climate settings MERCEDES-BENZ GL-Class 2016 X166 Owner's Manual

Useful information
i
This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.

ist workshops (

Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise 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 dehumidifi-
cation 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.
Climate control can only be operated when
the engine is running. Optimum operation is
only achieved with the side windows and roof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (
Ypage 159).
iVentilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (
Ypage 99).
This will speed up the cooling process and
the desired interior temperature will be
reached more quickly.
iThe integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants 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 Booklet.
iIt is possible that under certain circum-
stances the residual heat function may be
activated automatically an hour after the
SmartKey has been removed in order to dry the automatic climate control. The vehicle
is then ventilated for 30 minutes.

Optimum use of dual-zone climate
control
The following contains notes and recommen-
dations on optimum use of dual-zone climate
control.
RYou can switch on climate control by using
theà and¿ orà andÁ but-
tons. The indicator lamps in the Ãand
¿ buttons or the ÃandÁ but-
tons light up.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" func-
tion 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 oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
RUse the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp above the ábutton goes
out.
RVehicles with COMAND: if you change the
settings of the climate control system, the
climate status display appears for approx-
imately three seconds at the bottom of the
screen in the COMAND display (see sepa-
rate operating instructions). You will see
the current settings of the various climate
control functions.
During automa tic e
ngine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require the full cli-
mate control output, you can switch off the
ECO start/stop function by pressing the ECO
button (
Ypage 170).

Optimum use of 3-zone automatic cli-
mate control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your dual-zone automatic climate con-trol.
RYou can switch on climate control by using
the à and¿ orà andÁ but-
tons. The indicator lamps in the Ãand
¿ orà andÁ buttons light up.
RIn automatic mode, you can also use the
ñbutton to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM level is recommended.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" func-
tion 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 oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
RUse the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side and the rear com- partment as well. The indicator lamp above
the á button goes out.
RUse 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 only be activated or deac-
tivated with the ignition switched off.
RVehicles with COMAND: if you change the
settings of the climate control sy
stem, the
climate status display appears for approx-
imately three seconds at the bottom of the
screen in the COMAND display (see sepa-
rate operating instructions). You will see
the current settings of the various climate
control functions. During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require the full cli-
mate control output, you can switch off the
ECO start/stop function by pressing the ECO
button (
