Conditioning Controls
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.
OFF:
Press to turn the system off. Some
air will still come from the outlets at the
floor. Press any function button to turn the
system on.
Temperature Control Lever: This lever
changes the temperature of the air coming
through the system. The farther the lever
is to the right, the warmer the air.
3f
: Selects the force of air you want.
Press to lower the fan speed,
A
to raise
it.
Air Conditioning (A/C)
For each setting, set the temperature
control lever to a comfortable setting.
There are three air conditioning settings:
MAX: Provides maximum cooling or
quick cool-down on very hot days. This
setting recirculates much of the air inside
your vehicle, and it should not be used for
long periods because the air may become
too cold and dry.
A/C: Use for normal cooling on hot days.
This setting brings in outside air, cools it
and directs it through the instrument panel
outlets.
BI-LEV 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
most warmed air is directed through the
heater ducts and a little to the defrost and
side window vents. At times this
temperature difference may be more
apparent than others.
On very hot days, open the windows long
enough to let hot inside air escape. This
reduces the time your air conditioner's
compressor will have to run, which
should help fuel economy.
The air conditioner compressor operates
in all three air conditioning settings. It
also operates in "BLEND' and
(Defrost) when the temperature is above
freezing. This helps remove moisture
from the air inside your vehicle.
Heating and Ventilation
When you don't need to cool the outside
air, use these next settings. You can leave
the air as it is or heat
it.
For each setting,
set the temperature to a comfortable
temperature setting.
The air conditioner compressor doesn't
run in the "VENT" and "HEAT" settings.
This reduces the engine load, resulting in
improved fuel economy (gas mileage).
VENT For mild outside temperatures,
when little heating or cooling is needed,
push VENT. Air flow is through the
instrument panel outlets. Slide the
temperature control lever to a comfortable
level.
