2-49
You can choose among four driving settings:
2HI: This setting is used for driving in most street
and highway situations. Your front axle is not engaged
in two
-wheel drive. This setting also provides the best
fuel economy.
AUTO 4WD: This setting is ideal for use when road
conditions are variable. When driving your vehicle in
AUTO 4WD, the front axle is engaged, but the vehicle's
power is sent to the rear wheels. When the vehicle
senses a loss of traction, the system will automatically
engage four
-wheel drive. Driving in this mode results in
slightly lower fuel economy than 2HI.4HI: Use 4HI when you need extra traction, such as
on snowy or icy roads or in most off
-road situations.
This setting also engages your front axle to help drive
your vehicle. This is the best setting to use when
plowing snow.
4LO: This setting also engages your front axle and
delivers extra torque. You may never need 4LO. It sends
maximum power to all four wheels. You might choose
4LO if you are driving off
-road in deep sand, deep mud,
deep snow and climbing or descending steep hills.
CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the transmission
is in PARK (P). You or someone else could be
seriously injured. Be sure to set the parking
brake before placing the transfer case in
NEUTRAL. See ªParking Brakeº in the Index.

2-52
Shifting Out of NEUTRAL
To shift out of NEUTRAL:
1. Set the parking brake and apply the regular
brake pedal.
2. Shift the transmission to NEUTRAL (N) and turn the
ignition to RUN with the engine off.
3. Press the button for the desired transfer case shift
position (2HI, 4HI, AUTO 4WD or 4LO).
4. After the transfer case has shifted out of NEUTRAL
the red light will go out.
5. You may start the engine and shift the transmission
to the desired position.Electronic Transfer Case (If Equipped)
If your four-wheel-drive vehicle has the electronic
transfer case, the transfer case switches are located to
the left of the instrument panel cluster.
Use these switches to shift into and out of four
-wheel
drive. You can choose among three driving settings:
2HI: This setting is for driving in most street and
highway situations. Your front axle is not engaged in
two
-wheel drive.

2-53
4HI: This setting engages your front axle to help
drive your vehicle. Use 4HI when you need extra
traction, such as on snowy or icy roads, or in most
off
-road situations.
4LO: This setting also engages your front axle to give
you extra traction. You may never need 4LO. It sends
the maximum power to all four wheels. You might
choose 4LO if you were driving off
-road in sand, mud
or deep snow and climbing or descending steep hills.
Indicator lights in the switches show you which setting
you are in. The indicator lights will come on briefly
when you turn on the ignition and the last chosen setting
will stay on. If the lights do not come on, you should
take your vehicle in for service. An indicator light will
flash while shifting. It will remain illuminated when the
shift is completed. If for some reason the transfer
cannot make a requested shift, it will return to the last
chosen setting.
CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the transmission
is in PARK (P). You or someone else could be
seriously injured. Be sure to set the parking
brake before placing the transfer case in
NEUTRAL. See ªParking Brakeº in the Index.
NEUTRAL: Shift the vehicle's transfer case to
NEUTRAL only when towing your vehicle. See
ªRecreational Vehicle Towingº or ªTowing Your
Vehicleº in the Index for more information.

QUADRASTEER
(4WS)
(If Equipped)
The QUADRASTEER System has a control and
diagnostic module that monitors and records current
system status and operational information.
If your vehicle is equipped with the 4 Wheel Steer
system it has the ability to steer the vehicle with all
four wheels.
Once the 4 Wheel Steer mode is selected, it is
recommended to leave the vehicle in this mode
at all times.
The 4WS system is equipped with three different
driving modes:

Two wheel steering (2WS)

Four wheel steering (4WS)

Four wheel steering with a trailer mode (4WS TOW)
The switch is located on the instrument panel.
2WS: In this mode the vehicle will operate like any
other vehicle with two wheel steering. If you want to use
2WS and your vehicle is not in this mode, press the 4
Wheel Steer button until the 2WS indicator, located to
the right of the 4 Wheel Steer button, lights up. If the
2WS indicator is flashing you will have to center the
steering wheel by turning it to the left or right.
If you want to use tire chains, the vehicle needs to be in
2WS mode.

2-57
4WS: In this mode all four wheels will help steer the
vehicle. If you want to use 4WS, and your vehicle is not
in this mode, press the 4 Wheel Steer button, until the
4WS indicator, located to the right of the 4 Wheel Steer
button, lights up. If the 4WS indicator is flashing you
will have to center the steering wheel by turning it to the
left or right.
Slower Speed (below 40 m.p.h.)
At slower speeds the front and rear wheels will turn in
opposite directions. This helps the vehicle make tighter
turns, such as during parking, cornering and turning into
tight spaces.
Higher Speeds (40 m.p.h. and above)
At higher speeds the front and rear wheels will turn in
the same direction. This improves stability of the vehicle
during lane changes and sweeping turns.
4WS TOW: The 4WS TOW mode provides enhanced
stability allowing the trailer to follow the path of the tow
vehicle more closely, especially during lane changes.
In this mode the system operates much like the 4WS
mode, but is enhanced for trailer towing. It is
recommended for all types and weights of trailers.
To engage the 4WS TOW mode, press the 4 Wheel Steer
button until the 4WS and TOW indicators light up on
the instrument panel. If the TOW indicator is flashing
you will have to center the steering wheel by turning it
to the left or right. While in the 4WS TOW mode, it is
possible the steering wheel may be slightly off center.

Car Washes for QUADRASTEER
Equipped Vehicles
NOTICE:
Because your vehicle has a wider rear track some
car washes may be too narrow for your vehicle.
Conveyor systems on some automatic car washes
may damage your vehicle. Only use conveyor
system car washes with 13
-inch (33 cm) wide
conveyor rails and/or stationary washes with at
least 82 inches (208 cm) between the rails. Before
using the car wash check with the manager.
Horn
To sound the horn, press the center pad on the
steering wheel.

2-59
Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can raise it to the highest level
to give your legs more room when you exit and enter
your vehicle.
The tilt steering wheel lever
is located on the lower left
side of the column.
To tilt the wheel, hold the steering wheel and pull the
lever. Then move the steering wheel to a comfortable
position and release the lever to lock the wheel in place.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:

Turn and Lane Change Signals

Headlamp High/Low Beam Changer

Flash
-to-Pass Feature

Windshield Wipers

Windshield Washer

Cruise Control (If Equipped)
For information on the exterior lamps, see ªExterior
Lampsº earlier in this section.

2-63
Cruise Control (If Equipped)
With cruise control, you can
maintain a speed of about
25 mph (40 km/h) or more
without keeping your foot
on the accelerator.
This can really help on long trips. Cruise control does
not work at speeds below about 25 mph (40 km/h).
If you apply your brakes, or press the clutch pedal
(if equipped), the cruise control will disengage.CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.

2-67
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor located on
the top of the instrument panel in the defroster grille. Be
sure it is not covered, or the system will be on whenever
the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting longer
than the delay.To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
You may be able to turn off your automatic headlamp
system. See ªDaytime Running Lamps (DRL)º later in
this section for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need them.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your ignition
is in OFF, LOCK or ACCESSORY. To disable the
chime, turn the thumbwheel all the way down. In the
automatic mode, the headlamps turn off once the
ignition key is in OFF.

2-71
Cargo Lamp
The cargo lamp button is
located on the left side of
the instrument panel.
Press the button to turn the cargo lamp on. Press the
