Introduction

In some countries, certain parts are only offi-
cially approved for installation or modification
if they comply with legal requirements. All gen-
uine Mercedes-Benz parts satisfy these
requirements. Make sure that all parts are
suitable for your vehicle.
Always specify the vehicle identification num-
ber (VIN) ( Y page
304) and engine number
when ordering genuine Mercedes-Benz parts
(Y page 305). QR code for rescue card
The QR Code stickers are affixed to the B-pillar
on the driver's and front-passenger side.
In the event of an accident the rescue services
use the QR Code to quickly find the rescue
card for your vehicle. The current rescue card
contains the most important information on
your vehicle, e.g. the electric cable routes, in a
compact form.
Further information can be found at http://
www.mercedes-benz.de/qr-code. Data stored in the vehicle
Electronic control units
Electronic control units are installed in your
vehicle. Some of them are necessary to ensure
that your vehicle functions safely, some are
there to support the driver (driver assistance
systems). In addition to that, your vehicle
offers convenience and entertainment func-
tions which are also made possible by the use
of electronic control units.
Electronic control units contain data memories
which can store technical information on the
vehicle's operating state, component stress,
maintenance requirements as well as technical
events and malfunctions either temporarily or
permanently.
In general, this information documents the sta-
tus of a component, a module, a system or the
surroundings, for example:
R operating states of system components (e.g.
fill levels, battery status, tire pressure)
R status messages concerning the vehicle or
its individual components (e.g. number of
wheel revolutions/speed, deceleration in movement, lateral acceleration, display of
fastened seat belts)
R malfunctions and defects in important sys-
tem components (e.g. lights, brakes)
R information on events damaging the vehicle
R system responses in special driving situa-
tions (e.g. air bag deployment, intervention
of stability control systems)
R ambient conditions (e.g. temperature, rain
sensor)
In addition to the underlying control unit func-
tion, this data can be used for the detection
and the rectification of malfunctions as well as
the optimization of vehicle functions by the
manufacturer. Most of this data is volatile and
is only processed in the vehicle itself. Only a
small proportion of the data is stored in event
or malfunction memories.
When you use services, the technical data
from the vehicle can be read out by service
network employees (e.g. workshops, manufac-
turers) or third parties (e.g. breakdown serv-
ices). Services can include repair services,
maintenance processes, warranty cases and
quality assurance measures. Data is read out
using the legally prescribed diagnostics con-
nection in the vehicle. The respective repre-
sentatives of the service network or third par-
ties collect, process and use the data. It docu-
ments technical states of the vehicle, helps
staff to find malfunctions and improve quality
and, in certain cases, is passed on to the man-
ufacturer. Furthermore, the manufacturer is
subject to product liability provisions. For this
reason, the manufacturer requires technical
data from vehicles.
Malfunction memories in the vehicle can be
reset within the scope of the repair or service
work carried out by a service outlet.
Depending on the equipment selected, you
can add data to the convenience and infotain-
ment functions of the vehicle yourself.
These include:
R multimedia data, such as music, films or
photos for playback in an integrated multi-
media system
R address book data for use in connection
with an integrated hands-free system or an
integrated navigation system
R navigation destinations entered
R data on the utilization of Internet services Introduction
35 Z

This data can be saved locally in the vehicle or
is located on a device that you have connected
to the vehicle (e.g. smartphone, USB flash
drive or MP3 player). If this data is saved in
the vehicle, you can delete it at any time.
Transfer of this data to third parties is only
possible at your request, predominantly while
using online services and in accordance with
the settings you have selected.
You can save convenience settings/customi-
zations in the vehicle and change them at any
time.
Depending on the piece of equipment in ques-
tion, these can include:
R settings for the seat and steering wheel
positions
R suspension and air-conditioning settings
R customizations 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
operate this device using the integrated con-
trols in the vehicle. This allows images and
sound from the smartphone to be output
through the multimedia system. Simultane-
ously, certain information is transferred to
your smartphone.
Depending on the type of integration, this can
include:
R general vehicle status
R position data
This allows the use of selected smartphone
apps, such as navigation or music player apps.
No further interaction between smartphone
and vehicle takes place and, in particular, it is
not possible to actively access vehicle data.
The type of additional data processing is deter-
mined by the provider of the app being used.
Which settings can be made, if at all, depend
on the respective app and the operating sys-
tem of your smartphone. Online services
Wireless network connection If your vehicle has a wireless network connec-
tion, data can be exchanged between your
vehicle and other systems. The wireless net-
work connection is made possible by the vehi-
cle's own transceiver or by mobile end devices
that you have brought into the vehicle (e.g. smartphones). This wireless network connec-
tion can be used to access online functions.
This includes online services and apps provi-
ded by 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. manufacturer's operat-
ing instructions, website) and provides the
associated information subject to data protec-
tion legislation. Personal data may be used
when providing online services. The data
exchange for this takes place via a secure con-
nection, e.g. with the manufacturer's IT sys-
tems intended for the purpose. The collection,
the processing and the use of personal data
above and beyond the provision of services is
only permitted on the basis of a legal permit or
the consent of the person involved.
In most cases, you can enable or disable the
services and functions, some of which are sub-
ject to a charge. In some cases it will also
apply to the entire data connection of the vehi-
cle. There are exceptions to this; in particular,
legally prescribed functions and services such
as the "E-Call" traffic emergency call system.
Services provided by third parties If it is possible to use online services from
other providers, these services are the respon-
sibility 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 in this
connection.
Please ask the respective service provider for
information on the type, extent and purpose of
the collection and use of personal data in the
context of services provided by third parties.36
Introduction

Problems with the tailgate
The tailgate cannot be opened.
The voltage supply has been interrupted or the
battery charge is insufficient.
Consult a qualified specialist workshop which
has the necessary specialist knowledge and
tools to carry out the work required.
In an emergency, you can open the tailgate
using the release catch for service purposes.
X Pry off the cover on the lower part of the
tailgate with a suitable tool, e.g. the screw-
driver from the vehicle tool kit.
X Insert the screwdriver into the opening and
move the release lever until the tailgate
unlocks and opens.
X Swing the tailgate upwards. Rear-end doors
Important safety notes
G
DANGER
Combustion engines emit poisonous
exhaust gases, such as carbon monoxide.
Exhaust gases can enter the vehicle interior
if the rear-end door is open when the engine
is running, especially if the vehicle is in
motion. There is a risk of poisoning.
Always switch off the engine before opening
the rear-end door. Never drive with the rear-
end door open. G
WARNING
If you open a rear door, you could:
R endanger other people or road users
R be caught by oncoming traffic
This is particularly the case if you open the
rear door more than 90°. There is a risk of
an accident and injury.
Only open the rear doors when traffic condi-
tions permit. Always make sure that the rear
doors are properly locked. G
WARNING
If you open the rear-end doors 90°, the rear
lighting systems are no longer visible. The
vehicle will then be difficult for other road
users to see or will not be seen by them at
all, particularly if it is dark or visibility is
poor. There is a risk of an accident.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant
national regulations, by using the warning
triangle, for instance.
! Make sure that there is sufficient clear-
ance when opening the rear doors. You
could otherwise damage the vehicle and
objects in close range of the rear doors.
You can lock the rear-end doors at an angle of
approx. 90° and, if necessary,
180° or 270°.
Always make sure that the open rear-end door
is correctly engaged in the detent. Opening and closing from the out-

cally if you engage reverse gear and the wind-
shield wipers are on.
If the vehicle is stationary and you open the
tailgate or rear-end door, the rear window
wiper will stop automatically. The rear window
wiper will only resume wiping again when the
tailgate and rear-end door are closed and you
pull away again.
The rear window will no longer be wiped prop-
erly if the wiper blade is worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blade can be found under "Replacing wiper blades"
(
Y page

110). 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/tailgate or rear
doors if a windshield wiper arm has been
folded away from the windshield/rear win-
dow.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
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/rear
window, the windshield/rear window 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.
! Only hold the wiper blade by the wiper
arm. You could otherwise damage the wiper
rubber.
Wiper blades are wear parts. The windshield
will no longer be wiped properly if the wiper
blades are worn. This may prevent you from
observing the traffic conditions.
Please observe the service indicator after
changing the wiper blades of the windshield
wiper.
Service indicator Replacement wiper blades for the windshield
wiper have a service indicator on the tip of the
wiper blade.
Depending on the amount of use, the service
indicator will change color from black to yel-
low.110
