Introduction

are used to help in finding malfunctions and
improving quality and are sent to the manufac-
turer where necessary. In addition, the manu-
facturer is subject to product liability. The man-
ufacturer needs technical data from vehicles for
this purpose.
Malfunction memories in the vehicle can be
reset by a service center during repair or service
work.
You can incorporate data into the vehicle's com-
fort and infotainment functions yourself as part
of the selected equipment.
These include, for example:
Rmultimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
Raddress book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
Rnavigation destinations that have been
entered
Rdata about using Internet services
These data can be saved locally in the vehicle or
are located on a device that you have connected
to the vehicle. If this data is saved in the vehicle,
you can delete it at any time. These data are sent
to third parties only at your request, particularly
when you use online services in accordance with
the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the piece of equipment in ques-
t

ion, these can include, for example:
Rseat and steering wheel position settings
Rsuspension and climate control settings
Rcustom 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:
Rgeneral vehicle information
Rposition 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.
Service provider
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 enabled by either an in-vehicle
transmitter and receiver or your own mobile end
device (e.g. smartphone). Online functions can
be used via this wireless network connection.
These include online services and applications/ Apps provided 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 and the associated informa-
tion subject to data protection legislation. Per-
sonal data can be used in order to provide online
services. Data are exchanged via a secure con-
nection (e.g. using the IT system specially pro-
vided for this purpose by the manufacturer).
Collecting, processing and using personal data
beyond the provision of services is permitted
only on the basis of a statutory permit or decla-
ration of consent.
You can usually activate and deactivate the serv-
ices and functions (some of which are subject to
charge). In many cases, this also applies to the
vehicle's entire data connection. However, this
does not apply in particular to legally prescribed
functions 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.

240Care
Maintenance and care

The electrolyte of the battery is cor-
rosive. Avoid contact with skin, eyes
or clothing.
Wear suitable protective clothing,
especially gloves, apron and face-
guard.
Immediately rinse electrolyte
splashes off with clean water. Con-
tact a physician if necessary.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehicle
occupants from suffering acid burns should the
battery be damaged in the event of an accident.
In order for the battery to achieve the maximum
possible service life, it must always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.
In this case, have the battery disconnected at a
qualified specialist workshop. You can also
charge the battery with a special charger rec-
ommended by Mercedes-Benz. Contact a quali- fied specialist workshop for further information.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly for
short trips or if you leave it standing idle for a
lengthy period. Consult a qualified specialist
workshop if you wish to leave your vehicle
parked for a long period of time.
When you use the SmartKey in the ignition and
you park the car, remove the SmartKey if you do not require any electrical consumers. The vehi-
cle will then use very little energy, thus conserv-
ing battery power.
If the power supply has been interrupted, e.g. if
you reconnect the battery, you will have to:
Rreset the function for automatically folding
the exterior mirrors in/out by folding the mir-
rors out once (
Ypage 92)
Rreset the side windows, see (Ypage 78)
Charging the battery
!
Only use battery chargers with a maximum
charging voltage of 14.4 V.
!Only charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment (
Ypage 254).
XOpen the hood.
XConnect the battery charger to the positive
terminal and ground point in the same order
as when connecting the donor battery in the
jump-starting procedure (
Ypage 254).
Keep away from fire and open flames. Do not
lean over a battery. Never charge the battery if it
is still installed in the vehicle, unless you use a
battery charger which has been tested and
approved by Mercedes-Benz. A battery charger
unit specially adapted for Mercedes-Benz vehi-
cles and tested and approved by Mercedes-
Benz is available as an accessory. It permits the
charging of the battery in its installed position.
Contact an authorized Mercedes-Benz Center
for further information and availability. Read the
battery charger's operating instructions before
charging the battery.
Do not charge a battery which has been
removed at low temperatures with a battery
charger. Allow the battery to warm up gently
first, if necessary. Otherwise, the service life can
be shortened and the starting characteristics
impaired, especially at low temperatures.
Jump-starting
XFor the jump-starting procedure, use only the jump-starting connection point in the engine com- partment, consisting of a positive terminal and a ground point.
