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.
Furthermore, the restraint system may also
reduce the forces exerted on the vehicle occu-
pants when an accident occurs.
The restraint system includes:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing system
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 43)
Radjust their seat and head restraint properly
(Ypage 96). The driver is also responsible for ensuring that
the steering wheel has been correctly posi-
tioned. Observe the information relating to the
correct driver's seat position (
Ypage 96).
Always ensure the air bag can inflate properly if
deployed (
Ypage 45).
An air bag supplements a correctly fastened
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 the protection already provided by a cor-
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 event of
an accident are deployed. 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 Emergency Ten-
sioning Devices and air bags" (
Ypage 53).
See “Children in the vehicle” for information on
children traveling with you as well as vehicle
restraint systems (
Ypage 57).
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 an air bag system to
accommodate a person with disabilities, con-
tact an authorized Mercedes-Benz Center for
details. USA only: for further information con-
tact our Customer Assistance Center at
1-800-FOR-MERCedes (1‑800‑367‑6372).

Safety

Prerequisites
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their back
against the seat backrest
Rwith their feet resting on the floor, if possible
If the front passenger does not observe these
conditions, OCS may produce a false classifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on a vehicle armrest
Rsits in such a way that their weight is raised
from the seat cushion
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.
cushions. The entire base of the child restraint
system must always rest on the seat cushion of the front-passenger seat. The backrest of the
forward-facing child restraint system 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 sys-
tem manufacturer's installation instructions.
Occupant Classification System opera-
tion (OCS)
PASSENGER AIRBAG OFF indicator lamp :
indicates whether the front-passenger front air
bag is disabled.
XTurn the SmartKey to position 1or 2in the
ignition lock, or in vehicles with KEYLESS-GO,
press the start/stop button once or twice.
The system carries out a self-diagnosis test.
The PASSENGER AIR BAG OFF indicator lamp
must light up for about six seconds.
The PASSENGER AIR BAG OFF indicator lamp
then shows the status of the front-passenger
front air bag. If the status of the front-passenger
front air bag changes whilst the vehicle is in
motion, an air bag display message may appear
in the instrument cluster (
Ypage 209). Always
observe the PASSENGER AIR BAG OFF indicator
lamp when the front-passenger seat is occu-
pied. Make sure that the status of the front-
passenger front air bag is correct before and
during a journey.
If the PASSENGER AIRBAG OFF indicator
lamp:
Rlights up, the front-passenger front air bag is
disabled. It will then not be deployed in the
event of an accident.
Rdoes not light up, the front-passenger front
air bag is enabled. If, in the case of an acci-
dent, all deployment criteria are met, the
front-passenger front air bag is deployed.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person 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
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 enabled or disa-

Problems with the steering wheel heating
ProblemPossible causes/consequences andMSolutions
The steering wheel heat-
ing has switched off pre-
maturely or cannot be
switched on.The on-board voltage is too low because too many electrical consum-
ers are switched on.
XSwitch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting.
Once the battery is sufficiently charged, the steering wheel heating
will switch back on automatically.
