Replacing bulbs
The front and rear light clusters of your vehi-
cle are equipped with LED light bulbs. Do not
replace the bulbs yourself. Contact a qualified
specialist workshop which has the necessary
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 function 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 collected 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 wind-
shield wipers.
!If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid

after washing the vehicle in an automatic
car wash.
!Vehicles with a rain sensor: if the wind-
shield becomes dirty in dry weather condi- tions, the windshield wipers may be activa-
ted 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.

Ypage 151).
XTurn the combination switch to the corre-
sponding position.
In the ÄorÅ position, the appropriate
wiping frequency is set automatically accord-
ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive
than in the Äposition, causing the wind-
shield wipers to wipe more frequently.
The washer fluid is fed through the wiper
blades; when the screen is wiped with washer
fluid î, the water is emitted directly from
the blades. If you push and hold the combination switch
beyond the point of resistance in the direction
of arrow
B, the manual wash program is
activated. If you push and hold the combina-
tion switch briefly beyond the point of resist-
ance in the direction of arrow B, the auto-
matic wash program is activated.
If the wiper blades are worn, the windshield
will no longer be wiped properly. This could
prevent you from observing the traff ic c
ondi-
tions.
Replacing the wiper blades
Important safety notes
GWARNING
If the wind shield wipers begin to move while
you are changing the wiperblades, you could
be trapped by the wiper arm. There isa risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!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.
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.
!Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood.

Useful information
i
This Operator's Manual describes all
models and all standard and optional equip-
ment 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.

ist workshops (
Ypage 26).
Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise fog up.
To prevent the windows from fogging up:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only
briefly
Rswitch on the cooling with air dehumidifi-
cation function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and air humidity in the vehicle interior. The air
filter cleans the air, thus improving the inte-
rior climate.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. Optimum climate control is only ach-
ieved with the side windows and roof closed.
If you start the engine using your smartphone,
the last selected climate control setting is
reactivated (
Ypage 154).
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (
Ypage 143).
iVentilate the vehicle for a brief period
during warm weather, e.g. using the con- venience opening feature (
Ypage 99). This
will speed up the cooling process and the
desired interior temperature will be
reached more quickly.
iThe integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol- lutants and odors. 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 Maintenance
Booklet. As it depends on environmental
conditions, e.g. heavy air pollution, the
interval may be shorter than stated in the
Maintenance Booklet.
iIt is possible that the blower may be acti-
vated automatically 60 minutes after the
SmartKey has been removed depending on various factors, e.g. the outside tempera-
ture. The vehicle is then ventilated for
30 minutes t
o dry the climate control sys-
tem.

trol
General notes
When the climate control is switched off, the
air supply and air circulation are also
switched off. The windows could fog up.
Therefore, switch off climate control only
briefly
Switch on climate control primarily using the
à rocker switch (
Ypage 139).
Activating or deactivating
XTurn the SmartKey to position 2in the igni-
tion lock (
Ypage 151).
XTo activate: press thetrocker switch

Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc-
tion.
Activating or deactivating
XTo activate: press theÁrocker switch
up or down.
The indicator lamp above the rocker switch
lights up.
or
XActivate the "Cooling with air dehumidifi-
cation" function via COMAND (see the sep-
arate operating instructions).
XTo deactivate: press theÁrocker
switch up or down.
