Occupant safety
Restraint system introduction
The restraint system can reduce the risk of vehi- cle occupants comingi ntoc ontact with parts of
the vehicle' sinterior in the eventofana ccident.
Furthermore, the restraint system may also
reduce the forces exerted on the vehicle occu-
pant swhen an acciden toccurs.
The restraint system includes:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securings ystem
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 45)
Radjust their seat and head restraint properly
(Ypage 83).
The driver is also responsible for ensurin gthat
the steering wheel has been correctly posi-
tioned. Observet he information relatin gtothe
correct driver'ss eat position (
Ypage 83).
Always ensure the air bag can inflat eproperly if
deployed (
Ypage 48).
An air bag supplement sacorrectly fastened
seat belt. As an additional safetyd evice, the air
bag increases the level of protection for vehicle
occupants in the eventofana ccident. For exam-
ple, if the protection already provided by acor-
rectly fastened seat belt will suffice, the air bags
are not deployed. Furthermore, only the air bags
that would increase the degree of protection
afforded to the vehicle occupants in the evento fan acciden
tare deployed. Seat belts and air
bags generally do not protect against objects
penetratin gthe vehicle from the outside.
Information on restraint system operatio ncan
be found under "TriggeringofE mergencyTen-
sionin gDevices and air bags" (
Ypage 54).
See “Children in the vehicle” for information on children traveling with you as well as vehicle
restraint system s(

Seat belts
Introduction
Ac orrectly fastened seat beltist he most effec-
tive means of restraining the movement of vehi- cle occupants 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 vehiclei nterior or being thrown from
the vehicle. Furthermore ,the seat belth elpsto
keep the vehicleo ccupants in the best position
in relation to the air bag.
The seat belts ystem consists of:
RSeat belts

When the front-passenger seat is occupied,
alwaysp ay attention to the PASSENGER AIR
BAG OFF indicator lamp. Make sure the correct
status is displayed for the front-passenger air
bag before and during the journey.
If the PASSENGER AIR BAG OFF indicator
lamp:
Rlights up ,the front-passenger air bag is deac-
tivated. It will not be deployed in the event of
an accident.
Rdoes not light up,t he front-passenger air

GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger fronta ir bag is
disabled. It will not be deployed in the event of
an accidenta nd cannot perform its intended
protective function .Aperson in the front-
passenger seat could then ,for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injur yore ven fatal injury.
When the front-passenger seat is occupied,
alwayse nsure that:
Rthe classification of the person in the front-
passenger seat is correct and the front-
passenger fronta ir bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated correctly.

This poses an increased risk of injury or evenfatal injury.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the vehicle belt sash guide. If nec-
essary, adjust the vehicle belt sash guide and
the front-passenger seat accordingly. Always
observe the child restraint system manufac-
turer's installation instructions.
If OCS determines that:
Rthe front-passenger seat is unoccupied, the
PASSENGER AIR BAG OFF indicator lamp
lights up after the system self-test and
remains lit. This indicates that the front-
passenger air bag has been deactivated.
Rthe front-passenger seat is occupied by a
child of up to 12 months old in astandard
child restraint system, the PASSENGER AIR
BAG OFF indicator lamp lights up after the
system self-test and remains lit. This indi-
cates that the front-passenger air bag has
been deactivated.
But even in the case of a12-month-old child in
as tandard child restraint system, the
PASSENGER AIR BAG OFF indicator lamp can
go out after the system self-test. This indi-
cates that the front-passenger air bag has
been activated. The classification depends,
among other things, on the child restraint sys-
tem and the size and weight of the child. In
this case, install the child restraint system on
as uitable rear seat.
Rthe front-passenger seat is occupied by aper-
son of smaller stature (e.g. ateenager or
small adult), the PASSENGER AIR BAG OFF
indicator lamp lights up and remains lit after
the system self-test depending on the result
of the classification or, alternatively, goes out.
-If the PASSENGER AIR BAG OFF indicator
lamp is not lit, move the front-passenger
seat as far back as possible. Alternatively, a person of smaller stature can sit on
arear
seat.
-If the PASSENGER AIR BAG OFF indicator
lamp is lit, aperson of smaller stature
should not use the front-passenger seat.
Rthe front-passenger seat is occupied by an
adult or aperson of astature corresponding
t o
that of an adult, the PASSENGER AIR BAG
OFF indicator lamp goes out after the system
self-test. This indicates that the front-
passenger air bag has been activated.
If children are also traveling in the vehicle,
please observe the instructions about “Children
in the vehicle” (
Ypage 56).
If OCS is malfunctioning, the red 6restraint
system warning lamp in the instrument cluster
and the PASSENGER AIR BAG OFF indicator
lamp light up simultaneously. This signals that
the front-passenger air bag has been deactiva-
ted and will not be deployed in the event of an
accident .Have the system checked by aquali-
fied technician as soon as possible. Consult a
Mercedes-Benz Commercial Van Center. The
front-passenger seat should only be repaired at aM ercedes-Benz Commercial Van Center.
If the front-passenger seat, the seat cover or the
upholstery is damaged, have the necessary
repair work carried out at aMercedes-Benz
Commercial Van Center.
For safety reasons, Mercedes-Benz recom-
mends that you only use seating accessories
that have been specially approved for
Mercedes-Benz vehicles.
If the driver's air bag deploys, this does not
mean the front-passenger air bag must also
deploy. The Occupant Classification System
(OCS) classifies occupantsont he front-
passenger seat. Dependin gonthe outcome, the
front-passenger air bag is either activated or
deactivated.
System self-test
GDANGER
If the PASSENGER AIR BAG OFF indicator
lamp does not light up during the system self-
test ,then the system is malfunctioning. The
front-passenger front air bag might be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with
high deceleration. This poses an increased
risk of injury or even fatal injury.
