Occupant safety
Introduction to the restraint system The restraint system can reduce 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
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 40) R
have adjusted their seat and head restraint
properly ( Y
page 82).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position ( Y
page 82). You also have to make sure that an air bag can
inflate properly if deploye d( Y
page 42).
An air bag supplements ac orrectly worn 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 exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags
are not deployed. When an accident occurs, only
the air bags that increase protection in that par-
ticular accident situation are deployed. How-
ever, seat belts and air bags generally do not
protect against object sp enetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" ( Y
page 48).
For information on children traveling with you in
the vehicle and on child restraint systems, see
"Children in the vehicle" ( Y
page 51).
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 components of the
restraint system to accommodate ap erson
with disabilities, contact an authorized
Mercedes-Benz Center for details. USA only:
for further information contact our Customer
Assistanc eC enter at 1-800-FOR-MERCedes
(1 ‑ 800 ‑ 36 7 ‑ 6372).

The u restraint system warning lamp in the
instrument cluster lights up when the ignition is
switched on. It goes out no later than af ew sec-
onds after the vehicle is started. The compo-
nent soft he restraint system are in operational
readiness.
Am alfunction has occurred if the u restraint
system warning lamp: R
does not light up after the ignition is switched
on R

G WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident .T his can affect
for example the Emergency Tensioning
Device or the air bag. This poses an increased
risk of injury or even fatal injury.
Have the restraint system checked and
repaired in aq ualified 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 Classification 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 ,a ll 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 deactivated. It will
then not be deployed in the event of an acci-
dent.
Dependin gont he person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during aj ourney.R
Children in ac hild restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" ( Y
page 44) and on "Chil-
dren in the vehicle" ( Y
page 51). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat. R
All other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated ( Y
page 44). Be sure to
observe the notes on "Seat
belts“ ( Y
page 38) and "Air bags"
( Y
page 42). There you can also find infor-
mation on the correc ts eat position.
Seat belts
Introduction Seat belts are the most effective means of
restrictin gt he movemen tofv ehicle occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.
The seat belt system comprises: R
Seat belts R
Emergency Tensionin gD evices and seat belt
force limiters
If the seat belt is pulled by the belt loop quickly
or with aj erk ym ovement, the belt retractor
locks. The belt strap cannot be extracted any
further.38
Occupant safety
Safety

The Emergency Tensionin gD evice tighten st he
seat belt in an accident ,p ulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensionin gD evice does not cor-
rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, as eat 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 occupant sd uring an acci-
dent.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of
the front-passenger seat. This may otherwise
lead to the triggerin goft he Emergency Ten-
sioning 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 systems
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
occupant ss hould correctly fasten their seat
belts before starting the journey.
G WARNING
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 occupant sh ave
their seat belts fastened correctly and are sit-
ting properly.
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 ,y ou 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 less than 5ft( 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, alway ss ecure persons under
5ft( 1.50 m) tall in suitable additional restraint
systems.
If ac hild younger than twelve years old and
under 5ft( 1.50 m) in height is traveling in the
vehicle: R
alway ss ecure the child in ac hild 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 R
alway so bserve the instructions and safety
notes on "Children in the vehicle"
( Y
page 51) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions R
