7. Once the transmitter is programmed, a beep will
sound. The DIC will display READY FOR X,
where X can be 3 or 4, or MAX # FOBS LEARNED.
8. Remove the transmitter from the transmitter pocket
and press the unlock button on the keyless access
transmitter two times.
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 into the
transmitter pocket with the transmitter buttons facing
the front of the vehicle. The transmitter pocket is
inside the center console storage area located
between the driver and front passenger seats.
3. Insert the vehicle key into the key lock cylinder
located on the driver’s door.

Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than

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 OFF/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.
2-26

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 3-80for additional information. At this time,
you may also want to check the fuse. SeeFuses and
Circuit Breakers on page 5-117. 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.Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer (Vehicles With Heavy Duty Cooling) on
page 4-34orTowing a Trailer (Vehicles Without
Heavy Duty Cooling) on page 4-40for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
