the Vehicle
Only RKE transmitters programmed
to the vehicle will work. If a
transmitter is lost or stolen, a
replacement can be purchased and
programmed through your dealer.
The vehicle can be reprogrammed
so that lost or stolen transmitters no
longer work. Any remaining
transmitters will need to be
reprogrammed. Each vehicle can
have up to eight transmitters
matched to it. Programming with a Recognized
Transmitter (Key Vehicles Only)
To program a new key:
1. Insert the original, already programmed key in the ignition
and turn the key to the ON/
RUN position.
2. Turn the key to LOCK/OFF, and remove the key.
3. Insert the new key to be programmed and turn it to the
ON/RUN position within
five seconds.
The security light will turn off
once the key has been
programmed.
4. Repeat Steps 1–3 if additional keys are to be programmed.
If a key is lost or damaged, see your
dealer to have a new key made.
Programming without a
Recognized Transmitter (Key
Vehicles Only)
Program a new key to the vehicle
when a recognized key is not
available. Canadian regulations
require that owners see their dealer. If there are no currently recognized
keys available, follow this procedure
to program the first key.
This procedure will take
approximately 30 minutes to
complete for the first key. The
vehicle must be off and all of the
keys you wish to program must be
with you.
1. Insert the new vehicle key into the ignition.
2. Turn to ON/RUN. The security light will come on.
3. Wait 10 minutes until the security light turns off.
4. Turn the ignition to LOCK/OFF.
5. Repeat Steps 2–4 two more times. After the third time, turn
to ON/RUN; the key is learned
and all previously known keys
will no longer work with the
vehicle.
Remaining keys can be learned by
following the procedure in
“Programming with a Recognized
Transmitter (Key Vehicles Only).”

theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the key is
removed from the ignition.
The system is automatically
disarmed when the vehicle is
started with the correct key. The key uses a transponder that matches an
immobilizer control unit in the
vehicle and automatically disarms
the system. Only the correct key

not start if the key is damaged.
The security light in the instrument
cluster comes on if there is a
problem with arming or disarming
the theft-deterrent system.

security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged
or the light continues to stay on, try
another ignition key.
If the engine still does not start with
the other key, the vehicle needs
service. If the vehicle does start, the
first key may be damaged. See your
dealer who can service the
theft-deterrent system and have a
new key made.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.

Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.
