climate settings MERCEDES-BENZ GLS-Class SUV 2017 X166 Owner's Manual

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 133).
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 87).
This will speed up the cooling process and the
desired interior temperature will be reached
more quickly. If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Ypage 140).
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book-
let.
iVehicles with AIR-BALANCE package: in
addition to ionization, the vehicle has an air
filter with anti-allergenic properties that con-
tribute to improved air filtration.
iIt is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey
has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-
tilated for 30 minutes.

Optimum use of automatic climate
control
Optimum use of the automatic climate
control
The following contains notes and recommenda-
tions on optimum use of the dual-zone or 3-zone
automatic climate control.
RYou can switch on climate control by using the
à and¿ orà andÁ buttons.
The indicator lamps in the Ãand
¿ buttons or the ÃandÁ buttons
light up.
RVehicles with 3-zone climate control: in
automatic mode, you can also use the
ñ button to set a climate mode (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly 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.
RVehicles with 3-zone climate control: use
the ZONE function to adopt the temperature
settings on the driver's side for the front-
passenger side and the rear compartment as
well. The indicator lamp above the ábut-
ton goes out.
RVehicles with 3-zone climate control: use
the "residual heat" function if you want to heat
or ventilate the vehicle interior when the igni-
tion is switched off. The residual heat function can only be activated or deactivated with the
ignition switched off.
RIf you change the settings of the climate con-
trol system, the climate status display
appears for approximately three seconds at
the bottom of the screen in the multimedia
system display. You will see the current set-
tings of the various climate control functions.
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 143).
