{Warning
If the key is unintentionally rotated while
the vehicle is running, the ignition could
be moved out of the RUN position. This
could be caused by heavy items hanging
from the key ring, or by large or long
items attached to the key ring that could
be contacted by the driver or steering
wheel. If the ignition moves out of the
RUN position, the engine will shut off,
braking and steering power assist may be
impacted, and airbags may not deploy.
To reduce the risk of unintentional
rotation of the ignition key, do not
change the way the ignition key and
Remote Keyless Entry (RKE) transmitter,
if equipped, are connected to the
provided key rings.
The ignition key and key rings, and RKE
transmitter, if equipped, are designed to
work together as a system to reduce the
risk of unintentionally moving the key out
of the RUN position. The ignition key has a
small hole to allow attachment of the
provided key ring. It is important that any replacement ignition keys have a small hole.
See your dealer if a replacement key is
required.
The combination and size of the rings that
came with your keys were specifically
selected for your vehicle. The rings are
connected to the key like two links of a
chain to reduce the risk of unintentionally
moving the key out of the RUN position. Do
not add any additional items to the ring
attached to the ignition key. Attach
additional items only to the second ring,
and limit added items to a few essential
keys or small, light items no larger than an
RKE transmitter.
Interference from radio-frequency
identification (RFID) tags may prevent the
key from starting the vehicle. Keep RFID
tags away from the key when starting the
vehicle.
The key is used for the ignition, and all
locks.
See your dealer if a replacement key or
additional key is needed.
If it becomes difficult to turn a key, inspect
the key blade for debris. Periodically clean
with a brush or pick.
If locked out of the vehicle, see
Roadside
Assistance Program 0256.

Immobilizer
See Radio Frequency Statement 0260.
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
1stamped
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.
