Electronic Solar Sensor
The sensor monitors the sun's solar radiation and is
located near the end of the instrument panel near
the windshield.
The climate control panel uses this information to
automatically make the necessary temperature and
airflow adjustments to maintain your comfort. The
climate control system may supply cooler air to one side
of your vehicle, if that side is facing the sun. Be careful
not to put anything over the sensor on top of the
instrument panel.

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. Your A/C setting
may be adjusted automatically or manually. It may also
be set separately on the passenger's side from the
driver's side. See "Climate Control Panel" earlier in
this section.
Heating
Adjust the interior temperature to a comfortable level
and if the fan speed needs adjusting, press the up or
down arrow. Adjusting the fan speed will cancel the cold
air delay.
Outside air will be brought in and sent through the floor,
-
air conditioning or bi level outlets. The heater works
best if you keep your windows closed while using it.
In automatic operation, your fan will not run at high
-
speed to minimize warm up time.
