To open the driver side rear door,

Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
the vehicle impossible to steal.
Immobilizer
SeeRadio Frequency Statement on
page 13-12.
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. When the PASS-Key III+ system
senses that someone is using the
wrong key, it shuts down the
vehicle's starter and fuel systems.
The starter will not work and fuel will
stop being delivered to the engine.
Anyone using a trial-and-error
method to start the vehicle will be
discouraged because of the high
number of electrical key codes.
If the engine does not start and the
security message 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.

2-12 Keys, Doors, and Windows
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 key to LOCK/OFF and
remove the key.
4. Insert the key to be programmed and turn it to ON/RUN 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 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.
Manual Mirrors
Adjust the mirrors by pressing the
mirror up and down and left and
right.
The mirrors can be manually folded
in or out.

.Wear the shoulder belt over the
shoulder and across the chest.
These parts of the body are best
able to take belt restraining
forces. The shoulder belt locks if
there is a sudden stop or crash.
{Warning
You can be seriously injured,
or even killed, by not wearing
your safety belt properly.
.Never allow the lap or
shoulder belt to become
loose or twisted.
.Never wear the shoulder belt
under both arms or behind
your back.
.Never route the lap or
shoulder belt over an
armrest.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt. If you are
using a rear seating position with adetachable safety belt and the
safety belt is not attached, see
“Reinstalling the Rear Seats”
under
Rear Seats on page 3-4 for
instructions on reconnecting the
safety belt to the mini-buckle.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index.
2. Pick up the latch plate and pull the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
3. Push the latch plate into the
buckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3-15.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.

The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. See the instruction sheet that
comes with the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your dealer
to have it repaired. Torn or frayed
safety belts may not protect you in a
crash. They can rip apart under
impact forces. If a belt is torn or
frayed, get a new one right away.
Make sure the safety belt reminder
light is working. SeeSafety Belt
Reminders on page 5-14.
Keep safety belts clean and dry.
See Safety Belt Care on page 3-15.
Safety Belt Care
Keep belts clean and dry.
{Warning
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able to
provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
Replacing Safety Belt
System Parts after a
Crash
{Warning
A crash can damage the safety
belt system in the vehicle.
A damaged safety belt system
may not properly protect the
person using it, resulting in
serious injury or even death in a
crash. To help make sure the
safety belt systems are working
properly after a crash, have them

position before and during a
crash. Always wear your safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle. The safety belts and
the front outboard passenger
airbags are most effective when
you are sitting well back and
upright in the seat with both feet
on the floor.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
roof-rail airbags.

Children who are up against,

it inflates can be seriously injured(Continued)

or killed. Always secure children
properly in the vehicle. To read
how, seeOlder Children on
page 3-28 orInfants and Young
Children on page 3-30.
There is an airbag readiness light
on the instrument panel, which
shows the airbag symbol.
The system checks the airbag
electrical system for malfunctions.
The light tells you if there is an
electrical problem. See Airbag
Readiness Light on page 5-15.
Where Are the Airbags?
The driver frontal airbag is in the
center of the steering wheel.
