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 will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may 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.
159

)(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.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.
160

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.
Turn the center knob clockwise or
counterclockwise to change the direction of the
airflow in the rear seating area.

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 309.
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.
278

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, see
Engine Overheating on page 309.
