CLIMATE CONTROLS
Manual Air Conditioning and Heating System Ð If
Equipped
The controls for the heating/air conditioning and venti-
lation system in this vehicle consist of a series of rotary
knobs. These comfort controls can be set to obtain desired
interior conditions.
The instrument panel features four dual-vane airflow
registers. Two registers are located on the outer ends of
the instrument panel and two are located in the center of
the instrument panel. These registers can be closed to
partially block airflow, and they can be adjusted to direct
airflow where the occupant desires.

located on the control panel. Conditioned air will be
directed through the outlets selected by the mode control.
A light in the snowflake button shows that the air
conditioning is on.
Slight changes in engine speed or power may be noticed
when the air conditioning compressor is on. This is a
normal occurrence as the compressor will cycle on and
off to maintain comfort and increase fuel economy.
Automatic Temperature Control Ð If Equipped
The Infrared Dual-Zone Climate Control System auto-
matically maintains the interior comfort level desired by
the driver and passenger. This is accomplished by a dual
sun-sensor in the top of the instrument panel, and an
infrared sensor located in the face of the control unit.
There are also various sensors monitored by this system
which take account for vehicle speed, A/C pressure,
outside temperature, and engine cooling temperature.
The infrared sensor independently measures the surfacetemperature of the driver and passenger. Based on the
sensor input, the system automatically adjusts the air
flow temperature, the air flow volume, and amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.

The system will automatically control recircu-
lation. However, pressing this button will tem-
porarily put the system in recirculation mode.
This can be used when outside conditions such
as smoke, odors, dust, or high humidity are present. This
will cause the LED to illuminate.
NOTE:
²The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor's location.
Mud on the windshield may also cause poor operation
of this system.
²To provide you with maximum comfort in the auto-
matic mode, during cold start-ups the blower fan will
remain off until the engine warms up. However, the
fan will engage immediately if the defrost mode is
selected or if you manually select a blower speed.
²Under certain conditions (after the vehicle is turned
off) the climate control system may recalibrate and a
noise may be heard for 20 seconds. This is part of
normal operation.
²Most of the time, when in Automatic operation, you
can temporarily put the system into recirculation
mode by pressing the Recirc button. However, under
certain conditions in automatic the system is blowing
air out of the defrost vents. When these conditions are
present and the Recirc button is pressed the indicator
will flash and remain off. This tells you that you are
unable to go into recirculation mode at this time. If you
would like to go to Recirculation mode, you must first
move your mode knob to panel, panel/floor or floor,
then hit the Recirc button. This feature will reduce the
possibility of window fogging.

Rear Climate Control Ð If Equipped
The Manual Rear Climate Control system has one floor
air outlet (passenger side), and two panel outlets in the
rear quarter trim (on each side). The unit provides warm
or cool air through the floor and upper outlets.
If rear heating/cooling is desired, press the ªRear On/Off
Switchº (located in the upper switch bank above the
controls) and select ªFloorº ªBi-Levelº or ªPanelº from
the Rear Control Panel (right knob located on the right
rear quarter trim panel).

The rear temperature, blower speed, and mode control can
be adjusted as desired by the third row seat occupants.
NOTE:The rear climate control system cannot be con-
trolled from the front seat; it can only be turned on and
off. All control of the rear system must be performed by
the rear occupants.
Rear Blower Control
The left knob on the Rear Control Panel has four posi-
tions, ªOffº, and a range of three blower speeds. This
allows the third row seat occupants to control the volume
of air circulated in the rear of the vehicle.
CAUTION!
Interior air enters the Manual Rear Zone Climate
Control system through an intake grille located in the
passenger side trim panel behind the third seat. The
heater outlets are located in the passenger side trim
panel just behind the sliding door. Do not block or
place objects directly in front of the inlet grille or
heater outlets. The electrical system could overload
causing damage to the blower motor.

TIRE QUALITY GRADES
The following describes the tire grading categories estab-
lished by the National highway Traffic Safety Adminis-
tration. The specific grade rating assigned by the tire's
manufacturer in each category is shown on the sidewall
of the tires on your car.
All Passenger Car Tires Must Conform to Federal Safety
Requirements in Addition to These Grades.
Treadwear
The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled con-
ditions on a specified government test course. For ex-
ample, 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, andmay depart significantly from the norm due to variations
in driving habits, service practices and differences in road
characteristics and climate.
Traction Grades
The traction grades, from highest to lowest, are AA, A, B,
and C. Those grades 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 perfor-
mance.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
