inside the vehicle will then be recirculated.
If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.

Switching the residual heat on or off
General notes
Vehicles with rear-compartment climate
control: once the engine is switched off, it is
possible to make use of the residual heat of the
engine to continue heating or ventilating the
rear and front compartment of the vehicle for
approximately 15 minutes. If the "Residual heat"
function is set for only the front or only the rear compartment, it is possible to continue heating
or ventilating for approximately 30 minutes.
Vehicles without rear-compartment climate
control: once the engine is switched off, it is
possible to make use of the residual heat of the
engine to continue heating or ventilating the
front compartment of the vehicle for approx-
imately 30 minutes.
The heating or ventilation time depends on the
temperature that has been set.

You can use the "Ionization" function to purify
the air in the vehicle interior and attain an
improved interior climate.
The ionization of the interior air is odorless and
cannot be perceived directly in the vehicle inte-
rior.
You can switch ionization on or off using the
multimedia system (see the separate operating
instructions).
Ionization can only be switched on if the front
climate control system is activated. The side air
vent on the driver's side must be open.
