Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.
Read the information on qualified specialist
workshops (Y page
32).Occupant safety
Restraint system introduction
The restraint system can reduce the risk of
vehicle occupants coming into contact with
parts of the vehicle's interior in the event of an
accident. In the event of an accident, the
restraint system can also reduce the forces to
which the vehicle occupants are subjected.
The restraint system includes the following
components:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing system
The various components of the restraint sys-
tem work complementary to one another. They
can only perform their intended protective
function if all vehicle occupants:
R have correctly fastened their seat belt
( Y page

49)
R have correctly adjusted their seat and head
restraint ( Y page 87)
As the driver, you must also ensure that the
driver's seat is in the correct position in rela-
tion to the pedals and the steering wheel.
Depending on your vehicle's equipment, you
can also adjust the steering wheel. Observe
the information relating to the correct driver's
seat position (Y page 87).
Additionally, you must ensure that an air bag
can deploy freely ( Y page 51).
The air bag is supplementary to a correctly fas-
tened seat belt. As an additional safety device,
the air bag increases the level of protection for
vehicle occupants in the event of an accident.
If the protection provided by the seat belt is sufficient, the air bags do not deploy. Further-
more, in the event of an accident, only air bags
which provide greater protection in the given
accident situation deploy. However, seat belts
and air bags generally do not protect against
objects penetrating the vehicle from the out-
side.
Information on how the restraint system oper-
ates can be found in "Deployment of the Emer-
gency Tensioning Devices and air bags"
( Y page

58).
See "Children in the vehicle" for information
on infants and children traveling with you in
the vehicle restraint systems for infants and
children ( Y page 60). 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 for a person with physical dis-
abilities, contact a Mercedes-Benz Commercial
Van Centerfor details. USA only: contact our
Mercedes-Benz Customer Assistance Center
for details at 1‑877 ‑762‑8267. 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 6 restraint system warning lamp on
the instrument cluster lights up when the igni-
tion is switched on. It goes out no later than a
few seconds after the vehicle is started. The
restraint system is operational. 46
Occupant safety
Safety

A malfunction has occurred if the
6
restraint 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 be trig-
gered as intended in the event of an acci-
dent. This may affect the Emergency Ten-
sioning Devices or air bags, for example.
There is a risk of injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp
: is
part of the Occupant Classification System
(OCS).
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the co-driver's
air bag.
If the PASSENGER AIR BAG OFF indicator
lamp:
R is lit, the co-driver's air bag is deactivated.
It will not be deployed in the event of an
accident.
R is not lit , the co-driver's air bag is enabled.
If, in the event of an accident, all deploy-
ment criteria are met, the co-driver's air bag
is deployed. Depending on the person in the co-driver's
seat, the co-driver's air bag must be either
deactivated or enabled; see the following
points. You must make sure of this both
before and during a journey.
R Children in a child restraint system:
whether the co-driver's air bag is enabled or
deactivated depends on the installed child
restraint system and the age and size of the
child. It is thus essential to comply with the
instructions on the "Occupant Classification
System (OCS)" ( Y page
54) and "Children
in the vehicle" ( Y page 60). Information is
also included here on rearward or forward-
facing child restraint systems on the co-driv-
er's seat.
R All other persons: depending on the classi-
fication of the person in the co-driver's seat,
the co-driver's air bag must be either ena-
bled or deactivated (Y page 54). Be sure to observe the notes on "Seat belts"
( Y page 47) and "Air bags" (Y page 51).
Information is also included here on the cor-
rect seating position. Seat belts
Introduction A correctly fastened seat belt is the most
effective means of limiting the movement of a
vehicle occupant during a collision or in the
event that the vehicle overturns. This reduces
the risk of vehicle occupants coming into con-
tact with parts of the vehicle interior or being
ejected from it. Furthermore, the seat belt
helps to keep the vehicle occupant in the best
position in relation to a deployed air bag.
The seat belt system consists of:
R seat belts
R Emergency Tensioning Devices for the front
seat belts
The seat belt system includes a belt force
limiter for the respective seat if the vehicle
is equipped with a front air bag.
If the seat belt is pulled quickly or suddenly
from the belt outlet, the inertia reel locks. The
belt strap cannot be pulled out further.
In an impact, the Emergency Tensioning
Device tightens the belt to pull it close to the
body. It does not pull the vehicle occupant Occupant safety

Safety Z

Fastening and adjusting seat belts
Observe the safety notes on seat belts
(Y page
48) and the notes on the correct use
of the seat belt (Y page 49). Basic diagram
X Adjust the seat (Y page
87).
The seat backrest must be in an almost ver-
tical position.
X Pull the seat belt out smoothly from the belt
outlet and engage belt tongue ; into belt
buckle :.
The shoulder section of the belt must
always be routed across the center of the
shoulder. If necessary, adjust the belt out-
let.
X If necessary, pull upwards on the seat belt
in front of your chest so that the belt sits
tightly across your body.
The shoulder section of the belt must always
be routed across the center of the shoulder. If
necessary, adjust the belt outlet. X To raise: slide the belt outlet upwards.
The belt outlet engages in a number of dif-
ferent positions.
X To lower: slide the belt outlet downwards
while pressing belt outlet release =.
X Let go of belt outlet release = in the
desired position and make sure that the belt
outlet engages.
All seat belts in the vehicle, with the exception
of the driver's seat belt, are equipped with a
child seat lock, to which a child restraint sys-
tem can be secured safely. You can find fur-
ther information under "Child seat lock"
(Y page

61). Releasing seat belts !
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop.
X Press the release button in the belt buckle,
hold the belt tongue firmly and guide the
belt back.
Belt warning for drivers and co-drivers The 7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle
occupants must wear their seat belts cor-
rectly. It may light up continuously or flash. In
addition, there may be a warning tone.
Regardless of whether the driver's seat belt
has already been fastened, the 7 seat belt
warning lamp lights up for six seconds each
time the engine is started. If the front doors
are closed and the driver's or front-passenger
seat belt has not been fastened, the 7 seat
belt warning lamp lights up again after the six
seconds. As soon as the driver's and front-
passenger seat belts are fastened or a front
door is opened again, the 7 seat belt warn-
ing lamp goes out.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. This warning tone stops after
a maximum of six seconds or once the driver's
seat belt is fastened.
If the vehicle's speed exceeds

15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a warn-
ing tone sounds. A warning tone also sounds
with increasing intensity for 60 seconds or
until the driver or front passenger have fas-
tened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again. 50

Occupant Classification System
(OCS)
Introduction The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag is either enabled or
deactivated.
The system does not deactivate:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
Conditions To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in an almost upright position with their back
against the seat backrest
R with their feet resting on the floor, if possi-
ble
If the front passenger does not observe these
conditions, OCS may produce a false classifi-
cation, e.g. because the front passenger:
R transfers their weight by supporting them-

If it is absolutely necessary to install a child
restraint system on the 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.
a cushion. The entire base of the child
restraint system must always rest on the seat
cushion of the front-passenger seat. The back-
rest of the forward-facing child restraint sys-
tem must lie as flat as possible against the
backrest of the front-passenger seat.
The child restraint system must not touch the
roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation and operat-
ing instructions. Occupant Classification System (OCS)
