In addition to the standard
theft-deterrent system features, this
system may also have a power
sounder, inclination sensor, and
intrusion sensor.

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

28 KEYS, DOORS, AND WINDOWS
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.

50 SEATS AND RESTRAINTS
Raising the Seatback
{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.
{Warning
A seat belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. After raising the
rear seatback, always check to be
sure that the seat belts are properly
routed and attached, and are not
twisted.To raise a seatback:
1. Lift the seatback up. Make sure the center seat belt and latch do
not get trapped behind the seat.
Push the seatback rearward to
lock it in place.
A red tab near the seatback lever
retracts when the seatback is
locked in place.
2. Push and pull the top of the seatback to be sure it is locked
into position.
3. Reconnect the center seat belt mini-latch to the mini-buckle. Do
not let the belt twist.
4. Pull on the center seat belt to make sure the mini-latch is
secure.
5. Repeat the steps to raise the other seatback, if necessary.
When the seat is not in use, it should
be kept in the upright, locked position.
Seat Belts
This section describes how to use seat
belts properly, and some things not
to do.
{Warning
Do not let anyone ride where a seat
belt cannot be worn properly. In a
crash, if you or your passenger(s)
are not wearing seat belts, injuries
can be much worse than if you are
wearing seat 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.
It is extremely dangerous to ride in
a cargo area, inside or outside of a
vehicle. In a collision, passengers
riding in these areas are more likely
to be seriously injured or killed. Do (Continued)
