Rear ventilation 
Use the lever1 to vary the airflow direction. 
For additional information on rear ventila-
tion options, refer to page106. 
Independent ventilation 
System operation is controlled using the 
Control Center. You can set two different 
times for the system to start. 
The independent ventilation blows air into 
the passenger compartment to lower inte-
rior temperatures.
The system remains on for 30 minutes. You 
can also switch the system on and off man-
ually. Since the system uses a substantial 
amount of electrical current, you should 
refrain from activating it twice in succes-
sion without allowing the battery to be 
recharged in normal operation between 
use. 
The independent ventilation is available for 
preprogrammed operation at outside tem-
peratures above approx. 59 7/156 and 
for direct activation at any temperature, but 
is not operational when the vehicle is 
underway. 
The air enters the passenger compartment 
through the vent outlets in the dashboard, 
which can be adjusted for both direction 
and airflow. These outlets must be open for 
the system to operate.
