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:
Rhow various systems in your vehicle are
operating
Rwhether or not the driver and passenger
seat belts are fastened
Rhow far (if at all) the driver is depressing
the accelerator and/or brake pedal and
Rhow 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 nontrivial
crash situation occurs. No data is recorded by
the EDR under normal driving conditions. No
personal data (e.g., name, gender, age, and
accident 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. EDR data may be
used in civil and criminal matters as a tool in
accident reconstruction, accident claims,
and vehicle safety.
To read data recorded by an EDR, special
equipment is required, and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer, other parties that
have the special equipment, such as law
enforcement, 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
("MBUSA") expressly disclaims any and all
liability arising from the extraction of this
information by unauthorized Mercedes-Benz
personnel.
MBUSA will not share EDR data with others
without the consent of the vehicle owners or,
if the vehicle is leased, without the consent
of the lessee. Exceptions to this representa- tion include responses to subpoenas by law
enforcement; by federal, state or local gov-
ernment; in connection with or arising out of
litigation involving MBUSA or its subsidi a-
ries and affiliates; or, as required by law. Warning: the EDR is a component of the
Restraint System Module. Tampering with,
altering, modifying or removing the EDR com-
ponent may result in a malfunction of the
Restraint System Module and other systems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-
empted. This means that in the event of such
conflict, the federal regulation governs. As
of February 2013, 13 states have enacted laws
related to EDRs.

Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of
vehicle occupants coming into contact with
parts of the vehicle's interior in the event of
an accident. Furthermore, the restraint sys-
tem may also reduce the forces exerted on the
vehicle occupants when an accident occurs.
The restraint system includes:
RSeat belt system
RAir bags The components of the restraint system work
in conjunction with each other. They can only
offer the intended level of protection if all
vehicle occupants:
Rare correctly wearing their seat belts.
(Ypage 32)
Radjust their seat properly (Ypage 61).
The driver is also responsible for ensuring
that the steering wheel has been correctly
positioned. Observe the information relat-
ing to the correct driver's seat position
(
Ypage 61).
Always ensure the air bag can inflate prop-
erly if deployed (
Ypage 34).
An air bag supplements a correctly fastened
seat belt. As an additional safety device, the
air bag increases the level of protection for
vehicle occupants in the event of an accident.
For example, if the protection already pro-
vided by a correctly fastened seat belt will
suffice, the air bags are not deployed. Fur-
thermore, only the air bags that would
increase the degree of protection afforded to
the vehicle occupants in the event of an acci-
dent are deployed. Seat belts and air bags
generally do not protect against objects pen-
etrating the vehicle from the outside.
Information on restraint system operation
can be found under "Triggering of Emergency
Tensioning Devices and air bags"
(
Ypage 40).
See “Children in the vehicle” for information on children traveling with you as well as
vehicle restraint systems (
Ypage 42).
Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail
in an accident or trigger unexpectedly, for
example. This poses an increased risk of
injury or even fatal injury.
Never modify parts of the restraint system. Never tamper with the wiring, the elec-
tronic components or their software.
If it is necessary to modify an air bag sys-
tem to accommodate a person with disabil-

Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and
at regular intervals while the engine is run-
ning. Therefore, malfunctions can be detec-
ted in good time.
The0075 restraint system warning lamp in
the instrument cluster lights up when the
ignition is switched on. It goes out no later
than a few seconds after the vehicle is star-
ted. The components of the restraint system
are in operational readiness.
A malfunction has occurred if the 0075
restraint system warning lamp:
Rdoes not light up after the ignition is
switched on
Rdoes not go out after a few seconds with the
engine running
Rlights up again while the engine is running
GWARNING
If restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with
a high rate of vehicle deceleration. This
can affect the Emergency Tensioning
Device or air bag, for example. This poses
an increased risk of injury or even fatal
injury.
Have the restraint system checked and
repaired in a qualified specialist work-
shop as soon as possible.
PASSENGER AIR BAG indicator lamps
PASSENGER AIR BAG OFF indicator lamp 0043and
PASSENGER AIR BAG ON indicator lamp 0044are
part of the Occupant Classification System
(OCS).
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up: the front-
passenger front air bag is enabled. If, in
the event of an accident, all deployment
criteria are met, the front-passenger front
air bag is deployed.
RPASSENGER AIR BAG OFF lights up: the
front-passenger front air bag is deactiva-
ted. It will then not be deployed in the
event of an accident.
Depending on the person in the front-
passenger seat, the front-passenger front air
bag must either be deactivated or enabled;
see the following points. You must make sure
of this both before and during a journey.
RChildren in a child restraint system:
whether the front-passenger front air bag
is enabled or deactivated depends on the
installed child restraint system, and the
age and size of the child. Therefore, be
sure to observe the notes on the "Occupant
Classification System (OCS)" (
Ypage 36)
and on "Children in the vehicle"
(
Ypage 42). There you will also find
instructions on rearward and forward-
facing child restraint systems on the
front-passenger seat.
RAll other persons: depending on the clas-
sification of the person in the front-
passenger seat, the front-passenger front
air bag is enabled or deactivated
(
Ypage 36). Be sure to observe the notes
on "Seat belts“ (Ypage 31) and "Air bags"

(Ypage 34). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of
vehicle occupants coming into contact with
parts of the vehicle interior or being ejected
from the vehicle. Furthermore, the seat belt
helps to keep the vehicle 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 by the seat belt
guide quickly or with a jerky movement, the
belt retractor 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 direc-
tion of the backrest.
The Emergency Tensioning Device does not
correct 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 accident.
!If the front-passenger seat is unoccu-
pied, do not insert the belt tongue into the
buckle of the front-passenger seat. This
may otherwise lead to the triggering of the
Emergency Tensioning Device in the event
of an accident, which will then need to be
replaced.
Important safety notes
The use of seat belts and child restraint sys-
tems 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 incorrectly fastened, it
cannot protect as intended. Furthermore,
an incorrectly fastened seat belt can cause
additional injury, for example, in an acci-
dent, during braking or when abruptly
changing direction. 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.
GWARNING
The seat belt does not offer the intended
level of protection if you have not moved
the backrest to an almost vertical position.
When braking 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 back-
rest is in an almost vertical position and
that the shoulder section of your seat belt
is routed across the center of your shoul-
der.
GWARNING
Persons under 5 ft (1.50 m)in height cannot
fasten the seat belt correctly without an
additional suitable restraint system. If
the seat belt is incorrectly fastened, it
cannot protect as intended. Furthermore,
an incorrectly fastened seat belt can cause
Occupant safety31

Z
additional injury, for example, in an acci-
dent, 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 twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for this smart vehicle. The
child restraint system must be appropriate
to the age, weight and size of the child
Ralways observe the instructions and safety
notes on "Children in the vehicle"
(
Ypage 42) in addition to the child
restraint system manufacturer's installa-
tion and operating instructions
Rbe sure to observe the instructions and
safety notes on the "Occupant classifica-
tion system (OCS)" (
Ypage 36)
GWARNING
The seat belts may not perform their inten- ded protective function if:
Rthey are damaged, modified, extremely
dirty, bleach or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency Tensioning Devices, belt
anchorages or inertia reels have been
modified
Seat belts may sustain non-visible damage
in an accident, e.g. due to glass splinters.
Modified or damaged seat belts may tear or
fail, e.g. in an accident. Modified Emer-
gency Tensioning Devices could acciden-
tally trigger or fail to deploy when neces-
sary. This poses an increased risk of injury
or even fatal injury.
Never modify the seat belts, Emergency
Tensioning Devices, belt anchorages or
inertia reels. Make sure that the seat belts
are undamaged, not worn out and clean. Fol-
lowing an accident, have the seat belts
checked immediately at a qualified spe-
cialist workshop.
Only use seat belts that have been approved
for your vehicle by smart.
Proper use of the seat belts
Pay attention to the safety notes about the
seat belt (Ypage 31).
All vehicle occupants must fasten the seat
belt correctly before setting off. Make sure
that all occupants are wearing their seat
belts correctly for the entire journey.
When fastening the seat belt, make sure that:
RThe seat belt tongue is inserted into the
belt buckle that belongs to the seat.
RThe seat belt is tightened across your body.
Avoid wearing bulky clothing, e.g. a winter coat.
RThe seat belt is not twisted.
Only then can the forces produced in the
event of an accident be evenly distributed
across the belt.
RThe shoulder section of the belt must always
be routed across the center of the shoulder.
The shoulder section of the belt should not come into contact with your neck and must
not be routed under the arm.
RThe lap belt must be taut and as low as pos-
sible over your lap.
The lap belt must always pass across your
hip joints and never across your stomach or
abdomen. Pregnant women must take par-
ticular care. If necessary, the lap belt canbe pushed down across the hip joints and
pulled tight using the shoulder section.
RThe seat belt is not routed over sharp,
pointed or fragile objects.
If these items are on or in your clothing,
e.g. eyeglasses, pens, keys, etc., stow theseitems in a more suitable location.
ROnly one person should use each seat belt at
any one time.
On no account should babies or children
travel sitting on the lap of another vehicle occupant. During an accident, they could be
crushed between the occupant and seat belt.
RObjects are not secured with a seat belt if
the seat belt is being used by one of the
vehicle’s occupants.
