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).

Importantsafetynotes
GWARNING
The function of the head restraint may be
impaired if you:
Rattach objects such as coat hangers to the
head restraints, for example
Ruse head restraint covers
If you do so, the head restraintscannot fulfill
their intended protective function in the event
of an accident. In addition, objects attached
to the head restraintscould endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any objects to the head
restraintsand do not use head restraint
covers.
NECK-PRO head restraints/NECK-PRO luxury
head restraintsincrease protection of the
driver'sand front-passenger's head and
neck. In the event ofarear collision of a
certain severity, the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver'sand the front-passenger seats
are moved forwards and upwards. This
provides better head support.
If the NECK-PRO head restraints/NECK-PRO
luxury head restraintshave been triggered in
an accident, reset the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver'sand front-passenger seats
(Ypage 54). Otherwise, the additional
protection will not be available in the event of
another rear-end collision. NECK-PRO head
restraints/NECK-PRO luxury head restraints
that have been triggered are moved forwards
and can no longer be adjusted.
Mercedes-Benz recommends that you have

Driving safety systems
Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lockBrakingSystem)
(Ypage 66)
RBAS (BrakeAssistSystem) (Ypage 67)
RBAS PLUS (BrakeAssistSystem Plus)
(Ypage 67)
RESP®(ElectronicStabilityProgram)
(Ypage 68)
REBD (ElectronicBrake forceDistribution)
(Ypage 71)
RADAPTIVE BRAKE (Ypage 72)
RPRE-SAFE®Brake (Ypage 72)
Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front,for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road, weather and traffic
conditionsand maintainasafe distancefrom
thevehicle in front. Drive carefully.
iThe driving safety systems describedonly
work as effectivelyaspossible when there
is adequatecontactbetween thetires and
theroad surface. Pleasepay special
attentiontothenotesontires,
recommendedminimumtire tread depths,
etc.(Ypage 334).
In wintry drivingconditions, always use
winter tires (M+S tires) and if necessary,
snowchains. Only in this way will the
drivingsafetysystems described in this
section work as effectively as possible.
ABS (Anti-lock BrakingSystem)
Important safety notes
iObserve the "Importantsafetynotes"
section(Ypage 66).
GWARNING
If ABSisfaulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully.Have ABS checked
immediately ataqualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Ypage 267) and
displaymessages which may be shown in the
instrument cluster (Ypage 238).
ABS regulates brake pressure in suchaway
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.

Asaresult, BAS PLUS may not intervene in all
critical situations. There isarisk of an
accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In particular, the detection of obstacles can
be impaired if there is:
Rdirt on the sensorsoranythingelse
covering the sensors
Rsnow or heavy rain
Rinterference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ranarrow vehicle travelinginfront, e.g. a
motorbike
Ravehicle travelinginfrontonadifferent line
relative to the center of your vehicle
Following damage to the frontend of the
vehicle, have the configurationand operation
of the radarsensorschecked ataqualified
specialist workshop. This also applies to
collisions at low speeds where thereisno
visible damage to the frontofthe vehicle.
Braking assistance
To preventacollision with the vehicle in front,
BAS PLUS calculates the brake force
necessary if:
Ryou approach an obstacle, and
RBAS PLUS has detectedarisk of collision
When driving ataspeed under 20 mph
(30 km/h):ifyou depress the brake pedal,
BAS PLUS is activated. The increase in brake
pressure will be carried out at the last
possible moment.
When driving ataspeed greater than
20 mph (30 km/h):ifyou depress the brake
pedal sharply, BAS PLUS automatically raises
the brake pressure toavalue adapted to the
traffic situation.
If BAS PLUS demands particularly high
braking force, preventative passenger
protection measures (PRE-SAFE®)are
activated simultaneously.
XKeep the brake pedal depressed until the
emergencybraking situation is over.
ABS preventsthe wheels from locking.
BAS PLUS is deactivated and the brakes
function as usual if:
Ryou release the brake pedal
Rthere is no longerarisk of collision
Rno obstacle is detected in front of your
vehicle
ESP®(Electronic Stability Program)
Important safety notes
iObserve the "Important safety notes"
section (Ypage 66).
GWARNING
If ESP®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP®checked at a
qualified specialist workshop.
!Vehicles with 4MATIC: switch off the
ignition when the parking brake is being
tested onabrake dynamometer.
Application of the brakes by ESP®may
otherwise destroy the brake system.
