passenger door, side door, rear
door, or the hood is opened without

0 331.
Immobilizer Operation
This vehicle is equipped with the
PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent system. PASS-Key III
+ is a passive theft deterrent
system.
The system is automatically armed
when the key is removed from the
ignition.
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.
If the engine does not start and the
security light comes on, the key may
have a damaged transponder. Turn
the ignition off and try again.
If the engine still does not start, and
the key appears to be undamaged,
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 faulty. See your dealer or a
locksmith who can service the
PASS-Key III+ to have a new
key made.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to eight keys may be
programmed for the vehicle. This
procedure is for learning additional
keys only. If all the currently
programmed keys are lost or do not
operate, you must see your dealer
or a locksmith who can service
PASS-Key III+ to have keys made
and programmed to the system.
See your dealer or a locksmith who
can service PASS-Key III+ to get a
new key blank that is cut exactly as
the ignition key that operates the
system.
To program the new key:
1. Verify the new key has
1
stamped on it.
2. Insert the original, already programmed key into the
ignition lock cylinder and start
the engine. If the engine will
not start, see your dealer for
service.

3. After the engine has started,turn the ignition off and remove
the key.
4. Insert the key to be programmed and turn the
ignition on within 10 seconds of
removing the previous key.
The security message will turn
off once the key has been
programmed. It may not be
apparent that the security
message went on due to how
quickly the key is programmed.
5. Repeat Steps 1–4 if additional keys are to be programmed.
If you lose or damage a
PASS-Key III+ key, see your dealer
or a locksmith who can service
PASS-Key III+ to 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 next lane,
you could hit a vehicle that is
driving next to you. Check the
inside mirror or glance over your
shoulder before changing lanes.
If equipped, the lower portion of the
driver and passenger side mirror is
convex. A convex mirror's surface is
curved so more can be seen from
the driver seat. The convex mirror
can be adjusted manually to the
driver preferred position for better
vision.
Manual Mirrors
Adjust the mirrors by moving the
mirror up and down and left and
right. The mirrors can be manually folded
in or out.
On the lower portion of each mirror
is an auxiliary convex mirror.
A convex mirror's surface is curved
so you can see more from the driver
seat. The auxiliary convex mirrors
can be adjusted manually by
moving the mirror.
Trailer-Tow Mirrors
Vehicles with towing mirrors can be
adjusted manually for a clear view
of the objects behind you.
