system.
The system does not have to be manually
armed or disarmed.
The vehicle is automatically immobilized
when the key is removed from the ignition.
The system is automatically disarmed when
the vehicle is started with the correct key.

immobilizer control unit in the vehicle and
automatically disarms the system. Only an
authorized key starts the vehicle. The vehicle
may not start if the key is damaged.
The security light in the instrument cluster
comes on if there is a problem with arming
or disarming the theft-deterrent system.
When trying to start the vehicle, the
security light comes on briefly when the
ignition is turned on.If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the ignition off and try again.
If the engine still does not start, and the
key appears to be undamaged or the light
continues to stay on, try another ignition
key. If the engine does not start with the
other key, the vehicle needs service. If the
vehicle does start, the first key may be
damaged. See your dealer who can service
the theft-deterrent system and have a new
key made.
Do not leave the transmitter or device that
disarms or deactivates the theft-deterrent
system in the vehicle.

matched to an immobilizer control unit in
your vehicle. Only a correctly matched
transmitter will start the vehicle. If the
transmitter is ever damaged, you may not
be able to start your vehicle.
When trying to start the vehicle, the
security light comes on briefly when the
ignition is turned on.
If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the vehicle off and try again.

Warning
With head restraints that are not
installed and adjusted properly, there is a
greater chance that occupants will suffer
a neck/spinal injury in a crash. Do not
drive until the head restraints for all
occupants are installed and adjusted
properly.
Front Seats
The front seats have adjustable head
restraints in the outboard seating positions.

Chevrolet TRAX Owner Manual (GMNA-Localizing-U.S./Canada-14609828) -

30 Seats and Restraints
Adjust the head restraint so that the top of
the restraint is at the same height as the
top of the occupant's head. This position
reduces the chances of a neck injury in a
crash.
The height of the head restraint can be
adjusted. Pull the head restraint up to raise
it. Try to move the head restraint to make
sure that it is locked in place.
To lower the head restraint, press the
button, located on the top of the seatback,
and push the head restraint down. Try to
move the head restraint after the button is
released to make sure that it is locked in
place.The front seat outboard head restraints are
not removable.
Rear Seats
The rear seats have head restraints in the
outboard seating positions that can be
lowered for better visibility when the rear
seat is unoccupied.
To lower the head restraint, press the
button, located on the top of the seatback,
and push the head restraint down.
When an occupant is in the seat, always
return the head restraint to the upright
position. Pull the head restraint up and push
it rearward until it locks into place. Push and
pull on the head restraint to make sure that
it is locked.
If you are installing a child restraint in the
rear seat, see

will be canceled when the ignition is turned
on. Press the control to use the heated seats
after the vehicle is started.
The heated seat indicator lights do not turn
on during a remote start.
The temperature performance of an
unoccupied seat may be reduced. This is
normal.
The heated seats will not turn on during a
remote start unless the heated seat feature
is enabled in the vehicle personalization
menu. SeeRemote Vehicle Start 017 and
Vehicle Personalization 093.
Folding Seatback
The front passenger seatback may fold flat.
{Warning
If you fold the seatback forward to carry
longer objects, such as skis, be sure any
such cargo is not near an airbag. In a
crash, an inflating airbag might force that
object toward a person. This could cause
severe injury or even death. Secure
objects away from the area in which an
airbag would inflate. For more

information, seeWhere Are the Airbags?
0 46 and
Vehicle Load Limits 0134.
{Warning
Things you put on this seatback can
strike and injure people in a sudden stop
or turn, or in a crash. Remove or secure
all items before driving.
To fold the seatback: 1. Lower the head restraint all the way. See Head Restraints 029.
2. Move the seat as far back as possible. See Seat Adjustment 030.
3. Lift the lever fully and fold the seatback

Pull up on the latch plate to make sure
it is secure. If the belt is not long
enough, seeSeat Belt Extender 043.
Position the release button on the buckle
so that the seat belt could be quickly
unbuckled if necessary.
4. If equipped with a shoulder belt height adjuster, move it to the height that is
right for you. See “Shoulder Belt Height
Adjuster” later in this section for
instructions on use and important safety
information.
5. To make the lap part tight, pull up on the shoulder belt.
To unlatch the belt, push the button on the
buckle. The belt should return to its stowed
position.
Always stow the seat belt slowly. If the seat
belt webbing returns quickly to the stowed
position, the retractor may lock and cannot
be pulled out. If this happens, pull the seat
belt straight out firmly to unlock the
webbing, and then release it. If the webbing
is still locked in the retractor, see your
dealer.
Before a door is closed, be sure the seat belt
is out of the way. If a door is slammed
against a seat belt, damage can occur to
both the seat belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height
adjuster for the driver and front outboard
passenger seating positions.
Adjust the height so the shoulder portion of
the belt is on the shoulder and not falling
off of it. The belt should be close to, but not
contacting, the neck. Improper shoulder belt
height adjustment could reduce the
effectiveness of the seat belt in a crash. See
How to Wear Seat Belts Properly 039.
To move the shoulder belt height adjuster
down, push down on the release button and
move the height adjuster to the desired

But if a seat 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 restraints. For
more information on the proper use and fit
of seat belt extenders see the instruction
sheet that comes with the extender.
Safety System Check
Periodically check the seat belt reminder,
seat belts, buckles, latch plates, retractors,
shoulder belt height adjusters (if equipped),
and seat belt anchorages to make sure they
are all in working order. Look for any other
loose or damaged seat belt system parts
that might keep a seat belt system from
performing properly. See your dealer to
have it repaired. Torn, frayed, or twisted
seat belts may not protect you in a crash.
Torn or frayed seat belts can rip apart under
impact forces. If a belt is torn or frayed,
have it replaced immediately. If a belt is
twisted, it may be possible to untwist byreversing the latch plate on the webbing.
If the twist cannot be corrected, ask your
dealer to fix it.
Make sure the seat belt reminder light is
working. See
Seat Belt Reminders 081.
Keep seat belts clean and dry. See Seat Belt
Care 044.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly cared for and
maintained.
Seat belt hardware should be kept dry and
free of dust or debris. As necessary, exterior
hard surfaces and seat belt webbing may be
lightly cleaned with mild soap and water.
Ensure there is not excessive dust or debris
in the mechanism. If dust or debris exists in
the system please see the dealer. Parts may
need to be replaced to ensure proper
functionality of the system.
{Warning
Do not bleach or dye seat belt webbing.
It may severely weaken the webbing. In
a crash, they might not be able to

provide adequate protection. Clean and
rinse seat belt webbing only with mild
soap and lukewarm water. Allow the
webbing to dry.
Replacing Seat Belt System Parts
after a Crash
{Warning
A crash can damage the seat belt system
in the vehicle. A damaged seat belt
system may not properly protect the
person using it, resulting in serious injury
or even death in a crash. To help make
sure the seat belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as possible.
After a minor crash, replacement of seat
belts may not be necessary. But the seat
belt assemblies that were used during any
crash may have been stressed or damaged.
See your dealer to have the seat belt
assemblies inspected or replaced.
