Climate Controls
Climate Control System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system.
Operation
To change the current mode, select one of the following:
H(Vent):The air is directed though the instrument
panel outlets.
)(Bi-Level):The air is split between the instrument
panel outlets and the oor outlets. Cooler air is
directed to the upper outlets and warmer air to the oor
outlets.
6(Floor):Most of the air is directed through the oor
outlets with some air directed to the windshield and
side windows.
The left knob can also be used to select defog or
defrost mode. Information on defogging and defrosting
can be found later in this section.
9(Fan):Turn the center 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 turned on to run
the air conditioning compressor.
9(Off):To turn the fan off, turn the knob all the way
counterclockwise to the off position. Vehicles with Air Conditioning shown,
without Air Conditioning similar

Temperature Control:Turn the right knob clockwise
or counterclockwise to increase or decrease the
temperature inside the vehicle.
h(Recirculation):Press this button to prevent
outside air and odors from entering the vehicle or to help
heat or cool the air inside the vehicle more quickly.
An indicator light above the button will come on in this
mode. The air conditioning compressor also comes on.
This mode is not available for oor, defog and defrost
modes. When the recirculation button is pressed, the
recirculate indicator light will ash ve times and outside
air will be delivered. Operation in this mode during
periods of high humidity and cool outside temperatures
may result in increased window fogging. If window
fogging is experienced, select the defrost mode.
Outside Air:This mode allows outside air to circulate
through the vehicle. This mode is automatically
active if recirculate is not selected. There is no button
for outside air.
#(Air Conditioning):If your vehicle has air
conditioning, press this button to turn the air conditioning
system on or off. When this button is pressed, an
indicator light above the button comes on to show that
the 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 the vehicle to cool down. It also helps the
system to operate more efficiently.
For quick cool down on hot days:
1. Select the
Hmode.
2. Select the
hmode.
3. Select
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside of the vehicle to become
too dry. To prevent this from happening, after the air in
the vehicle has cooled, turn off the recirculation by
pressing the button again.
The air conditioning system removes moisture from the
air, so a small amount of water might drip underneath
the vehicle while idling or after turning off the engine.
This is normal.
The air conditioning compressor cannot be turned on
when the fan is off.

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(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 the windshield and side windows. When either
the defrost or defog mode is selected the system runs
the air conditioning compressor.
Turn the left knob to select the defog or defrost mode.
-(Defog):Use the defog mode to clear the windows
of fog or moisture and warm the passengers. Half of
the air is directed to the windshield and side window
outlets and the remaining to the oor outlets. To defog
the windows faster, turn the temperature control
knob clockwise to the warmest setting.
0(Defrost):Use the defrost mode to remove fog or
frost from the windshield more quickly. Most of the
air is directed to the windshield, with some air directed
to the side window outlets and the oor outlets.
To defrost the windows faster, turn the temperature
control knob clockwise to the warmest setting.
For best results, clear all snow and ice from the
windshield before defrosting.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger will only work when the
ignition is in ON/RUN.
<(Rear):Press the button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible. An indicator light above
the button comes on to show that the rear window
defogger is activated.
The rear window defogger turns off about 15 minutes
after the button is pressed. If turned on again, the
defogger only runs for about seven minutes before
turning off. If the vehicle is moving faster than 50 mph
(80 kph), the rear defogger will stay on. The defogger
can also be turned off by pressing the button again or by
turning off the engine.
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.

Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping equipment in good shape.
Keep the windshield washer uid reservoir lled.
Have good tires with proper tread depth. SeeTires
on page 5-49.
Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires inated to
recommended pressure?
Weather and Maps:Safe to travel? Have
up-to-date maps?

{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking the exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.Run the engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly.
This uses less fuel for the heat that you get and it keeps
the battery charged. You will need a well-charged
battery to restart the vehicle, and possibly for signaling
later on with the headlamps. Let the heater run for
a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.

If No Steam Is Coming From
Your Engine
An engine coolant temperature warning can indicate
a serious problem. SeeEngine Coolant Temperature
Warning Light on page 3-34.
If you get an engine coolant temperature warning,
but see or hear no steam, the problem may not be
too serious. Sometimes the engine can get a little
too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.If you get the engine coolant temperature warning with
no sign of steam, try this for a minute or so:
1. If you have an air conditioner and it is on, turn it off.
2. In heavy traffic, let the engine idle in NEUTRAL (N)
for automatic transmission or NEUTRAL for manual
transmission, while stopped. If it is safe to do so,
pull off the road, shift to PARK (P) or NEUTRAL (N)
and let the engine idle.
3. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning does not come back on, you can drive
normally.
If the warning continues and you have not stopped,
pull over, stop, and park your vehicle right away.
If there is still no sign of steam, you can idle the engine
for three minutes while you are parked. If you still
have the warning, turn off the engine and get everyone
out of the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.

(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 range and speed rating of
the tire. The load index represents the load carry
capacity a tire is certied to carry. The load
index can range from 1 to 279. The speed
rating is the maximum speed a tire is certied 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.
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.
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 pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat
from driving. SeeInflation - Tire Pressure on
page 5-56.
