of these outlets can be individually adjusted to direct the
flow of air. Moving the air vane knob on the center
outlets down, will close off the air flow from the center outlets. The thumbwheel next to the outboard outlets can
be rotated to regulate or shut off the air flow from these
outlets.

outlets and defrost. A slight amount of air is also directed
through the side window demister outlets. UNDERSTANDING YOUR INSTRUMENT PANEL 211

NOTE: In many temperature positions, the bi-level
mode is designed to provide cooler air out of the panel
outlets and warmer air from the floor outlets.
Floor Mode
Air comes from the floor outlets. A slight amount of air is
directed through the defrost and side window demister
outlets. Mix Mode
Air comes from the floor, defrost and side window
demist outlets. This mode works best in cold or snowy
conditions. It allows you to stay comfortable while keep-

Auxiliary Rear Automatic Temperature Control Ð
If Equipped
The Rear Automatic Temperature Control System has
floor air outlets to the rear of the right side sliding door
and overhead outlets at each outboard rear seating
position. The unit provides heated air through the floor
outlets or cool, dehumidified air through the headliner
outlets.
The ªREAR SYSTEMº knob for the Rear Automatic
Temperature Control System is on the front ATC control
unit located on the instrument panel.
Selecting the ªAUTOº position for the Rear Automatic
Temperature Control System from the front ATC control
unit, illuminates a ªLOCKº symbol in the rear display.
The rear temperature and air source are controlled from
the front ATC control unit. The ªREAR SYSTEMº knob on the front ATC control unit
has three positions, ªREAR CONTROLº, ªOFFº, and
ªAUTOº. Only when the ªREAR SYSTEMº knob is in the
ªREAR CONTROLº position do the second seat occu-
pants have control of the Rear Automatic Temperature
Control System.
The Rear Automatic Temperature Control System is
located in the headliner near the center of the vehicle.214 UNDERSTANDING YOUR INSTRUMENT PANEL

Operation of the rear system is quite simple. Begin by
rotating the rear system center control knob on the front
ATC control unit to the ªREAR CONTROLº position, this
illuminates an ªUNLOCKº symbol in the rear display.
Next, rotate the Rear Blower Control and the Rear Mode
Control to the ªAUTOº positions. Select the temperature
you would like the system to maintain by pressing the
Rear Temperature Control button. Once the desired tem-
perature is displayed, the system will achieve and main-
tain that comfort level automatically. When the system is
set up for your comfort level, it is not necessary to change
the settings. You will experience the greatest efficiency by
simply allowing the system to function automatically.
NOTE:
² It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible. ² The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.
Refer to the ªOverhead Console-Customer Program-
mable Featuresº in Section 3 of this manual.
Rear Blower Control
The rear blower control, located in
the headliner near the center of
the vehicle has an ªOFFº,
ªAUTOº and a range of blower
speeds.
The rear blower control knob can be manually set to
ªOFFº or any fixed blower speed by rotating the knob
from low to high. This allows the rear seat occupants to
control the volume of air circulated in the rear of the
vehicle. UNDERSTANDING YOUR INSTRUMENT PANEL 215

CAUTION!Interior air enters the Rear Automatic Temperature
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.
Rear Temperature Control
To change the temperature in the rear of the vehicle, press
the temperature control button down for cold and up for
heated air. Rear Mode Control
The Rear Mode Control, located in
the headliner near the center of
the vehicle can be used to select
between Auto, Headliner, Bi-
Level and Floor modes.
Auto Mode
The rear system automatically maintains the correct
mode and comfort level desired by the rear seat occu-
pants.
Floor Mode
Air comes from the floor outlets.216 UNDERSTANDING YOUR INSTRUMENT PANEL

Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE: In many temperature positions, the bi-level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Headliner Mode
Air comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vane knob on the outlets to
one side will shut off the air flow.
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene glycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.
Winter Operation
The air from the heater system will heat faster in cold
weather if you use only low blower speeds for the first 10
minutes of vehicle operation. Use of the air Recirculation
mode during winter months is not recommended be-
cause it may cause window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again. UNDERSTANDING YOUR INSTRUMENT PANEL 217
