Immobilizer
See Radio Frequency
Statement 0395.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to
be manually armed or
disarmed.
The vehicle is automatically
immobilized when the vehicle
is turned off. The immobilization system is
disarmed when the vehicle is
turned and a valid remote key
is present in the vehicle.
The security light, in the
instrument cluster, comes on if
there is a problem with arming
or disarming the

The system has one or more
remote keys matched to an
immobilizer control unit in the
vehicle. Only a correctly
matched remote key will start
the vehicle. If the remote key
is ever damaged, you may not
be able to start your vehicle.
When trying to start the
vehicle, the security light may
come on briefly.If the vehicle does not start
and the security light stays on,
there is a problem with the
system. Turn the vehicle off
and try again.
If the vehicle will not turn on or
off, and the remote key
appears to be undamaged, try
another remote key. Or, you
may try placing the remote key
in the backup location. See
Remote Key Operation
08.
If the vehicle will not turn on or
off with the other remote key
or in the backup location, the
vehicle needs service. If the
vehicle does turn on or off,,
the first remote key may be
faulty. See your dealer.
It is possible for the
immobilizer system to learn
new or replacement remote
keys. Up to eight remote keys
can be programmed for the
vehicle. To program additional
remote keys, see
“Programming Remote Keys to
the Vehicle” under Remote
Key Operation 08.

2. Pick up the latch plate andpull 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 the shoulder portion of a
passenger belt is pulled out
all the way, the child
restraint locking feature
may be engaged. See Child
Restraint Systems 077.
If this occurs, let the belt go back all the way and start
again. If the locking feature
stays engaged after letting
the belt go back to stowed
position on the seat, move
the seat rearward or recline
the seat until the shoulder
belt retractor lock releases.
If the webbing locks in the
latch plate before it reaches
the buckle, tilt the latch
plate flat to unlock.
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
Seat Belt Extender 058.

The best way to protect the
fetus is to protect the mother.
When a seat belt is worn
properly, it is more likely that
the fetus will not be hurt in a
crash. For pregnant women, as
for anyone, the key to making
seat belts effective is wearing
them properly.
Seat Belt Extender
If the vehicle's seat belt will
fasten around you, you should
use it.
But if a seat belt is not long
enough, your dealer will order
you an extender. Only a GM
dealer issued extender should
be used. 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 useand 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 by reversing 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
0112.
Keep seat belts clean and dry.
See Seat Belt Care 058.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.

vehicle. The seat belts and
the front outboard
passenger airbags are most
effective when you are
sitting well back and upright
in the seat with both feet on
the floor.
Occupants should not lean
on or sleep against the door
or side windows in seating
positions with seat-mounted
side impact airbags and/or
roof-rail airbags.
{Warning
Children who are up against,
or very close to, any airbag
when it inflates can be
seriously injured or killed.

There is an airbag readiness
light on the instrument cluster,
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 0112.
Where Are the
Airbags?
The driver frontal airbag is in
the center of the steering
wheel.
The front outboard passenger
frontal airbag is in the
passenger side instrument
panel.

Warning (Continued)
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.
Do not use seat accessories
that block the inflation path
of a seat-mounted side
impact airbag.
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.
When Should an
Airbag Inflate?
This vehicle is equipped with
airbags. See Airbag System
059. Airbags are designed to
inflate if the impact exceeds
the specific airbag system's
deployment threshold.
Deployment thresholds are
used to predict how severe a
crash is likely to be in time for
the airbags to inflate and help
restrain the occupants. The
vehicle has electronic sensors
that help the airbag system
determine the severity of the
impact. Deployment
thresholds can vary with
specific vehicle design.
Frontal airbags are designed
to inflate in moderate to
severe frontal crashes to help
reduce the potential for
severe injuries, mainly to the
driver's or front outboard
passenger's head and chest. Whether the frontal airbags
will or should inflate is not
based primarily on how fast
the vehicle is traveling.
It depends on what is hit, the
direction of the impact, and
how quickly the vehicle
slows down.
Frontal airbags may inflate at
different crash speeds
depending on whether the
vehicle hits an object straight
on or at an angle, and whether
the object is fixed or moving,
rigid or deformable, narrow
or wide.
Frontal airbags are not
intended to inflate during
vehicle rollovers, in rear
impacts, or in many side
impacts.
In addition, the vehicle has
advanced technology frontal
airbags. Advanced technology
frontal airbags adjust the
restraint according to crash
severity.
