CONTROLS
▷ Gaseous pollutants are filtered.
▷ Microbial particles, viruses and allergens
are filtered.
The manufacturer of the vehicle recommends
having the interior filter changed during vehicle
maintenance.
Pre-ventilation
Principle
The car's interior can be cooled or heated
before driving off with the pre-ventilation. De-
pending on set temperature and ambient tem-
perature, the car's interior is ventilated or pos-
sibly heated using the residual engine heat.
General information
The system can be switched on and off directly
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 continues to
run for some time after being switched off.
Functional requirements
▷ The vehicle is in idle state or standby state.
▷ The vehicle battery is sufficiently charged.
If pre-ventilation is switched on, the vehicle
battery will be discharged. Thus, limit the
maximum activation time to save the vehi-
cle battery. The system will be available
again after the engine is started or after a
short trip.
▷ Time and date are set correctly.
▷ The ventilation air vents are open.

Departure time
Principle
Different departure times can be set to ensure
a comfortable interior temperature in the vehi-
cle 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 the week can be set.
On the desired weekdays, the system will
be switched on before the set departure
time.
The departure time is preselected in two steps:
▷ Set departure times.
▷ Activate departure times.
A minimum of 10 minutes should pass be-
tween setting and activating the departure
time and the planned departure time to allow a
sufficient period of time for the climate control.
