Air Conditioning
On hot days, open the windows long enough to let hot
inside
air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
If you have the standard system, for quick cool-down on
very hot days,
use MAX with the temperature knob in
the blue area. If this setting is used for long periods of
time, the air in your vehicle may become too cold and
dry. For normal cooling on hot days, use A/C with the
temperature
knob in. the blue area. This setting cools the
air entering your vehicle and directs it through the
instrument panel outlets.
If you have the electronic system, press the A/C button
to
turn the system on. The system will cool and
dehumidify the air inside the vehicle.
Also while in
AUTO mode, the system will use FtECIRC as necessary
to cool the air.
&1 cool but sunny days, with the standard system through
manual operation of the electron& system, use BI-LEVEL
to deliver warm air to the floor and cooler air to the
middle instrument panel outlets. To warrn or cool the
air
delivered, push the TE- button up or down.
When the air conditioner is on, you may sometimes notice
slight changes
in your vehicle’s engine speed and power.
This is normal because the system is designed to cycle the
cornpressor on
and off to keep the desired temperature.
