Windshield wipers
Switching the windshield wipers
on/off
!
Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use washer fluid when operating the wind-
shield wipers.
!If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.

For this reason, you should always switch

Notes on using the air-conditioning
system
Air-conditioning system
Below, you can find a number of notes and
recommendations to help you use the air-
conditioning system optimally.
RSwitch on the air-conditioning system by
turning 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
dehumidification function (
Ypage 138).
Set air distribution to ¯and if possible
switch off PandO (
Ypage 140).
Deactivate air-recirculation mode e
(
Ypage 143).
Set airflow control Ato a setting between
3 and 6(
Ypage 140).
RRecommendation for rapid cooling or
heating of the vehicle interior: briefly set
airflow control Ato a setting between 3
and 6(
Ypage 140).
RRecommendation for a constant vehi-
cle interior temperature: set airflow con-
trol Ato a setting between 1and 3
(
Ypage 140).
RRecommendation for air distribution in winter: select the Oand¯ settings
(
Ypage 140).
Recommendation for air distribution in
summer: select the PorP and
¯ settings (
Ypage 140).
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 outsid e od
ors 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.
RIf you change the settings of the climate
control system, the climate status display
appears for approximately three seconds
at the bottom of the screen in the Audio/
COMAND display (see separate operating
instructions). You will see the current set-
tings of the various climate control func-
tions.
DYNAMIC SELECT button (except
Mercedes-AMG vehicles)
You can choose between various drive pro-
grams with the DYNAMIC SELECT button
(
Ypage 157).
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, the climate
settings can also be influenced in drive pro-
gram I.
If you have selected drive program Cor S, the
climate settings are not affected.
ECO start/stop function
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 (

Setting climate control to automatic
General notes
The automatic function is only available in
conjunction with dual-zone automatic climate
control.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore, only
deactivate the "Cooling with air-dehumidifi-
cation" function briefly.
