5-6 Instruments and Controls
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.

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 5‑24 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 10‑22 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.

5-10 Instruments and Controls
This chime and light are repeated if
the driver remains unbuckled and
the vehicle is in motion. If the driver
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(s), passenger
sensing system, 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 3‑20.
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.

{WARNING
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
If there is a problem with the airbag
system, an airbag Driver Information
Center (DIC) message can also
come on. See Vehicle Messages on
page 5‑22 for more information.
Passenger Airbag Status
Indicator
If the vehicle has one of the
passenger airbag status indicators
pictured in the following illustrations,
then the vehicle has a passenger
sensing system for the right front
passenger position. The passenger
airbag status indicator is on the
instrument panel. See Passenger
Sensing System on page 3‑26 for
important safety information.
In addition, if the vehicle has a
passenger sensing system for the
right front passenger position, the
label on the vehicle's sun visors
refer to “ADVANCED AIRBAGS”.
United States
Canada and Mexico
When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds
as a system check. Then, after
several more seconds, the status
indicator will light either ON or OFF,
or either the on or off symbol to let
you know the status of the right front
passenger frontal airbag.

Black plate (12,1)Chevrolet Colorado Owner Manual - 2012
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

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 5‑22 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 the operation
of the vehicle to ensure emissions
are at acceptable levels, to produce
a cleaner environment. This light
comes on when the vehicle is
placed in ON/RUN, as a check to
show it is working. If it does not,
have the vehicle serviced by your
dealer. SeeIgnition Positions on
page 9‑23 for more information.
If the malfunction indicator lamp
comes on and stays on while the
engine is running, this indicates that
there is an OBD II problem and
service is required. Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the service technician in correctly
diagnosing any malfunction.
Notice:
If the vehicle is
continually driven with this
light on, the emission controls
might not work as well, the
vehicle fuel economy might not
be as good, and the engine might
not run as smoothly. This could
lead to costly repairs that might
not be covered by the vehicle
warranty.
Notice: Modifications made
to the engine, transmission,
exhaust, intake, or fuel system
of the vehicle or the replacement
of the original tires with other
than those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this
light to come on. Modifications
to these systems could lead to costly repairs not covered by
the vehicle warranty. This
could also result in a failure
to pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications on
page 10‑3.
This light comes on during a
malfunction in one of two ways:
Light Flashing:
A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to
the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible.

5-14 Instruments and Controls
If the light continues to flash, stop
and park the vehicle. Turn the
vehicle off, wait at least 10 seconds,
and restart the engine. If the light
is still flashing, follow the previous
steps and see your dealer for
service as soon as possible.
Light On Steady:An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emission system malfunction:
.Check that the fuel cap is
fully installed. See Filling the
Tank on page 9‑51. The
diagnostic system can determine
if the fuel cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.Check that good quality fuel
is used. Poor fuel quality
causes the engine not to run
as efficiently as designed and
may cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It will require at least one full tank of
the proper fuel to turn the light off.
See Recommended Fuel on
page 9‑49.
If none of the above have made
the light turn off, your dealer can
check the vehicle. The dealer
has the proper test equipment
and diagnostic tools to fix any
mechanical or electrical problems
that might have developed.Emissions Inspection and
Maintenance Programs
Some local governments may have
programs to inspect the on-vehicle
emission control equipment. For
the inspection, the emission system
test equipment is connected
to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.

Black plate (15,1)Chevrolet Colorado Owner Manual - 2012
Instruments and Controls 5-15
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off.
.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or run
down. The diagnostic system
is designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need
to be working
If the warning light comes on, there
could be a brake problem. Have the
brake system inspected right away.
EnglishMetric
This light comes on briefly when the
ignition key is turned to ON/RUN.
If it does not, have it fixed so it
will be ready to warn if there is a
problem.
When the ignition is on, the brake
system warning light comes on
when the parking brake is set. See
Parking Brake on page 9‑41 for
more information. The light stays
on if the parking brake does not
release fully. If it stays on after the
parking brake is fully released, it
means there is a brake problem.
