Ashtrays and Cigarette Lighter
The ashtray is located at the lower part of the center
instrument panel. To remove the front ashtray for
cleaning, open the ashtray fully, press in the retaining
tab and pull the bin out.
Notice:If you put papers 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.
The cigarette lighter is located to the right of the front
ashtray. To use it, turn the ignition to ACC or ON, push
the cigarette lighter in all the way and let go. When it
is 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. 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.
Temperature Control:Turn the left knob clockwise or
counterclockwise to manually increase or decrease
the temperature inside your vehicle. Turn the knob to the
blue area for cool air and to the red area for warm air.
9(Fan):Turn the middle 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.Uplevel shown, Base similar
3-12

To change the current mode, select one of the following
from the right 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 rear outlets. Be sure to keep the area under the
front seats clear to allow the flow of air to the rear
compartment.
The right knob can also be used to select the defog and
defrost modes. Information on defogging and defrosting
can be found later in this section.
?(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.
If your vehicle has a recirculation button (uplevel model),
press the button to turn the recirculation mode on.
When the button is pressed, an indicator light in the
button will come on. Press the button again to return to
outside air mode.If your vehicle has an air intake lever (base model),
move the lever to choose the recirculation mode.
Using the recirculation mode for extended periods may
cause your windows to fog. If this happens, select the
defrost mode.
:(Outside Air):This mode brings outside air into
the vehicle.
If your vehicle has a recirculation button (uplevel model),
press the button until the recirculation mode is turned off.
Your vehicle will then return to outside air mode.
If your vehicle has an air intake lever (base model),
move the lever to choose the outside air mode.
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 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
compressor on and off. When the A/C button 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.
3-13

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. Select the recirculation mode.
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.
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.For best results, clear all snow and ice from the
windshield before defrosting.
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.
To help clear the side windows quickly, do the following:
1. Select the bi-level mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the temperature.
0(Defrost):This mode directs the air to the
windshield and the outboard outlets for the side
windows.
To help clear the windshield quickly, do the following:
1. Select the defrost mode.
2. Select the highest temperature.
3. Select the highest fan speed.
Do not drive the vehicle until all windows are clear.

Cooling System
When you decide it is safe to lift the hood, here is what
you will see:
A. Coolant Surge Tank with Pressure Cap
B. Electric Engine Cooling Fan{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.

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, 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 that hold the
tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies are
laid at alternate angles, less than 90 degrees to the
centerline of the tread.Cold Ination Pressure:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascal (kPa), before a tire has built up heat from
driving. SeeInflation - Tire Pressure on page 5-59.
Curb Weight:This means the weight of a motor vehicle
with standard and optional equipment including the
maximum capacity of fuel, oil and coolant, but without
passengers and cargo.
DOT Markings:A code molded into the sidewall of a
tire signifying that the tire is in compliance with the
U.S. Department of Transportation motor vehicle safety
standards. The DOT code includes the Tire Identification
Number (TIN), an alphanumeric designator which can
also identify the tire manufacturer, production plant,
brand and date of production.
