Here is how to avoid setting off the
alarm by accident:
.If you do not want to activate the
theft-deterrent system, the
vehicle should be locked with
the door key after the doors are
closed.
.Always unlock a door with the
RKE transmitter. Unlocking a
door any other way will set off
the alarm.
If you set off the alarm by accident,
you can turn off the alarm by
pressing UNLOCK on the RKE
transmitter. The alarm will not stop
if you try to unlock a door any
other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, activate the system by locking the doors
with the RKE transmitter. 2. Unlock the door with the manual
door lock and open the door.
This should set off the alarm.
3. To turn the alarm off, press the UNLOCK button on the RKE
transmitter or start the engine.
If the alarm does not sound when it
should but the lights flash, check to
see if the horn works. The horn fuse
may be blown. To replace the fuse,
see Fuses and Circuit Breakers on
page 10‑39.
If the alarm does not sound or the
front turn signal lamps do not flash,
see your dealer for service.

Immobilizer Operation
(PASS-Key III+
Canada Only)
This vehicle has a passive
theft-deterrent system.
The system is automatically armed
when the key is removed from the
ignition.
The system is automatically
disarmed when the key is turned
to ON/RUN.
You do not have to manually arm
or disarm the system.
The security light comes on if
there is a problem with arming or
disarming the theft-deterrent
system.
The key uses a transponder that
matches an immobilizer control unit
in the vehicle. Only the correct key
starts the vehicle. If the key is ever
damaged, the vehicle may not start.
When trying to start the vehicle,
if the engine does not start and
the security light comes on, there

Keys, Doors, and Windows 2-11
may be a problem with the
theft-deterrent system. Turn the
ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. Check
the fuse. SeeFuses and Circuit
Breakers on page 10‑39. If the
engine still does not start with the
other key, the vehicle needs service.
If the vehicle does start, the first key
may be faulty. See your dealer who
can service the theft-deterrent
system and have a new key made.
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys
can be programmed for the vehicle.
The following procedure is for
programming additional keys only.
Canadian Owners: If the keys are
lost or damaged, only a dealer can
service the theft-deterrent system to
have new ones made. Two current
driver's keys are required to
program additional keys. To program a new key:
1. Verify that the new key has
PK3+ stamped on it.
2. Insert the current driver's key in the ignition and start the engine.
If the engine does not start see
your dealer for service.
3. After the engine has started, turn the key to LOCK/OFF, and
remove the key.
4. Insert the second current driver's key in the ignition and start the
engine within ten seconds of
removing the previous key. If the
engine does not start see your
dealer for service.
5. After the engine has started, turn the key to LOCK/OFF, and
remove the key. Insert the key
to be programmed and turn it to
ON/RUN within ten seconds of
removing the previous key.
The security light turns off once
the key has been programmed. 6. Repeat Steps 1 through 5 if
additional keys are to be
programmed.
If the security light comes on and
stays on while driving, the engine
will restart if you turn it off. However,
the theft-deterrent system is not
working properly and must be
serviced by your dealer. The
vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside
Assistance. 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.

Additional windshield breakage
may also occur from the right front
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some
new parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the need
to replace other parts.
.Your vehicle has a crash
sensing and diagnostic module
which records information after
a crash. SeeVehicle Data
Recording and Privacy on
page 13‑19 andEvent Data
Recorders on page 13‑19.
.Let only qualified technicians
work on the airbag system.
Improper service can mean that
the airbag system will not work
properly. See your dealer for
service.
Passenger Sensing
System
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, if equipped,
is visible on the instrument panel
when the vehicle is started.
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
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. When the
system check is complete, either
the word ON or OFF, or the symbol
for on or off will be visible. See
Passenger Airbag Status Indicator
on page 5‑11.
The passenger sensing system will
turn off the right front passenger
frontal airbag under certain

Black plate (28,1)Chevrolet Colorado Owner Manual - 2012
3-28 Seats and Restraints
The passenger sensing system is
designed to turn off the right front
passenger airbag if:
.The right front passenger seat is
unoccupied.
.The system determines that an
infant is present in a rear-facing
infant seat.
.The system determines that a
small child is present in a child
restraint.
.The system determines that a
small child is present in a
booster seat.
.A right front passenger takes
his/her weight off of the seat for
a period of time.
.The right front passenger seat is
occupied by a smaller person,
such as a child who has
outgrown child restraints.
.Or, if there is a critical problem
with the airbag system or the
passenger sensing system.
When the passenger sensing
system has turned off the right front
passenger frontal airbag, the off
indicator will light and stay lit to
remind you that the airbag is off.
See Passenger Airbag Status
Indicator on page 5‑11.
The passenger sensing system is
designed to turn on (may inflate) the
right front passenger frontal airbag
anytime the system senses that
a person of adult size is sitting
properly in the right front passenger
seat. When the passenger sensing
system has allowed the airbag to be
enabled, the on indicator will light
and stay lit to remind you that the
airbag is active. For some children who have
outgrown child restraints and for
very small adults, the passenger
sensing system may or may not
turn off the right front passenger's
frontal airbag, depending upon
the person's seating posture and
body build. Everyone in your vehicle
who has outgrown child restraints
should wear a safety belt
properly
—whether or not there
is an airbag for that person.
{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. See Airbag Readiness
Light on page 5‑10 for more
information, including important
safety information.

Seats and Restraints 3-31
A thick layer of additional material,
such as a blanket or cushion,
or aftermarket equipment such
as seat covers, seat heaters, and
seat massagers can affect how
well the passenger sensing system
operates. We recommend that
you not use seat covers or other
aftermarket equipment except when
approved by GM for your specific
vehicle. SeeAdding Equipment to
the Airbag-Equipped Vehicle on
page 3‑32 for more information
about modifications that can affect
how the system operates.
{WARNING
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information on page 13‑17.
{WARNING
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
