With this system, you can control the heating, cooling
and ventilation in your vehicle.
Standard Climate Control System
I' II
Fan Control
The knob on the left side of the heating system control
panel controls the fan speed.
To increase airflow, move
the
knob to the right. To decrease airflow, move it to
the left.
The middle knob on the control panel lets you select the
relative temperature
of the air flowing into the passenger
area
of your vehicle. Move the knob to the right toward
the red area for warmer air. Move the
knob to the left
toward the blue area for cooler air.
Mode Knob
The right knob on the control panel allows you to
choose the direction of air delivery.
OFF: This setting turns the system off. Some outside air
will still enter the vehicle whenever the vehicle is
moving forward.
MAX A/C: This setting provides maximum cooling
with the least amount of work. MAX A/C recirculates
much
of the air inside your vehicle so it cools quickly.
This setting directs most of the air through the
instrument panel vents and
a small amount through the
floor vents.
A/C: This setting cools the air entering your vehicle and
directs most of the air through the instrument panel
vents and
a small amount through the floor vents.

fl VENT This setting directs most of the air through
the instrument panel outlets and a small amount through
the floor outlets. The air conditioning compressor is not
working when VENT
is selected.

Fan Control
The knob on the left side of the electronic climate control
panel controls the fan speed. To manually increase airflow, move the knob to the right.
To manually decrease aifflow,
move it
to the left.
OFF: If the knob is in OFF, outside air will still enter
the vehicle, and will be directed based
on the position of
the mode knob.
AUTO: If the knob is in AUTO, the fan speed will vary
as the system maintains the selected temperature.

Downloaded from www.Manualslib.com manuals search engine With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor
outlets.
As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow will adjust between the
instrument panel air outlets and floor outlets. On bright
sunny days in cool weather, the airflow may come out of
the air conditioning and floor outlets (bi-level mode) to
maintain comfort and prevent stuffiness.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the coolant warms
up, the blower fan speed will gradually increase and air
will flow from the heater outlets, with some airflow to
the windshield to prevent fogging under most
normal conditions.
If your vehicle
is sitting out on a warm day and you
have the fan set
on AUTO, the air will first flow out of
the floor air outlets for a few seconds. That is normal.
This
is to expel hot air from the air outlets. As the air is
cooled, the airflow will move through the air
conditioning outlets. Be careful
not to put anything over the solar sensor
located around the center of the instrument panel.
This sensor is used by the automatic system to
regulate temperature.
Mode Knob - Manual Operation
The right knob on the control panel allows you to
choose the direction of air delivery.
You can choose to set the climate control system
operations yourself, or let the system work for
you
by placing the system in AUTO mode. See “Mode
Knob
- Automatic Operation” earlier in this section.

On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle
to cool down. Then keep your windows closed
for the air conditioner to work its best.
For quick cool-down on very hot days, use MAX A/C
with the temperature knob turned to the left. This setting
should be used to keep odors and/or dust from entering
the vehicle. For normal cooling
on hot days, use A/C
with the temperature knob turned to the left.
On vehicles equipped with the Electronic Climate
Control system, this same performance can be achieved
as long as the A/C is enabled and the outside air button
is not active.
Heating
On cool but sunny days, use BI-LEVEL A/C to deliver
warm air to the
floor and cooler air to the instrument
panel outlets.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle’s engine speed and
power. This is normal because the system is designed
to cycle the compressor on and off to keep the
desired temperature.
The heater works best if you keep your windows closed
while using it. On cold days,
use HEATER with the
temperature knob turned
to the right. BLEND is useful
in cool weather when
you have fog or ice on the
windshield or side windows.
If you use the optional engine coolant heater before starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use
VENT to direct outside air
through your vehicle. Airflow is through the instrument
panel outlets.
Your vehicle’s ventilation system supplies outside air to
the inside
of your vehicle when it is moving. When the
vehicle is
not moving, you can get outside air to flow
through by selecting any mode and any fan speed.

- If your vehicle has this
option, the rear window
will have lines that warm
the glass.
For
I - - t results, clear the window of as much snow or
ice as possible before using the rear window defogger.
To turn on the rear window defogger, find the switch
marked
REAR with the defog symbol on the lower right
corner of your climate control system. Press the button
until the light in the switch comes on, then release it.
It
will only work if the ignition switch is turned to RUN.
If your vehicle is equipped with the optional heated
outside rearview mirrors, the rear window defogger
button will activate the rear window defogger and the
heated outside rearview mirrors. The
rear window defogger will stay
on for five to seven
minutes, then turn
off. If you need additional warming
time, turn it
on again. You can turn the defogger off at
any time
by pressing the button.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid
on the rear window.
NOTICE:
Don’t use a razor blade or something else sharp
on the inside
of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn’t be covered by your warranty.

Downloaded from www.Manualslib.com manuals search engine Treadwear Temperature -- A, B, C
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions
on a specified government test course.
For example, a tire graded
150 would wear one and a
half
(1 1/2) times as well on the government course
as a tire graded
100. The relative performance of tires
depends upon the actual conditions
of their use,
however, and may depart significantly from the norm
due to variations in driving habits, service practices
and differences in road characteristics and climate.
Traction -- A, B, C
The traction grades, from highest to lowest, are A, B,
and C, and they represent the tire’s ability to stop on
wet pavement as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete.
A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to this tire is based
on braking (straight ahead) traction tests and does not
include cornering (turning) traction. The
temperature grades are
A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material
of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden tire
failure. The grade
C corresponds to a level of
performance which all passenger car tires must meet
under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
