set to low sensitivity)3Å Intermittent wipe, high (rain sensor
set to high sensitivity)4° Continuous wipe, slow5¯ Continuous wipe, fastBí Single wipe/ î to wipe the wind-
screen using washer fluidXTurn the key to position 1 or 2 in the ignition
lock.XTurn the combination switch to the corre-
sponding position.
! Vehicles with a rain sensor: if the wind-
screen becomes dirty in dry weather con-
ditions, the windscreen wipers may be acti-
vated inadvertently. This could damage the
windscreen wiper blades or scratch the
windscreen.
For this reason, you should always switch
off the windscreen wipers in dry weather.
Vehicles with a rain sensor: in the Ä or
Å position, the appropriate wiping fre-
quency is automatically set according to the
intensity of the rain. In the Å position, the
rain sensor is more sensitive than in
the Ä position, causing the windscreen
wipers to wipe more frequently.
If the wiper blades are worn, the windscreen
will no longer be wiped properly. This could
prevent you from observing the traffic condi-
tions. Replace the wiper blades twice a year,
ideally in spring and autumn.
Replacing the wiper blades
Important safety notesGWARNING
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.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
! 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
windscreen may be damaged by the force
of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.

Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.
R never cover the vents or ventilation grilles
in the vehicle interior.
i Move the adjusters for the air vents ver-
tically or horizontally, to set the direction of
the airflow.
i Optimal climate control function is ach-
ieved by opening the air vents fully and set-
ting the adjusters to the middle position.
Setting the centre air ventsXTo open the centre air vent: turn the
adjuster in one of centre air vents : anti-
clockwise.XTo close the centre air vent: turn the
adjuster in one of centre air vents : clock-
wise until it engages.Adjusting the air vents141Climate controlZ
