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
The air-conditioning system or dual-zone auto-
matic climate control regulates the temperature and the humidity of the vehicle interior and fil-
ters undesirable substances from the air.
The air-conditioning system or dual-zone auto-
matic climate control can only be operated
when the engine is running. Optimum operation
is only achieved with the side windows and pan- orama roof with power tilt/sliding panel closed.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Ypage 84).
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 121). Always keep the ventilation flaps behind the
side trim panel in the cargo compartment clear
(
Ypage 107). Otherwise the vehicle will not be
ventilated correctly.
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 84). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
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.
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 aut
o-
matic climate control. The vehicle is then ven-
tilated for 30 minutes.

Notes on using the air-conditioning
system
Air-conditioning system
Below, you can find a number of notes and rec-
ommendations to help you use the air-condi-
tioning system optimally.
RSwitch on the air-conditioning system by turn- ing control knob Aclockwise to the desired
position (except position 0).
RSet the temperature to 72 ‡ (22 †).
RRecommendation for avoiding misted
windows at low exterior temperatures or
in rain: switch on the ¿cooling with dehu-
midification function (
Ypage 117).
Set air distribution to ¯and if possible
switch off PandO (
Ypage 118).
Deactivate air-recirculation mode e
(
Ypage 121).
Set airflow control Ato a setting between 3
and 6(
Ypage 119).
RRecommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3and
6 (
Ypage 119).
RRecommendation for a constant vehicle
interior temperature: set airflow controlA
to a setting between 1and 3(
Ypage 119).
RRecommendation for air distribution in
winter: select the Oand¯ settings
(
Ypage 118).
Recommendation for air distribution in
summer: select the PorP and¯
settings (
Ypage 118).
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 tu
nnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
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 on the multimedia
system display; see Digital Operator's Man-
ual. You will see the current settings of the
various climate control functions.
DYNAMIC SELECT button (except
Mercedes-AMG vehicles)
You can choose between various drive programs
with the DYNAMIC SELECT button
(
Ypage 130).
If you have selected drive program E:
Rwhen heating, the electrical heater booster is
deactivated and in the warming-up phase
heat output is reduced
Rthe rear window defroster running time is
reduced
Depending on the configuration, climate set-
tings may also be influenced in the drive pro-
gram I.
If you have selected drive program Cor S, cli-
mate settings are not influenced.
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 129).

Optimum use of dual-zone automatic
climate control
Climate control system
The following contains instructions and recom-
mendations to enable you to get the most out of
your dual-zone automatic climate control.
RActivate climate control using the Ãand
¿ buttons. The indicator lamps in the
à and¿ buttons light up.
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.
RUse the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side as well. The indicator
lamp in the
ábutton 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 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 on the multimedia
system display; see Digital Operator's Man-

General notes
If you deactivate the "Cooling with air-dehumid-
ification" function, the air inside the vehicle will
not becooled. The air inside the vehicle willalso
not be dehumidif ied. The windows can fog up
more quickly. Therefore, only deactivate the
"Cooling with air-dehumidif ication" function
briefly.
The "Cooling with air dehumidif ication" function
is only availab lewhen the engine isrunning. The
air inside the vehicle iscooled and dehumidif ied
according to the temperature selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.
