2011 CHEVROLET COLORADO engine

Black plate (12,1)Chevrolet Colorado Owner Manual - 2011
2-12 Keys, Doors and Windows
Immobilizer Operation
(Passlock U.S. Only)
Passlock®is a passive
theft-deterrent system that enables
fuel if the vehicle is started with a
valid key. If an incorrect key is used
or the ignition lock cylinder is
tampered with, the fuel system is
disabled and the vehicle does not
start.
The security light turns off
approximately five seconds after the
engine is started. See Security Light
on page 5‑18.
If the engine stalls and the security
light flashes, wait about 10 minutes
until the light stops flashing before
trying to restart the engine. Release
the key from START as soon as the
engine starts.
If the engine does not start after
three tries, the vehicle needs
service. If the engine is running and the
security light comes on, the engine
restarts if you turn the engine off.
However, the Passlock®system is
not working properly and must be
serviced by your dealer. The vehicle
is not protected by Passlock
®at this
time. See your dealer for service.
In an emergency, call the Roadside
Assistance Center. See Roadside
Assistance Program (U.S. and
Canada) on page 13‑7 orRoadside
Assistance Program (Mexico) on
page 13‑9.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.
Exterior Mirrors
Convex Mirrors
{WARNING
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See After
an Airbag Inflates?
After the frontal airbags inflate, they
quickly deflate, so quickly that some
people may not even realize the
airbags inflated. Roof-rail airbags
may still be at least partially inflated
for some time after they deploy.
Some components of the airbag
module may be hot for several
minutes. For location of the airbag
modules, seeWhat Makes an
Airbag Inflate? on page 3‑30.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not
prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
{WARNING
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors
(if equipped with power door locks),
turn the interior lamps on, flash the
hazard warning flashers, turn off the
radio, and shut off the fuel system
after the airbag inflates. You can
lock the doors again by using the door lock. The interior lamps and
hazard warning flashers will
deactivate after approximately
15 minutes.
{WARNING
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.

Ashtrays
The vehicle may have a removable
ashtray and cigarette lighter.
The ashtray is located in the center
console area. The ashtray can be
removed for cleaning. When the
ashtray is removed, this area can
also be used as a cupholder.
Notice:If papers, pins, or other
flammable items are put in the
ashtray, hot cigarettes or other
smoking materials could ignite
them and possibly damage the
vehicle. Never put flammable
items in the ashtray.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.
Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.Chime Level Adjustment
The radio is used to adjust the
vehicle's chime level. To change the
volume level of the chime, press
and hold pushbutton 6 with the
ignition on and the radio power off.
The volume level will change from
the normal level to loud, and LOUD
will appear on the radio display. To
change back to the default or
normal setting, press and hold
pushbutton 6 again. The volume
level will change from the loud level
to normal, and NORMAL will appear
on the radio display. Each time the
chime volume is changed, three
chimes will sound to indicate the
new volume selected. Removing the
radio and not replacing it with a
factory radio or chime module will
disable vehicle chimes.

Black plate (8,1)Chevrolet Colorado Owner Manual - 2011
5-8 Instruments and Controls
Speedometer
The speedometer shows the speed
in both miles per hour (mph) and
kilometers per hour (km/h).
Odometer
The odometer shows how far the
vehicle has been driven, in either
miles (used in the United States) or
kilometers (used in Canada).
The odometer mileage can be
checked without the vehicle running
by pressing the trip information
stem. See“Odometer” underDriver
Information Center (DIC) on
page 5‑19 for more information.
If the cluster is replaced the new
one will automatically detect and
update the vehicle's accumulated
mileage.
Trip Odometer
The vehicle has a trip odometer that
indicates how far the vehicle has
been driven since the trip odometer
was last set to zero.
See “Trip Odometer” underDriver
Information Center (DIC) on
page 5‑19 for more information.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Notice:If the engine is operated
with the tachometer in the shaded
warning area, the vehicle could
be damaged, and the damages
would not be covered by the
vehicle warranty. Do not operate
the engine with the tachometer in
the shaded warning area.
Fuel Gauge
When the ignition is on, the fuel
gauge shows how much fuel the
vehicle has remaining in the
fuel tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.

Black plate (9,1)Chevrolet Colorado Owner Manual - 2011
Instruments and Controls 5-9
Here are four things that some
owners ask about. None of these
indicate a problem with the vehicle's
fuel gauge:
.At the gas station, the gas pump
shuts off before the gauge
reads full.
.It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
.The gauge moves a little while
turning a corner or speeding up.
.The gauge does not go back to
empty when the ignition is
turned off.
When the fuel in the fuel tank is low,
a LOW FUEL message will display
on the Driver Information
Center (DIC). See Fuel System
Messages on page 5‑25 for more
information.
Engine Coolant
Temperature Gauge
This gauge shows the engine
coolant temperature.
If the gauge pointer is near the top
of the gauge, the engine is too hot.
It means that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull the vehicle off the
road, stop the vehicle and turn off
the engine as soon as possible. See
Engine Overheating on
page 10‑23 for more information.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
When the engine is started, a chime
sounds for several seconds to
remind a driver to fasten the safety
belt, unless the driver safety belt is
already buckled.
The safety belt light comes on and
stays on for several seconds, then
flashes for several more.
This chime and light are repeated if
the driver remains unbuckled and
the vehicle is in motion. If the driver

Black plate (10,1)Chevrolet Colorado Owner Manual - 2011
5-10 Instruments and Controls
safety belt is already buckled,
neither the chime nor the light
comes on.
Passenger Safety Belt
Reminder Light
For vehicles equipped with the
passenger safety belt reminder light,
several seconds after the engine is
started, a chime sounds for several
seconds to remind the front
passenger to buckle their safety
belt. The passenger safety belt light,
located on the instrument panel,
comes on and stays on for several
seconds and then flashes for
several more.This chime and light are repeated if
the passenger remains unbuckled
and the vehicle is in motion.
If the passenger safety belt is
buckled, neither the chime nor the
light comes on.
The front passenger safety belt
warning light and chime may turn on
if an object is put on the seat such
as a briefcase, handbag, grocery
bag, laptop or other electronic
device. To turn off the warning light
and or chime, remove the object
from the seat or buckle the
safety belt.
Airbag Readiness Light
The system checks the airbag's
electrical system for possible
malfunctions. If the light stays on it
indicates there is an electrical
problem. The system check includes
the airbag sensor, the
pretensioners, the airbag modules,
the wiring and the crash sensing
and diagnostic module. For more
information on the airbag system,
seeAirbag System on page 3‑26.
The airbag readiness light flashes
for a few seconds when the engine
is started. If the light does not come
on then, have it fixed immediately.

Black plate (12,1)Chevrolet Colorado Owner Manual - 2011
5-12 Instruments and Controls
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the right
front passenger frontal airbag is
enabled (may inflate).
If the word OFF or the off symbol is
lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the right front
passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
(Continued)
WARNING (Continued)
Light on page 5‑10 for more
information, including important
safety information.
Charging System Light
This light comes on briefly when the
ignition key is turned to START, but
the engine is not running, as a
check to show it is working.
If it does not, have the vehicle
serviced by your dealer.
The light should go out once the
engine starts. If it stays on,
or comes on while driving, there
could be a problem with the
charging system. A charging system
message in the Driver Information Center (DIC) can also appear. See
Battery Voltage and Charging
Messages on page 5‑23
for more
information. This light could indicate
that there are problems with a
generator drive belt, or that there is
an electrical problem. Have it
checked right away. If the vehicle
must be driven a short distance with
the light on, turn off accessories,
such as the radio and air
conditioner.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
