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 airow inside of your vehicle.To change the current mode, select one of the following:
)(Bi-Level):This mode directs approximately half
of the air to the instrument panel outlets and directs
most of the remaining air to the oor outlets. Some air
may be directed toward the windshield.
H(Vent):This mode directs air to the instrument
panel outlets.
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.
A/C (Air Conditioning):This setting brings in outside
air, cools and dehumidies it.
MAX A/C (Maximum Air Conditioning):This setting
cools the air the fastest, by recirculating the inside air.
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.
3-21

Defogging and Defrosting
Turn the right knob to select the defog or defrost mode.
-(Floor/Defog):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 dehumidfy 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. The air
conditioning compressor may operate in this setting to
dehumidify the air.
The bi-level 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.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in RUN.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 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:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.

Rear Air Conditioning System
Your vehicle may have a rear air conditioning system
that allows you to adjust the fan speed in the rear
seating area, from the front seating area. This feature
works with the main climate control system in your
vehicle.
The thumbwheel for this system is located to the right of
the controls for the climate control system.
Turn the thumbwheel up or down to increase or
decrease the amount of cooled air sent to the rear
seating area.To direct the airow to the rear seating area, use the
right knob located on the main climate control panel.
Generally the upper outlets are used for air conditioning
and the oor outlets are used for heating.
9(Fan):Move the thumbwheel up or down to HIGH,
MED (Medium) or LOW to increase or decrease the
fan speed in the rear seating area. Move the
thumbwheel to OFF to turn off the fan.
To increase or decrease the temperature for the entire
vehicle, use the center knob located on the main
climate control panel.
3-24

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, seeClimate Control System on page 3-21.
For information on ventilation, seeOutlet Adjustment on
page 3-23.
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 briey 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.
3-25

Charging System Light
This light should come on
briey when you turn on
the ignition, before starting
the engine, as a check
to show you it is working.
After the engine starts, the light should go out. If it stays
on or comes on while you are driving, you may have
a problem with your charging system. It could indicate a
problem with the generator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light
on, it helps to turn off all your accessories, such as the
radio and air conditioner.
Voltmeter Gage
When your engine is not
running, but the ignition is
on (in the RUN position),
the gage shows your
battery’s state of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
