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. 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 46) R
have adjusted their seat and head restraint
properly ( Y
page 101).
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 100).
You also have to make sure that an air bag can
inflate properly if deployed ( Y
page 48).
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 56).42

Important safety notes
G WARNING
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 electronic
components or their software.
If it is necessary to modify an air bag system to
accommodate a person with disabilities, con-
tact an authorized Mercedes-Benz Center for
details. USA only: for further information con-
tact our Customer Assistance Center at
1-800-FOR-MERCedes (1 ‑ 800 ‑ 367 ‑ 6372).
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.
The u restraint system warning lamp in
the instrument cluster lights up when the igni-
tion is switched on. It goes out no later than a
few seconds after the vehicle is started. The
components of the restraint system are in
operational readiness.
A malfunction has occurred if the u
restraint system warning lamp: R
does not light up after the ignition is
switched on R
does not go out after a few seconds with
the engine running R
lights up again while the engine is running G WARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer-
gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp C
and PASSENGER AIR BAG OFF indicator
lamp D are part of the Occupant Classifica-
tion System (OCS).
The indicator lamps display the status of the
front-passenger front air bag. R
PASSENGER 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. R
PASSENGER 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.Occupant safety 43
Safety Z

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. R
Children 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 Clas-
sification System (OCS)" ( Y
page 51) and
on "Children in the vehicle" ( Y
page 58).
There you will also find instructions on rear-
ward and forward-facing child restraint sys-
tems on the front-passenger seat. R
All 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
( Y
page 51). Be sure to observe the notes
on "Seat belts“ ( Y
page 44) and "Air bags"
( Y
page 48). 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 vehi-
cle 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 posi-
tion in relation to the air bag.
The seat belt system comprises: R
Seat belts R
Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear R
Seat belt force limiters for the front seat
belts and the outer seat belts in the rear If the seat belt is pulled out of the belt outlet
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 direction
of the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the rout-
ing of an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps
to reduce the force exerted by the seat belt on
th e vehicle occupant.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This can reduce the force exerted on the vehi-
cle occupants during an accident.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle
of the front-passenger seat. This may oth-
erwise lead to the triggering of the Emer-
gency 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: R
all 50 states R
the U.S. territories R
the District of Columbia R
all Canadian provinces
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.
G WARNING
If the seat belt is incorrectly fastened, it can-
not protect as intended. Furthermore, an
incorrectly fastened seat belt can cause addi-
tional injury, for example, in an accident, dur-
ing braking or when abruptly changing direc-44

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 height cannot
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 restrain t
systems.
If a child younger than twelve years old 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 58) 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 51)
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.
Sports seat or AMG Performance seat: this
seat is designed for the standard three-point
seat belt. If you install another mu lti-point
s eat belt, e.g. sport or racing seat belts, the
restraint system cannot 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
accident. This poses an increased risk of
injury or even fatal injury.Occupant safety 45

passenger seat belts are not fastened, a
warning tone sounds. A warning tone also
sounds with increasing intensity for
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again.
i For more information on the v seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" ( Y
page 258).
Air bags
Introduction The installation point of an air bag can be rec-
ognized by the AIR BAG symbol.
An air bag complements the correctly fas-
tened seat belt. It is no substitute for the seat
belt. The air bag provides additional protec-
tion in applicable accident situations.
Not all air bags are deployed in an accident.
The different air bag systems function inde-
pendently from one another ( Y
page 56).
However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
G WARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury. To avoid hazardous situations, always make
sure that all of the vehicle's occupants: R
have fastened their seat belts correctly,
including pregnant women R
are sitting correctly and maintain the great-
est possible distance to the air bags R
follow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants. R
Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level. R
Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely. R
Only hold the steering wheel on the out-
side. This allows the air bag to be fully
deployed. R
Always lean against the backrest while driv-
ing. Do not lean forwards or lean against
the door or side window. You may other-
wise be in the deployment area of the air
bags. R
Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth-
erwise be in the deployment area of the air
bag. R
For this reason, always secure persons less
than 5 ft (1.50 m) tall in suitable restraint
systems. Up to this height, the seat belt
cannot be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes: R
Always secure children under twelve years
of age and less than 5 ft (1.50 m) tall in
suitable child restraint systems. R
Child restraint systems should be installed
on the rear seats.48
