Remote Keyless Entry
(RKE) System
See Radio Frequency Statement on
page 13-11. If there is a decrease in the RKE
operating range:
.Check the distance. The
transmitter may be too far from
the vehicle.
.Check the location. Other
vehicles or objects may be
blocking the signal.
.Check the transmitter's battery.
See
“Battery Replacement” later
in this section.

2-18 Keys, Doors, and Windows
The inclination sensor can set off
the alarm if it senses movement of
the vehicle, such as a change in
vehicle orientation.
Immobilizer
SeeRadio Frequency Statement on
page 13-11.
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 pushbutton start
is activated to enter the ACC/
ACCESSORY mode or the ON/
RUN/START mode 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/
RUN/START, 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
Key and Lock Messages on
page 5-39.
If the ignition modes will not change
with the other transmitter, your
vehicle needs service. If the ignition
does change modes, the first
transmitter may be faulty. See your
dealer.
