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 Remote
Keyless Entry (RKE) transmitter
leaves the vehicle.
The immobilization system is
disarmed when the ignition is turned
on or in ACC/ACCESSORY and a
valid RKE transmitter is 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 the 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 ignition will not change from
off to on or ACC/ACCESSORY, and
the RKE transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the cupholder in the
center console. See Remote
Keyless Entry (RKE) System
Operation 08. If the vehicle will not start with the
other transmitter, or with the
transmitter in the cupholder, the
vehicle needs service. If the vehicle
does start, the first transmitter may
be faulty. See your dealer who can
service the theft-deterrent system
and have a new RKE transmitter
programmed to the vehicle.
It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed to
the vehicle. To program additional
transmitters, see
“Programming
Transmitters to the Vehicle” under
Remote Keyless Entry (RKE)
System Operation 08.
Do not leave the transmitter or
device that disarms or deactivates
the theft-deterrent system in the
vehicle.

The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference
to the Keyless Access system. See
Remote Keyless Entry (RKE)
System Operation08.
