Automatic interior lighting control
X
To switch on or off: press the0033button.
When the automatic interior lighting control is
activated, the button is flush with the over-
head control panel.
The interior lighting automatically switches on if you:
R unlock the vehicle
R open a door
R switch off the engine with the Start/Stop but-
ton
The interior lighting is activated for a short time
when the engine is switched off with the Start/ Stop button. This delayed switch-off can be
adjusted via the multimedia system (see Digital
Operator's Manual). Replacing bulbs
The front and rear light clusters of your vehicle
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 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 offthe windshield wipers in dry weather. 0047

X Switch on the ignition.
X Turn the combination switch to the corre-
sponding position.
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.
The rain sensor is only an aid. The driver is
responsible for ensuring unimpaired vision. Turn
the switch to a suitable position, depending on
the intensity of the precipitation, to ensure that a good view of the traffic conditions is main-
tained.
If the wiper blades are worn, the windshield willno longer be wiped properly. This could preventyou from observing the traffic conditions.
Worn or damaged wiper blades cause smearing. This can cause the rain sensor to malfunction 100

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.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! 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.
! To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
wiper.
Replacing the wiper blades Adjusting the wiper blades so that they
are vertical
X Switch off the engine.
X Remove your foot from the brake pedal. X

drive for a few minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a
long period of time.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents recom-
mended and approved by Mercedes-Benz. Washing the vehicle and cleaning the
paintwork
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
! When Active Brake Assist, Active Distance
Assist DISTRONIC or the HOLD function is
activated, the vehicle brakes automatically in
certain situations.
To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
R when towing the vehicle
R in the car wash
! Preferably use automatic car washes with
adjustable high-pressure pre-cleaning. This
corresponds with the specification for the
Cabriolet program. In car washes that use
high water pressures, there is a risk that a
small amount of water may leak into the vehi- cle.
! Make sure that the vehicle is not subse-
quently treated with hot wax.
! Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If you have your vehicle cleaned in a high-
pressure automatic car wash, small amounts of water may enter the vehicle. !
If the SmartKey is within the rear detection
range of KEYLESS-GO, the following situa-
tions, for example, could lead to the uninten-
tional opening of the trunk lid:
R when using an automatic car wash
R when using a power washer
Make sure that the SmartKey is at least 10 ft
(3 m) away from the vehicle.
! Make sure that:
R the side windows are fully closed
R the blower of the ventilation/heating sys-
tem is switched off
R the windshield wiper switch is at position
003F
R the rear-view camera is deactivated
The vehicle may otherwise be damaged.
! When washing your vehicle in a tow-through
car wash, use the SmartKey instead of the
Start/Stop button.
Start the engine using the SmartKey. Set the
transmission to 005Cwith the E-SELECT selec-
tor lever. Switch the engine off again with the SmartKey by turning the SmartKey to position
0048. Make sure that you then leave the Smart-
Key in position 0048. You may otherwise dam-
age the vehicle, the transmission or the car
wash.
Check the transmission position in the instru-
ment cluster.
! Before switching off the engine, use the
E‑SELECT lever to shift the transmission to
005C. If you open the driver's or front-passenger
door, the transmission remains in this posi-
tion for up to 30 minutes if the key is in the
ignition, even if the engine is switched off. If
you do not shift the transmission to 005Cusing
the E‑SELECT lever beforehand, it shifts auto-
matically to parking position 005Dand locks the
wheels if the driver's or front-passenger door
is opened when the engine is switched off.
This may damage the vehicle, the transmis-
sion or the car wash.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off wax from the windshield and the wiper blades. This
will prevent smears and reduce wiping noises
caused by residue on the windshield. 242
CareMaintenance and care

i
Have work or repairs on decorative film car-
ried out at a qualified specialist workshop.
Mercedes-Benz recommends that you use an authorized Mercedes-Benz Center for this
purpose. Cleaning the vehicle parts
Cleaning the wheels G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park your vehicle for a long period of
time directly after cleaning, particularly after
cleaning the wheel rim with wheel cleaner.
Wheel cleaner can lead to the increased cor-
rosion of the brake discs and pads. Therefore,
drive for a few minutes after cleaning. By
heating up the brakes, the brake discs and
pads dry. The vehicle can then be parked for a long period of time.
Cleaning the windows G
WARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Do
not touch the insides of the windows with hard objects, e.g. an ice scraper or ring. There
is otherwise a risk of damaging the windows.
! Clean the water drainage channels of the
windshield and the rear window at regular
intervals. Deposits such as leaves, petals and pollen may under certain circumstances pre-
vent water from draining away. This can lead
to corrosion damage and damage to elec-
tronic components.
X Clean the inside and outside of the windows
with a damp cloth and a cleaning product that
is recommended and approved by Mercedes-
Benz.
Cleaning the soft top !
Never use any of the following to clean the
soft top:
R gasoline
R thinner
R tar or stain remover
R other organic solvents
! Remove bird droppings immediately, as
they are corrosive and can therefore cause
the soft-top fabric to leak. Do not wash the
vehicle with a power washer or in a car wash
that uses power washers. Do not use sharp-
edged equipment to remove ice and snow.
X Light soiling: you can clean the soft top while
it is dry or rinse it with clear water.
X Normal to heavy soiling: clean the soft top
with a brush and clear water. Clean stains and other dirt with a brush and soft top cleaning
agents that have been recommended and
approved by Mercedes-Benz. Always brush
from front to back, following the grain of the
fabric.
Frequent cleaning reduces the soft top's resist- ance to dirt.
To restore this resistance to dirt, clean the soft
top using soft top cleaning agents that have
been recommended and approved by
Mercedes-Benz.
Incorrect cleaning and care, as well as aging,
can cause the soft-top seams to leak. In the
event of this happening, have the soft-top seams
sealed at a qualified specialist workshop.
i Cover the soft top appropriately if you plan
to leave the vehicle outside for a long period
of time. Care
