In situations like this, the body, the under-
carriage, chassis parts, wheels or tires
could be damaged without the damage
being visible. Components damaged in this way can unexpectedly fail or, in the case of
an accident, no longer withstand the strain
they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system, they can catch fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If on con-
tinuing your journey you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
consult a qualified specialist workshop. Declarations of conformity

Introduction

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
rescue card for your vehicle. The current res- cue card contains the most important infor-
mation about your vehicle in a compact form, e.g. the routing of the electric cables.
You can find more information under https://
portal.aftersales.i.daimler.com/public/

Data recording
This vehicle is capable of recording diagnostic information relating to vehicle operation, mal-
functions, and user settings. This may include information about the performance or status
of various systems, including but not limited
to, engine, throttle, steering or brake sys-
tems, that is stored and can be read out with
suitable devices, particularly when the vehi-
cle is serviced. The data obtained is used to
properly diagnose and service your vehicle or to further optimize and develop vehicle func-
tions. COMAND/mbrace (Canada: TELEAID)
If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle’s
operation, the use of the vehicle in certain
situations, and the location of the vehicle may be compiled through COMAND or the mbrace
system.
For additional information please refer to the COMAND User Manual and/or the mbrace
Terms and Conditions. Event data recorders
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record data that will assist in under-
standing how a vehicle’s systems performed
in certain crash or near crash-like situations,
such as during air bag deployment or when
hitting a road obstacle. The EDR is designed
to record data related to vehicle dynamics
and safety systems for a short period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
R how various systems in your vehicle are
operating
R whether or not the driver and passenger
seat belts are fastened
R how far (if at all) the driver is depressing the
accelerator and/or brake pedal and
R how fast the vehicle is traveling
This data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur. NOTE: EDR data is
recorded by your vehicle only if a non-trivial
crash situation occurs; no data is recorded by the EDR under normal driving conditions andno personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, can
combine the EDR data with the type of per-
sonal identification data routinely acquired
during a crash investigation.
To read data recorded by an EDR, special
equipment is required, and access to the vehi-
cle or the EDR is needed. In addition to the
vehicle manufacturer, other parties that have
the special equipment, such as law enforce-
ment, can read the information by accessing
the vehicle or the EDR.
EDR data may be used in civil and criminal
matters as a tool in accident reconstruction,
accident claims, and vehicle safety. Since the Crash Data Retrieval CDR tool that is used to extract data from the EDR is commercially
available, Mercedes-Benz USA, LLC 26

Restraint system: introduction
The restraint system reduces the risk of vehi-
cle occupants coming into contact with parts of the vehicle's interior in the event of an
accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system comprises:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing systems
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:
R have fastened their seat belts correctly
(Y page 44)
R have adjusted their seat and head restraint
properly (Y page 97).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (Y page 96).
You also have to make sure that an air bag can inflate properly if deployed (Y page 46).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air
bag increases the level of protection for vehi-
cle occupants in the event of an accident. For example, if, in the event of an accident, the
protection offered by the seat belt is suffi-
cient, the air bags are not deployed. When an
accident occurs, only the air bags that
increase protection in that particular accident
situation are deployed. However, seat belts
and air bags generally do not protect against objects penetrating the vehicle from the out-
side.
Information on restraint system operation
can be found under "Triggering of the Emer-
gency Tensioning Devices and air bags"
(Y page 54). 40
Occupant safetySafety

tion. This poses an increased risk of injury or
even fatal injury.
Make sure that all vehicle occupants are
seated properly with a correctly fastened seat belt. G
WARNING
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. G
WARNING
Persons under 5 ft (1.50 m) in heightcannot
fasten the seat belt correctly without an addi- tional suitable restraint system. If the seat
belt is incorrectly fastened, it cannot protect
as intended. Furthermore, an incorrectly fas-
tened seat belt can cause additional injury, for
example, in an accident, during braking or an
abrupt change of direction. This poses an
increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) in height in suitable restraint
systems.
If a child younger than 12 years and under 5 ft
(1.50 m) in height is traveling in the vehicle:
R always secure the child in a child restraint
system suitable for this Mercedes-Benz
vehicle. The child restraint system must be appropriate to the age, weight and size of
the child
R always observe the instructions and safety
notes in the "Children in the vehicle" sec-
tion of this Operator's Manual
(Y page 56) in addition to the child restraint system manufacturer's installa-
tion instructions
R be sure to observe the instructions and
safety notes on the "Occupant classifica-
tion system (OCS)" (Y page 49) G
WARNING
The seat belts may not perform their intended protective function if:
R they are damaged, modified, extremely
dirty, bleach or dyed
R the seat belt buckle is damaged or
extremely dirty
R the Emergency Tensioning Devices, belt
anchorages or inertia reels have been modi-
fied
Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts may tear or fail,
e.g. in an accident. Modified Emergency Ten-
sioning 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 or 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. Any such
modifications could invalidate the vehicle's
general operating permit.
Vehicles with a sports seat or AMG Per-
formance seat: these seats are 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 can-
not provide the best level of protection. G
WARNING
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 Occupant safety
