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:
RSeat belt system
RAir 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:
Rhave fastened their seat belts correctly
(Ypage 41)
Rhave the seat and head restraint adjusted
properly (Ypage 84)
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 (
Ypage 84). You also have to make sure that an air bag can
inflate properly if deployed(
Ypage 43).
An air bag supplements acorrectly 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 spenetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 50).
See "Children in the vehicle" for information on
children traveling with you in the vehicle as well
as on child restraint systems (
Ypage 53).
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 electronic
components or their software.
If it is necessary to modify components of the
restraint system to accommodate aperson with
disabilities, contact an authorized Mercedes-
Benz Center for details. USA only: for further
information contact our Customer Assistance
Center at 1-800F OR-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.
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at
38Occupant safety
Safety

regular intervalswhile the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp on the
instrument cluster lights up when the ignitio nis
switched on. It goes out no later than afew sec-
onds after the vehicleiss tarted. The compo-
nents of the restraint system are in operational
readiness.
Am alfunction has occurred if the 6restraint
system warning lamp:
Rdoes not light up after the ignitio nisswitched
on
Rdoes not go out after afew seconds with the
engine running
Rlights up again while the engine is running
GWARNING
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 examplet he 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 aqualified specialist workshop as
soon as possible.
PASSENGER AI RBAG indicator lamp
PASSENGER AIR BAG ON indicator lamp :and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the Occupant Classification System
(OCS). The indicator lamp
sdisplay the status of the
front-passenge rfront air bag.
RPASSENGER AIR BAG ON lights up for 60 sec-
onds, subsequently both indicator lamp sare
off (PASSENGER AIR BAG ON and OFF): the
front-passenge rfront air bag is abl etodeploy
in the event of an accident.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deploye dinthe 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-passenge rfront air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during ajourney.
RChildren in achildr estraint system:
whethert he front-passenge rfront air bag is
enabled or deactivated depends on the instal- led child restraint system, and the age and
size of the child.T herefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypag e45) and on "Chil-
dren in the vehicle" (Ypag e53). There you
wil lalsof ind instructions on rearward and
forward-facing child restraint systems on the
front-passenge rseat.
RAll other persons: depending on the classi-
ficatio nofthe person in the front-passenger
seat, the front-passenge rfront air bag is ena-
bled or deactivated (
Ypag e45). Be sure to
observe the notes on "Seat
belts“ (
Ypag e39) and "Air bags"
(Ypag e43).T here you can als ofind infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicleo ccupants
in the event of an accident or the vehicler olling
over. This reduces the risk of vehicleo ccupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helpstok eep the vehicle
Occupant safety39

occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency TensioningDevices and seat belt
force limiters
If the seat belt is pulled quickly or sharply by the
seat belt guide, the inertia reel locks. The belt
strap cannot be extracted any further.
The Emergency TensioningD evice tightensthe
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 TensioningD evice does not cor-
rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, aseat 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 occupantsd uring an acci-
dent.
!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 the event of an accident the Emer-
gency TensioningD evice and the side impact
air bag, in addition to other systems, may be
triggered and have to be replaced.
Important safety notes
The use of seat belts and child restraint systems
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
occupantss hould correctly fasten their seat
belts before starting the journey.
GWARNING
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 occupantsh ave
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:
Rhave fastened their seat belts correctly
(Ypage 41)
Rhave the seat and head restraint adjusted
properly (Ypage 84)
GWARNING
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.
GWARNING
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, alwayss ecure persons under
5ft( 1.50 m) tall in suitable additional restraint
systems.
