Replacing the wiper blades
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

! 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.

Overview of climate control systems
General notes
The THERMATIC automatic climate control is
available with one or two climate control zones. As dual-zone automatic climate control, the
temperature can be regulated separately on the
driver's side and front-passenger side.
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 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 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 95). 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. Control panel for THERMATIC automatic climate control
