without starting the vehicle; the key is
learned and all previously known keys
will no longer work with the vehicle.
6. To program the second key, turn the ignition off and insert the second key to
be learned and turn the ignition on
without starting the vehicle.
After the two keys are learned, remaining
keys can be learned by following the
procedure in “Programming with Two
Recognized Keys.”

more information.
Immobilizer
See Radio Frequency Statement 0248.
Immobilizer Operation (Key
Access)
This vehicle has a passive 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 an
authorized key starts the vehicle. The vehicle
may 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. When trying to start the vehicle, the
security light comes on briefly when the
ignition is turned on.
If the engine does not start and the 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 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.

other vehicles, look farther away than
they really are. If you cut too sharply
into the right lane, you could hit a (Continued)

vehicle on the right. Check the inside
mirror or glance over your shoulder
before changing lanes.
The passenger side mirror is convex shaped.

Warning
With head restraints that are not
installed and adjusted properly, there is a
greater chance that occupants will suffer
a neck/spinal injury in a crash. Do not
drive until the head restraints for all
occupants are installed and adjusted
properly.
Adjust the head restraint so that the top of
the restraint is at the same height as the
top of the occupant's head. This position
reduces the chances of a neck injury in a
crash.

0 50. If this occurs, let the belt go back
all the way and start again. If the
locking feature stays engaged after
letting the belt go back to stowed
position on the seat, move the seat
rearward or recline the seat until the
shoulder belt retractor lock releases.
Engaging the child restraint locking
feature in the front outboard seating
position may affect the passenger
sensing system. See Passenger Sensing
System 042.
If the webbing locks in the latch plate
before it reaches the buckle, tilt the latch
plate to flat to unlock.
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 Seat Belt Extender 035.
Position the release button on the buckle
so that the seat belt could be quickly
unbuckled if necessary.4. To make the lap part tight, pull up on the shoulder belt.

36 Seats and Restraints
But if a seat 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 restraints. For
more information on the proper use and fit
of seat belt extenders see the instruction
sheet that comes with the extender.
Safety System Check
Periodically check the seat belt reminder,
seat belts, buckles, latch plates, retractors,
shoulder belt height adjusters (if equipped),
and seat belt anchorages to make sure they
are all in working order. Look for any other
loose or damaged seat belt system parts
that might keep a seat belt system from
performing properly. See your dealer to
have it repaired. Torn, frayed, or twisted
seat belts may not protect you in a crash.
Torn or frayed seat belts can rip apart under
impact forces. If a belt is torn or frayed,
have it replaced immediately. If a belt is
twisted, it may be possible to untwist byreversing the latch plate on the webbing.
If the twist cannot be corrected, ask your
dealer to fix it.
Make sure the seat belt reminder light is
working. See
Seat Belt Reminders 073.
Keep seat belts clean and dry. See Seat Belt
Care 036.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly cared for and
maintained.
Seat belt hardware should be kept dry and
free of dust or debris. As necessary, exterior
hard surfaces and seat belt webbing may be
lightly cleaned with mild soap and water.
Ensure there is not excessive dust or debris
in the mechanism. If dust or debris exists in
the system please see the dealer. Parts may
need to be replaced to ensure proper
functionality of the system.
{Warning
Do not bleach or dye seat belt webbing.
It may severely weaken the webbing. In
a crash, they might not be able to
(Continued)
Warning (Continued)
provide adequate protection. Clean and
rinse seat belt webbing only with mild
soap and lukewarm water. Allow the
webbing to dry.
Replacing Seat Belt System Parts
after a Crash
{Warning
A crash can damage the seat belt system
in the vehicle. A damaged seat 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 seat belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as possible.
After a minor crash, replacement of seat
belts may not be necessary. But the seat
belt assemblies that were used during any
crash may have been stressed or damaged.
See your dealer to have the seat belt
assemblies inspected or replaced.

38 Seats and Restraints
Warning (Continued)
unnecessarily close to any airbag, as you
would be if sitting on the edge of the
seat or leaning forward. Seat belts help
keep you in position before and during a
crash. Always wear a seat belt, even with
airbags. The driver should sit as far back
as possible while still maintaining control
of the vehicle. The seat 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 seat-mounted side
impact airbags and/or roof-rail airbags.
{Warning
Children who are up against, or very
close to, any airbag when it inflates can
be seriously injured or killed. Always
secure children properly in the vehicle. To
read how, seeOlder Children 047 or
Infants and Young Children 048.
There is an airbag readiness light on the
instrument cluster, 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 074.
Where Are the Airbags?
The driver frontal airbag is in the center of
the steering wheel. The front outboard passenger frontal airbag
is in the passenger side instrument panel.
The driver knee airbag is below the steering
column. The front outboard passenger knee
airbag is below the glove box.
