WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk
of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.

make sure that you touch only the wiper
arm of the wiper.

arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.

arms vertically before folding them away
from the windshield. By doing so, you will

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment 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.
i Read the information on qualified
specialist workshops: (Y page 33).Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could
otherwise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air
dehumidification function
R switch 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
activated or deactivated with the ignition
switched off (Y page 150).
i When the weather is warm, ventilate the
vehicle for a brief period. This will speed up
the cooling process and the desired vehicle
interior temperature will be reached more
quickly. i
It is possible that the dehumidification
function of the climate control system may
be activated automatically an hour after the
SmartKey has been removed. The vehicle
is then ventilated for 30 minutes to dry the
air-conditioning system. 140
