QR codes for the rescue card
The QR codes are secured in the fuel filler flap
and on the opposite side on the B-pillar. In the
event of an accident, rescue services can use
the QR code to quickly find the appropriate res- cue card for your vehicle. The current rescue
card contains the most important information
about your vehicle in a compact form, e.g. the
routing of the electric cables.
You can find more information at
www.mercedes-benz.de/qr-code .
Data stored in the vehicle
Information from electronic control
units
There are electronic control units installed in
your vehicle. Some of these are necessary for
your vehicle to operate safely, while some offer
support during driving (driver assistance sys-
tems). In addition, your vehicle offers comfort
and entertainment functions that are also made
possible by electronic control units.
Electronic control units contain data storage
systems that can temporarily or permanently
save technical information concerning the vehi-
cle's condition, component stress and mainte-
nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the
surroundings, for example:
Roperating states of system components (e.g.
fill levels, battery status, tire pressure)
Rstatus messages concerning the vehicle or its
individual components (e.g. wheel rpm/
speed, deceleration, lateral acceleration, indi- cation of whether seat belts are fastened)
Rmalfunctions and defects in important system
components (e.g. lights, brakes)
Rinformation about events leading to vehicle
damage
Rsystem responses in special driving situations
(e.g. air bag deployment, intervention of sta-
bility control systems)
Rambient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit function, these data are used by manufacturers
32Data stored in the vehicle
Introduction

to detect and rectify malfunctions and to opti-
mize vehicle functions. Most of these data are
volatile and processed only in the vehicle itself.
Only a small part 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 or third parties. Services can include
repair services, maintenance processes, war-
ranty cases and quality assurance measures.
The data is read out via the legally prescribed
diagnostics connection in the vehicle. The rele-
vant offices in the service network or third par-
ties collect, process and use the data. These
data document the vehicle's technical states,
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 s
elected 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-
tion, 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 th
e 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 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 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. The data exchange for this takes place
via a secure connection, e.g. with the manufac-turer's IT systems intended for the purpose. Col-
lecting, 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.

repaired. This will help to make sure the air bags
continue to perform their protective function for
the vehicle occupants in the event of a crash.
GWARNING
Emergency Tensioning Devices that have
deployed pyrotechnically are no longer opera-
tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
Tensioning Devices replaced immediately at a
qualified specialist workshop.
An electric motor is used by PRE-SAFE
®to trig-
ger the tightening of the seat belt in hazardous
situations. This procedure is reversible.
If Emergency Tensioning Devices are triggered
or air bags are deployed, you will hear a bang,
and some powder may also be released. The
6 restraint system warning lamp lights up.
Only in rare cases will the bang affect your hear-
ing. The powder that is released generally does
not constitute a health hazard, but it may cause short-term breathing difficulties in people with
asthma or other respiratory problems. Provided
it is safe to do so, you should leave the vehicle
immediately or open the window in order to pre-
vent breathing difficulties.
Air bags and pyrotechnic Emergency Tensioning
Devices (ETDs) contain perchlorate material,
which may require special handling and regard
for the environment. National guidelines must
be observed during disposal. In California, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
Method of operation
During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluation of this data, the
restraint system control unit triggers the Emer-
gency Tensioning Devices during a frontal or
rear collision. An Emergency Tensioning Device can only be
triggered, if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational. You can find further information
under "Restraint system warning lamp"
(
Ypage 45)
Rthe seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The Emergency Tensioning Devices in the rear
compartment are triggered independently of the
lock status of the seat belts.
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independ-
ently of each other in certain frontal collision
situations:
RFront air bags and driver's knee bag
RWindow curtain air bag, if the system deter-
mines that deployment can offer additional
protection to that provided by the seat belt
The front-passenger front air bag is activated or
deactivated depending on the person on the
front-passenger seat. The front-passenger front
air bag can only deploy in an accident if the
PASSENGER AIR BAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR
BAG indicator lamps (
Ypage 45).
Your vehicle has two-stage front air bags. In the
first deployment stage, the front air bag is filled
with propellant gas. The front air bag is fully
deployed with the maximum amount of propel-
lant gas if a second deployment threshold is
reached within a few milliseconds.
The activation threshold of the Emergency Ten-
sioning Devices and the air bags is determined
by evaluating the rate of vehicle decelera
tion or
acceleration which occurs at various points in
the vehicle. This process is pre-emptive in
nature. Deployment should take place in good
time at the start of the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristics of the vehicle
Rthe characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a deci-
sive role in the deployment of an air bag. Nor do

360° camera
General notes
The 360° camera is a system consisting of four
cameras.
The system processes images from the follow-
ing cameras:
RRear view camera
RFront camera
RTwo cameras in the exterior rear view mirrors
The cameras cover the immediate surroundings
of the vehicle. The 360° camera assists you, for
instance when parking or at exits with reduced
visibility.
You can show pictures from the 360° camera in
full-screen mode or in seven different split-
screen views on the multimedia system display.
A split-screen view also includes a top view of
the vehicle. This view is calculated from the data
supplied by the installed cameras (virtual cam-
era).
The six split-screen views are:
RTop view and picture from the rear view cam-
era (130° viewing angle)
RTop view and image from the front camera
(130° viewing angle without displaying the
maximum steering wheel angle)
RTop view and enlarged rear view
