2015 MERCEDES-BENZ SLS AMG GT ROADSTER ECU

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

WARNING
Childre n12years old and under must be
seated and properly secure dinanappropriate
infant restraint, toddle rrestraint, or booster
seat recommende dfor the size and weight of
the child.
The infant or child restraint must be properly
secure dwith the vehicle's seat beltf ullyin
accordance with the child seat manufactur-
er's instructions.
Occupants, especially children, should always
sit as upright as possible,w earthe seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommende dfor the size and weight of the
child.
Childre ncan be kille dorseriouslyi njured by
an inflating air bag.N ote the following impor-
tant information:
R Yourv ehicleise quipped with air bag tech-
nology designed to deactivate the front-
passenger front air bag in yourv ehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of astandard appropriate
child restraint on the front-passenge rseat.
R Ac hild in arear-facing child restraint on the
front-passenge rseat willbes eriously
injured or even kille difthe front-passenger
front air bag inflates in acollision which
coul doccur under some circumstances,
even with the air bag technology installed in yourv ehicle.
R If you install arear-facing child restraint on
the front-passenge rseat, make sure the
00730074 indicator lamp is illuminated,
indicating that the front-passenge rfront air
bag is deactivated. Shoul dthe 00730074
indicator lamp not illuminate or go out while the restraint is installed, please check
installation. Periodically check the
00730074 indicator lamp while driving to
make sure the 00730074indicator lamp is
illuminated. If the 00730074indicator lamp
goes out or remains out, do not transport a child on the front-passenge
rseat until the
system has been repaired.
Ac hild in arear-facing child restraint on the
front-passenge rseat willbes eriously
injured or even kille difthe front-passenger
front air bag inflates.
R If you place achild in aforward-facing child
restraint on the front-passenge rseat:
- move the seat as far back as possible
- use the prope rchild restraint recom-
mended for the age,s ize and weight of
the child
- secure child restraint with the vehicle's
seat belta ccording to the child seat man-
ufacturer's instructions
R For children larger than atypical 12-month-
old child ,the front-passenge rfront air bag
may or may not be activated.
If the driver's air bag deploys,t his does not
mean that the front-passenge rfront air bag
willa lsod eploy.
The OCS may have detected that the seat:
R is empty or occupied by aperso nwith a
weight of up to or less than that of atypical
12-month-old child seated in astandard
child restraint.
R is occupied by asmal lindividual, such as a
young teenage rorasmalladult.
R is occupied by achild in achild restraint
system whos eweight is greater than that of
at ypical 12-month-old child.
These are examples of when the OCS deacti- vates the front-passenge rfront air bag and
front-passenge rknee bag.D eactivation takes
place although the collision fulfills the criteria for deploying the driver's air bag. 44

coul dresult in serious injuries in the event
of an accident.
R Each occupant should wea rthei rseatb elt
at al ltimes ,because sea tbelts hel preduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front ai rbag,k nee bags, front-
passenger front ai rbag,sidei mpact air
bags, hea dairbags) ,Emergency Tension-
ing Device s(ETDs) and sea tbeltf orce lim-

the protection offered to properl ybelted
occupants in certai nfrontal (front ai rbags,
knee bags and ETDs) and sid e(side impact

which excee dpreset deployment thresh-
olds.
R Neve rwearthe shoulde rbeltu nde ryour
arm, across your neck or off your shoulder. In af rontal crash ,you rb odyw ould move
too far forward .Tha tw ould increase the
chance of hea dand neck injuries. The seat
