if you keep your windaws closed while
using them. Your vehicle also has the
flow-through ventilation system
described later in this section.

: The left control knob sets the fan
speed. To select the force of air you want,
turn the knob. The fan is always running
unless the mode control is moved to OFF.

control regulates the temperature of the
air coming through the system.
Mode Control: The right knob changes
the functions of your system.
A.ir Conditioning
Your system has three air conditioner
settings. Before using your air conditioner
on
very
hot days, open the windows long
enough to let hot inside air escape. This
reduces the amount of work your air
conditioner's compressor will have to do,
which should help fuel economy.
MAX: Use for maximum cooling. This
setting recirculates much of the air inside
your vehicle
SO
it maximizes your air
conditioner's performance and your
vehicle's fuel economy. The air is directed
out through the instrument panel vents.
A/C: Use for normal cooling on hot days.
This setting cools outside air and directs it
through the instrument panel outlets.
h e
lH
(Bi-Level): Use on cool, but sunny
days. This setting brings in the outside air,
but directs it in two ways. The cool air is
directed to the upper portion of your body
through the instrument panel outlets, but
slightly warmer air is directed through the
heater ducts and defroster vents. At times
this temperature difference may be more
apparent than others.
The air conditioner compressor operates
in five air conditioning positions when the
outside temperature is higher than about
40°F (4.5"C).
The five positions for air conditioniqg are
MAX (Maximum), NORM (Normal.), B/L
(Bi-Level),
;j'
VENT and

(Defrost).
