Certain power accessory plugs may not be
compatible to the accessory power outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer
for additional information on the accessory
power plugs.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should.
The repairs would not be covered by your
warranty. Do not use equipment exceeding
maximum amperage rating of 20 amperes.
Check with your dealer/retailer before adding
electrical equipment.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
Notice:Improper use of the power outlet
can cause damage not covered by your
warranty. Do not hang any type of accessory
or accessory bracket from the plug because
the power outlets are designed for accessory
power plugs only.Ashtray(s) and Cigarette Lighter
Your vehicle may have this feature. The front
ashtray can be placed in the instrument panel
extension at the center of the instrument panel.
Lift up on the ashtray door to open it.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
To use the cigarette lighter, push it in all the way
and let go. When it’s ready, it will pop back
out by itself.
Notice:Holding a cigarette lighter in while
it is heating does not let the lighter back away
from the heating element when it is hot.
Damage from overheating can occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in while
it is heating.

Climate Controls
Climate Control System
With this system you can control the heating,
cooling and ventilation for your vehicle.
Turn the right knob clockwise or counterclockwise
to direct the airflow inside of your vehicle.
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 floor outlets. Some
air may be directed toward the windshield.
6(Floor):This mode directs most of the air to
the floor outlets with some air directed to the
outboard outlets (for the side windows) and some
air directed to the windshield.
The right knob can also be used to select the
defrost and defog modes. Information on defogging
and defrosting can be found later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the
fan speed.
Temperature Control:Turn the center knob
clockwise or counterclockwise to increase
or decrease the temperature inside your vehicle.
160

If your vehicle has air conditioning, your heating/air
conditioning controls will look like this:
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
A/C (Air Conditioning):This setting will begin to
cool and dehumidify the air inside of your vehicle.
MAX A/C (Maximum Air Conditioning):Turn the
right knob to MAX A/C for maximum cooling.
This setting cools the air the fastest, by
recirculating the inside air.
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 is
used properly. There are two modes to clear fog or
frost from your windshield and side windows.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. For best results, clear all snow and
ice from the windshield before defrosting.
Turn the knob on the right of the climate control
panel to select the defog or defrost mode.
-(Defog):With this setting, the outside air
comes out of both the floor and defroster outlets.
Adjust the temperature knob for warmer or
cooler air. The air conditioning compressor may
operate in this setting to dehumidify the air.
1(Defrost):This setting operates the defroster.
Most of the air comes out near the windshield,
with some going to the floor outlets and front side
windows. The air conditioning compressor may
operate in this setting to dehumidify the air.
The defog setting is useful for cold weather with a
large number of passengers or very humid
conditions to help keep the windshield clear. Use
defrost to remove fog or ice from the windshield
quickly in extremely cold conditions. The
temperature knob should be in the red area and
the fan control toward high. Do not drive the
vehicle until all the windows are clear.
161

Rear Heating System
Your vehicle may have a rear heating system that
allows you to adjust the amount of air flowing
into the rear of the vehicle, from the front-seating
area. This feature works with the main
climate-control system in your vehicle.
REAR HEAT:The thumbwheel for this system is
located to the left of the audio system.
9(Fan):Turn the thumbwheel up or down to
increase or decrease the amount of heated air sent
to the rear-seating area.
HI:Turn the thumbwheel to this position to supply
the most amount of heat to the rear-seating area.
LO:Turn the thumbwheel to this position to supply
the least amount of heat to the rear-seating area.
OFF:Turn the thumbwheel to this position to turn
the rear heating system off.
163

Rear Air Conditioning and
Heating System
Your vehicle may have a rear heating and
air-conditioning system. This system regulates the
temperature, the fan speed and the air delivery for
the rear-seat passengers only. It also works with
the main climate-control system in your vehicle.
Use this control panel when you would like to
maintain a separate temperature setting. Adjust the
direction of the airflow or adjust the fan speed
for the rear seat passenger(s).If your vehicle has a 135 inch (343 cm) wheelbase,
a rear control panel for this system is located in
the second row behind the driver in the rear
of your vehicle. A rear seat passenger can use
this control panel to personally adjust the
temperature, the direction of the airflow and the
fan speed for the rear seating area.
The fan knob located on the front climate control
panel must be turned to REAR CNTL to allow a rear
seat passenger to use the control panel in the rear
seating area. Performing this action disables the
front control panel. To return control to this panel,
move the fan knob out of REAR CNTL.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area
your engine is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under
normal operating conditions, you should pull off the
road, stop your vehicle, and turn off the engine
as soon as possible.
SeeEngine Overheating on page 315.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition, and
emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The Check Engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.

Driving with a Trailer
{CAUTION:
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 not see or smell CO. It
can cause unconsciousness or death. See
Engine Exhaust on page 132. 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.
CAUTION: (Continued)
CAUTION: (Continued)
Do not use the climate control
setting for maximum air because it
only recirculates the air inside your
vehicle. See Climate Control System
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 all trailer hitch parts 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.
282

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring and a heavy-duty turn signal
flasher (included in the optional trailering package).
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 gearbefore
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 and/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, seeEngine Overheating
on page 315.
