totalavailablepropellant gas, thereby
reducing the risk of injury.Ifthe airbag
control unitrecognizeswithinafew
milliseconds thatthe vehicle is being braked
or accelerated faster than originally
predicted, the front air bag is filled with the
maximum amount of propellant gas available.
The deployment of the front-passenger front
air bag is also influenced by the weight
category of the front passenger, which is
determined by the Occupant Classification
System (OCS) (Ypage 47).
The lighter the passenger-side occupant, the
higher the vehicle deceleration rate required
(predicted at the start of the impact) for
second-stage inflation of the front-passenger
front air bag. In the second stage, the front
air bags are inflated with the maximum
amount of propellant gas available.
The front air bags are not deployed in
situations wherealow impact severity is
predicted. You will then be protected by the
fastened seat belt.
The front-passenger front air bag will only
deploy if:
Rthe system, based on the OCS weight
sensor readings, detectsthat the front-
passenger seat is occupied
Rthe PASSENGER AIR BAG OFF indicator
lamp on the center console is not lit
(Ypage 47)
Rthe air bag control unit predictsahigh
impact severity
Knee bags
Driver's knee bagdeploysunderneath the
steering column and front-passenger knee
bagunderneath the glove box. They
deploy together with the front air bags. They
are designed to operate together with the
front air bags in frontal impacts if certain
thresholds are exceeded. The knee bags
operate at best in conjunction with correctly
positioned and fastened seat belts.
Knee bags provide increased protection for
the driver and front passenger against the risk
of:
Rknee injuries
Rthigh injuries
Rlower leg injuries
Side impact air bags
GWARNING
Using unsuitable seat covers could restrict or
even prevent deployment of the air bags
integrated into the seats. Consequently, the
air bags cannot protect vehicle occupants as
they are designed to do. In addition, the
function of the air bag deactivation system
could be restricted. This poses an increased
risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
GWARNING
Sensors to control the air bags are located in
the doors. Modifications or work not
performed correctly to the doors or door
paneling, as well as damaged doors, can lead
to the function of the sensors being impaired.
The air bags might therefore not function
properly any more. Consequently, the air bags
cannot protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door
paneling carried out ataqualified specialist
workshop.

The pelvis air bags deploy next to and below
the outer seat cushions. They are deployed:
Ron the side on which an impact occurs
Rat the start of an accident withahigh rate
of lateral vehicle deceleration or
acceleration,e.g. inaside impact
Rindependently of the use of the seat belt
Rindependently of the front air bags
Rindependently of the ETDs
If the vehicle rolls over,the pelvis air bags are
generally not deployed. Exception: if the
system detectshigh vehicle deceleration or
acceleration inalateral direction and
determines that deploymentcan offer
additional protection to that providedbythe
seat belt.
Pelvis air bagswill notdeploy in side
impacts which do not exceed the system's
preset deployment thresholds for lateral
acceleration/deceleration.You will then be
protected by the fastened seat belt.
The pelvis air bag on the front-passenger side
is not deployed in the following situations:
ROCS has detected that the front-passenger
seat is unoccupied.
Rthe front-passenger seat belt is not
fastened.
The pelvis air bag on the front-passenger side
will deploy if the front-passenger seat belt is
fastened, regardless of whether the front-
passenger seat is occupied or not.
Window curtain air bags

of protection for the head, but not chest or
arms, of the vehicle occupantsonthe side of
the vehicle on which the impact occurs.
The window curtain air bags are integrated
into the side of the roof frame and deploy in
the area from the A-pillar to the C-pillar.
Window curtain air bags are deployed:
Rat the start of an accident withahigh rate
of lateral vehicle deceleration or
acceleration, e.g. inaside impact
Ron the side on which an impactoccurs

Occupant Classification System
(OCS)
Method of operation
GWARNING
If theindicator lamp illuminates
when an adult or someone larger thanasmall
individual is in the front-passenger seat, have
the front passenger reposition himself or
herself in the seat until the
indicator lamp goes out.
In the event ofacollision, the air bag control
unit will not allow front-passenger front air
bag deployment when the OCS has classified
the front-passenger seat occupant as
weighing as much as or less thanatypical 12-
month-old child inastandard child restraint

GWARNING
The front-passenger front air bag and front passenger knee bag
may not be triggered in the event of an accident.
There is an increased risk of injury.
XPull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.
XSecure the vehicle against rolling away (Ypage 167).
XSwitch the ignition off.
XHave the occupant get out of the vehicle.
XKeep the seat unoccupied, close the front-passenger door and
switch on the ignition.
XObserve the PASSENGER AIR BAG OFF indicator lamp in the
center console and the multifunction displayand check the
following:
Seat unoccupied and ignition switched on:
Rthe PASSENGER AIR BAG OFF indicator lamp must light up and
remain lit. If the indicator lamp is on, OCS has disabled the front-
passenger air bag and front-passenger knee bag (Ypage 47).
RtheFront Passenger Airbag Enabled See Operator's

XWait foraperiod of at least 60 seconds until the necessary
system checkshave been completed.
XMake sure that the displaymessages do not appearinthe
multifunction display.
If these conditionsare fulfilled,the front-passenger seat can be
occupied again. Whether the PASSENGER AIR BAG OFF indicator
lamp remains lit or goes out depends on how OCS classifies the
occupant.
If the conditionsare not fulfilled,the system is not operating
correctly.
