■Efficient use of the So lar Ventilation System
Efficient control of temperature increase can be achieved by using the sys-
tem in conjunction with the Remote Air Conditioning System. ( P. 285)
■ 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.
■ When using the Sola r 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.
● Remove dirt or fallen leaves from the solar panel in order to ensure suffi-
cient electrical output.
● If the Solar Ventilation System is not needed, be sure to turn the ventila-
tion switch off, otherwise the following problems may occur:
• Dirty air and exhaust fumes from ot her vehicles may be drawn from
outside.
• Use in winter may cause heated interior air to leave the vehicle, thus leading to a drop in temperature.
■ Noises 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.
