Air bags
Introduction
The air bag installatio npointisi dentified by the
label AI RBAG.
An air bag supplements acorrectly fastened
seat belt.H owever,itisnotintended as asub-
stitut efor th eseat belt.A ir bags provide addi-
tional protection in th eeven tofana ccident.
Not all air bags are deployed in an accident. The
various air bag systems work independently of
each other (
Ypage 54).
Occupant safety47
Safety
Z

There is, however, no system availabletoday
that can completely rule out injury or death.
It is also not possible to rule out arisk of injury
caused by an air bag due to the high speed at
which the air bag must be deployed.
Important safety notes
GWARNING
If you do not sit in the corrects eat position,
the air bag cannot protec tasintended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, alwaysm ake
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sittin gcorrectly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
RCorrectly adjust the seats before driving off.
Always make sure the seat backrest sare
positioned as close to the vertical as possible.
The center of the head restraints should sup-
port the back of the head at about eye level.
RMove the driver's and front-passenger seat as
far back as possible. The driver's seat position
must be such that the vehicle can be driven
safely.
RKeep hands on the outside of the steering
wheel rim. This allows the air bag to deploy
fully.
RAlways sit with your back against the seat
backrest when driving. Do not lean forward,
on the door or against the side window. Oth-
erwise, you are in the air bag deployment
area.
RAlways keep your feet in the footwell in front
of the seat. Do not,f or example, place your
feet on the dashboard. Otherwise, your feet
are in the air bag deployment area.
RSuitable restraint systems must alwaysb e
used for persons under 5ft(1.50 m) in height.
The seat belt cannot be worn correctly by
persons who do not reach this height. If children are also traveling in the vehicle,
please take note of the followingp
oints.
RChild restraint systems should preferably be
installed on the rear seats.
ROnly secureachild on the front-passenger
seat in arearward-facing child restraint sys-
tem if the front-passenger front air bag is
deactivated. If the PASSENGER AIR BAG OFF
indicator lamp is permanently lit, the front-
passenger front air bag is deactivated
(
Ypage 44).
RMake sure you observe the instructions and
safety notes on "Occupan t Classification Sys-
tem (OCS)" (Ypage 50) and "Children in the
vehicle" (Ypage 56), as well as the child
restraint system manufacturer's installation
instructions.
Objects in the passenger compartment
could prevent an air bag from functioning
properly. To prevent risks due to the required
air bag speed after deployment, ensure the fol-
lowing before starting the journey:
Rthere are no persons, animals or objects
between the vehicle occupantsa nd an air
bag.
Rthere are no object sbetween the seat, door
and B-pillar.
Rno hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
Rno accessories, such as cup holders, are
attached to the vehicle within the deployment
area of an air bag, e.g. to doors or side win-
dows.
Rthere are no heavy, sharp or fragile object sin
the pocketsofi tems of clothing. Such items
should be suitably stowed elsewhere.
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.

Rarms
In the event of aside impact, the side impact air
bag is deploye donthe side on which the impact
occurs.
The side impact air bag on the front-passenger
side deploys under the following conditions:
Rthe OCS system detects that the front-
passenger seatiso ccupied or
Rthe belttongue has engaged in the beltb uckle
of the front-passenger seat.
If the beltt ongue has engaged in the beltb uckle,
the side impact air bag on the front-passenger

Occupant Classificatio nSystem
(OCS)
Introduction
The Occupant Classification System (OCS) cat-
egorizes the personint he front-passenger seat.
Depending on that result, the front-passenger
front air bag is either enabled or deactivated.
The syste mdoes not disable:
Rthe side impact air bag
Rthe window curtai nair bag
Rthe Emergency Tensioning Devices
Conditions
To be classified correctly ,the front passenger
must sit:
Rwith the seatb eltfastened correctly
Rin an almost upright position with their back
against the seatb ackrest
Rwith their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce afals ec lassifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selve sonav ehiclea rmrest
Rsits in such awaythat their weight is raised
from the seatc ushion
If it is absolutely necessary to instal lachild
restraint syste monthe front-passenger seat, be
sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g.
cushions. The entire bas eofthe child restraint
syste mmust alway srest on the seatc ushion of
the front-passenger seat. The backres tofthe
forward-facing child restraint syste mmust lie as
flat as possible against the backres tofthe front-
passenger seat.
The child restraint syste mmust not touch the
roof or be subjected to aloadbyt he head
restraint. Adjust the angl eofthe seatb ackrest
and the headr estraint position accordingly.
Only then can OCS be guaranteed to function
correctly .Always observe the child restraint sys-
tem manufacturer's installation instructions.

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
bag is activated. If, in the case of an accident,
all deployment criteria are met, the front-
passenger fronta ir bag is deployed.
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.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
fronta ir bag is correct.
GWARNING
If you secure achild in achild restraint system
on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger fronta ir bag can

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.

not be deployed in the event of an accident. In
this case, the front-passenger front air bag
cannot perform its intended protective func-
tion, e.g. when aperson is seated in the front-
passenger seat.
That person could ,for example ,come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board .This poses an increased risk of injury or
even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the front-
passenger seat is correct and the front-
passenger front air bag is enable dordisa-
bled in accordance with the person in the
