Air quality
General
The air quality in the interior is improved by the
following components:
▷ Emissions-tested interior.
▷ Interior filter.
▷ Climate control system for regulating tem-
perature, amount of air and air recirculation
function.
▷ Pre-cooling.
Interior filter
The interior filter cleans the incoming outside
air or the circulated inside air in air recirculation
mode.
Depending on the equipment:
▷ Dust and pollen are filtered out from the
inflowing outside air.
▷ Nano-particle emissions are reduced.
▷ Gaseous pollutants are filtered.
▷ Microbial particles, viruses, and allergens
are filtered.
The vehicle manufacturer recommends having
the interior filter replaced when the vehicle is
serviced.
Pre-cooling
Principle
The pre-cooling allows the temperature of the
interior to be adjusted even before the start of
the journey. Depending on the set temperature
and ambient temperature, the interior is venti-
lated or heated using any available residual
heat from the engine.
General
The system can be switched on and off directly
or for a preselected departure time.

Air conditioning
The switch-on time is calculated based on the
outside temperature. The system will switch
on in good time before the preselected depar-
ture time.
The system switches off automatically after a
while. It continues to run for a short time after it
has been switched off.
Operating requirements
▷ The vehicle is in rest state or standby state.
▷ The vehicle battery must be sufficiently
charged.
When activated, the pre-cooling uses
power from the vehicle battery. As a result,
the maximum operating time is restricted to
protect the vehicle battery. After the engine
is started or after driving a short distance,
the system will be available again.
▷ Time and date are set correctly.
▷ The air vents of the ventilation are open.

Departure time
General
To ensure a pleasant interior temperature in
the vehicle at the start of the journey, it is pos-
sible to set different departure times.
▷ One-off departure time: the time can be set.
The system is activated once.
▷ Departure time with day of the week: the
time and day of the week can be set.
The system is switched on before the set
departure time on the required days of the
week.
