Replacing bulbs (vehicles with LED
headlamps)
The front and rear light clusters of your vehicle
are equipped with light-emitting diodes. Do not
replace the vehicle's bulbs yourself. Contact a
qualified specialist workshop which has the nec-
essary specialist knowledge and tools to carry
out the work required.
Lamps are an important aspect of vehicle safety. You must therefore make sure that these func-
tion correctly at all times. Have the headlamp
setting checked regularly. Windshield wipers
Switching the windshield wipers
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. Combination switch

In the 0062or0063 position, the appropriate
wiping frequency is set automatically according
to the intensity of the rain. In the 0063position,
the rain sensor is more sensitive than in
the 0062 position, causing the windshield wiper
to wipe more frequently.
Vehicles with MAGIC VISION CONTROL: the
washer fluid is fed through the wiper blades and when wiping with washer fluid 00D4the washer
fluid is emitted directly from the blades.
If the wiper blades are worn, the windshield will no longer be wiped properly. This could prevent
you from observing the traffic conditions. Replacing the wiper blades
Important safety notes G
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. Windshield wipers

Always switch off the windshield wipers and
ignition before changing the wiper blades.
! Always position the windshield wiper arms
vertically before folding them away from the
windshield. By doing so, you will avoid dam-
age to the hood.
! To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the wiper.
! Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
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 spe-
cialist workshop.

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing 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 dehumidifica-
tion function
R Activate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The residual heat function can only be activated or deactivated with the ignition switched off
(Y page 123).
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 87). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly. If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (Y page 129).
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci-
fied.
i Vehicles with ionization of the interior
air with air filter: in addition to ionization,
the vehicle has an air filter with anti-allergenic properties that contribute to improved air fil-
tration.
i It is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-tilated for 30 minutes. Control panel for dual-zone automatic climate control
