KEYS, DOORS, AND WINDOWS 27
The power sounder provides an
audible alarm which is distinct from
the vehicle’s horn. It has its own
power source, and can sound an alarm
if the vehicle’s battery is
compromised.
The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as when a tire is
removed. Make sure the vehicle's
alarm is not armed prior to any
jacking.
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
sensor:
.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.
. Close DVD screens before leaving
the vehicle.
Inclination and Intrusion Sensor
Disable Switch
It is recommended that the intrusion
and inclination sensor be deactivated
if pets are left in the vehicle or the
vehicle is being transported. With the
vehicle turned off, press
oin the
front overhead console. The indicator
light will come on momentarily, indicating that these sensors have
been disabled for the next alarm
system arming cycle.
Steering Column Lock
If equipped, the steering column lock
is a theft-deterrent device. This
feature locks the steering column
when the vehicle is turned off and the
driver door is opened, or when the
driver door is opened and then the
vehicle is turned off. The steering
column unlocks when the vehicle is
turned on.
The Driver Information Center (DIC)
may display one of these messages:
.
A message to service the steering
column lock indicates that an
issue has been detected with the
column lock feature and the
vehicle should be serviced.
. A message that the steering
column is locked indicates that
the engine is running, but the
steering column is still locked. It is
normal for the column to be
locked during a remote start, but
the column should unlock after

the brake pedal is pressed and the
vehicle is started. No message will
display during a remote start.
. A message that the steering wheel
must be turned and the vehicle
must be started again indicates
that the column lock mechanism
is bound, the column locking
device was unable to unlock the
steering column, and the vehicle
did not start. If this happens,
immediately turn the steering
wheel from side to side to unbind
the column lock. If this does not
unlock the steering column, turn
the vehicle off and open the driver
door to reset the system. Then
turn the vehicle on and
immediately turn the steering
wheel side to side for about
15 seconds. In some cases, it may
take significant force to unbind
the column.
To keep the steering column from
binding, straighten the front wheels
before turning off the vehicle.Immobilizer
See Radio Frequency Statement 0334.
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
08.
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.

56 SEATS AND RESTRAINTS
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. SeeHow to Wear Seat Belts
Properly 051.
Press the release button and move the
height adjuster to the desired position.
The adjuster can be moved up by pushing the slide/trim up. After the
adjuster is set to the desired position,
try to move it down without pressing
the release button to make sure it has
locked into position.
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 the
seat 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 0183.
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

Seat Belt System Parts after a Crash
