You can incorporate data into the vehicle's com-
fort and infotainment functions yourself as part
of the selected equipment.
These include, for example:
R Multimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
R Address book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
R Navigation destinations that have been
entered
R Data about using Internet services
This data can be saved locally in the vehicle or
located on a device that you have connected to the vehicle (e.g. smartphone, USB memory stick
or MP3 player). If this data is saved in the vehi-
cle, you can delete it at any time. This data is
sent to third parties only at your request, par-
ticularly when you use online services in accord- ance with the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the equipment in question, these can include:
R Seat and steering wheel position settings
R Suspension and climate control settings
R Custom settings such as interior lighting
If your vehicle is equipped appropriately, you
can connect your smartphone or another mobile
end device to the vehicle. You can control this by
means of the control elements integrated in the vehicle. The smartphone's picture and sound
can be output via the multimedia system. Spe-
cific items of information are also sent to your
smartphone.
Depending on the type of integration, this can
include:
R General vehicle information
R Position data
This allows the use of selected smartphone
apps, such as navigation or music player apps.
There is no additional interaction between the
smartphone and the vehicle, particularly active
access to vehicle data. The type of additional
data processing is determined by the provider of
the app being used. Whether you can configure settings for it and, if so, which ones, depends on
the app and your smartphone's operating sys-
tem. Online services
Wireless network connection If your vehicle has a wireless network connec-
tion, data can be exchanged between your vehi-
cle and other systems. The wireless network
connection is made possible by the vehicle's
own transmitter and receiver or by mobile devi- ces that you have brought into the vehicle (e.g.
smartphones). Online functions can be used via
this wireless network connection. These include online services and applications/apps providedby the manufacturer or other providers.
Services provided by the manufacturer In the case of the manufacturer's online serv-
ices, the manufacturer describes the functions
in a suitable place (e.g. operating instructions,
manufacturer's website) and provides the asso-
ciated information subject to data protection
legislation. Personal data can be used in order to
provide online services. The exchange of data
for this purpose takes place via a secure con-
nection, e.g. with the manufacturer's IT systems intended for the purpose. Collecting, processing
and using personal data beyond the provision of
services is permitted only on the basis of a stat-
utory permit or declaration of consent.
You can usually activate and deactivate the serv-
ices and functions (sometimes subject to a fee).
In many cases, this also applies to the vehicle's entire data connection. However, this does not
apply in particular to legally prescribed func-
tions and services such as the "eCall" emer-
gency call system.
Services from third parties If it is possible to use online services from other
providers, these services are the responsibility
of the provider in question and subject to that
provider's data protection conditions and terms of use. The manufacturer has no influence over
the content exchanged here.
For this reason, please ask the service provider
for information about the type, extent and pur-
pose of the collection and use of personal data
when services are provided by third parties. 30

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.
! Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
high-pressure cleaner nozzle. Information
about the correct distance is available from
the equipment manufacturer.
Move the power washer nozzle around when
cleaning your vehicle.
Do not aim directly at any of the following:
R tires
R door gaps, joints etc.
R soft top
R wind deflector net
R electrical components R
battery
R plug-type couplings

243Maintenance and care Z

!
Do not use chrome polish on trim pieces.
The trim pieces have a chrome look but are
mostly made of anodized aluminum and can
lose their shine if chrome polish is used. Use
a damp, lint-free cloth instead when cleaning the trim pieces.
If the chrome-plated trim pieces are very
dirty, you can use a chrome polish. If you are
unsure as to whether the trim pieces are
chrome-plated or not, consult an authorized
Mercedes-Benz Center.
X Wipe the trim elements with a damp, lint-free
cloth, e.g. a microfiber cloth.
X Heavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
Cleaning the seat covers General notes
! Do not use a microfiber cloth to clean covers
made out of real leather, artificial leather or
DINAMICA. If used often, these can damage
the cover.
i Note that regular care is essential to ensure
that the appearance and comfort of the cov-
ers is retained over time.
Genuine leather seat covers ! To retain the natural appearance of the
leather, observe the following cleaning
instructions:
R Clean genuine leather covers carefully with
a damp cloth and then wipe the covers
down with a dry cloth.
R Make sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
R Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a qualified
specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
R differences in the texture
R marks caused by growth and injury
R slight nuances of color
These are characteristics of leather and not
material defects. Seat covers of other materials
! Observe the following when cleaning:
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid).
R clean cloth covers with a microfiber cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning results
depend on the type of dirt and how long it
has been there.
R clean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
Cleaning the seat belts G
WARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event of an accident. This poses an increased risk of
injury or fatal injury.
Never bleach or dye the seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts by
heating at temperatures above 176 ‡(80 †)
or in direct sunlight.
X Use clean, lukewarm water and soap solution.
Cleaning the carpets X
Use the carpet and textile cleaning agents
recommended and approved by Mercedes-
Benz. 248
CareMaintenance and care

!
Secure the tow rope or tow bar to the towing
eye only. Otherwise, the vehicle could
become damaged.
! 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
! Do not use the towing eyes for recovery pur-
poses as this could damage the vehicle. If in
doubt, recover the vehicle with a crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
! Shift the automatic transmission to position
005C and do not open the driver's or front-
passenger door when towing the vehicle
away. Otherwise, the automatic transmission may shift to position 005Dwhich can cause
damage to both vehicles.
! Do not tow with sling-type equipment. This
could damage the vehicle.
! You may tow the vehicle for a maximum dis-
tance of 30 miles (50 kilometers). A towing
speed of 30 mph (50 km/h) must not be
exceeded.
For towing distances over 30 miles
(50 kilometers), the entire vehicle must be
raised and transported.
! Observe the transmission fluid temperature
(AMG menu) in the on-board computer when
towing. The transmission oil temperature
must not exceed 250 ‡ (120 †). If this
occurs, you must stop towing immediately.
! Tow-starting the vehicle is not permitted.
The transmission may otherwise be damaged.
Also observe the following notes:
R If the engine does not start, try jump-starting
it (Y page 256). Tow-starting the vehicle is not
permitted.
R If it is not possible to jump-start the vehicle,
have it transported to the nearest qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Service Center. If the vehicle can no longer be driven because of
an accident or breakdown, you have the follow- ing options:
R Transporting the vehicle.
As a rule, you should have the vehicle trans-
ported.
R Towing the vehicle with a tow rope or tow bar.
Only tow the vehicle in exceptional cases. The
engine must be running if you tow the vehicle with a tow rope or tow bar.
If the vehicle has suffered transmission damage, have it transported on a transporter or trailer.
Observe the display messages in the instrument
cluster.
The battery must be connected and charged.
Otherwise, you:
R will not be able to switch on the ignition with
the Start/Stop button
R cannot start the engine
R cannot release the electric parking brake.
R cannot shift the automatic transmission to
position 005C
Disarm the automatic locking feature before the vehicle is towed (Y page 73). You could other-
wise be locked out when pushing or towing the
vehicle. Permitted towing methods
Mercedes-Benz recommends transporting your
vehicle in the case of a breakdown, rather than
towing it away.
When towing away, use a towing rope or a tow-
ing bar with both axles on the ground. Do not use any tow bar systems. Installing/removing the towing eye
Installing the towing eye The bracket for the screw-in towing eye is
behind the radiator trim.
