Fan Control
9(Fan):Turn the center knob
toward 4 to turn the system on or
increase fan speed.
If the airflow seems low when the
fan is at the highest setting, the
passenger compartment air filter
may need to be replaced. For
more information, see Passenger
Compartment Air Filter on page 7-4
and Scheduled Maintenance on
page 10-3.
Temperature Control
Turn the right knob clockwise or
counterclockwise to increase or
decrease the temperature inside the
vehicle. Air Delivery Mode Control
Turn the left knob to select from the
following modes:
H(Vent):
Air is directed to the
upper instrument panel outlets.
)(Bi-Level): Air is directed to the
upper instrument panel outlets
and the floor outlets.
6(Floor): Air is directed to the
floor and side window outlets.
-(Defog): Air is directed between
the windshield, side windows,
instrument panel outlets and the floor
outlets. Use the defog mode to clear the
inside of the windshield of fog
or moisture and to warm the
passengers. The air conditioning
compressor runs automatically in this
setting without pressing A/C, unless
the outside temperature is at or
below 32°F (0°C).
1(Defrost):
Air is directed to the
windshield, instrument panel
outlets and the side windows.
Use the defrost mode to remove
fog or frost from the outside of the
windshield more quickly. The air
conditioning compressor runs
automatically in this setting without
pressing A/C, unless the outside
temperature is at or below
32°F (0°C).
Do not drive the vehicle until all the
windows are clear.

Air Conditioning
For vehicles with this feature, there
will be the following controls:
A/C (Air Conditioning):Press to
turn the air conditioning system
on or off. An indicator light shows
that it is on.
MAX A/C (Maximum Air
Conditioning): Press the A/C and
recirculation buttons at the same
time to select MAX A/C.
On hot days, open the windows to let
hot inside air escape; then close
them. The vehicle will cool quicker
and the A/C system operates more
efficiently.
Because the A/C system removes
moisture from the air, it is normal
for a small amount of water to
drip under the vehicle while idling
or just after turning the engine off.
Recirculation
?(Recirculation): Press to turn
the recirculation mode on or off.
An indicator light shows that it is on.
This mode recirculates the air inside
the vehicle and helps to heat or cool
the air more quickly. It can be used to
prevent outside air and odors from
entering the vehicle.
Press the button again to turn the
recirculation mode off and the
outside air mode on. Recirculation is
automatically turned off when the
climate control system mode knob
is turned to defog, defrost, or is
positioned between modes.
Rear Window Defogger
The rear window defogger uses a
warming grid to clear fog from the
rear window. It will only work when
the ignition is in the ON/RUN
position.
=(Rear Defogger): Press to turn
the rear window defogger on or off.
An indicator light shows that it is on.
The rear window defogger stays on
for 15 minutes. Clear any snow from
the rear window.
Notice: Do not use a razor
blade or sharp object to clear the
inside rear window. Do not adhere
anything to the defogger grid lines
in the rear glass. These actions
may damage the rear defogger.
Repairs would not be covered by
your warranty.

Tire Designations
Tire Size
The following illustration
shows an example of a typical
passenger vehicle 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 60, as shown in
item C of the illustration, it would
mean that the tire’s sidewall is
60 percent 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
index and speed rating of the tire.
The load index 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.
Tire Terminology and
De nitions
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.
