The security light, located in the
instrument panel 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,
try another ignition key.
If the engine still does not start and
the light continues to stay on, try
another 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 damaged. See your
dealer who can service the
theft-deterrent system and have a
new key made.
It is possible for the theft-deterrent
system decoder to learn the
transponder value of a new or
replacement key. Up to 10 keys can
be programmed for the vehicle. The
following procedure is for
programming additional keys only.
To program a new key do the
following:
1. Verify that the new key has
1
stamped on it.
2. Insert the current key in the ignition 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
five seconds of the ignition being
turned to LOCK/OFF in Step 3.
5. The security light will turn off once the key has been
programmed. It may not be
apparent that the security light
went on due to how quickly the
key is programmed.
6. Repeat the Steps 1 through 4 if additional keys are to be
programmed.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.

Immobilizer Operation
(Keyless 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 ignition
control knob is turned to LOCK/OFF.
The immobilization system is
disarmed when the ignition control
knob is pushed in and a valid
transmitter is found in the vehicle.
The security light, located in the
instrument panel cluster, comes on
if there is a problem with arming or
disarming the theft-deterrent
system.The system has one or more
keyless access transmitters that are
matched to an immobilizer control
unit in your vehicle. Only a correctly
matched keyless access transmitter
will start the vehicle. If the keyless
access transmitter is ever damaged,
you may not be able to start your
vehicle.
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 control knob off and try
again.
If the ignition control knob does not
rotate, and the keyless access
transmitter appears to be
undamaged, try another keyless
access transmitter. Or, you may try
placing the transmitter in the
transmitter pocket located in the
center console. See
“Electronic Key
Not Detected” underKey and Lock
Messages on page 5‑36. If the ignition control knob still does
not rotate with the other transmitter,
the vehicle needs service. If the
ignition control knob does rotate, the
first transmitter may be faulty. See
your dealer who can service the
theft-deterrent system and have a
new keyless access transmitter
programmed to the vehicle.
It is possible for the immobilizer
system to learn new or replacement
keyless access transmitters. Up to
4 keyless access transmitters can
be programmed for the vehicle. To
program additional transmitters, see
“Programming Transmitters to the
Vehicle”
for Keyless Access under
Remote Keyless Entry (RKE)
System Operation (Key Access)
on
page 2‑5or Remote Keyless Entry
(RKE) System Operation (Keyless
Access) on page 2‑7.
Do not leave the key or device that
disarms or deactivates the theft
deterrent system in the vehicle.

{WARNING
You can be seriously injured by a
twisted belt. In a crash, you would
not have the full width of the belt
to spread impact forces. If a belt
is twisted, make it straight so it
can work properly, or ask your
dealer to fix it.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat isadjustable, 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 3‑28.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.

Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.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. For more information, 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 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. See
Safety Belt
Reminders
on page 5‑17for more
information.
Keep safety belts clean and dry.
See Safety Belt Care
on
page 3‑29.

{WARNING
Airbags inflate with great force,
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 the airbag, as you would
be if you were sitting on the edge
of your seat or leaning forward.
Safety belts help keep you in
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.
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. Airbags plus
lap-shoulder belts offer protection
for adults and older children, but
not for young children and infants.
Neither the vehicle's safety belt
system nor its airbag system is
designed for them. Young
children and infants need the
protection that a child restraint
system can provide. Always
secure children properly in your
vehicle. To read how, seeOlder
Children
on page 3‑44or Infants
and Young Children
on
page 3‑47
.
There is an airbag readiness light
on the instrument panel 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
on page 5‑17for more
information.

Driver Side shown, PassengerSide similar
The roof-rail airbags for the driver,
outboard front passenger, and
second 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?
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's or
outboard front passenger's head
and chest. However, they are only
designed to inflate if the impact
exceeds a predetermined
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.
Whether your frontal airbags will or
should deploy is not based on how
fast your vehicle is traveling.
It depends largely on what you hit,
the direction of the impact, and how
quickly your vehicle slows down.

.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. SeeVehicle Data
Recording and Privacy
on
page 13‑17and Event Data
Recorders on page 13‑17.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the outboard
front passenger position. The
passenger airbag status indicator
will be visible on the instrument
panel when the vehicle is started.
United States
Canada and Mexico
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. If the
vehicle has remote start, and it is
being used to start the vehicle from
a distance, you may not see the
system check. When the system
check is complete, either the word
ON or OFF, or the symbol for on or
off, will be visible. See Passenger
Airbag Status Indicator
on
page 5‑18. The passenger sensing system
turns off the outboard front
passenger frontal airbag under
certain conditions. The driver airbag,
seat‐mounted side impact airbags
and the roof-rail airbags are not
affected by the passenger sensing
system.
The passenger sensing system
works with sensors that are part of
the outboard front passenger seat.
The sensors are designed to detect
the presence of a properly-seated
occupant and determine if the
outboard front passenger frontal
airbag should be enabled (may
inflate) or not.
According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
