Climate Controls
Climate Control System
With this system you can control the heating,
cooling and ventilation for your vehicle.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan
speed. In any setting other than off, the fan
will run continuously with the ignition on. The fan
must be on in order for the air conditioning
compressor to run.To change the current mode, select one of the
following from the middle knob:
E(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, and then
directs the remaining air to the floor outlets.
5(Floor):This mode directs most of the air to
the floor outlets. Some of the air will also be
directed to the windshield, instrument panel side
outlets, and the rear outlets. Be sure to keep
the area under the front seats clear to allow the
flow of air to the rear compartment.
The middle knob can also be used to select the
defog and defrost modes. Information on defogging
and defrosting can be found later in this section.
Temperature Control:Turn the right knob
clockwise or counterclockwise to manually
increase or decrease the temperature inside your
vehicle. Turn the knob to the blue area to get
cool air and to the red area to get warm air.

A/C (Air Conditioning):If your vehicle has air
conditioning, follow these steps to use the system.
Start the engine and set the fan control knob to
the desired fan speed. The air conditioning
compressor does not operate when the fan control
knob is in the OFF position. Press the A/C
button to turn the air conditioning system on and
off. When A/C is pressed, an indicator light in
the button will come on to let you know that air
conditioning is activated.
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.
For quick cool down on hot days, do the
following:
1. Select the vent mode.
2. Select the highest fan speed.
3. Press the A/C button.
4. Press the recirculation button.
5. Select the coolest temperature.Using these settings together for long periods of
time may cause the air inside of your vehicle
to become too dry. To prevent this from
happening, after the air in your vehicle has cooled,
turn the recirculation mode off.
The air conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.
?(Recirculation):This mode keeps outside air
from coming into the vehicle. It can be used to
prevent outside air and odors from entering your
vehicle or to help heat or cool the air inside
your vehicle more quickly.
Press this button to turn the recirculation mode on.
When the button is pressed, an indicator light in
the button will come on. Press this button again to
return to outside air mode.
Using the recirculation mode for extended periods
may cause your windows to fog. If this happens,
select the defrost mode.
156

Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity or moisture condensing on the cool
window glass. This can be minimized if the climate
control system is used properly. There are
two modes to clear fog or frost from your
windshield. 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.
Select one of these available modes from the
right knob.
É(Defog):This mode directs most of the air to
the windshield and the floor outlets. A small
amount of air is also directed to the outboard
outlets for the side windows and to the instrument
panel side outlets.When you select this mode, the system runs the
air-conditioning compressor. To defog the windows
faster, turn the temperature control knob
clockwise to the warmest setting.
0(Defrost):This mode directs most of the air to
the windshield and the outboard outlets for the
side windows. A small amount of air is also
directed to the instrument panel side outlets.
When you select this mode, the system runs the
air-conditioning compressor. To defrost the
windows faster, turn the temperature control knob
clockwise to the warmest setting.
Do not drive the vehicle until all windows are clear.

{CAUTION:
An electric engine cooling fan under the
hood can start up even when the engine
is not running and can injure you. Keep
hands, clothing, and tools away from any
underhood electric fan.
If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
Make sure that the air conditioning is turned off.
The coolant level should be between the Minimum
and Maximum marks on the coolant surge tank
when the engine is cool. If it is not, you may have
a leak at the pressure cap or in the radiator
hoses, heater hoses, radiator, water pump, or
somewhere else in the cooling system.
{CAUTION:
Heater and radiator hoses, and other
engine parts, can be very hot. Do not
touch them. If you do, you can be burned.
Do not run the engine if there is a leak.
If you run the engine, it could lose all
coolant. That could cause an engine re,
and you could be burned. Get any leak
xed before you drive the vehicle.
If there seems to be no leak, with the engine on,
check to see if the electric engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, your vehicle
needs service.
Notice:Engine damage from running your
engine without coolant is not covered by your
warranty.

(C) Aspect Ratio:A two-digit number that
indicates the tire height-to-width measurements.
For example, if the tire size aspect ratio is 70,
as shown in item C of the illustration, it would
mean that the tire’s sidewall is 70% as high as it
is wide.
(D) Construction Code:A letter code is used
to indicate the type of ply construction in the tire.
The letter R means radial ply construction; the
letter D means diagonal or bias ply construction;
and the letter B means belted-bias ply
construction.
(E) Rim Diameter:Diameter of the wheel in
inches.
(F) Service Description:These characters
represent the load range and the speed rating
of a tire. The load range represents the load carry
capacity a tire is certified to carry. The speed
rating is the maximum speed a tire is certified to
carry a load. Speed ratings range from A to Z.Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the
tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples
of optional accessories are, automatic
transmission/transaxle, power steering, power
brakes, power windows, power seats, and
air conditioning.
Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is located
between the plies and the tread. Cords may be
made from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.

Engine Cooling System Inspection
Inspect the hoses and have them replaced if
they are cracked, swollen or deteriorated. Inspect
all pipes, fittings and clamps; replace as needed.
Clean the outside of the radiator and air
conditioning condenser. To help ensure proper
operation, a pressure test of the cooling system
and pressure cap is recommended at least once
a year.
Throttle System Inspection
Inspect the throttle system for interference or
binding, and for damaged or missing parts.
Replace parts as needed. Replace any
components that have high effort or excessive
wear. Do not lubricate accelerator and cruise
control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines
and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for
wear and rotors for surface condition. Inspect other
brake parts, including calipers, parking brake,
etc. You may need to have your brakes inspected
more often if your driving habits or conditions
result in frequent braking.
