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 air¯ow 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 ¯oor outlets. Some air may be
directed toward the windshield.
6(Floor):This mode directs most of the air to the
¯oor 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
mode. 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.
3-19

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.
Rear Heating System
Your vehicle may have an optional rear heating system
that allows you to adjust the amount of air ¯owing
into the rear of the vehicle, from the front-seating area.
This feature works with the main climate-control
system in your vehicle.AUX (Auxiliary Heating System):The thumbwheel for
this system is located to the right 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.
9(Off):Turn the thumbwheel to this position to turn
off the rear heating system.

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 air¯ow or adjust the fan speed for the rear-seat
passenger(s).The 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
air¯ow 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. Front Climate-Control Panel
Rear Climate-Control Panel

Turn the center knob clockwise or counterclockwise
to change the direction of the air¯ow in the
rear-seating area.
To change the current mode, select one of the following:
D(Vent):Use this mode to direct air to the upper
outlets, with a little air directed to the ¯oor outlets.
2(Floor):Use this mode to direct most of the air to
the ¯oor outlets.
9(Fan):Turn the left knob clockwise or
counterclockwise to HIGH, MED (Medium) or LOW to
increase or decrease the fan speed in the rear-seating
area. Turn the knob to OFF to turn off the fan.
(Temperature Control):To increase or decrease the
temperature for the rear of the vehicle, turn the right
knob located on the climate-control panel.
The air-conditioning system on the main climate-control
panel must be turned on to direct cooled air to the
rear of the vehicle. If it is not on, then the temperature
in the rear of the vehicle will remain at cabin
temperature.
Be sure to keep the area under the front seats clear of
any objects so that the air inside of your vehicle can
circulate effectively.For information on how to use the main climate-control
system, see
Climate Control System on page 3-19listed previously in this section. For information
on ventilation, see ªOutlet Adjustmentº earlier in this
section.
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.
-(Blend):With this setting, the outside air comes out
of both the ¯oor 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 ¯oor outlets and front side windows.
3-22

The air conditioning compressor may operate in this
setting to dehumidify the air.
The blend 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.
Rear Window Defogger
Press this button to turn the rear window defogger on or
off. Be sure to clear as much snow from the window
as possible.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window and will only
work when the ignition is RUN.
The rear window defogger will turn off several minutes
after the button is pressed. If turned on again, the
defogger will run for several more minutes before turning
off. The defogger can also be turned off by pressing
the button again or by turning off the engine.
Notice:Don't use a razor blade or something else
sharp on the inside of the rear window. If you
do, you could cut or damage the defogger 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.
Warning Lights, Gages and
Indicators
This part describes the warning lights and gages
that may be on your vehicle. The pictures will help
you locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you will
see in the details on the next few pages, some
warning lights come on brie¯y when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages
and warning lights work together to let you know when
there's a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section
that tells you what to do about it. Please follow this
manual's advice. Waiting to do repairs can be
costly ± and even dangerous. So please get to know
your warning lights and gages. They're a big help.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You'll know how
fast you're going, how much fuel you're using, and many other things you'll need to know to drive safely, and
economically.United States version shown, Canada similar
3-24

Speedometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles (used in the United States)
or kilometers (used in Canada).
You may wonder what happens if your vehicle needs a
new odometer installed. Laws vary as to the procedure
that must be followed, so check with your state or
provincial vehicle registration office. But generally, if the
new odometer can be set to the mileage total of the
old odometer, then it must be. But if it can't, then it's set
at zero, and a label must be put on the driver's door
to show the old mileage reading when the new odometer
was installed.
Trip Odometer
The trip odometer can tell
you how far your vehicle
has been driven since
you last set the trip
odometer to zero.
To reset the trip odometer, fully press the reset button
located near the trip odometer readout.
The trip odometer can show either total miles or trip
miles using this button located on the instrument cluster.
3-25

Electronic Road-Speed Governor
Your vehicle may have this feature. This system
automatically controls top vehicle speed. The system
controller receives a signal from the vehicle speed
sensor and reduces power when the vehicle speed
reaches the maximum 65 mph (105 km/h) governed
speed.
Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come on for several seconds to remind people to fasten
their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay
on for several seconds,
then it will ¯ash for
several more.
If the driver's belt is already buckled, neither the tone
nor the light will come on.
