Ashtrays and Cigarette Lighter
The front ashtray and cigarette lighter are located at
the lower part of the center instrument panel, behind a
cover. Press in the cover and it will automatically open.
To remove the front ashtray for cleaning, pull the bin
out. To replace, press the bin back into place.
The rear ashtray is located at the rear of the center
console. To remove the rear ashtray, press in the
retaining spring and pull the bin out. To replace the rear
ashtray, insert the bottom tabs first and then press in
the retaining spring and push the ashtray closed.
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
Your vehicle may have a manual 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.
0 (Off):To turn the fan off, turn the knob all the way
counterclockwise to the off position.
3-18

TEMP (Temperature):Turn the middle 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.
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. If your vehicle has rear outlets, some of the
air will also be directed to them. 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 in 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 or off.
When the button is pressed, an indicator light in the
button will come on. Using the recirculation mode for
extended periods may cause your windows to fog.
If this happens, select the defrost mode.
A/C (Air Conditioning):Press this button to turn the
air conditioning compressor 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. Select the recirculation mode.
5. Select the coolest temperature.
3-19

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.
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.

?(Recirculation):Press this button to keep
outside air from coming in 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 or off.
Using the recirculation mode for extended periods may
cause your windows to fog. If this happens, select
the defrost mode.
A/C (Air Conditioning):Press this button to override
the automatic system and turn the air conditioning
system on or off. When A/C is pressed, the indicator
light on the display panel will come on to let you know
that it is activated.

system off, or press the OFF button to turn the entire
system off.
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, press the AUTO button
and the system will automatically enter recirculation
mode and the temperature will be at the full cold position
for maximum cooling.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.
Outside Temperature:To display the outside
temperature, press the temperature control knob.
Pressing this knob again will cancel the outside
temperature display, otherwise the display will return
to the temperature inside of the vehicle after about
five seconds.
The outside temperature sensor is located near the
front bumper, so the displayed temperature may
be affected by road or engine heat while the vehicle
is idling or traveling at slow speeds. For this reason,
the displayed temperature will be most accurate
at speeds over 25 mph (40 km/h).

Cooling System
When you decide it is safe to lift the hood, here is what
you will see:
A. Coolant Surge Tank
with Pressure CapB. 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 Size
The following illustration shows an example of a typical
passenger car tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter “P” as
the first character in the tire size means a passenger
vehicle tire engineered to standards set by the U. S. Tire
and Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(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, power steering,
power brakes, power windows, power seats, and air
conditioning.
Aspect Ratio:The relationship of a tire’s height to
its width.
