Indicator Lamp - Mercedes-Benz SLS AMG GT Coupe Operator's Manual

To be classified correctly, the front passenger
must sit:
with the seat belt fastened correctly
R
in a position that is as upright as possible
R
with their back against the seat backrest
with their feet on the floor
R
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by
leaning on armrests), OCS may not be able to
approximate the occupant's weight category.
In order to determine whether or not the front
passenger has been detected, both the driver
and the front passenger should observe the

45 indicator lamp.

If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at an
authorized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.

WARNING
If the 45 indicator lamp lights up when
the front-passenger seat is occupied by an
adult or a larger person, ask the passenger to
reposition themselves on the seat so that the
45 indicator lamp goes out.
In the event of a collision, the air bag control
unit will not allow front-passenger front air
bag and front-passenger knee bag
deployment when the OCS has classified the
front-passenger occupant as weighing as
much as or less than a typical 12-month-old
child in a standard child restraint or if the
front-passenger seat is classified as being
unoccupied.
If OCS has detected that the front passenger
weighs the same as or less than a typical 12-
month-old child in a standard child restraint
system, the 45 indicator lamp lights
up when the engine is started and remains lit.
This indicates that the front-passenger front
air bag is deactivated.
Occupant safety
If OCS determines that the front-passenger
seat is unoccupied, the 45 indicator
lamp lights up once the engine has been
started and remains lit. This shows that the
front-passenger front air bag and front-
passenger knee bag are deactivated.
If OCS determines that the front passenger
weighs more than a typical 12 month old child
in a standard child restraint system and
classifies this as a small person (e.g. a
teenager or small adult), the 45
indicator lamp lights up for approximately 6
seconds when the engine is started.
Depending on occupant weight sensor
readings from the seat, it will then remain
illuminated or go out. If the 45
indicator lamp is illuminated, the front-
passenger front air bag is deactivated. With
the 45 indicator lamp out, the front-
passenger front air bag and front-passenger
knee bag are deactivated.
If OCS has determined that the front
passenger is an adult or medium sized person,
the 45 indicator lamp lights up for
approximately 6 seconds when the engine is
started and then goes out. This shows that the
front-passenger front air bag and front-
passenger knee bag are activated.
If the 45 indicator lamp is illuminated,
the front-passenger front air bag and the
front-passenger knee bag are deactivated and
are not deployed.
If the 45 indicator lamp does not light
up, the front-passenger air bag is enabled and
will be deployed:
in the event of certain frontal impacts
R
if the impact exceeds a preset deployment
R
threshold
independently of the other air bags
R
If the front-passenger air bag is deployed, the
rate of inflation is influenced by:
the rate of vehicle deceleration as assessed
R
by the air bag control unit
the front passenger's weight category as
R
determined by the OCS
