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 includes the following com-
ponents:
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 47)
R have the seat and head restraint adjusted
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 correct
driver's seat position (Y page 97).
You also have to make sure that an air bag can
inflate properly if deployed (Y page 49).
An air bag supplements a correctly 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 protectionoffered 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 objects penetrating 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 56).
See "Children in the vehicle" for information on
children traveling with you in the vehicle as well
as on child restraint systems (Y page 59). 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 a person with
disabilities, contact an authorized Mercedes-
Benz Center for details. USA only: for further
information contact our Customer Assistance
Center at 1-800 FOR-MERCEDES
(1‑800‑367‑6372).
Mercedes-Benz recommends that you only use
driving aids which have been approved specifi-
cally for your vehicle by Mercedes-Benz. 44
Occupant safetySafety

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 running.
Therefore, malfunctions can be detected in
good time.
The 0075 restraint system warning lamp on the
instrument cluster lights up when the ignition is switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 0075restraint
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 the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This 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 a qualified specialist workshop as
soon as possible. PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp
0043and
PASSENGER AIR BAG OFF indicator lamp 0044are
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 for 60 sec-
onds, subsequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF): the
front-passenger front air bag is able to deploy in the event of an accident.
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.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front air bag. The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
Depending on the 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 a journey.
R Children in a child 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 51) and on "Chil-
dren in the vehicle" (Y page 59). 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 51). Be sure to
observe the notes on "Seat
belts“ (Y page 45) and "Air bags"
(Y page 49). 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 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 safety
45Safety Z

occupant in the best position 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 sec- ond row of seats as well as the seat belts in
the third row
R Seat belt force limiters for the front seat belts
and the outer seat belts in the second row of
seats as well as the seat belts in the third row
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 extrac-
ted 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 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 vehicle occu-
pants during an accident.
! 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 addition to other systems, the Emer-
gency Tensioning Device could also be trig-
gered in the event of an accident and would
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 occupants should 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 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:
R have fastened their seat belts correctly
(Y page 47)
R have the seat and head restraint adjusted
properly (Y page 97) 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 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. 46
Occupant safetySafety

For this reason, always secure persons under
5 ft (1.50 m)tall in suitable additional restraint
systems.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height istraveling in the
vehicle:
R always 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.
R always observe the instructions and safety
notes on "Children in the vehicle"
(Y page 59) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions
R always observe the instructions and safety
notes on the "Occupant Classification 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, bleached 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 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. Proper use of the seat belts Observe the safety notes on the seat belt
(Y
page 46).
Every vehicle occupant must observe the fol-
lowing notes to ensure a properly worn seat belt can provide full protection. 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:
R the seat belt buckle tongue is inserted only
into the belt buckle belonging to that seat
R the seat belt is pulled tight across your body
Avoid wearing bulky clothing, e.g. a winter
coat.
R the seat belt is not twisted
Only then can the forces which occur be dis-
tributed over the area of the belt.
R the 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. Where possible,
adjust the seat belt to the appropriate height.
R the 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.
R the 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.
R only one person is using a seat belt
Infants and children must never travel sitting
on the lap of a vehicle occupant. In the event
of an accident, they could be crushed
between the vehicle occupant and seat belt.
R objects are never secured with a seat belt if
the seat belt is also being used by one of the
vehicle's occupants
Also ensure that there are never objects
between a person and the seat, e.g. cushions.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe the
"Loading guidelines" for securing objects, lug-
gage or loads (Y page 295). Occupant safety
