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.
The restraint system can also reduce the forces to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
RSeat belt system
RAir bags
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 41)
Rhave the seat and head restraint adjusted
properly (Ypage 84)
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Ypage 84). You also have to make sure that an air bag can
inflate properly if deployed(
Ypage 43).
An air bag supplements acorrectly worn 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, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags are not deployed. When an accident occurs, only
the air bags that increase protection in that par-ticular accident situation are deployed. How-
ever, seat belts and air bags generally do not
protect against object spenetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 50).
See "Children in the vehicle" for information on
children traveling with you in the vehicle as well
as on child restraint systems (
Ypage 53).
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 components of the
restraint system to accommodate aperson with
disabilities, contact an authorized Mercedes-
Benz Center for details. USA only: for further
information contact our Customer Assistance
Center at 1-800F OR-MERCEDES
(1‑800‑367‑6372).
Mercedes-Benz recommends that you only use
driving aids which have been approved specifi-
cally for your vehicle by Mercedes-Benz.

Requirements
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 restin gonthe floor, if possible
If the front passenger does not observe these
conditions, OCS may produce afalse classifica-
tion, e.g. because the front passenger:
Rtransfers their weight by supporting them-
selves on avehicle armrest
Rsits in such away that their weight is raised
from the seat cushion
If you install achild restraint system on the
front-passenger seat, be sure to observe the
correctp ositioningofthe child restraint system.
Never place object sunder or behind the child
restraint system, e.g. acushion. The entir ebase
of the child restraint system must alwaysr est 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 aload 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 and operating
instructions.
Occupant Classification System opera-
tion (OCS)
:PASSENGER AIR BAG ON indicator lamp
;PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front air bag is deactivated or
enabled.
XPress the Start/Stop button once or twice, or
turn the SmartKey to position 1or2 in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps must light up simul-
taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up for 60 sec-
onds, subsequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF): the
front-passenger front air bag is able to deploy
in the event of an accident.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front air bag. The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
If the status of the front-passenger front air bag
changes while the vehicle is in motion,ana ir bag
display message appears in the instrument clus-
ter (
Ypage 187). When the front-passenger
seat is occupied, alwaysp ay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front air bag both before and during the journey.

Metho dofoperation
During the firs tstag eofac ollision, the restraint
system control uni tevaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
Rduration
Rdirection
Rintensity
Base dont he evaluation of this data, the
restraint system control uni ttriggers the Emer-
gency Tensioning Devices during afrontalo r
rearc ollision. An Emergency Tensioning Device can only be
triggered, if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational

You are responsible for maintainingthe distance
to the vehicle in front, for vehicle speed, for
braking in good time, and for stayin ginlane.
Always adapt your drivings tyle to suit the pre-
vailing road and weather condition sand main-
tain asafe distance from the vehicle in front.
Drive carefully.
The drivings afetysystems described only work
as effectively as possible when there is ade-
quate contac tbetwee nthe tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tir et read depth setc.int he "Wheels and tires"
section (
Ypage 260).
In wintry drivingc onditions, always use winter
tires (M+S tires) and if necessary, sno wchains.
Only in this way will the drivings afetysystems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
Genera linformation
AB Sregulates brakep ressure in suchaway that
the wheels do not lock when you brake. This
allows you to continue steeringt he vehicle when
braking.
The ! ABSw arnin glamp in the instrument
cluster lightsupw hen the ignition is switched
on. It goes out when the engin eisrunning.
AB Sw orksf romaspeed of about 5mph
(8 km/h), regardless of road-surfacec onditions.
AB Sw orksons lippery surfaces, even when you
only brakeg ently.
Important safetyn otes
iObserve the "Importan tsafetyn otes" sec-
tion (Ypage 56).
GWARNING
If AB Sism alfunctioning, the wheels could
lock when braking. The steerabilitya nd brak-
ing characteristics would be severely affec-
ted. There is an increased danger of skidding and accidents.
Drive on carefully. Have AB Schecked imme-
diately at aqualified specialis tworkshop.
When AB Sismalfunctioning, other systems,
including drivings afetysystems, will also becom
einoperative .Observe the information
on the AB Swarnin glamp (
Ypage 204) and dis-
play messages which may be shown in the
instrumentc luster (
Ypage 179).
Brakes
XIf ABS intervenes: continue to depresst he
brakep edal vigorously until the braking sit-
uation is over.
XTo make afull brake application: depress
the brakep edal with full force.
If AB Sintervenes when braking, you will feel a
pulsing in the brakep edal.
The pulsatin gbrakep edal can be an indication
of hazardous road conditions, and function sasa
reminder to tak eextra care while driving.
BAS (Brake Assist System)

BA So perates in emergenc ybraking situations.
If you depresst he brakepedal quickly, BAS
automatically boostst he braking force, thus
shortening the stopping distance.
