Ignition Positions
The ignition switch has four different
positions.
To shift out of P (Park), turn the
ignition to ON/RUN and apply the
regular brake pedal.
Notice:Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer. A (STOPPING THE ENGINE/
LOCK/OFF):
When the vehicle is
stopped, turn the ignition switch to
LOCK/OFF to turn the engine off.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) on
page 9‑30
This position locks the ignition.
It also locks the transmission on
automatic transmission vehicles.
It locks the steering wheel on
manual transmission vehicles.
The key can only be removed in
LOCK/OFF.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
In an emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force. 2. Shift the vehicle to neutral. This
can be done while the vehicle is
moving. After shifting to neutral,
firmly apply the brakes and steer
the vehicle to a safe location.
3. Come to a complete stop. Shift to P (Park) with an automatic
transmission, or neutral with a
manual transmission. Turn the
ignition to LOCK/OFF.
4. Set the parking brake. See Parking Brake on page 9‑44
On vehicles with an automatic
transmission, the shift lever must be
in P (Park) to turn the ignition switch
to LOCK/OFF.
The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from right to left while turning the
key to ACC/ACCESSORY. If this
doesn't work, then the vehicle needs
service.

Black plate (28,1)Chevrolet Colorado Owner Manual - 2011
9-28 Driving and Operating
B (ACC/ACCESSORY) :This is
the position in which you can
operate the electrical accessories or
items plugged into the accessory
power outlets. On automatic
transmission vehicles, this position
unlocks the ignition. On manual
transmission vehicles, it unlocks the
ignition and steering wheel. Use this
position if the vehicle must be
pushed or towed.
C (ON/RUN): This position can
be used to operate the electrical
accessories and to display some
instrument panel cluster warning
and indicator lights. The switch
stays in this position when the
engine is running. The transmission
is also unlocked in this position on
automatic transmission vehicles.
If you leave the key in the ACC/
ACCESSORY or ON/RUN position
with the engine off, the battery could
be drained. You may not be able to
start your vehicle if the battery is
allowed to drain for an extended
period of time. D (START):
This is the position that
starts the engine. When the engine
starts, release the key. The ignition
switch returns to ON/RUN for
driving.
A warning tone will sound when the
driver door is opened, the ignition is
in ACC/ACCESSORY or LOCK/OFF
and the key is in the ignition.
Starting the Engine
Place the transmission in the
proper gear.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
vehicle when it is already moving,
use N (Neutral) only.
Notice: Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
Manual Transmission
The shift lever should be in
N (Neutral) and the parking brake
engaged. Hold the clutch pedal
down to the floor and start the
engine. The vehicle will not start if
the clutch pedal is not all the
way down.
Starting Procedure
1. With your foot off the accelerator pedal, turn the ignition key to
START. When the engine starts,
let go of the key. The idle speed
will go down as the engine
warms. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently to allow the
oil to warm up and lubricate all
moving parts.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the

Automatic
Transmission
The vehicle has a shift lever on the
steering column.
It features an electronic shift
position indicator within the
instrument cluster. This display is
powered anytime the shift lever is
capable of being moved out of
P (Park). This means that if the
ignition is turned off, but not in
LOCK/OFF, there will be a small
current drain on the battery which
could discharge the battery over a
period of time. If you need to leave
the key in the ignition but not in
LOCK/OFF for an extended period,
it is recommended that youdisconnect the battery cable from
the battery to prevent discharging
the battery.
There are several different positions
for the shift lever.
P (Park):
This position locks the
rear wheels. It is the best position to
use when you start the engine
because the vehicle cannot move
easily.
{WARNING
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running unless you
have to. If you have left the
engine running, the vehicle can
move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
(Continued)
WARNING (Continued)
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park (Automatic
Transmission) on page 9‑30.
If you are pulling a trailer, see
Driving Characteristics and
Towing Tips on page 9‑56.
Make sure the shift lever is fully in
P (Park) before starting the engine.
The vehicle has an automatic
transmission shift lock control
system. You must fully apply the
brake pedal before you can shift
from P (Park) when the ignition key
is in ON/RUN. If you cannot shift out
of P (Park), ease pressure on the
shift lever by pushing the shift lever
all the way into P (Park) as you
maintain brake application. Then
move the shift lever into another
gear. See Shifting Out of Park
(Automatic Transmission) on
page 9‑32.

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.

Black plate (44,1)Chevrolet Colorado Owner Manual - 2011
9-44 Driving and Operating
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
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.

Black plate (58,1)Chevrolet Colorado Owner Manual - 2011
9-58 Driving and Operating
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
much farther beyond the passed
vehicle before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, move that hand
to the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer will not strike soft
shoulders, curbs, road signs, trees
or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
flash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also flash, telling
other drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. For this reason you may think other drivers are seeing the
signal when they are not. It is
important to check occasionally to
be sure the trailer bulbs are still
working.
Driving On Grades
Reduce speed and shift to a lower
gear
before starting down a long
or steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
Vehicles with automatic
transmissions can tow in D (Drive),
but you may want to shift to a lower
gear selection if the transmission
shifts too often (e.g., under heavy
loads and/or hilly conditions). If the
vehicle has a manual transmission it
is better not to use the highest gear.
When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at
a lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
