Solar panel*
A solar panel is available in combination 
with the panorama sliding / pop-up roof. 
The solar cells convert natural light into 
electrical energy. When the engine is 
switched off, the energy generated auto-
matically switches on the ventilation fan. 
The constant air flow creates a cooler tem-
perature for cars parked in the sunlight.
The air flow depends on the intensity of the 
solar radiation. The ventilation starts two 
minutes after switching off the engine.
