154 Climate Controls
A:Turn clockwise or
counterclockwise to increase or
decrease the fan speed. Turning the
fan control to 0 turns the fan off. The
fan must be turned on to run the air
conditioning compressor.
Air Delivery Mode Control : Turn
clockwise or counterclockwise to
change the current airflow mode.
Select from the following air delivery
modes:
Y: Air is directed to the instrument
panel outlets.
\: Air is divided between the
instrument panel and floor outlets.
[: Air is directed to the floor
outlets, with some air directed to the
rear outlets.
W: This mode clears the windows
of fog or moisture. Air is directed to
the floor, windshield, and side
window outlets.
1: This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield and side window outlets. Do not drive the vehicle until all
windows are clear.
In defrost or defog mode, excessive
air conditioning use can cause the
windows to fog. If this happens,
change the air delivery mode to
Y
and reduce the fan speed.
#:
If equipped with air
conditioning, follow these steps to
use the system. Turn
Ato the
desired speed. The air conditioning
does not operate when the fan
control knob is in the off position.
Press
#to turn the air conditioning
on and off. When
#is pressed, an
indicator light comes on to show
that the air conditioning is on.
For quick cool down on hot days:
1. Open the windows to let hot air escape.
2. Press
M.
3. Press
#.
4. Select the coolest temperature.
5. Select the highest
Aspeed. Using these settings together for
long periods of time may cause the
air inside the vehicle to become too
dry. To prevent this from happening,
after the air in the vehicle has
cooled, turn the recirculation
mode off.
M:
This mode recirculates and
helps to quickly cool the air inside
the vehicle. It can be used to reduce
the entry of outside air and odors.
Press
Mto turn the recirculation
mode on. An indicator light comes
on to show that the recirculation is
on. Press
Magain to return to
outside air mode.
Using the recirculation mode for
extended periods may cause the
windows to fog. If this happens,
select the defrost mode.
Max

conditioning is selected and the
temperature is set to the coolest
setting while the outside air
temperature is warm. When Max
#
is activated, the air inside the
vehicle is automatically recirculated,

Maintenance
Air Intake
Clear away any ice, snow, or leaves
from the air intake at the base of the
windshield that can block the flow of
air into the vehicle.
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
SeeMaintenance Schedule 0278.
To find out what type of filter to use,
see Maintenance Replacement
Parts 0288.1. Open the glove box completely
and disconnect the damper on
the outboard side.
2. Push in both sides of the glove box and pull to remove.3. Install the new air filter.
4. Reinstall the air filter cover andglove box in reverse order.
See your dealer if additional
assistance is needed.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.

Climate Controls 157
It should only be replaced by a new
evaporator to ensure proper and
safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.
The air conditioning system requires
periodic maintenance. See
Maintenance Schedule0278.

Vehicle Care 217
Caution
Do not run the engine if there is a
leak in the engine cooling system.
This can cause a loss of all
coolant and can damage the
system and vehicle. Have any
leaks fixed right away.
If Steam Is Coming from the
Engine Compartment
{Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
. Stops after high-speed driving.
. Idles for long periods in traffic.
If the overheat warning is displayed
with no sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the
highest fan speed. Open the
windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or
N (Neutral) and let the
engine idle.
If the overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally
and have the cooling system
checked for proper fill and function.
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down.
Washer Fluid
What to Use
When the vehicle needs windshield
washer fluid, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall
below freezing, use a fluid that has
sufficient protection against
freezing.

(4) 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.
(5) Rim Diameter
:Diameter of
the wheel in inches.
(6) Service Description
:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying 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
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch). Accessory Weight
:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, 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 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.
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 Tire Pressure
:The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. See Tire Pressure
0 240.
Curb Weight
: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
(DOT) Motor Vehicle Safety

includes the Tire Identification
Number (TIN), an alphanumeric
designator which can also
identify the tire manufacturer,
production plant, brand, and
date of production.
