Liftgate/Liftglass
It can be dangerous to drive with the liftgate or
liftglass open because carbon monoxide (CO)
gas can come into your vehicle. You can’t see
or smell CO.
It can cause unconsciousness
and even death. If you must drive with the
liftgate open or if electrical wiring or other
cable connections must pass through the seal between the body and the liftgate or liftglass:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air into your vehicle. See “Climate Controls”
in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
See “Engine Exhaust” in the Index.

Ashtrays and Cigarette Lighter
Your vehicle may have this feature. The front ashtray is
removable and fits into the front cupholder.
Notice: Don’t put papers or other flammable items
into your ashtrays. Hot cigarettes or other smoking
materials could ignite them, causing a damaging fire.
To remove the front ashtray, pull the covered bin
out of
the cupholder. To use the lighter, press
it in all the way, and let go.
When it’s ready, it will
pop back out by itself.
Notice: Don’t hold a cigarette lighter in with your
hand while
it is heating. If you do, it won’t be able to
back away from
the heating element when it’s
ready. That can make
it overheat, damaging the
lighter and the heating element.

Climate Controls
Dual Automatic Climate Control
System
Your vehicle may have the optional dual automatic
climate control system. With this system you can control
the heating, cooling and ventilation for your vehicle.
When your vehicle is first started, the display will show
the driver’s temperature setting and air delivery mode for
five seconds. Then it will show the outside temperature.
0 (Off): Press this button to turn off the entire climate
control system. Outside air will still enter the vehicle,
and will be directed to the floor. Press the AUTO button,
the mode button, the fan arrows, or either temperature
knob to turn the system on.
Q., *d (Mode): Press this button to manually select the air
delivery mode to the floor, instrument panel, or
windshield outlets. The system will stay in the selected
mode until the mode button is pressed again or the
AUTO button is pressed.

clockwise or counterclockwise to manually raise or lower
the temperature on the driver’s side of the vehicle. The
display will show the temperature setting decreasing or
increasing and the word “DRIVER” will light up. This knob
can also adjust the passenger’s side temperature setting
simultaneously
if the two zones are linked. The words
“DRIVER and PASS” will then light up.
Passenger’s Side Temperature Knob: Turn this knob
clockwise or counterclockwise to manually raise or lower
the temperature on the passenger’s side of the vehicle.
The display will show the temperature setting decreasing
or increasing and the word “PASS” will light up. The
passenger’s temperature setting can be set to match and
link to the driver’s temperature setting by pressing and
holding the AUTO button for three seconds. By adjusting
the driver’s side temperature setting, the passenger’s
side temperature setting will follow and both “DRIVER
and PASS” will be displayed. 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 two hours.

decal or anything similar to the defogger grid.
Do not attach a temporary vehicle license, tape, a decal
or anything similar
to the defogger grid.
Outlet Adjustment
Use the air outlets located in the center and on the side
of your instrument panel
to direct the airflow.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the vent setting
to direct outside
air through your vehicle.
Your vehicle’s ventilation system supplies outside air
to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air inlet
grilles, through the vehicle and out the air exhaust
valves.
Outside air will also enter the vehicle when the heater
or the air conditioning compressor is running, unless you
have the recirculation button pushed in.

Operation Tips
e
e
e
Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such
as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the
fan knob all the way
to the right for a few moments
before driving. This helps clear the intake ducts
of snow and moisture, and reduces the chance of
fogging the inside of your window.
Keep the air path under the front seats clear of
objects. This helps air
to circulate throughout
your vehicle.
Adding outside equipment
to the front of your
vehicle, such as hood-air deflectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment
to the outside of your vehicle.
Rear Climate Control System
The lower buttons on the rear seat audio are used to
adjust the rear seat comfort controls. The temperature of
the air coming through the rear outlets is determined
by the front passenger’s temperature setting. The button
with the up and down arrows on
it regulates the fan
speed. The mode button is used
to change the direction
of airflow (upper, bi-level or floor) to the rear seat
area. To turn the rear comfort controls off, press the
lower
PWR button.

Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the panel outlet setting to direct
outside air through your vehicle. Air will flow through
the instrument panel outlets.
Your vehicle’s flow-through ventilation system supplies outside air into the vehicle when it’s moving. When the
vehicle is not moving, you can get outside air to flow
through by selecting any air delivery mode and any fan
speed. Move the control
in the center of each outlet side-to-side
to direct the air from the outlet. Use the thumbwheel
under the outlet to close the louvers. For the most
efficient airflow and temperature control, keep the
louvers in the fully opened position.
The rear seat outlets can be used to adjust the airflow
toward either seating area, the floor or upward. Move the
control in the center of each outlet side-to-side to
direct airflow.
Your vehicle has air outlets that allow you to adjust the
direction and amount
of airflow inside the vehicle.

Don’t leave an unsecured child resL,int in
your vehicle.
When you carry something inside the
vehicle, secure it whenever you
can.
Don’t leave a seat folded down unless you
need to.
There’s also important loading information for off-road
driving in this manual.
Electronically Controlled Air
Suspension System
Your vehicle may be equipped with an electronically
controlled air suspension system that automatically
keeps your vehicle level as you load and unload. The
system includes a compressor, two height sensors
and two air springs supporting the rear axle. The system also has an internal clock to prevent
overheating.
If the system overheats, all leveling function
stops until the system cools down. During this time, the
indicator light on the air inflator system will be flashing.
The ignition has
to be on for the system to inflate, in
order
to raise the vehicle to the standard ride height after
loading. The system can lower the vehicle
to the
standard ride height after unloading with the ignition on
and also for up
to 30 minutes after the ignition has
been turned
off.
You may hear the compressor operating when you load
your vehicle, and periodically as the system adjusts
the vehicle
to the standard ride height.
Load leveling will not function normally with the inflator
hose attached
to the inflator outlet. Remove the
inflator hose from the outlet during loading and
unloading.
If the vehicle is parked for an extended period of time,
some bleed down of the suspension is normal. Upon
starting the vehicle, proper height will be achieved.

Driving with a ‘railer
I..
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon
monoxide
(CO) could come into your vehicle.
You can’t see or smell CO.
It can cause
unconsciousness
or death. See “Engine
Exhaust” in the Index.
To maximize your safety
when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
If exhaust does come into your vehicle
through a window
in the rear or another
opening, drive with your front, main heating
or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle.
Do not use
the climate control setting for maximum air because
it only recirculates the air inside
your vehicle. See “Climate Controls”
in the
Index. Towing a trailer requires a certain
amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you
start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment.
If the trailer has
electric brakes,
start your vehicle and trailer moving and
then apply the trailer brake controller by hand
to be
sure the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally
to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need
to go much farther beyond the
passed vehicle before you can return
to your lane.
4-50

Backing Up
Hold the bottom of the steering wheel with one hand.
Then,
to move the trailer to the left, just move that hand
to the left.
To move the trailer to the right, move your
hand to the right. Always back up slowly and,
if possible,
have someone guide you.
Making Turns
Notice: Making very sharp turns while trailering
could cause the trailer to
come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns
than normal. Do this
so your trailer won’t strike
soft shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
The arrows on your instrument panel will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also flash, telling other drivers
you’re about to turn, change lanes or stop. When towing a trailer,
the arrows on your instrument
panel will flash for turns even
if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
You can tow in DRIVE
(D). You may want to shift the
transmission to THIRD
(3) or a lower gear, under heavy
loads or hilly conditions.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If you turn your
engine
off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating, To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in PARK (P) for a
few minutes before turning the engine
off. If you do get
the overheat warning, see
Engine Overheating on
page 5-24.
