The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle also
has the flow-through ventilation system described later in
this
section.
Lever Controls: The upper lever changes the functions
of
your system. The lower lever changes the temperature
of the air coming through the system.
3f
: Selects the force of air you want.
Air Conditioning
The upper lever has three air conditioner settings. 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.
M A X : Provides maximum cooling with the least amount
of work. This setting recirculates much of the air inside
your vehicle
so
it maximizes your air conditioner's
performance and fuel economy.
NORM (Normal): Use for normal cooling on hot days.
This setting cools outside air and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use this on cool, but sunny days.
This setting brings in the outside air, but directs it in tw
ways. The cool air
i s
directed to the upper portion of
your body through the instrument panel outlets, but
warmed air is directed through the heater ducts and
defroster vents. At times this temperature difference may
be more apparent than others.
To turn the 5x1 off, move the upper lever to the
OF'F position.
