J To set the airflow (Y page 132) Notes on using automatic climate
control
Optimum use of automatic climate con-
trol The following contains notes and recommenda-
tions on how best to use THERMATIC automatic
climate control or THERMOTRONIC.
R Activate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with dehumidification" function is activated in
automatic mode.
R Set the temperature to 22 †.
R Use the "Windscreen demisting" function only
briefly until the windscreen is clear again.
R Use the "Air-recirculation mode" function only
briefly, e.g. if there are unpleasant outside
odours or when in a tunnel. The windows
could otherwise mist up as no fresh air is
drawn into the vehicle in air-recirculation
mode.
R Vehicles with THERMATIC with auxiliary heat-
ing or THERMOTRONIC: use the "Residual
heat" function if you want to heat or ventilate
the vehicle interior when the ignition is
switched off. The "Residual heat" function can
be switched on or off only with the ignition
switched off. The "Residual heat" function is
switched off when the ignition is switched on.
DYNAMIC SELECT switch (except
Mercedes-AMG vehicles) You can choose between various drive programs
with the DYNAMIC SELECT switch
