Climate control
▷
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.
