what to do to avoid or reduce the
hazard. Read these cautions.
A notice tells about something that
can damage the vehicle.
Notice:These mean there is
something that could damage

The notice tells what to do to help
avoid the damage.
There are also warning labels on
the vehicle which use the same
words, CAUTION or Notice.

iv Preface

The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deated
airbags. Airbag ination does not
prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
{CAUTION
When an airbag inates, there may
be dust in the air. This dust could
cause breathing problems for
people with a history of asthma or
other breathing trouble. To avoid
this, everyone in the vehicle should
get out as soon as it is safe to do
so. If you have breathing problems
(Continued)
CAUTION (Continued)
but cannot get out of the vehicle
after an airbag inates, then get
fresh air by opening a window or
a door. If you experience
breathing problems following an
airbag deployment, you should
seek medical attention.
The vehicle has a feature that may
automatically unlock the doors,
turn the interior lamps on, and turn
the hazard warning ashers on
when the airbags inate. You can
lock the doors, turn the interior
lamps off, and turn the hazard
warning ashers off by using the
controls for those features.
In many crashes severe enough to
inate the 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.
The vehicle has a crash sensing
and diagnostic module which
records information after a crash.
SeeVehicle Data Recording and
Privacy on page 7-16andEvent
Data Recorders on page 7-16.
Let only qualied technicians work
on the airbag systems. Improper
service can mean that an airbag
system will not work properly. See
your dealer/retailer for service.

Ignition Positions
The ignition switch has four different
positions.
To shift out of P (Park), turn the
ignition to ON/RUN and apply
the regular brake pedal.Notice:Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct key,
make sure it is all the way in, and
turn it only with your hand. If the
key cannot be turned by hand, see
your dealer/retailer.
(A) LOCK/OFF:This position
locks the ignition. It also locks
the transmission on automatic
transmission vehicles. It locks
the steering wheel on manual
transmission vehicles. The key can
only be removed in LOCK/OFF.
On vehicles with an automatic
transmission, the shift lever must be
in P (Park) to turn the ignition
switch to LOCK/OFF.
The steering can bind with the
wheels turned off center. If this
happens, move the steering wheel
from right to left while turningthe key to ACC/ACCESSORY.
If this doesn’t work, then the vehicle
needs service.
(B) ACC/ACCESSORY:This is the
position in which you can operate
the 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 the vehicle must be pushed or
towed.
(C) ON/RUN:This position can be
used to operate the electrical
accessories and to display some
instrument panel cluster warning
and indicator lights. The switch stays
in this position when the engine is
running. The transmission is
also unlocked in this position on
automatic transmission vehicles.
2-16 Features and Controls

If you leave the key in the
ACC/ACCESSORY or ON/RUN
position with the engine off,
the battery could be drained.

Notice:Shifting the transmission
into gear before the indicator
light stops ashing could cause
damage to the transfer case.

light stops ashing before putting
the transmission back in gear.
To shift into Four-Wheel-Low Lock,
the ignition must be in ON/RUN
and the vehicle must be stopped or
moving less than 3 mph (5 km/h)
with the transmission in N (Neutral).
The preferred method for shifting
into Four-Wheel Low is to have

engagement noise and bump
when shifting between Four-Wheel
Low and Four-Wheel High ranges
or from Neutral.
