The Canadian immobilizer standard requires Canadian
owners to see their dealer/retailer for matching new
transmitters when two recognized transmitters are not
available. United States owners are permitted to match a
new transmitter to their vehicle when a recognized
transmitter is not available. The procedure will require
three ten minute cycles to complete the matching
process. Do the following:
1. The vehicle must be off.
2. Place the new, unrecognized transmitter in the
glove box transmitter pocket with the buttons
facing to the right.3. Go to the rear of the vehicle and insert the vehicle
key into the key cylinder located on the lower
rear fascia on the driver’s side of the vehicle.
SeeTrunk on page 2-13for more information on

Immobilizer Operation
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition
mode transitions to OFF.
The immobilization system is disarmed when the ignition
mode transitions to ACCESSORY or START and a
valid transmitter is found in the vehicle.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
The system has one or more keyless access
transmitters that are matched to an immobilizer control
unit in your vehicle. Only a correctly matched keyless
access transmitter will start the vehicle. If the keyless
access transmitter is ever damaged, you may not
be able to start your vehicle.
When trying to start the vehicle, if the engine does
not start and the security light comes on, there may
be a problem with your immobilizer system. Press the
START button again.If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, you may try placing the
transmitter in the transmitter pocket. See “NO FOBS
DETECTED” underDIC Warnings and Messages
on page 3-63for additional information. At this time,
you may also want to check the fuse. SeeFuses
and Circuit Breakers on page 6-90. If the engine
still does not start with the other transmitter, your
vehicle needs service. If the engine does start, the
rst transmitter may be faulty. See your dealer/retailer
who can service the theft-deterrent system and
have a new keyless access transmitter programmed
to the vehicle.
It is possible for the immobilizer system to learn new or
replacement keyless access transmitters. Up to 4 keyless
access transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-6.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
