3-1. Using the air conditioning system and defogger
Operating conditions
■
The Solar Ventilation System may not operate under the following circum-
stances due to a lack of power from the solar panel:
●
Low amount of sunlight
●
Ever when a part of the solar panel is cast by a shadow.
●
Ever when a part of the solar panel is covered by fallen leaves or dirt.
●
The solar panel is not at a high temperature.
Before using the Solar Ventilation System
■
Remove dirt or fallen leaves from the solar panel in order to ensure sufficient
electrical output.
Efficient use of the Solar Ventilation System
■
Efficient control of temperature increase can be achieved by using the sys-
tem in conjunction with the Remote Air Conditioning System. (P. 346)
When using the Solar Ventilation System
■
●
Make sure that the "POWER" switch is in ON mode when turning the
ventilation switch on. If the ventilation switch is turned on while the
"POWER" switch is OFF, the air mode and the status of the air vents will
remain unchanged.
●
If the Solar Ventilation System is not needed, be sure to turn the ventila-
tion switch off.
Dirty air and exhaust fumes from other vehicles may be drawn from out-
side. Also, use in winter may cause heated interior air to leave the vehi-
cle, thus leading to a drop in temperature.
Sounds when using the Solar Ventilation System
■
If the amount of sunlight is insufficient, you may hear a sound coming from
the air conditioning system. This is the sound of a control function to pre-
serve the fan and does not indicate a malfunction.
