This system uses the automatic climate
control system blower to ventilate the
passenger compartment and reduce interior
temperatures while the vehicle is
parked.
The independent ventilation system is
operated via the Multi-Information Display
(MID) or the onboard computer.
Refer to the separate Owner's Manual.
You can preselect the activation time
for a 30-minute ventilation cycle, or you
can switch the system on and off manually
with the ignition key at position 1.
Since the system uses a substantial
amount of electrical current, you should
refrain from activating it twice in succession
without allowing the battery to
be recharged in normal operation between
use.
When a preselected activation time is
set, the independent ventilation system
is operational at outside temperatures
above 607 (166), or by direct switch
activation. It cannot be switched on
when the vehicle is moving.
The air emerges via the vent outlets for
the upper body. Therefore, the vents
must be open for the system to operate.
