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.
Manual Mirrors
Adjust the mirrors by pressing the
mirror up and down and left and
right so you can see a clear view
behind you.

Seats and Restraints 3-9
A. Hook and Loop Fastener
To store the seat:
1. Secure the safety belt buckle tothe inboard side of the seat with
the hook and loop fastener (A),
so that it does not move when
not in use.
2. Push the entire seat up until it is flush with the trim panel.
Rear Seats (Crew Cab)
On crew cab models, the rear
seatbacks can be folded forward.
Notice: Folding a rear seat with
the safety belts still fastened may
cause damage to the seat or the
safety belts. Always unbuckle the
safety belts and return them to
their normal stowed position
before folding a rear seat.
To fold a rear seatback:
1. Disconnect the rear center safety belt latch from the
mini-buckle by inserting the tip of the safety belt tongue into the
slot on the buckle. Let the belt
retract.
2. Pull the loop on the outboard
side of the seatback forward
until you hear a click.
3. Fold the seatback forward.

3-10 Seats and Restraints
To return a seatback to the upright
position:
1. Lift the seatback up and push itrearward.
{WARNING
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.
2. Push and pull on the seatback to make sure it is locked in place.
{WARNING
A safety belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash.
(Continued)
WARNING (Continued)
The person wearing the belt could
be seriously injured. After raising
the rear seatback, always check
to be sure that the safety belts
are properly routed and attached,
and are not twisted.
3. Reconnect the center safety belt latch plate to the mini-buckle.
Make sure the safety belt is not
twisted.
4. Push and pull on the latch plate to be sure it is secure.
When the seatback is not in use, it
should be kept in the upright, locked
position.
Safety Belts
This section of the manual
describes how to use safety belts
properly. It also describes some
things not to do with safety belts.
{WARNING
Do not let anyone ride where
a safety belt cannot be worn
properly. In a crash, if you or your
passenger(s) are not wearing
safety belts, injuries can be much
worse than if you are wearing
safety belts. You can be seriously
injured or killed by hitting things
inside the vehicle harder or by
being ejected from the vehicle.
In addition, anyone who is not
buckled up can strike other
passengers in the vehicle. (Continued)

Seats and Restraints 3-13
{WARNING
You can be seriously injured,
or even killed, by not wearing
your safety belt properly.
.Never allow the lap or
shoulder belt to become
loose or twisted.
.Never wear the shoulder belt
under both arms or behind
your back.
.Never route the lap or
shoulder belt over an
armrest.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt except for
the center front passenger position,
if equipped, which has a lap belt.
SeeLap Belt on page 3‑17 for more
information. The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is
adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index.
2. Pick up the latch plate and pull the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If you ever pull the shoulder
portion of a passenger belt out
all the way, the child restraint
locking feature may be engaged.
If this happens, just let the belt
go back all the way and start
again.
Engaging the child restraint
locking feature in the right front
seating position may affect the passenger sensing system,
if equipped. See
Passenger
Sensing System on page 3‑26
for more information.
3. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3‑18.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.

Black plate (18,1)Chevrolet Colorado Owner Manual - 2012
3-18 Seats and Restraints
To make the belt longer, tilt the latch
plate and pull it along the belt.
Buckle, position, and release it the
same way as the lap part of a
lap-shoulder belt.To make the belt shorter, pull its free
end as shown until the belt is snug.
If the belt is not long enough, see
Safety Belt Extender on page 3‑18.
Make sure the release button on the
buckle is positioned so you would
be able to unbuckle the safety belt
quickly if necessary.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. For more information, see the
instruction sheet that comes with
the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors,
and anchorages are all working
properly. Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system

WARNING (Continued)
close to the airbag, as you would
be if you were sitting on the edge
of your seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear your safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
roof-rail airbags.
{WARNING
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured
or killed. Airbags plus(Continued)
WARNING (Continued)
lap-shoulder belts offer protection
for adults and older children, but
not for young children and infants.
Neither the vehicle safety belt
system nor its airbag system
is designed for them. Young
children and infants need the
protection that a child restraint
system can provide. Always
secure children properly in the
vehicle. To read how, see Older
Children on page 3‑34 orInfants
and Young Children on
page 3‑36.
There is an airbag readiness light
on the instrument panel, which
shows the airbag symbol. The system checks the airbag
electrical system for malfunctions.
The light tells you if there is an
electrical problem. See
Airbag
Readiness Light on page 5‑10 for
more information.
Where Are the Airbags?
The driver's airbag is in the middle
of the steering wheel.

Black plate (22,1)Chevrolet Colorado Owner Manual - 2012
3-22 Seats and Restraints
The right front passenger's airbag is
in the instrument panel on the
passenger's side.Driver Side Shown, PassengerSide Similar
If your vehicle has roof-rail airbags
for the driver, right front passenger,
and second row outboard
passengers, they are in the ceiling
above the side windows.
{WARNING
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury
or even death. The path of an
inflating airbag must be kept
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie down
through any door or window
opening. If you do, the path of an
inflating roof-rail airbag will be
blocked.
