reset MERCEDES-BENZ SLS AMG GT ROADSTER 2015 C197 Owner's Manual

If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is
arisk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on ahigh
curb or an unpave droad
R you drive too fast over an obstacle ,e.g. a
curb or ahole in the road
R ah eavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body,t he under-
carriage, chassis parts, wheels or tires
could be damaged withou tthe damage
being visible. Components damaged in this way can unexpectedly fail or, in the case of
an accident, no longer withstand the strain
they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather betwee nthe
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system, they can catch fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If on con-
tinuing yourj ourney you notice that driving
safety is impaired, pullo ver and stop the
vehicle immediately,p aying attention to
road and traffic conditions. In such cases,
visit aqualified specialist workshop. Declarations of conformity

(OCS)
How the Occupant Classification Sys-
tem works The Occupant Classification System (OCS)
categorize sthe occupant on the front-
passenger sea tusing aw eigh tsensor. The
front-passenger front ai rbag and the front-
passenger knee ba gare deactivate dauto-
matically for certain weight categories. The
00730074 indicator lamp shows yo uthe cur-
rent status. If the 00730074indicator lamp
lights up ,the front-passenger front ai rbag
and the front-passenger knee ba gare disa-
bled.
The system doe snot deactivate:
R the front-passenger sid eimpact ai rbag
R the front-passenger hea dbag
R the Emergency Tensioning Devices 42
Occupant safetySafety

To be classified correctly, the frontp
assenger
must sit:
R with the seat belt fastened correctly
R in ap osition that is as upright as possible
with their back against the seat backrest
R with their feet on the floor
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by lean-
ing on armrests), OCS may not be able to
approximate the occupant's weight category.
In order to determin ewhether or not the front
passenger has been detected, both the driver and the frontp assenger should observe the
00730074 indicator lamp.
If the front-passenger seat, the seat cover or the seat cushion are damaged, have the nec- essary repair work carried out at an author-
ized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories
that have been approved by Mercedes-Benz. G
WARNING
If the 00730074 indicator lamp lights up when
the front-passenger seat is occupied by an
adult or alarger person, ask the passenger to
reposition themselves on the seat so that the
00730074 indicator lamp goes out.
In the event of acollision, the air bag control
unit will not allow front-passenger fronta ir
bag and front-passenger knee bag deploy-
ment when the OCS has classified the front-
passenger occupant as weighing as much as
or less than atypical 12-month-old child in a
standard child restraint or if the front-
passenger seat is classified as being unoccu-
pied.
If OCS has detected that the frontp assenger
weighs the same as or less than atypical 12-
month-old child in astandard child restraint
system, the 00730074indicator lamp lights
up when the engine is started and remains lit. This indicates that the front-passenger front
air bag is deactivated.
If OCS determines that the front-passenger
seat is unoccupied, the 00730074indicator lamp lights up once the engine has been
started and remains lit. This shows that the
front-passenger fronta
ir bag and front-
passenger knee bag are deactivated.
If OCS determines that the frontp assenger
weighs more than atypical 12 montho ld child
in as tandard child restraint system and clas-
sifies this as asmall person (e.g. ateenager or
small adult), the 00730074indicator lamp
lights up for approximately 6seconds when
the engine is started. Dependin gonoccupant
weight sensor readings from the seat, it will
then remain illuminated or go out. If the
00730074 indicator lamp is illuminated, the
front-passenger fronta ir bag is deactivated.
With the 00730074 indicator lamp out, the
front-passenger fronta ir bag and front-
passenger knee bag are deactivated.
If OCS has determined that the front
passenger is an adult or medium sized person, the 00730074 indicator lamp lights up for
approximately 6seconds when the engine is
started and then goes out. This shows that the
front-passenger fronta ir bag and front-
passenger knee bag are activated.
If the 00730074 indicator lamp is illuminated,
the front-passenger fronta ir bag and the
front-passenger knee bag are deactivated and
are not deployed.
If the 00730074 indicator lamp does not light
up, the front-passenger air bag is enabled and
will be deployed:
R in the event of certain frontal impacts
R if the impact exceeds apreset deployment
threshold
R independently of the other air bags
If the front-passenger air bag is deployed, the
rate of inflation is influenced by:
R the rate of vehicle deceleration as assessed
by the air bag control unit
R the frontp assenger's weight category as
determined by the OCS
