Climate Control System
qWindshield Defrosting and Defogging
Set the mode selector dial to the
position and turn the fan control dial to
the desired speed.
The outside air position is automatically
selected. The air conditioner will
automatically turn on and direct
dehumidified air to the front windshield
and side windows.
WARNING
Set the temperature control to hot or
warm position when using the
position:
Using the position with the
temperature control set to the cold
position is dangerous as it will cause
the outside of the windshield to fog
up. Your vision will be hampered,
which could lead to a serious
accident.
NOTE
Use the temperature control dial to increase
the air flow temperature and defog the
windshield more quickly.
qSunlight/Temperature Sensor
The automatic air conditioner function
measures inside and outside temperatures,
and sunlight. It then sets temperatures
inside the passenger compartment
accordingly.
CAUTION
Do not obstruct either sensor,
otherwise the automatic air
conditioner will not operate properly.
