2015 MERCEDES-BENZ SLK-Class airbag off

PASSENGER AIR BAG OFF indicator lamp
(Y page 41).
Your vehicle has two-stage front air bags.
During the first deployment stage, the front
air bag fills with propellant gas which reduces the risk of injury. The second stage is then
triggered within milliseconds, filling the front
air bag with the maximum amount of propel-
lant gas.
The deployment thresholds for the Emer-
gency Tensioning Devices and air bags are
calculated on the basis of the vehicle decel-
eration or acceleration occurring at various
points in the vehicle. This process is pre-emp-
tive in nature. The air bag must be deployed
on time, at the start of the collision.
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen- tially determined by:
R distribution of the force during the impact
R collision angle
R deformation characteristics of the vehicle
R characteristics of the object with which the
vehicle has collided
Factors which can only be seen and measured after the collision has occurred do not play a
decisive role in the deployment of an airbag,
nor do they provide an indication of air bag
deployment.
The vehicle may be considerably deformed
without an air bag being deployed. This is the
case if only relatively easily deformable parts
have been hit and a high rate of deceleration
has not been reached. Conversely, an air bag may be deployed even though the vehicle suf-
fers only minor deformation. This is the case
if, for example, very rigid vehicle parts such as the longitudinal body members are hit in an
accident and the rate of deceleration is suffi-
cient. If the restraint system control unit detects a
side impact or an overturn situation, the rel-
evant restraint system components are acti-
vated independently of one another depend-
ing on the apparent type of accident. If addi-
tional protection for the vehicle occupants is determined in this situation, the belt tension-
ers are also triggered.
R Sidebag on the side on which the impact
occurs, independently of the belt tensioner
and of the use of the seat belt on the driv-
er's seat
The sidebag on the front-passenger side
deploys under the following conditions:
- the OCS system detects that the front-
passenger seat is occupied or
- the belt tongue has engaged in the belt
buckle of the front-passenger seat.
R Headbag on the side on which the impact
occurs, independently of the use of the seat
belt and independently of whether the
front-passenger seat is occupied
R Headbags on the driver's and front-
passenger sides in certain overturn situa-
tions if the system determines that they
can offer additional protection to that pro-
vided by the seat belt
i Not all air bags are deployed in an acci-
dent. The various air bag systems work
independently of each other.
How the air bag system works is deter-
mined by the severity of the accident detec- ted, especially the vehicle deceleration or
acceleration, and the apparent type of acci- dent:
R frontal collision
R side impact
R rollover Occupant safety

ual The front-passenger air bag and front-passenger knee bag are
deactivated during the journey, although:
R an adult
or
R a person larger than a certain size is occupying the front-
passenger seat
If additional forces are applied to the seat, the system may inter-
pret the occupant's weight as lower than it actually is.
G WARNING
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.
X Pull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.
X Secure the vehicle against rolling away (Y page 161).
X Switch the ignition off.
X Have the occupant get out of the vehicle.
X Keep the seat unoccupied, close the front-passenger door and
switch on the ignition.
X Observe the PASSENGER AIR BAG OFF indicator lamp in the
center console and the multifunction display and check the fol-
lowing:
Seat unoccupied and ignition switched on:
R the PASSENGER AIR BAG OFF indicator lamp must light up
and remain lit. If the indicator lamp is on, OCS has deactivated
the front-passenger air bag and front-passenger knee bag
(Y page 49).

X Wait for a period of at least 60 seconds until the necessary sys-
tem checks have been completed.
X Make sure that the display messages do not appear in the mul-
tifunction display.
If these conditions are 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 conditions are not fulfilled, the system is not operating cor- rectly. Display

ual The front-passenger air bag and front-passenger knee bag are
enabled during the journey, even though:
R a child, a small adult or an object weighing less than the sys-
tem's weight threshold is located on the front-passenger seat
or
R the front-passenger seat is unoccupied
The system may detect objects or forces applying additional
weight on the seat.
G WARNING
The front-passenger front air bag and front-passenger knee bag
may be triggered unintentionally.
There is an increased risk of injury. X Pull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions.
X Secure the vehicle against rolling away (Y page 161).
X Switch the ignition off.
X Open the front-passenger door.
X Remove the child and the child restraint system from the front-
passenger seat.
X Make sure that there are no objects on the seat adding to the
weight.
The system may otherwise detect the additional weight and
interpret the seat occupant's weight as greater than it actually
is.
X Keep the seat unoccupied, close the front-passenger door and
switch on the ignition.
