not disarm the system or turn off the alarm.
How to Detect a Tamper Condition
IfKis pressed and the horn chirps and the
lights flash three times, the alarm was
activated while the alarm system was
armed.
If the alarm system has been activated, and
allowed to complete an event
(approximately one minute), a message will
appear on the Driver Information Center
(DIC) the next time the vehicle is started.

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

{Warning
A seat that is not locked into place
properly can move around in a collision
or sudden stop. People in the vehicle
could be injured. Be sure to lock the seat
into place properly when installing it.
{Warning
A seat belt that is improperly routed, not
properly attached, or twisted will not
provide the protection needed in a crash.
The person wearing the belt could be
seriously injured. After raising the rear
seatback, always check to be sure that
the seat belts are properly routed and
attached, and are not twisted. 1. Position the seat into the open slots in
both rails. Push the seat forward in the

32 Seats and Restraints
To unlatch the belt, push the button on the
buckle. The belt should return to its stowed
position. Slide the latch plate up the seat
belt webbing when the seat belt is not in
use. The latch plate should rest on the
stitching on the seat belt, near the guide
loop on the side wall.
Always stow the seat belt slowly. If the seat
belt webbing returns quickly to the stowed
position, the retractor may lock and cannot
be pulled out. If this happens, pull the seat
belt straight out firmly to unlock the
webbing, and then release it. If the webbing
is still locked in the retractor, see your
dealer.Before a door is closed, be sure the seat belt
is out of the way. If a door is slammed
against a seat belt, damage can occur to
both the seat belt and the vehicle.
Seat Belt Height Adjuster
The vehicle has a seat belt height adjuster
for the driver and front outboard passenger
positions.
Adjust the height so the shoulder portion of
the belt is on the shoulder and not falling
off of it. The belt should be close to, but not
contacting, the neck. Improper shoulder belt
height adjustment could reduce the
effectiveness of the seat belt in a crash. See
How to Wear Seat Belts Properly
029.
Squeeze both sides of the release button
and pull outward. Then move the height
adjuster up or down to the desired position
and release the button.
After the adjuster is set to the desired
position, try to move it up or down without
squeezing the release button to make sure it
has locked into position.
Seat Belt Pretensioners
If the vehicle has seat-mounted side impact
airbags and roof-rail airbags, it also has seat
belt pretensioners for the front outboard
occupants.
Although the seat belt pretensioners cannot
be seen, they are part of the seat belt
assembly. They can help tighten the seat
belts during the early stages of a moderate
to severe frontal, near frontal, or rear crash
if the threshold conditions for pretensioner
activation are met. And, if the vehicle has
roof-rail airbags, seat belt pretensioners can
help tighten the seat belts in a side crash or
a rollover event.

Warning (Continued)
that person causing severe injury or even
death. The path of an inflating airbag
must be kept clear. Do not put anything
between an occupant and an airbag, and
do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering.
Do not use seat accessories that block the
inflation path of a seat-mounted side
impact airbag.
Never secure anything to the roof of a
vehicle with roof-rail airbags by routing a
rope or tie‐down through any door or
window opening. If you do, the path of
an inflating roof-rail airbag will be
blocked.
When Should an Airbag Inflate?
This vehicle is equipped with one or more
airbags. SeeAirbag System 036. Airbags are
designed to inflate if the impact exceeds the
specific airbag system's deployment
threshold. Deployment thresholds are used
to predict how severe a crash is likely to be
in time for the airbags to inflate and help
restrain the occupants. The vehicle has electronic sensors which help the airbag
system determine the severity of the
impact. Deployment thresholds can vary
with specific vehicle design.
Frontal airbags are designed to inflate in
moderate to severe frontal or near-frontal
crashes to help reduce the potential for
severe injuries mainly to the driver or front
outboard passenger head and chest.
Whether the frontal airbags will or should
deploy is not based primarily on how fast
the vehicle is traveling. It depends largely
on what you hit, the direction of the
impact, and how quickly the vehicle
slows down.
Frontal airbags may inflate at different crash
speeds depending on whether the vehicle
hits an object straight on or at an angle,
and whether the object is fixed or moving,
rigid or deformable, narrow or wide.
Frontal airbags are not intended to inflate
during vehicle rollovers, rear impacts, or in
many side impacts.
Seat-mounted side impact airbags,
if equipped, are designed to inflate in
moderate to severe side crashes depending
on the location of the impact. Seat-mounted
side impact airbags are not designed to
inflate in frontal impacts, near-frontal
impacts, rollovers, or rear impacts.
A seat-mounted side impact airbag is
intended to inflate on the side of the vehicle
that is struck.
The vehicle may or may not be equipped
with roof-rail airbags. Roof-rail airbags are
designed to inflate in moderate to severe
side crashes depending on the location of
the impact. In addition, these roof-rail
airbags are designed to inflate during a
rollover. Roof-rail airbags are not designed
to inflate in frontal, near-frontal, or rear
impacts. All roof-rail airbags will inflate
when either side of the vehicle is struck or if
the sensing system predicts that the vehicle
is about to roll over on its side.
In any particular crash, no one can say
whether an airbag should have inflated
simply because of the vehicle damage or
repair costs.What Makes an Airbag Inflate?
In a deployment event, the sensing system
sends an electrical signal triggering a release
of gas from the inflator. Gas from the
inflator fills the airbag causing the bag to
