Introduction

The following text is published as required of
manufacturers under Title 49, Code of U.S. Fed-
eral Regulations, Part 575 pursuant to the
"National Traffic and Motor Vehicle Safety Act of
1966".
If you believe that your vehicle has a defect
which could cause a crash or could cause injury
or death, you should immediately inform the

open an investigation, and if it finds that a safety
defect exists in a group of vehicles, it may order
a recall and remedy campaign. However, NHTSA
cannot become involved in individual problems
between you, your dealer, or Mercedes-Benz
USA, LLC.
To contact NHTSA, you may call the Vehicle
Safety Hotline toll-free at 1-888-327-4236
(TTY: 1-800-424-9153); go tohttp://
www.safercar.gov; or write to: Administrator,
NHTSA, 400 Seventh Street, SW., Washington,
DC 20590.

Limited Warranty
!
Observe the notes in this Operator's Manual
regarding the correct operation of your vehi-
cle and possible damage to the vehicle. Dam-
age to the vehicle which is caused by violation
of these notes is not covered by the
Mercedes-Benz implied warranty or the new
or used-vehicle warranty.
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 under
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
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,
Data stored in the vehicle29

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.

occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices and seat belt
force limiters
If the seat belt is pulled quickly or sharply by the
seat belt guide, the inertia reel locks. The belt
strap cannot be extracted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensioning Device does not cor- rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters are synchronized
with the front air bags which absorb part of the
deceleration force. This can reduce the force
exerted on the vehicle occupants during an acci-
dent.
!If the front-passenger seat is not occupied,
do not engage the seat belt tongue in the
buckle on the front-passenger seat. Other-
wise, in the event of an accident the Emer-
gency Tensioning Device and the side impact
air bag, in addition to other systems, may be
triggered and have to be replaced.
Important safety notes
The use of seat belts and child restraint systems
is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
Even where this is not required by law, all vehicle
occupants should correctly fasten their seat
belts before starting the journey.
GWARNING
If the seat belt is not worn correctly, it cannot
perform its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury or even fatal injury.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sit-
ting properly.
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 43)
Rhave the seat adjusted properly
(Ypage 84)
Depending on the vehicle's equipment, the
head restraints must also be adjusted prop-
erly.
GWARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
GWARNING
Persons less than 5 ft (1.50 m) tall cannot
wear the seat belt correctly without an addi-
tional and suitable restraint system. If the
seat belt is not worn correctly, it cannot per-
form its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) tall in suitable additional restraint
systems.
42Occupant safety
Safety

If a child younger than twelve years old and
under 5 ft (1.50m)in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for this Mercedes-Benz vehi-
cle. The child restraint system must be appro-
priate to the age, weight and size of the child.
Ralways observe the instructions and safety
notes on "Children in the vehicle"
(
Ypage 55) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions
Ralways observe the instructions and safety
notes on the "Occupant classification system
(OCS)" (
Ypage 48)
GWARNING
The seat belts may not perform their intended protective function if:
Rthey are damaged, modified, extremely
dirty, bleached or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency Tensioning Devices, belt
anchorages or inertia reels have been modi-
fied.
Seat belts may be damaged in an accident,
although the damage may not be visible, e.g.
due to splinters of glass. Modified or damaged
seat belts may tear or fail, e.g. in an accident.
Modified Emergency Tensioning Devices
could accidentally trigger or fail to deploy
when necessary. This poses an increased risk
of injury or even fatal injury.
Never modify the seat belts, Emergency Ten-
sioning Devices, belt anchorages and inertia
reels. Make sure that the seat belts are
undamaged, not worn out and clean. Follow-
ing an accident, have the seat belts checked
immediately at a qualified specialist work-
shop.
Only use seat belts that have been approved for
your vehicle by Mercedes-Benz.
AMG Performance seat: this seat is designed
for the standard three-point seat belt. If you
install another multi-point seat belt, e.g. sport or
racing seat belts, the restraint system cannot
provide the best level of protection.
GWARNING
If you feed seat belts through the opening in
the seat backrest, the seat backrest may be
damaged or may even break in the event of an accident. This poses an increased risk of
injury or even fatal injury.
Only use the standard three-point seat belt.
Never modify the seat belt system.
Proper use of the seat belts
Observe the safety notes on the seat belt
(Ypage 42).
All vehicle occupants must be wearing the seat
belt correctly before beginning the journey. Also
make sure that all vehicle occupants are always
wearing the seat belt correctly while the vehicle
is in motion.
When fastening the seat belt, always make sure
that:
Rthe seat belt buckle tongue is inserted only
into the belt buckle belonging to that seat
Rthe seat belt is pulled tight across your body
Avoid wearing bulky clothing, e.g. a winter
coat.
Rthe seat belt is not twisted
Only then can the forces which occur be dis-
tributed over the area of the belt.
Rthe shoulder section of the belt is routed
across the center of your shoulder
The shoulder section of the seat belt should
not touch your neck or be routed under your
arm or behind your back.
Rthe lap belt is taut and passes across your lap as low down as possible
The lap belt must always be routed across
your hip joints and not across your abdomen.
This applies particularly to pregnant women.
If necessary, push the lap belt down to your
hip joint and pull it tight using the shoulder
section of the belt.
Rthe seat belt is not routed across sharp, poin-
ted or fragile objects
If you have such items located on or in your
clothing, e.g. pens, keys or eyeglasses, store
these in a suitable place.
Ronly one person is using a seat belt
Infants and children must never travel sitting
on the lap of a vehicle occupant. In the event
