Power Sounder, Inclination
Sensor, and Intrusion Sensor
In addition to the standard
theft-deterrent system features, this
system may also have an inclination
sensor, an intrusion sensor, and power
sounder. The power sounder provides an
audible alarm that is different from
the vehicle’s horn. It has its own
power source, and can sound an alarm
when the vehicle’s battery is
compromised.
The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as a change in vehicle
orientation.
The intrusion sensor monitors the
vehicle interior, and can set off the
alarm if it senses an 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 a
sunshades.
.Make sure there are no obstructions
blocking the sensors in the front
overhead console.

and intrusion sensors be deactivated if
pets are left in the vehicle or if the
vehicle is being transported.

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 thesystem. Then turn the vehicle on

Immobilizer
See Radio Frequency Statement 0406.
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 on or in
ACC/ACCESSORY and a valid
transmitter 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 RKE
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched RKE
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 may come 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.

adjuster for the driver and front
outboard passenger seating positions.
Adjust the height so that the shoulder
portion of the belt is on the shoulder
and not falling off of it. The belt

Warning (Continued)
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.
SeeAirbag System 061. 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 or near
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.
Knee airbags are designed to inflate in
moderate to severe frontal or near
frontal impacts. Knee airbags are not
designed to inflate during vehicle
rollovers, in rear impacts, or in many
side impacts.
Seat-mounted side impact airbags are
designed to inflate in moderate to
severe side crashes, depending on the
location of the impact. These airbags
are also designed to inflate in some
moderate to severe frontal or
near-frontal impacts that could result
in the occupant moving toward the
side of the vehicle. Seat-mounted side
impact airbags are not designed to
inflate in rollovers, or rear impacts.
A seat-mounted side impact airbag is
designed to inflate on the side of the
vehicle that is struck.
Roof-rail airbags are designed to
inflate in moderate to severe side
crashes depending on the location of
the impact. In addition, these roof-rail
airbags are designed to inflate during
