Independent ventilation
Principle
The independent ventilation system ventilates
the passenger compartment and lowers its
temperature where required.
General
The independent ventilation can be switched
on and off via two preselected switch-on times
or directly. The system remains switched on
for 30 minutes.
The independent ventilation is operated using
iDrive.
Operating requirements
▷ Direct operation: vehicle is in radio ready
state.

Air conditioning
Online Edition for Part no. 01402981699 - VI/17
▷ Direct operation or preselected switch-on
time: does not depend on the outside tem‐
perature.
▷ Battery is sufficiently charged.
The vehicle battery is discharged when the
independent ventilation is switched on. As
a result, the maximum activation time is re‐
stricted to protect the battery. After the en‐
gine is started or after driving a short dis‐
tance, the system will be available again.
▷ Ensure that the data and time are set cor‐
rectly in the vehicle.
▷ Open the ventilation vents to allow the air
to enter the passenger compartment.
