on the functional features in question in the
respective operating instructions. These are also
available online and, depending on the equipment, digitally in the vehicle.
Personal data
Each vehicle is marked with a unique vehicle iden-
ti"Ncation number. Depending on the country, this
vehicle identi"Ncation number can be used by, for
example, government authorities to determine the
identity of the owner. There are other possibilities
for using data collected from the vehicle to iden- tify the owner or driver (e.g. the license plate
number).
The data generated or processed by control units
may therefore be personal or, under certain con-
ditions, become personal. Depending on what vehicle data is available, it may be possible to
make inferences about e.g. your driving behavior,
location, route or use patterns.
Legal requirements for the disclosure of data
If legal regulations exist, manufacturers are gener-
ally obligated to release data stored by the manu- facturer to the necessary extent in individualcases at the request of state authorities. This maybe the case during the investigation of a criminalo"Mense, for example.
Within the framework of applicable law, state authorities are also authorized to read out data
from vehicles themselves in speci"Nc cases. In the
event of an accident, for example, information can
be read from the air bag control unit that can help to establish what happened.
Operating data in the vehicle
Control units process data to operate the vehicle.
This includes the following data:
= Vehicle status information such as the speed,
longitudinal acceleration, lateral acceleration,
number of wheel revolutions or the fastened seat belts display
= Ambient conditions such as temperature, rain
sensor or distance sensor
As a rule, this data is volatile, is not stored beyond the operating time and is processed only in thevehicle itself. Control units (e.g. the vehicle key)
o"sen contain data memories. These are used to
temporarily or permanently document information
on the vehicle condition, component stress, main-tenance requirements or technical events and
malfunctions.
Depending on the technical equipment, the fol- lowing data is stored:
= Operating status of system components (e.g.
"Nll levels, tire pressure, battery status)
= Malfunctions or faults in important system
components (e.g. lights, brakes)
= System reactions in special driving situations
(e.g. air bag deployment, the intervention of
stability control systems)
= information on events leading to vehicle dam-
age
In special cases, it may be necessary to store data that would otherwise only be volatile. This may be the case if the vehicle has detected a mal-function, for example.
If you use services such as repair services or
maintenance work, stored operational data can be
read out and used together with the vehicle identi-
"Ncation number, where necessary. It can be read
out by service network employees (e.g. work- shops and manufacturers) or third parties (e.g.General notes39

breakdown services). The same applies to war-ranty cases and quality assurance measures.
The data is usually read out via the diagnostics
connection in the vehicle, which is required by
law. The operating data that is read out docu-
ments technical conditions of the vehicle or indi-
vidual components and helps to diagnose mal-
functions, meet warranty obligations and improve
quality. This data, in particular information on
component stress, technical events, operating
errors and other malfunctions, is transmitted to the manufacturer for this purpose together with
the vehicle identi"Ncation number if necessary. In
addition, the manufacturer is subject to product liability. For this reason, the manufacturer also
uses operational data from the vehicle for e.g.
recalls. This data can also be used to check cus-
tomer claims for warranty and guarantee.
Malfunction memories in the vehicle can be reset
during repair or service work or, at your request,
by a service company.Comfort and infotainment functions
You can save comfort settings and customizations
in the vehicle and change or reset them at any time.
Depending on the vehicle equipment, this
includes the following settings:
= Seat positions and steering wheel positions
= Suspension tuning and climate control set-
tings
= Personalized settings (e.g. interior lighting)
You can incorporate data into the vehicle\bs info-
tainment functions yourself as part of the selec- ted equipment.
Depending on the vehicle equipment, this
includes the following data:
= Multimedia data (e.g. music, "Nlms or photos
for playback in an integrated multimedia sys- tem)
= Address book data for use in conjunction with
an integrated hands-free system or integrated
navigation system
= Navigation destinations that have been
entered= Data about using Internet services
This data for comfort and infotainment functions
can be saved locally in the vehicle or is stored on
a device that you have connected to the vehicle
(e.g. smartphone, USB "Oash drive or MP3 player).
If you have entered data yourself, you can delete
it at any time.
The transfer of this data out of the vehicle takes place exclusively at your request. This applies inparticular when you are using online services
according to the settings you have selected.
Smartphone integration (e.g. Android Auto or Apple CarPlay n
)
If your vehicle is equipped appropriately, you can
connect your smartphone or another mobile end
device to the vehicle. You can then control them using the controls integrated in the vehicle. Thesmartphone\bs picture and sound can be output
via the multimedia system. Speci"Nc items of infor-
mation are also sent to your smartphone.
Depending on the type of integration, this
includes position data, day/night mode and other
general vehicle statuses. Please refer to the vehi-40General notes

cle Operator\bs Manual / infotainment systemoperating instructions for further information.
This integration allows the use of selected smart-
phone apps (e.g. navigation apps, music player apps). No additional interaction !

information for the manufacturer and its data pro-
tection o"Pcers.
At a workshop, for example, with the support of a specialist and possibly for a fee, you can have data read out which is stored only locally in the
vehicle.
MBUX multimedia system/Mercedes me connect
If the vehicle is equipped with the MBUX multime-
dia system or Mercedes me connect, additional
data about the vehicle\bs operation, the use of the
vehicle in certain situations, and the location of
the vehicle may be compiled by the MBUX multi- media system or Mercedes me connect.
For additional information, please refer to the
"MBUX multimedia system" section and/or the Mercedes me connect Terms and Conditions.
Event data recorder
USA only:
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an air bag deployment or hitting a road obstacle, data that will assist in understand-
ing how a vehicle!

its subsidiaries and a"Pliates; or, as required by
law.
Warning: The EDR is a component of the Restraint System Module. Tampering with, altering, modify-
ing or removing the EDR component may result in
a malfunction of the Restraint System Module and other systems.
State laws or regulations regarding EDRs that con"Oict with federal regulation are pre=-empted.
This means that in the event of such con"Oict, the
federal regulation governs. As of Dec 2016, 17
states have enacted laws relating to EDRs.

Brief overview of the most important points
Basic information
Make sure that the following prerequisites in par-
ticular have been met so that the components of the restraint system are able to provide the inten-ded level of protection:
= Sit correctly (  page 45).
= Fasten the seat belt correctly (  page 46).
- Function of the seat belt warning lamp

Note that negligence when adjusting your sittingposture and fastening the seat belt may have seri-
ous consequences. Be diligent and make sure that all vehicle occupants are sitting correctly and
have fastened their seat belts properly before
starting every journey.
Information on the correct seat position
The seat position must be correct in order for the
components of the restraint system to provide the intended level of protection.
The seat position in"Ouences both the protection
provided by the seat belt and the additional pro- tection provided by the air bag.
The correct seat position with an almost upright
posture and a correctly fastened seat belt also
reduce the risk posed by the air bag when it is
deployed.
When choosing the seat, take note of the available space. When you are sitting with the right posture
in a nearly upright position, your head should not
touch the roof.
&WARNING Risk of injury or death due to
an incorrect seat position
If you deviate from the correct seat position,
the air bag cannot provide its intended protec-
tive function.
Each vehicle occupant must make sure of the
following.
Put the seat in the correct position.Fasten seat belts correctly. Pregnant
women must take particular care to
ensure that the lap belt never lies across
the abdomen.Observe the following information.
In order for the restraint system to provide the intended level of protection, observe the following information:
= Before starting your journey, adjust your seat
correctly (  page 101).
When doing so, make sure you are able to fas-
ten your seat belt correctly. The shoulder belt
strap must be routed forward from the seat belt outlet over the center of your shoulder.
= Keep your distance from the air bags, espe-
cially the front air bags. Set the driver\bs seatand front passenger seat as far back as possi-
ble while making sure the seat belt is fastened
correctly.
= If persons are sitting on the rear seats, vehicle
occupants should maintain a su"Pcient dis-
tance to the parts of the vehicle interior in front of them.
= Make sure there are no people, animals or
objects between the vehicle occupants and an air bag.
= If you are the driver, observe the following
information on the correct position of the driv-
er\bs seat (  page 101).
Hold the steering wheel only by the steering wheel rim. This allows the driver\bs air bag to
fully deploy.
= Assume a nearly upright position, with your
buttocks as far back as possible in the gap between the seat cushion and seat backrest.
This ensures that your back lies as "Oat and
"Nrmly as possible against the seat backrest.Occupant safety !

=While driving, do not lean forward and do not
lean against the door or side window. You may otherwise be in the deployment area of the air
bags.
= Sit with your feet resting on the "Ooor, if possi-
ble. Your thighs are slightly supported by the seat cushion
Do not put your feet up on the cockpit, for
example. Your feet may otherwise be in the
deployment area of the air bag.
= Fasten the seat belt correctly.
Notes on wearing the seat belt correctly
Always fasten your seat belt correctly before
starting a journey. A seat belt can provide the
best level of protection only if it is worn correctly.
&WARNING Risk of injury or death due to
incorrectly fastened seat belt
If the seat belt is not worn correctly, it cannot
perform its intended protective function.
In addition, an incorrectly fastened seat belt
can also cause injuries, for example, in the event of an accident or when braking or
changing direction suddenly.Always ensure that all vehicle occupants
have their seat belts fastened correctly
and are sitting properly.&WARNING Risk of injury or death when
additional restraint systems are not used
for persons with a smaller stature
Persons under 5 "s (1.50 m ) tall cannot wear
the seat belt correctly without a suitable addi-
tional restraint system.
Always secure persons under 5 "s
(1.50 m) tall in a suitable restraint sys-
tem.
Each vehicle occupant must observe the following
notes in particular:
= The seat belt must not be twisted:
=The shoulder belt strap must be routed
forward from the seat belt outlet over the cen- ter of your shoulder.
= The shoulder belt strap should neither touch
your neck nor be routed under your arm or
behind your back.
= The lap belt must be routed as low down
across the hips as possible.
In addition, push the lap belt down as far as
possible across your hips and pull tight with the shoulder belt strap. Never route the lap
belt across your abdomen.
Pregnant women must also take particular
care with this.
= The shoulder belt strap and lap belt must "Nt
snugly against the body a"ser being tightened.
= Avoid wearing bulky clothing, e.g. a winter
coat.
= Never route the seat belt across sharp, poin-
ted, abrasive or fragile objects.
= Only one person should use each seat belt at
any one time.46Occupant safety !

=Never secure objects with a seat belt if the
seat belt is also being used by one of the vehi-
cle\bs occupants.
Also ensure that no objects, e.g. a cushion,
are ever placed between a person and the seat.
Fastening and adjusting seat belts
If the seat belt is pulled quickly or sharply, the
seat belt retractor locks. The seat belt strap can-
not be pulled out any further.
Always engage seat belt tongue 1 of the seat
belt into seat belt buckle 2 of the corre-
sponding seat.To adjust the seat belt height: press button 3
on the seat belt outlet and slide the seat belt outlet to the desired position.To engage the seat belt outlet: release button
3 and ensure that the seat belt outlet
engages.*NOTE Deployment of components of the
restraint system when the front passenger
seat is unoccupied and a seat belt is
buckled
When the front passenger seat is unoccupied
and the seat belt tongue of the seat belt is
engaged in the seat belt buckle, components
of the restraint system may deploy unnecessa-
rily on the front passenger side, e.g. the Emer-
gency Tensioning Device.
Only buckle the seat belts as intended.\bObserve the information on child seat safety
feature of the seat belt (  page 69).
Function of the restraint system warning lamp
When the vehicle is switched on, a self-test is per-
formed, during which the restraint system warning lamp u lights up. It goes out no later than a
few seconds a"ser the vehicle is started. The com-
ponents of the restraint system are then func-
tional.
Occupant safety !

A malfunction has occurred in the restraint sys-tem if:
= the restraint system warning lamp u does
not light up when the vehicle is switched on
= the restraint system warning lamp u lights
up continuously or repeatedly during a journey
If components of the restraint system have been
deployed, the restraint system warning lamp u
lights up continuously.&WARNING Risk of injury due to malfunc-
tions in the restraint system
Components in the restraint system may be activated unintentionally or not deploy as plan-
ned in an accident.
Have the restraint system checked and
repaired immediately at a quali"Ned spe-
cialist workshop.
Plug-in hybrid vehicles: if the restraint system is
malfunctioning, the automatic high voltage emer-
gency shuto"M may not function.
&DANGER Risk of fatal injuries due to mal-
functions of the automatic high-voltage
emergency shuto"M
In the event of an accident, the high-voltage
on-board electrical system may not be deacti-
vated as intended.
You may be electrocuted if you touch the dam-
aged component parts of the high-voltage on-
board electrical system.
Have the automatic high-voltage emer-
gency shuto"M checked and repaired
immediately at a quali"Ned specialist
workshop.A"ser an accident, switch o"M the vehicle
immediately.
Mercedes-Benz recommends that you have the
vehicle towed to a quali"Ned specialist workshop.
