Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are part of the safety belt
assembly. They help tighten the safety belts during
the early stages of a moderate to severe frontal
or near frontal crash if the threshold conditions for
pretensioner activation are met. And, if your
vehicle has roof-mounted rollover airbags, safety
belt pretensioners can help tighten the safety
belts in a side crash or a rollover event.
Pretensioners work only once. If they activate
in a crash, you will need to get new ones,
and probably other new parts for your safety belt
system. SeeReplacing Restraint System Parts
After a Crash on page 89.
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/retailer 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 t. 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.

Frontal airbags (driver and right front passenger)
are not intended to inate during vehicle
rollovers, rear impacts, or in many side impacts.
Your vehicle has seat position sensors which
enables the sensing system to monitor the position
of the driver’s seat and the right front passenger’s
seat. Seat position sensors provide information
that is used to determine if the airbags should
deploy at a reduced level or at full deployment.
Your vehicle may or may not have roof-mounted
airbags and a rollover sensor. SeeAirbag
System on page 69. These “rollover capable”
airbags are intended to inate in moderate to
severe side crashes or during a rollover.
A roof-mounted airbag will inate if the crash
severity is above the system’s designed “threshold
level.” The threshold level can vary with specic
vehicle design. Roof-mounted airbags are not
intended to inate in frontal or near-frontal impacts,
or rear impacts. Both roof-mounted airbags will
deploy when either side of the vehicle is struck or
during a rollover.In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair
costs were. For frontal airbags, ination is
determined by what the vehicle hits, the angle of
the impact, and how quickly the vehicle slows
down. For roof-mounted airbags, ination is
determined by the location and severity of
the impact.
The airbag system is designed to work properly
under a wide range of conditions, including off-road
usage. Observe safe driving speeds, especially
on rough terrain. As always, wear your safety belt.
SeeOff-Road Driving (Except SS) on page 323
for tips on off-road driving.

Passenger Sensing System
Your vehicle has a passenger sensing system for
the right front passenger’s position. A passenger
airbag status indicator in the rearview mirror will be
visible when you turn your ignition key to START
or RUN.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 203.
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.
The passenger sensing system works with
sensors that are part of the right front passenger’s
seat and safety belt. The sensors are designed
to detect the presence of a properly-seated
occupant and determine if the passenger’s frontal
airbag should be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding in
a rear-facing infant seat, a child riding in a
forward-facing child seat, and an older child riding
in a booster seat.

the FIRST (1) position.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only
the accelerator pedal may damage the
transmission. The repair will not be covered by
your warranty. If you are stuck, do not spin
the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
Four-Wheel Drive
If your vehicle has four-wheel drive, the engine’s
driving power can be sent to all four wheels
for extra traction. To get the most satisfaction out
of four-wheel drive, you must be familiar with
its operation. Read the part that follows before
using four-wheel drive. You should use Two-Wheel
High for most normal driving conditions.Notice:Driving on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive
Low for an extended period of time may cause
premature wear on your vehicle’s powertrain.
Do not drive on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive
Low for extended periods of time.
Notice:If you continually drive your vehicle
with the transfer case in AUTO or Four-Wheel
Drive, you could shorten the life of the
transfer case or the Four-Wheel Drive system.
The selector switch should be left in
Two-Wheel Drive High mode. Only use AUTO
and Four-Wheel Drive when you need extra
traction such as in wet or slippery road
conditions.

To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of
the air to the instrument panel outlets; then directs
most of the remaining air to the oor outlets. A little
air is directed toward the windshield and the side
window outlets. Cooler air is directed to the upper
vents and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with a little air directed to the windshield
and the side window outlets. The recirculation
button cannot be selected while in oor mode.
@(Recirculation):Recirculation mode is used
to recirculate the air inside of your vehicle. When
this button is pressed, an indicator light in the
button will come on to let you know that it is active.
Use this mode to help prevent outside odors and/or
dust from entering your vehicle or to help cool the
air inside of your vehicle more quickly. The air
conditioning compressor will also come on when
this mode is activated. While in recirculation mode,the windows may fog when the weather is cold and
damp. To clear the fog, select either the defog or
defrost mode and increase fan speed.
Defog and defrost modes are described later in this
section.
Driver’s Side Temperature Lever:The lever on
the left side of the climate control panel is
used to raise or lower the temperature on the
driver’s side of the vehicle. Slide the lever up or
down to adjust the temperature.
Passenger’s Side Temperature Lever:The lever
on the right side of the climate control panel is
used to raise or lower the temperature on the
passenger’s side of the vehicle. Slide the lever up
or down to adjust the temperature. This lever also
adjusts the temperature to the rear seat outlets.
When the temperature outside is 0°F (-18°C) or
lower, use the engine coolant heater, if the vehicle
has one, to provide warmer air, faster to your
vehicle.
#(Air Conditioning):Press this button to turn
the air-conditioning system on or off. When the
button is pressed, an indicator light will come on
and the system will begin to cool and dehumidify
188

the air inside of the vehicle. You may notice a
slight change in engine performance when the
air conditioning compressor shuts off and turns
on again. This is normal.
Defogging and Defrosting
Fog on the inside of windows is a result of
high humidity (moisture) condensing on the
cool window glass. This can be minimized if the
climate control system is used properly. There
are two modes to choose from to clear fog or
frost from your windshield. Use the defog mode to
clear the windows of fog or moisture and warm
the passengers. Use the defrost mode to remove
fog or frost from the windshield more quickly.
Turn the right knob clockwise or counterclockwise
to select one of the following modes:
-(Defog):This mode directs the air to the
oor outlets, windshield and side window outlets.
The recirculation button cannot be selected
while in defog mode.
1(Defrost):This mode directs most of the
air to the windshield and the side window outlets,
with only a little air directed to the oor outlets.The air conditioning compressor may run to
dehumidify the air to prevent window fogging.
The recirculation button cannot be selected while
in defrost mode. Do not drive the vehicle until
all the windows are clear.
Rear Window Defogger
If your vehicle has the rear window defogger
a warming grid is used to remove fog on the
rear window.
<(Rear):Press this button to turn the rear
window defogger on or off. An indicator light in the
button will come on to let you know that the rear
window defogger is active. The rear window
defogger will automatically turn off approximately
ten minutes after the button is pressed.
If your vehicle has heated mirrors, this button will
activate them.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.

The passenger’s side temperature setting also
resets and relinks to the driver’s side temperature
setting if the vehicle has been off for more
than three hours.
Outside Air Temperature Display
A new outside temperature reading will be
displayed if the vehicle has been off for more
than three hours. If the vehicle has been off for
less than three hours, the old temperature
reading may be displayed because underhood
heat is affecting the true outside temperature.
Underhood heat can also affect the outside
temperature while the engine is running.
It may also take several minutes of driving
before the display updates to the actual
outside temperature.
Automatic Operation
AUTO (Automatic):When automatic operation
is active, the system will control the inside
temperature, the air delivery mode, and the
fan speed.Use the steps below to place the entire system
in automatic mode:
1. Press the AUTO button.
When AUTO is selected, the air conditioning
operation and air outlet mode will be
automatically controlled. The air conditioning
compressor will run continuously when the
outside temperature is over approximately
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet will
automatically switch to recirculate inside air to
help quickly cool down your vehicle.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a
72°F (22°C) temperature setting and allow
about 20 minutes for the system to adjust.
Turn the driver’s or passenger’s side
temperature knob to adjust the temperature
setting as necessary. If you choose the
temperature setting of 60°F (15°C), the system
will remain at the maximum cooling setting.
If you choose the temperature setting of
90°F (32°C), the system will remain at the
maximum heat setting. Choosing either
maximum setting may not cause the vehicle
to heat or cool any faster.
