Power Sounder, Inclination
Sensor, and Intrusion Sensor
In addition to the standard
theft-deterrent system features, this
system may also have a power
sounder, inclination sensor, and
intrusion sensor.
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 a change in vehicle
orientation.
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
sunshades.
. Make sure there are no
obstructions blocking the sensors
in the front overhead console.
Inclination and Intrusion
Sensors Disable Switch
It is recommended that the intrusion
and inclination sensors be deactivated
if pets are left in the vehicle or if the
vehicle is being transported.

Immobilizer
SeeRadio Frequency Statement 0386.
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 started
or the ignition is 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 the
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.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and
the RKE transmitter appears to be undamaged, try another transmitter.
Or, you may try placing the
transmitter in the transmitter pocket
located in the center console. See
Remote Keyless Entry (RKE) System
Operation
010.
If the ignition modes will not change
with the other transmitter or with the
transmitter in the transmitter pocket,
your vehicle needs service. If the
ignition does change modes, the first
transmitter may be faulty. See your
dealer.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see “Programming
Transmitters to the Vehicle ”under
Remote Keyless Entry (RKE) System
Operation 010.
Do not leave the transmitter or device
that disarms or deactivates the
theft-deterrent system in the vehicle.
