Occupant safety
Introduction to the restraint system
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. 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 43)
Rhave adjusted their seat and head restraint
properly (
Ypage 97).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (
Ypage 96).
You also have to make sure that an air bag can
inflate properly if deployed (
Ypage 46).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air
bag increases the level of protection for vehi-
cle occupants in the event of an accident. For
example, if, in the event of an accident, the
protection offered by the seat belt is suffi-
cient, the air bags are not deployed. When an
accident occurs, only the air bags that
increase protection in that particular accident
situation are deployed. However, seat belts
and air bags generally do not protect against
objects penetrating the vehicle from the out-
side.
Information on restraint system operation
can be found under "Triggering of the Emer-
gency Tensioning Devices and air bags"
(
Ypage 54).

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).
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 run-
ning. Therefore, malfunctions can be detec-
ted in good time.
The 6 restraint system warning lamp in
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
components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
Rdoes not light up after the ignition is
switched on
Rdoes not go out after a few seconds with
the engine running
Rlights up again while the engine is running
GWARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG OFF indicator lamp :
and PASSENGER AIR BAG ON indicator
lamp ;are part of the Occupant Classifica-
tion System (OCS).
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up: the
front-passenger front air bag is enabled. If,
in the event of an accident, all deployment
criteria are met, the front-passenger front
air bag is deployed.
RPASSENGER AIR BAG OFF lights up: the
front-passenger front air bag is deactiva-
ted. It will then not be deployed in the event of an accident.

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.
Basic illustration
XPress release button :, hold belt
tongue ;firmly and guide back towards
belt loop =.
Seat belt adjustment
AMG vehicles: the "seat-belt adjustment"
function is not available.
The seat-belt adjustment is an integral part of
the PRE-SAFE
®convenience function. This
function adjusts the driver's and front-
passenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
Rthe belt tongue is engaged in the buckle
and
Rthe ignition is switched on
The seat-belt adjustment will apply a certain
retraction force if any slack is detected between the vehicle occupant and the seat
belt. Do not hold on to the seat belt tightly
while it is adjusting.
You can switch the seat-belt adjustment on
and off in the on-board computer
(
Ypage 207).
Belt warning for the driver and front
passenger
The
7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle
occupants must wear their seat belts. 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 7seat belt
warning lamp lights up for six seconds each
time the engine is started. If, after
six seconds, the driver or front-passenger
seat belt has not been fastened and the doors
are closed, the 7seat belt warning lamp
lights up. As soon as the driver's and front-
passenger seat belts are fastened or a front
door is opened again, the 7seat belt
warning lamp goes out.
If the driver's seat belt is not fastened after
the engine is started, an additional warning
tone will sound. This warning tone stops after
six seconds or when 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
warning tone sounds. A warning tone also
sounds with increasing intensity for
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver or front passenger unfasten their
seat belts during the journey, the seat belt
warning is activated again.
iFor more information on the 7seat
belt warning lamp, see "
Warning and indi-
cator lamps in the instrument cluster, seat belts" (

Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag and front-passenger
knee bag are either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe front-passenger head bag
Rthe Emergency Tensioning Devices
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 possi-
ble
If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, 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 you install a child restraint system on the
front-passenger seat, be sure to observe the
correct positioning of the child restraint sys-
tem. 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 back- rest and the head restraint position accord-
ingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation instruc-
tions.
Occupant Classification System opera-
tion (OCS)
:PASSENGER AIR BAG OFF indicator lamp
;PASSENGER AIR BAG ON 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 1or 2in
the ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
must light up simultaneously for approx-
imately six seconds.
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up: the
front-passenger front air bag is enabled. If,
in the event of an accident, all deployment
criteria are met, the front-passenger front
air bag is deployed.
RPASSENGER AIR BAG OFF lights up: the
front-passenger front air bag is deactiva-
ted. It will then not be deployed in the event
of an accident.

BAS (Brake Assist System)
General information
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-
tion (
Ypage 61).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.

COLLISION PREVENTION ASSIST
PLUS
General information
COLLISION PREVENTION ASSIST PLUS con-
sists of a distance warning function with an
autonomous braking function and Adaptive
Brake Assist.
COLLISION PREVENTION ASSIST PLUS can
help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the
effects of such a collision.
If COLLISION PREVENTION ASSIST PLUS
detects that there is a risk of a collision, you
will be warned visually and acoustically. If you
do not react to the visual and audible collision
warning, autonomous braking can be initiated
in critical situations. If you apply the brake
yourself in a critical situation, the COLLISION
PREVENTION ASSIST PLUS adaptive Brake
Assist assists you.
Important safety notes
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Rnew vehicles or after a service on the COL-
LISION PREVENTION ASSIST PLUS system
Observe the notes in the section on break-
ing-in (
Ypage 138).
Following damage to the front end of the vehi- cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.
Activating or deactivating
COLLISION PREVENTION ASSIST PLUS is
