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.

50 Seats and Restraints
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 thebuckle 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 055. Position the release button on
the buckle so that the seat belt
could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you.
See “Seat belt Height Adjuster”
later in this section for
instructions on use and
important safety information.
5. To make the lap part tight, pull
up on the shoulder belt. It may be necessary to pull
stitching on the seat belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
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

Seat Belt Extender
If the vehicle's seat belt will fasten
around you, you should use it.
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 aseat belt system from performing
properly. See your dealer to have it
repaired. Torn or frayed seat belts
may not protect you in a crash.
They can rip apart under impact
forces. If a belt is torn or frayed,
have it replaced immediately.
Make sure the seat belt reminder
light is working. See
Seat Belt
Reminders 0102.
Keep seat belts clean and dry. See
Seat Belt Care 055.
Seat Belt Care
Keep belts clean and dry.
{Warning
Do not bleach or dye seat belt
webbing. It may severely weaken
the webbing. In a crash, they
might not be able to provide
adequate protection. Clean and
rinse seat belt webbing only with
mild soap and lukewarm water.
Allow the webbing to 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.

System Parts after a
Crash

58 Seats and Restraints
{Warning
Because airbags inflate with great
force and faster than the blink of
an eye, anyone who is up
against, or very close to, any
airbag when it inflates can be
seriously injured or killed. Do not
sit 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.(Continued)
Warning (Continued)
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 068 or
Infants and Young Children 070.
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 0102.
Where Are the Airbags?
The driver frontal airbag is in the
center of the steering wheel.

11374212) - 2018 - crc - 2/2/18
60 Seats and Restraints
Driver Side Shown, PassengerSide Similar
If the vehicle has two seating rows,
roof-rail airbags for the driver, front
outboard passenger, and second
row outboard passengers are in the
ceiling above the side windows.
If the vehicle has three or more
seating rows, roof-rail airbags for
the driver, front outboard passenger,
and second and third row outboard
passengers are in the ceiling above
the side windows.
{Warning
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
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. See Airbag System
0 56. 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.

infant will suddenly become a
110 kg (240 lb) force on a person's
arms. An infant or child should be
secured in an appropriate
restraint.
{Warning
Children who are up against,

Warning (Continued)
or killed. Never put a rear-facing
child restraint in the front
outboard seat. Secure a
rear-facing child restraint in a rear
seat. It is also better to secure a
forward-facing child restraint in a
rear seat. If you must secure a
forward-facing child restraint in
the front outboard seat, always
move the front passenger seat as
far back as it will go.
Child restraints are devices used to
restrain, seat, or position children in
the vehicle and are sometimes
called child seats or car seats.
There are three basic types of
child restraints:
.Forward-facing child restraints
. Rearward-facing child restraints
. Belt-positioning booster seats
The proper child restraint for your
child depends on their size, weight,
and age, and also on whether the
child restraint is compatible with the
vehicle in which it will be used.
For each type of child restraint,
there are many different models
available. When purchasing a child
restraint, be sure it is designed to be
used in a motor vehicle. If it is, the
restraint will have a label saying that
it meets federal motor vehicle safety
standards. The restraint
manufacturer's instructions that
come with the restraint state the
weight and height limitations for a
particular child restraint. In addition,
