Using a mobile phone
If the mobile phone is inserted in the mobile
phone bracket, you can speak to the person
you are calling using the hands-free system.
XOpen the telephone compartment
( Y page 270).XPlace the mobile phone bracket into the
pre-installed fitting (see the separate
installation instructions for the mobile
phone fitting).XInsert the mobile phone into the mobile
phone bracket (see the separate installa-
tion instructions for the mobile phone fit-
ting).
i On some mobile phone brackets, first you
have to connect the phone to the mobile
phone bracket via Bluetooth ®
(see the sep-
arate operating instructions for the mobile
phone bracket).
If this is the case, the mobile phone does
not have to be inserted into the bracket for
you to be able to use the telephone func-
tions. However, the charging function and
aerial function are not available.
Operating the mobile phone
You can operate the telephone using the
6 and ~ buttons on the multifunction
steering wheel. You can operate other mobile
phone functions via the on-board computer
( Y page 215).
When you remove the key from the ignition
lock, the mobile phone stays switched on.
However, you can no longer use the hands-
free system.
If you have an active call and would like to
take the key out of the ignition lock, first
remove the mobile phone from the bracket.
i If you use a mobile phone bracket which
is connected to your mobile via Blue-
tooth ®
and you wish to continue a call on
your mobile phone:
You should switch the call to "Private
mode" before you remove the key from the
ignition lock. Otherwise, it will take up to
20 seconds for the mobile phone to dis-
connect from the system. Only then can
you continue the call on your mobile phone.
Notes on the necessary steps for setting
"Private mode" can be found in the sepa-
rate operating instructions of the mobile
phone.
i Not all mobile phones support "Private
mode".
Mobile phone bracket in the stowage
space
You can fold the pre-installed bracket up to
improve access to the stowage space
beneath it. Depending on the vehicle's equip-
ment, a USB connection and an AUX-IN con-
nection/Media Interface are fitted in the
stowage compartment ( Y page 270).
XTo fold the bracket up: press button :.XTo fold the bracket down: press the
bracket down and allow it to engage.
Floormat on the driver's side
GWARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle
is jeopardised. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Fit the floormats

be checked more frequently if the vehicle is
operated under increased loads. Further
information can be obtained at a qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Mercedes-Benz Service24h" section
of the Service Booklet.
Care
General notes
HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
Care of the exterior
Automatic car wash
GWARNING
Braking efficiency is reduced after the vehicle
has been washed. There is a risk of an acci-
dent.
After washing the vehicle, brake carefully
while paying attention to the traffic conditions
in order to restore full braking efficiency.
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations. To prevent dam-
age to the vehicle, deactivate DISTRONIC
PLUS and the HOLD function in the follow-
ing or other similar situations:
R when towing the vehicle
R in the car wash
! Make sure that the automatic transmis-
sion is in position N when washing your
vehicle in a tow-through car wash. The vehi-
cle could be damaged if the transmission is
in another position.
! Make sure that:
R the side windows and sliding sunroof are
closed completely.
R the blower for the ventilation/heating is
switched off (OFF button is depressed/
airflow control is turned to position 0).
R the windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
Wash off excess dirt before cleaning the vehi-
cle in an automatic car wash.
288CareMaintenance and care
ProCarManuals.com

After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen.
Washing by hand
In some countries, washing by hand is only
allowed at wash bays that are specially
designed for this purpose. Observe the legal
requirements for each individual country.
XDo not use hot water and do not wash the
vehicle in direct sunlight.XUse a soft sponge to clean.XUse a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.XThoroughly hose down the vehicle with a
gentle jet of water.XDo not point the water jet directly towards
the air inlet.XUse plenty of water and rinse out the
sponge frequently.XRinse the vehicle with clean water and dry
thoroughly with a chamois.XDo not let the cleaning agent dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
High-pressure cleaning equipment
GWARNING
The water jet of circular-jet nozzles (dirt grind-
ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam-
aged tyres or chassis components replaced
immediately.
! Always maintain a distance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, roof gaps, joints etc.
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
Cleaning the wheels
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up.
Cleaning the paintwork
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
