Windshield wipers
Switching the windshield wiper
on/off
!
Do not operate the windshield wipers when
the windshield is dry, as this could damage
the wiper blades. Moreover, dust that has col-
lected 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 windshield
wipers.
!If the windshield wipers leave smears on the
windshield after the vehicle has been washed
in an automatic car wash, wax or other resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Intermittent wiping with rain sensor: due to
optical influences and the windshield becom-
ing dirty in dry weather conditions, the wind-
shield wipers may be activated inadvertently.
This could then damage the windshield wiper
blades or scratch the windshield.
For this reason, you should always switch off
the windshield wipers in dry weather.

to low sensitivity)

XTurn the key to position 1or 2in the ignition
lock.
XTurn the íwiper switch to the corre-
sponding position.
In the ÄorÅ positions, the appropriate
wiping frequency is set automatically according
to the intensity of the rain. In the Åposition,
the rain sensor is more sensitive to precipitation
than in the Äposition, causing the wind-
shield wipers to wipe more frequently.
The windshield will no longer be wiped properly
if the wiper blades are worn. This may prevent
you from observing the traffic conditions. Infor-
mation on replacing the wiper blades can be
found under "Replacing wiper blades"
(
Ypage 107).

then also shows the èsymbol for vehicles
with steering wheel buttons (
Ypage 186).
XTo wipe with washer fluid: press theè
switch beyond the current position as far as it
will go to 1or press and hold 4.
When you release the èswitch, the rear
window wiper continues to wipe for about
another five seconds. The rear window wiper
then wipes according to the original position
2 or3.
The rear window wiper switches on automati-
cally if you engage reverse gear and the wind-
shield wipers are on.
If the vehicle is stationary and you open the tail-
gate or rear door, the rear window wiper will
stop automatically. The rear window wiper will
only resume wiping again when the tailgate and
rear door are closed and you pull away again.
The rear window will no longer be wiped properly if the wiper blade is worn. This may prevent you
from observing the traffic conditions. Informa-
tion on replacing the wiper blade can be found
under "Replacing wiper blades" (
Ypage 107).
Replacing the wiper blades
Important safety notes
GWARNING
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.
!Never open the hood/tailgate or rear doors
if a windshield wiper arm has been folded
away from the windshield/rear window.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
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/rear window,
the windshield/rear window 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.
!Only hold the wiper blade by the wiper arm.
You could otherwise damage the wiper rub-
ber.
Wiper blades are wear parts. The windshield will
no longer be wiped properly if the wiper blades
are worn. This may prevent you from observing
the traffic conditions.
Please observe the service indicator after
changing the wiper blades of the windshield
wiper.
Service indicator
Replacement wiper blades for the windshield
wiper have a service indicator on the tip of the
wiper blade.
Depending on the amount of use, the service
indicator will change color from black to yellow.
Change the wiper blade if:
Rthe wiper blade is damaged
Rthe service indicator has turned yellow
In order to activate the service indicator, you
have to remove the protective film
(
Ypage 107).

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Overview of climate control systems
Important safety notes
Observe the recommended settings on the fol-
lowing pages. Otherwise, the windows could fog
up.
To prevent the windows from fogging up:
Ronly switch off climate control briefly
Ronly switch on air-recirculation mode briefly
Rfor vehicles with air-conditioning system or
dual-zone automatic climate control, switch
on the "Cooling with air dehumidification"
function
Rfor vehicles with dual-zone automatic climate
control, switch on the windshield defrosting
function briefly, if requiredClimate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
Ventilate the vehicle for a brief period during
warm weather. In order to cool the vehicle more
rapidly, switch climate control to air-recircula-
tion mode briefly. This will speed up the cooling
process and the desired interior temperature
will be reached more quickly.
The integrated filter can filter out most particles
of dust and completely filters out pollen. In vehi-
cles with dual-zone automatic climate control,
gaseous pollutants and odors will also be
reduced. A clogged filter reduces the airflow into
the vehicle interior. For this reason, you should
always observe the interval for replacing the fil- ter, which is specified in the Maintenance Book-
let. As the interval between changes depends on
environmental conditions, e.g. heavy air pollu-
tion, the interval may be shorter than stated in
the Maintenance Booklet.
