Manual
Control
If you prefer to manually control the heating, cooling
and ventilation in your vehicle, set the system to the
temperature and fan speed you want. Next, push the
desired airflow direction pushbutton. The system will
try
to maintain the temperature you
set
using the mode
you select. The following suggestions will help the
system run more efficiently in manual mode.
Air Conditioning
On very hot days, open the windows long enough to
let hot, inside air escape. This reduces the time the
compressor has to run, which should help fuel economy.
For quick cool-down on very hot. days, use RECIRC.
If this setting is used for long periods of time, the air
in
your vehicle may become too dry.
For normal cooling on hot days, use UPPER with the
A/C
button pushed in. The system will bring in outside
air and cool
it.
Heating
On cold days, use LOWER. The system will bring
in
outside air, heat
it
and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it
to help your system provide warm air faster when it’s
cold outside
(0°F
(-18°C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in the Index.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use UPPER to direct outside air
through your vehicle. Your vehicle also has the
.
flow-through ventilation system, described later in
this section.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To
defrost the windows quickly, use DEF.
To
warm passengers while keeping the windows clean,
use DEFOG.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use
BI-LEV
with the A/C button pushed in.
