The intrusion sensor monitors the
vehicle interior, and can activate the
alarm if it senses unauthorized entry
into the vehicle's interior. Do not allow
passengers or pets to remain in the
vehicle when the intrusion sensor is
activated.
Before arming the theft-deterrent
system and activating the intrusion

.Make sure all doors and windows
are completely closed.
.Secure any loose items such as sun
glasses.
.Make sure there are no obstructions
blocking the sensors in the front
overhead console.

Immobilizer
See Radio Frequency Statement 0440.
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 ignition is turned
on or to ACC/ACCESSORY 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
theft-deterrent system.
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 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 vehicle will not change ignition
modes (ACC/ACCESSORY, on, 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 Keyless Entry (RKE) System
Operation
07.
If the ignition modes will not change
with the other remote key or in the
backup location, the vehicle needs
service. If the ignition does change
modes, 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 Keyless Entry
(RKE) System Operation 07.
Do not leave the remote key or device
that disarms or deactivates the
theft-deterrent system in the vehicle.

Automatic Seat Belt Tightening
System
The vehicle may have the Automatic
Seat Belt Tightening System.
Each time the vehicle is started with
the front seat belts buckled, the
system activates once to tighten theseat belts when the forward vehicle
speed exceeds the threshold for
activation.
The system also activates during
emergency braking and/or sudden
driving maneuvers and releases when
driving conditions return to normal.
The system will not activate if the
Traction Control/Electronic Stability
Control system is not functioning
properly. See
Traction Control/
Electronic Stability Control 0258.
If there is a problem with the
Automatic Seat Belt Tightening
System, a message displays on the
Driver Information Center (DIC). If a
system unavailable message displays
repeatedly or if a service message
displays, see your dealer. Other seat
belt functions are not affected by the
Automatic Seat Belt Tightening
System.Seat Belt Pretensioners
This vehicle has seat belt
pretensioners for the front outboard
occupants. Although the seat belt
pretensioners cannot be seen, they are
part of the seat belt assembly. They can help tighten the seat belts during
the early stages of a moderate to
severe frontal, near frontal, or rear
crash if the threshold conditions for
pretensioner activation are met. Seat
belt pretensioners can also help
tighten the seat belts in a side crash
or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash, the
pretensioners and probably other
parts of the vehicle's seat belt system
will need to be replaced. See
Replacing
Seat Belt System Parts after a Crash
0 55.
Do not sit on the outboard seat belt
while entering or exiting the vehicle or
at any time while sitting in the seat.
Sitting on the seat belt can damage
the webbing and hardware.
Rear Seat Belt Comfort Guides
Rear seat belt comfort guides may
provide added seat belt comfort for
older children who have outgrown
booster seats and for some adults.
When installed on a shoulder belt, the
comfort guide positions the shoulder
belt away from the neck and head.

SEATS AND RESTRAINTS 61
locked, the interior lamps can be
turned off, and the hazard warning
flashers can be turned off using the
controls for those features. If any of
these systems are damaged in the
crash they may not operate as normal.
{Warning
A crash severe enough to inflate the
airbags may have also damaged
important functions in the vehicle,
such as the fuel system, brake and
steering systems, etc. Even if the
vehicle appears to be drivable after
a moderate crash, there may be
concealed damage that could make
it difficult to safely operate the
vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
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 the
vehicle covers the need to replace
other parts.
.The vehicle has a crash sensing and
diagnostic module which records
information after a crash. See
Vehicle Data Recording and Privacy
0 442 and
Event Data Recorders 0442.
.Let only qualified technicians work
on the airbag system. Improper
service can mean that an airbag
system will not work properly. See
your dealer for service.
Passenger Sensing System
The vehicle has a passenger sensing
system for the front outboard
passenger position. The passenger
airbag status indicator will light on
the overhead console when the vehicle
is started.
The words ON and OFF, and the
symbols for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, and the symbol for
on or off, will be visible. See Passenger
Airbag Status Indicator 0105.
The passenger sensing system turns
off the front outboard passenger
frontal airbag and knee airbag under
certain conditions. No other airbag is
affected by the passenger sensing
system.
The passenger sensing system works
with sensors that are part of the front
outboard passenger seat and seat belt.
The sensors are designed to detect the
presence of a properly seated
occupant and determine if the front
outboard passenger frontal airbag and
knee airbag should be allowed to
inflate or not.
