowly let up on the clutch
pedal as you press the accelerator
pedal.
3 (Third), 4 (Fourth) and 5 (Fifth):
Shift into 3 (Third), 4 (Fourth) and
5 (Fifth) the same way you do for
2 (Second). Slowly let up on the
clutch pedal as you press the
accelerator pedal.
To stop, let up on the accelerator
pedal and press the brake pedal.
Just before the vehicle stops, press
the clutch pedal and the brake
pedal, and shift to Neutral.
Neutral: Use this position when
you start or idle the engine.

Drive Systems
Four-Wheel Drive
If the vehicle has four-wheel
drive, you can send the engine's
driving power to all four wheels for
extra traction. To get the best
performance out of four-wheel
drive, you must be familiar with its
operation. Read this section before
using four-wheel drive. You should
use two-wheel drive high for most
normal driving conditions.
Notice:Driving on clean, dry
pavement in four-wheel drive for
an extended period of time can
cause premature wear on the
vehicle's powertrain. Do not drive
on clean, dry pavement in
Four-Wheel Drive for extended
periods of time. Notice:
If the vehicle has
four-wheel drive and the different
size spare tire is installed on the
vehicle, do not drive in four-wheel
drive until you can have your flat
tire repaired and/or replaced. You
could damage the vehicle, and
the repair costs would not be
covered by your warranty. Never
use four-wheel drive when the
different size spare tire is
installed on the vehicle.
Notice: If the vehicle has
four-wheel drive and the compact
spare tire is installed on the
vehicle, do not drive in four-wheel
drive until you can have the flat
tire repaired and/or replaced. You
could damage the vehicle, and
the repair costs would not be
covered by your warranty. Never
use four-wheel drive when the
compact spare tire is installed on
the vehicle.
The transfer case buttons are
located to the right of the steering
wheel on the instrument panel.

Shifting from Four-Wheel Low to
Two-Wheel High or
Four-Wheel High
To shift from Four-Wheel Low to
Two-Wheel High or Four-Wheel
High, the vehicle must be stopped
or moving less than 5 km/h (3 mph)
with the transmission in N (Neutral)
for an automatic transmission or the
clutch pedal pressed for a manual
transmission. The preferred method
for shifting out of Four-Wheel Low is
to have your vehicle moving
1.6 to 3.2 km/h (1 to 2 mph).
Press and release the Four-Wheel
High or Two-Wheel High button. You
must wait for the Four-Wheel High
or Two-Wheel High indicator light to
stop flashing and stay on before
shifting the transmission into gear or
releasing the clutch pedal.
If the Four-Wheel High or
Two-Wheel High button is pressed
when the vehicle is in gear and/or
moving faster than 5 km/h (3 mph),
the Four-Wheel High or Two-WheelHigh indicator light will flash for
30 seconds but not complete the
shift.
Shifting to Neutral
Use N (Neutral) when you plan to
tow the vehicle. See
Recreational
Vehicle Towing on page 10‑90 for
towing instructions. To shift the
transfer case into N (Neutral) do the
following:
1. Set the parking brake.
2. Start the vehicle.
3. Press the regular brake pedal and shift the transmission in
N (Neutral), or press in the clutch
for vehicles with a manual
transmission.
4. Shift the transfer case to Two-Wheel High.
5. Press and hold the Two-Wheel High and Four-Wheel Low
buttons at the same time for
10 seconds. The N (Neutral) light will come on when the transfer
case shift to N (Neutral) is
complete.
6. Press and hold the regular brake pedal and shift the transmission
to R (Reverse) for one second,
then shift the transmission to
D (Drive) for one second,
or 1 (First) for vehicles with
manual transmissions, and let
out the clutch to insure the
transfer case is in N (Neutral).
If the transfer case is not in
N (Neutral), repeat this
procedure starting at Step 3.
7. Turn the engine off by turning the key to ACC/ACCESSORY.
8. Place the transmission shift lever in P (Park), or 1 (First) for
vehicles that have a manual
transmission.
9. Turn the ignition to LOCK/OFF.

Shifting Out of Neutral
After towing the vehicle, you will
have to shift out of N (Neutral) in
order to drive. To shift out of
N (Neutral), do the following:
1. Set the parking brake and applythe regular brake pedal.
2. Start a vehicle with an automatic transmission in P (Park). Use
1 (First) for vehicles with a
manual transmission.
3. Shift the transmission to N (Neutral), or press the clutch
pedal for vehicles with a manual
transmission.
4. Press the button for the desired transfer case shift position
(Two-Wheel High, Four-Wheel
High, or Four-Wheel Low).
5. After the transfer case has shifted out of N (Neutral), the
indicator light will go out.
6. Release the parking brake.
7. Shift the transmission to the desired position.Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
on page 5‑16.
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, 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
the driver steer around the obstacle
while braking hard.

9-46 Driving and Operating
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 (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.

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
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.

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,
or if the vehicle experiences
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
10% 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
the life of spark plugs and the
performance of the emission control
system could be affected. The
malfunction indicator lamp might
turn on. If this occurs, return to your
dealer for service.

Filling the Tank
{WARNING
Fuel vapor burns violently and a
fuel fire can cause bad injuries.
To help avoid injuries to you and
others, read and follow all the
instructions on the fuel pump
island. Turn off the engine when
refueling. Do not smoke near fuel
or when refueling the vehicle. Do
not use cellular phones. Keep
sparks, flames, and smoking
materials away from fuel. Do not
leave the fuel pump unattended
when refueling the vehicle. This is
against the law in some places.
Do not re-enter the vehicle while
pumping fuel. Keep children away
from the fuel pump; never let
children pump fuel.
The tethered fuel cap is located
behind a hinged fuel door on the
driver side of the vehicle.
To remove the fuel cap, turn it
slowly counterclockwise.
While refueling, hang the tethered
fuel cap from the hook on the
fuel door.
{WARNING
Fuel can spray out on you if you
open the fuel cap too quickly.
If you spill fuel and then
something ignites it, you could be
badly burned. This spray can
happen if the tank is nearly full,
and is more likely in hot weather.
Open the fuel cap slowly and wait
for any hiss noise to stop. Then
unscrew the cap all the way.
Be careful not to spill fuel. Do not
top off or overfill the tank and wait a
few seconds after you have finished
pumping before removing the
nozzle. Clean fuel from painted
surfaces as soon as possible. See
“Washing the Vehicle” in
Exterior Care.
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

Black plate (55,1)Chevrolet Colorado Owner Manual - 2011
Driving and Operating 9-55
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 5‑25
and Malfunction Indicator Lamp on
page 5‑12 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 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 5‑12.
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
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.
(Continued)
WARNING (Continued)
.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.
