General notes
You can also temporarily deactivate the flow of
fresh air manually if unpleasant odors are enter-
ing the vehicle from outside. The air already
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.

tion lock (Ypage 136).
XTo activate: press thegrocker switch up
or down.
The indicator lamp above the grocker
switch lights up.

Rafter approximately five minutes if cooling
with air dehumidification is deactivated
Rafter approximately 30 minutes at outside
temperatures above approximately 41 ‡

function is activated
Switching the residual heat on or off
General notes
The residual heat function is only available with
3-zone automatic 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 com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the interior temperature that has
been set.
