Modifications to the restraint systemscould
result in them not functioning properly any
more. The restraint systemscould then no
longer protect vehicle occupants as they are
designed to do and could fail in the eventof
an accidentoractivateunexpectedly, for
example. Thereisanincreased risk of injury.
Never modify partsoftherestraint systems.
Do notattempttomodify the wiring as well as
electronic components or their software.
If it is necessary to modify an air bag system
to accommodateaperson with disabilities,
contact an authorized Mercedes-Benz center.

In this section,you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint system consistsof:
RSeat belts
RChild restraint systems
RLATCH-type (ISOFIX) child seat securing
system
Additional protection is provided by:
RSRS (Supplemental Restraint System)
RNECK-PRO head restraints/NECK-PRO
luxury head restraints
RPRE-SAFE®
RAir bag system components with:
-PASSENGER AIR BAG OFF indicator lamp
-Front-passenger seat with Occupant
Classification System (OCS)
The different air bag systems work
independently of each other. The protective
functions of the system work in conjunction
with each other. Not all air bags are deployed
in an accident.

Occupant Classification System (OCS)
categories the occupant on the front-
passenger seat usingaweight sensor.
The front-passenger front air bag and the
front-passenger knee bag are deactivated
automatically for certain weight categories.
The PASSENGER AIR BAG OFF indicator lamp
shows you the current status.
If the PASSENGER AIR BAG OFF indicator
lamp lights up, the front-passenger front air
bag and the front-passenger knee bag are
disabled.
The system does not deactivate:
Rthe side impact air bag
Rthe pelvis air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rinaposition that is as upright as possible
with their back against the seat backrest
Rwith their feet on the floor
The OCS weight sensor reading is affected if
the occupant's weight is transferred, e.g. by
leaning on the armrest.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at a
qualified specialist workshop.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should always observe the PASSENGER AIR
BAG OFF indicator lamp as an indication of
whether or not the front passenger is
positioned correctly. Observe also the air bag
displaymessages that can be displayed in the
instrumentcluster (Ypage 244).
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy.
The OCS may have detected that the seat:
Ris empty or occupied by the weight of a
typical child up to twelve months old,
seated inachild restraint system
Ris occupied byasmall individual, such as a
young teenager orasmall adult
Ris occupied byachild inachild restraint
system whose weight is greater than that
ofatypical twelve monthold child.
These are examples of when the OCS
deactivates the front-passenger front air bag
and front-passenger knee bag. Deactivation
takes place although the collision fulfills the
criteria for deploying the driver's air bag.
For further information,see "Air bag display
messages" (Ypage 244).

Centerbefore seating any child on the front
passenger seat.
GWARNING
Objects between the seat surface and the
child restraint system could affect the
function of the OCS. This could result in the
front-passenger frontair bag not functioning
as intended during an accident. This poses an
increased risk of injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. Make
sure that the bottom and back of the child
restraint system make full contact with the
front-passenger seat cushion and backrest.
Always comply with the child restraint system
manufacturer's installation instructions.

Rif, on vehicles with DISTRONIC PLUS,the
radar sensor system detectsanimminent
dangerofcollision in certain situations.
Rin critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely.
PRE-SAFE®takes the following measures
depending on the hazardous situation
detected:
Rthe front seat belts are pre-tensioned.
Rthe front-passenger seat is adjusted if it is
in an unfavorable position.
Rvehicles withamulticontour seat or active
multicontour seat: the air pressure in the
side bolsters of the seat cushion and
backrest is increased.
Rif the vehicle skids, the sliding sunroof and
the side windows are closed so that only a
small gap remains.
If the hazardous situation passes without
resulting in an accident,PRE-SAFE®slackens
the belt pre-tensioning. The air pressure in
the side bolsters on the multicontour seat/
active multicontour seat is reduced again. All
settings made by PRE-SAFE®can then be
reversed.
If the seat belts are not released:
XWhen the vehicle is stationary, move the
backrest or seat back slightly.
The seat belt pre-tensioningisreduced and
the lockingmechanism is released.
Information about seat belt adjustment, a
conveniencefunction integrated into PRE-
SAFE®,can be found in the "Seat belt
adjustment" section (Ypage 57).
Seat belts
Important safety notes
GWARNING
The seat belt does not offer the intended level
of protection if the backrest is not in the
upright position. When braking or in the event
of an accident,you 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 make sure that the seat
is in the upright position.
GWARNING
Seat belts cannot protect as intended, if:
Rthey are damaged, extremely dirty,
bleached or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency TensioningDevices or the
belt anchorage has been modified.
Damage caused to seat belts in an accident
may not be visible, e.g. by splinters of glass.
Modified or damaged seat belts can tear or
fail, for example in the event of an accident.
Modified Emergency TensioningDevices may
be deployed unintentionally or fail to be
deployed when required. There is an
increased risk of injury, possibly even fatal.
Never modify seat belts, Emergency
TensioningDevices, seat belt anchorages and
inertia reels. Ensure that seat belts are not
damaged or worn and are clean.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz.
The use of seat belts and infant and child
restraint systems is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadianprovinces
