In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur
from the right front passenger airbag.
Airbags are designed to inate only once.
After an airbag inates, you will need some
new parts for the airbag system. If you do not
get them, the airbag system will not be there
to help protect you in another crash. A new
system will include airbag modules and
possibly other parts. The service manual
for your vehicle covers the need to replace
other parts.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection
and Event Data Recorders on page 468.
Let only qualied technicians work on your
airbag system. Improper service can mean
that your airbag system will not work properly.
See your dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system.
The passenger airbag status indicator on the
instrument panel will be visible when you turn your
ignition key to ON or START. The words ON
and OFF or the symbol for on and off, will
be visible during the system check.
When the system check is complete, either the
word ON or the word OFF, or the symbol for on or
the symbol for off will be visible. SeePassenger
Airbag Status Indicator on page 182.
The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.

{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag system.
If this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front
passenger’s seat may not have the
protection of the frontal airbag. See
Airbag Readiness Light on page 181for
more on this, including important safety
information.Aftermarket equipment, such as seat covers, can
affect how well the passenger sensing system
operates. You may want to consider not using
seat covers or other aftermarket equipment if
your vehicle has the passenger sensing system.
SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 93for more information about
modications that can affect how the system
operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
91

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system
in several places around your vehicle. You do not
want the system to inate while someone is
working on your vehicle. Your dealer and the
service manual have information about servicing
your vehicle and the airbag system. To purchase
a service manual, seeService Publications
Ordering Information on page 475.
{CAUTION:
For up to 10 seconds, after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are
close to an airbag when it inates. Avoid
yellow connectors. They are probably part
of the airbag system. Be sure to follow
proper service procedures, and make sure
the person performing work for you is
qualied to do so.
The airbag system does not need regular
maintenance.
92

Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
At times you may notice a decrease in range. This
is normal for any RKE system. If the transmitter
does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far
from your vehicle. You may need to stand
closer during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement
is necessary. See “Battery Replacement”
underRemote Keyless Entry (RKE) System
Operation on page 101.
If you are still having trouble, see your dealer
or a qualied technician for service.
Remote Keyless Entry (RKE)
System Operation
If your vehicle has this feature you can lock
and unlock your doors and disarm or arm your
theft-deterrent system from about 3 feet (1 m) up
to 30 feet (9 m) away using the remote keyless
entry transmitter. SeeContent Theft-Deterrent
on page 112for additional information.
UNLOCK:Press this
button to unlock the
driver’s door and turn
on the interior lamps.
The parking lamps may
also ash, and the
horn may chirp, when
this button is pressed.
Press the unlock button again within
three seconds and all of the doors will unlock.
101

If the alarm does not sound when it should but the
lights ash, check to see if the horn works. The
horn fuse may be blown. To replace the fuse, see
Fuses and Circuit Breakers on page 426.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer for service.
Passlock®
Your vehicle has the Passlock®theft-deterrent
system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If an incorrect key is used or
the ignition lock cylinder is tampered with, the fuel
system is disabled and the vehicle will not start.
During normal operation, the security light will turn
off approximately ve seconds after the engine
is started. SeeSecurity Light on page 192.If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.
If the engine does not start after three tries, the
vehicle needs service.
If the engine is running and the security light
comes on, you will be able to restart the engine if
you turn the engine off. However, your Passlock
®
system is not working properly and must be
serviced by your dealer. Your vehicle is not
protected by Passlock
®at this time. See your
dealer for service.
In an emergency, call the Roadside Assistance
Center. SeeRoadside Assistance Program
on page 462.

Ignition Positions
With the key in the
ignition switch, you can
turn to four different
positions.
LOCK (A):This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. It will locks the steering wheel on
manual transmission vehicles when the key is
removed. It is a theft-deterrent feature. You
will only be able to remove your key when the
ignition is turned to LOCK.
If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the
shift lever is in PARK (P).Notice:Using a tool to force the key from the
ignition switch could cause damage or break
the key. Use the correct key and turn the key
only with your hand. Make sure the key is all the
way in. If it is, turn the steering wheel left and
right while you turn the key hard. If none of this
works, then your vehicle needs service.
ACC (ACCESSORY) (B):This is the position in
which you can operate your electrical accessories
or items plugged into the accessory power
outlets. On automatic transmission vehicles,
this position unlocks the ignition. On manual
transmission vehicles, it unlocks the ignition and
steering wheel. Use this position if your vehicle
must be pushed or towed.
ON (C):This is the position that the switch
returns to after you start your engine and release
the switch. The switch stays in ON when the
engine is running. But even when the engine is
not running, you can use ON to operate the
electrical accessories and to display some
instrument panel cluster warning and indicator
lights. The transmission is also unlocked in
this position on automatic transmission vehicles.
116

Use these buttons to shift into and out of four-wheel
drive. You can choose from the following:
2
m(Two-Wheel High):This setting is for driving
in most street and highway situations. Your front
axle is not engaged in two-wheel drive.
{CAUTION:
Shifting the transfer case to NEUTRAL
can cause your vehicle to roll even if the
transmission is in PARK (P), or if you
have a manual transmission, even if you
are in gear. You or someone else could
be seriously injured. Be sure to set the
parking brake before placing the transfer
case in NEUTRAL. SeeParking Brake
on page 130.
N (NEUTRAL):Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle.4
m(Four-Wheel High):This setting engages
your front axle to help drive your vehicle. Use
four-wheel high when you need extra traction, such
as on snowy or icy roads, or in most off-road
situations.
4
n(Four-Wheel Low):This setting also
engages your front axle to give you extra traction.
It sends the maximum power to all four wheels.
You might choose four-wheel low if you were
driving off-road in sand, mud, or deep snow and
while climbing or descending steep hills.
Indicator lights in the buttons show you which
setting you are in. The indicator lights will come on
briey when you turn on the ignition and one will
stay on the selected setting. If the lights do
not come on, you should take your vehicle in for
service. An indicator light will ash while shifting.
It will stay on when the shift is completed.
If for some reason the transfer case does not shift,
it will return to the last chosen setting.
