Problems with the perfume atomiser
Problem
The vehicle interior is
not perfumed although
the perfume atomiser is
activated.
Ionisation
Ionisation is used to purify and freshen the air
in the vehicle interior, which is conducive to a
pleasant climate.
The ionisation of the interior air is odourless
and cannot, directly, be perceived in the vehi-
cle interior.
You can switch ionisation on/off using Audio
20/COMAND Online (see the separate oper-
ating instructions).
Ionisation can only be operated when the
automatic climate control is switched on. The
side air vent on the driver's side must be
open.
Pre-entry climate control
General notes
The pre-entry climate control function is only
available for hybrid vehicles.
Before getting in, the driver's seat area can be
briefly warmed or ventilated in advance and
the air from the air vents can be pre-cooled.
