Optimum use of automatic climate
control
Optimum use of automatic climate con-
trol
The following contains notes and recommenda-
tions on how best to use dual-zone automatic
climate control or 3-zone automatic climate
control.
XActivate climate control using the Ã
rocker switch. The indicator lamp above the Ã
rocker switch lights up. The "Cooling
with dehumidification" function is activated in
automatic mode.
XSet the temperature to 72 ‡ (22 †).
iOnly use the "Windshield defrosting" func-
tion briefly until the windshield is clear again.
iOnly use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or when
in a tunnel. The windows could otherwise fog
up, since no fresh air is drawn into the vehicle in air-recirculation mode.
120Overview of climate control systems
Climate control

Vehicles with 3-zone automatic climate control:
use the "Residual heat" function if you want to
heat or ventilate the vehicle interior when the
ignition is switched off. The residual heat func-
tion can only be activated or deactivated with
the ignition switched off. The residual heat func-
tion is deactivated when the ignition is switched
on.
DYNAMIC SELECT switch (except
Mercedes-AMG GLC 63 4MATIC/
GLC 63 S 4MATIC)
You can choose between various drive programs
with the DYNAMIC SELECT switch
(
Ypage 138).
If you have selected drive program E:
Rwhen heating, the electrical heater booster is
deactivated and heat output is reduced as a
result
Rthe rear window defroster running time is
reduced
If you have selected drive program C,Sor S+,
the current climate settings are maintained.
ECO start/stop function
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
Ypage 136).

Ionization
Ionization is used 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/off using the mul-
timedia system (
Ypage 271).
Ionization can only be operated when the auto-
matic climate control is switched on. The side air
vent on the driver's side must be open.
Air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet between the windshield and
the hood free of blockages, such as ice, snow
or leaves.
Rnever cover the air vents or air intake grilles in
