Important safety notes G
WARNING
If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades. !
Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen.
Never fold a windscreen wiper arm without a
wiper blade back onto the windscreen.
Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release the
windscreen wiper arm without a wiper blade
and it falls onto the windscreen, the wind-
screen may be damaged by the force of the
impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. Otherwise, the windows could
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activate the "Windscreen demisting" function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The "Cooling with dehumidification" function is
available only when the engine is running. Opti-
mum climate control is achieved only with the
side windows and roof closed.
The residual heat function can be activated or
deactivated only with the ignition switched off
(Y page 135). The integrated filter filters out most particles of
dust and soot and completely filters out pollen.
It also reduces gaseous pollutants and odours. 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 Service Book-
let. As this depends on environmental condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Service Booklet.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 96). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i It is possible that the blower may be activa-
ted automatically 60 minutes after the key
has been removed depending on various fac-
tors, e.g. the outside temperature. The vehi-
cle is then ventilated for 30 minutes to dry the
automatic climate control.

mate control in the separate Owner's Manual. Control panel for THERMATIC automatic climate control

J To set the airflow (Y page 132) Notes on using automatic climate
control
Optimum use of automatic climate con-
trol The following contains notes and recommenda-
tions on how best to use THERMATIC automatic
climate control or THERMOTRONIC.
R Activate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with dehumidification" function is activated in
automatic mode.
R Set the temperature to 22 †.
R Use the "Windscreen demisting" function only
briefly until the windscreen is clear again.
R Use the "Air-recirculation mode" function only
briefly, e.g. if there are unpleasant outside
odours or when in a tunnel. The windows
could otherwise mist up as no fresh air is
drawn into the vehicle in air-recirculation
mode.
R Vehicles with THERMATIC with auxiliary heat-
ing or THERMOTRONIC: use 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
be switched on or off only with the ignition
switched off. The "Residual heat" function is
switched off when the ignition is switched on.
DYNAMIC SELECT switch (except
Mercedes-AMG vehicles) You can choose between various drive programs
with the DYNAMIC SELECT switch
(Y page 152).
If you have selected drive program E:
R during heating, the electrical heater booster
is deactivated and heat output is reduced as a
result
R the rear window heating running time is
reduced If you have selected drive program

ECO start/stop function During automatic engine switch-off, the climate
control operates only at a reduced capacity. If
you require the full climate control output, you
can switch off the ECO start/stop function by
pressing the ECO button (Y page 149). Operating the climate control system
Switching the climate control on/off
General notes When climate control is switched off, the air
supply and air circulation are also switched off.
The windows could mist up. Therefore, switch
off climate control only briefly.
Switch on climate control primarily using the
à rocker switch (Y page 131).
Activating/deactivating X
Turn the key to position 2in the ignition lock
(Y page 144).
X To switch on: set the airflow to level 1 or
higher using the Hrocker switch.
X To switch off:set the airflow to level 0 using
the H rocker switch.

Activating/deactivating cooling with air dehumidification
General notes If you deactivate the "Cooling with dehumidification" function, the air inside the vehicle will not be
cooled during warm weather. The air inside the vehicle will also not be dehumidified. The windows
can mist up more quickly. Therefore, deactivate the "Cooling with dehumidification" function only
briefly.
The "Cooling with dehumidification" function is available only when the engine is running. The air
inside the vehicle is cooled and dehumidified according to the temperature selected.
Condensation may drip from the underside of the vehicle when cooling mode is active. This is normal
and not a sign that there is a malfunction.

When the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.

Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle a maximum of two times, drive for a longer distance.
Switch the auxiliary heating on regularly – once a month – for about ten minutes.
The auxiliary heating heats the air in the vehicle
interior to the set temperature. This occurs with- out using the heat of the running engine. The
auxiliary heating is operated directly using the
vehicle's fuel. For this reason, the fuel tank level
must be above the reserve range to ensure that the auxiliary heating functions.
The auxiliary heating or auxiliary ventilation
automatically adjusts to changes in tempera-
ture and weather conditions. For this reason,
the auxiliary heating could switch from ventila-
tion mode to heating mode or from heating
mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventilation
is not active if the engine is running.
The auxiliary heating or auxiliary ventilation
switches off automatically after 50 minutes.
This time limit can be altered. To do this, consult
a qualified specialist workshop.
You cannot use the auxiliary ventilation to cool
the vehicle interior to a temperature lower than
the outside temperature.
Before switching on X
Turn the key to position 2in the ignition lock
(Y page 144).
X Set the desired temperature using the w
rocker switch on the front control unit.
If you do not alter the temperature before
switching on the auxiliary heating or auxiliary
ventilation, the last temperature setting will be
adopted.
Auxiliary heating or auxiliary ventilation can also be switched on if the manually set climate con-
trol is activated. Optimum comfort is attained
when the system is set to automatic mode. Set
the temperature to 22 †.
You can switch the auxiliary heating or auxiliary
ventilation on or off:
R using the rocker switch on the centre console
(Y page 138)
R using the remote control (Y page 139)The remote control can be used to set up to
three departure times, one of which may be pre- selected.

If the engine has not yet reached operating tem-
perature when it is started, the auxiliary heating running time is increased. The auxiliary heating
continues to run until the engine has reached its
operating temperature. If this is the case, the
y symbol appears on the remote control dis-
play and the running time is zero minutes.
Setting the departure time Make sure that the time set in the vehicle is
correct before setting the departure time (see
