– Dust and pollen is filtered out from the
inflowing air.
– Nano-particle emissions are reduced.
– Gaseous pollutants are filtered.
– Microbial particles, viruses and aller-
gens are filtered.
The manufacturer of the vehicle recom-
mends having the interior filter changed
during vehicle maintenance.
Pre-ventilation
Principle
Pre-ventilation is used to cool or heat the
vehicle interior before beginning a drive.
The vehicle interior is ventilated or heated
as necessary using residual engine heat, de-
pending on the set temperature and ambi-
ent temperature.
The system can be switched on and off di-
rectly or via a preset departure time.
The activation time is determined based
on the outside temperature. The system
promptly switches on before the selected
departure time.
The system switches off automatically after
a certain period of time. The system con-
tinues to run for some time after being
switched off.
Functional requirements
The following functional requirements apply
for pre-ventilation:
– The vehicle is in idle state or standby
state.
– The vehicle battery is sufficiently
charged.
If pre-ventilation is switched on, the ve-
hicle battery will be discharged. Thus,
limit the maximum activation time to
save the vehicle battery. System can be
used again once engine is started or af-
ter a short drive.
– Time and date are set correctly.
– The ventilation air vents are open.
Turning pre-ventilation on/off
Pre-ventilation can be turned on/off using
the Interaction Unit:
1. Select the Climate menu icon on
the menu bar.
2. Tap the settings button.
3. "Pre-ventilation"
4. Select the desired setting.
Departure time
Principle
Different departure times can be set to en-
sure a comfortable interior temperature in
the vehicle at the time of departure:
– One-time departure time: the time can
be set.
The system is switched on once.
– Departure time with weekday: Time and
day of week can be set.
On the desired weekdays, the system
will be switched on before the set depar-
ture time.
The departure time is preselected in two
steps:
– Set the departure time.
– Activate departure times.
Allow for at least 10 minutes between set-
ting and activating the departure time and
departing at the planned time. This gives
the air conditioning sufficient time to pre-
pare the vehicle interior.
