Problems with the perfume atomiser
Problem
The vehicle interior is
not perfumed although
the perfume atomiser
has been 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 or off using
Audio 20 or COMAND Online (see the sepa-
rate operating 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 via key
General notes
The "Pre-entry climate control via key" func-
tion is only available in PLUG-IN HYBRID vehi-
cles.
Before getting in, the driver's seat area or the
whole interior can be briefly warmed or ven-
tilated in advance with the air from the air
vents being pre-cooled.
