OTHER CONTROLS AND EQUIPMENT
System operating instructions
Natural ventilation
Select VENTILATION and FRESH AIR, the
temperature selector to the desired tem-
perature position, and the blower speed
selector to off. Fresh air will flow through
the vehicle during driving.
Forced ventilation
The control settings are the same as for
natural ventilation except you set the
blower speed selector to a position other
than off.
Normal heating (using outside air)
Select HEAT and FRESH AIR, the tem-
perature selector to the desired tempera-
ture position and the blower speed selector
to the desired blower speed position. Set-
ting the blower speed selector to a higher
blower speed position increases heating
efficiency.
Quick heating (using recirculated air)
The control settings are the same as for
normal heating except you select RECIR-
CULATED AIR. If you use this heating
method for an extended period of time, the
air in the vehicle can become contami-
nated and the windows can become misty.
Therefore, use this method only for quick
heating and change to the normal heating
method as soon as possible.
5-19
Head cooled/Feet warmed heating
Select BI-LEVEL and FRESH AIR, the
temperature selector to the desired tem-
perature position, and the blower speed
selector to the desired blower speed posi-
tion. Unless the temperature selector is in
the fully cold position or fully hot position,
the air that comes out of the center and
side outlets will be cooler than the air that
comes out of the floor outlets.
Defrosting/Feet warmed heating
Select HEAT & DEFROST and FRESH
AIR, the temperature selector to the
desired temperature position, and the
blower speed selector to high. When the
windshield has become clear, set the
blower speed selector to the desired
blower speed position.
Defrosting
Select DEFROST and FRESH AIR, the
temperature selector to the desired tem-
perature position (higher temperature pro-
vides more efficient defrosting), and the
blower speed selector to high. When the
windshield has become clear, set the
blower speed selector to the desired
blower speed position.
EXAMPLE
NOTE:
If you need maximum defrosting, adjust
the temperature selector to hot end and
adjust the side outlets so the air blows on
the side window, in addition to the above
Defrosting procedure.
