2013 MERCEDES-BENZ SLS AMG COUPE GT warning

G
WARNING
If the 00730074 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
00730074 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 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 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 00730074
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 00730074
indicator lamp is illuminated, the front-
passenger front air bag is deactivated. With
the 00730074 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 00730074 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
00730074 indicator lamp is illuminated,
the front-passenger front air 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 a preset 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 front passenger's weight category as
determined by the OCS
For further information, see "Air bag display
messages" (Y page 167). G
WARNING
Children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt fully in
accordance with the child seat
manufacturer's instructions.
Occupants, especially children, should always

technicians as soon as possible. Contact an
authorized Mercedes-Benz Center.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center.
In order to ensure proper operation of the air
bag system and OCS:
R Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R When seated, a passenger should not
position him/herself in such a way as to
cause the passenger's weight to be lifted
from the seat cushion as this may result in
the OCS being unable to correctly
approximate the passenger's weight
category.
R Read and observe all warnings in this
chapter.
System self-test The
00730074 indicator lamp illuminates
when you:
R turn the SmartKey to position 1or 2in the
ignition lock
R press the Start/Stop button once or twice
If an adult occupant is properly sitting on the
passenger seat and the OCS classifies the
occupant as an adult, the 00730074indicator
lamp illuminates and goes out again after
approximately 6 seconds.
If the seat is not occupied and the OCS
classifies the front passenger seat as being
unoccupied, the 00730074indicator lamp
will illuminate and not go out. G
WARNING
If the 00730074indicator lamp does not
illuminate, the system is not functioning. You
must contact an authorized Mercedes-Benz
Center before seating any child on the
passenger seat.
For more information, see "Problems with the
Occupant Classification System"
(Y page 46). G
WARNING
Never place anything between seat cushion
and child seat (e.g. a pillow), since it reduces
the effectiveness of the OCS. The underside
and rear side child restraint system must be
placed entirely on the seat cushion and the
backrest of the front-passenger seat
backrest.
If necessary, adjust the tilt of the passenger
seat backrest.
An incorrectly mounted child seat could cause
injuries to the child in case of an accident,
instead of increasing protection for the child.

Occupant safetySafety

Exiting in an emergency (Coupe only)
If the vehicle is lying on its roof after an
accident, the hinge fasteners of the gullwing
doors are released pyrotechnically. You will
hear a bang if this is the case. After the
fasteners have been released, the doors are
forced outwards. Simultaneously, the door
locks are unlocked. The 0075SRS warning
lamp lights up.
i The hinge fasteners are only released
when the control unit recognizes that
certain conditions have been fulfilled, e.g.
when the vehicle is in a stabilized position
on its roof.
The doors can then be moved from the
inside/outside by pulling the door handle. Seat belts
Important safety notes The use of infant or child restraints is required
by law in all 50 states, the District of
Columbia, the U.S. territories and all
Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened when the vehicle is in motion.
i See "Children in the vehicle"
(Y page 51) for further information on
infants and children traveling in the vehicle
as well as on child restraint systems. G
WARNING
Always fasten your seat belt before driving off.
Always make sure your passenger is properly
restrained. You and your passenger should
always wear seat belts.
Failure to wear and properly fasten and
position your seat belt considerably increases
your risk of injuries and their likely severity in
an accident.
If you are ever in an accident, your injuries
could be considerably more severe if you have
not fastened your seat belt correctly. If you do not fasten your seat belt, you are much more
likely to collide with parts of the vehicle
interior or be ejected from it. This may result
in serious or fatal injury.
In the same crash, the possibility of serious or
fatal injury is considerably reduced if you wear
your seat belt properly. The air bags can only
offer the intended protection if the occupants
are wearing their seat belts properly.
G
WARNING
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the seat belt is properly
positioned on the body. G
WARNING
Never let more people ride in the vehicle than
there are seat belts available. Make sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at a
time. G
WARNING
Damaged seat belts or seat belts that have
been subjected to stress in an accident must
be replaced and their anchoring points must
also be checked.
Only use seat belts which have been approved
by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to their failure to activate when
necessary.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection. Occupant safety

Correct use of the seat belts G
WARNING
USE SEAT BELTS PROPERLY
R Seat belts can only work when used
properly. Never wear seat belts in any other
way than as described in this section, as
that could result in serious injuries in the
event of an accident.
R Each occupant should wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, knee bags, front-
passenger front air bag, side impact air
bags, head air bags), Emergency
Tensioning Devices (ETDs) and seat belt
force limiters. The system is designed to
enhance the protection offered to properly
belted occupants in certain frontal (front air
bags, knee bags and ETDs) and side (side
impact air bags, head air bags and ETDs)
impacts which exceed preset deployment
thresholds.
R Never wear the shoulder belt under your
arm, across your neck or off your shoulder.
In a frontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder (it should not
touch the neck).
R Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your abdomen, it could cause serious injuries in
a crash.
R Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
R Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
R Never use a seat belt for more than one
person at a time. Do not fasten a seat belt
around a person and another person or
other objects at the same time.
R Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distribute impact forces.
The twisted seat belt against your body
could cause injuries.
R Pregnant women should also always use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
R Place the seat backrest in a position that is
as upright as possible.
R Check your seat belt during travel to make
sure it is properly positioned.
R Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R When using a seat belt to secure infant
restraints, toddler restraints, or children in
booster seats, always follow the child seat
manufacturer's instructions. G
WARNING
Do not pass seat belts over sharp edges. They
could tear.
Do not allow the seat belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the seat belt.
Never attempt to make modifications to seat
belts. This could impair the effectiveness of
the seat belts. 48

seated and properly secured in an
appropriately sized infant restraint, child
restraint system, or booster seat
recommended for the size and weight of the
child. For additional information, see the
"Children in the vehicle" section.
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint. Example: Coupe

Releasing seat belts X
Press release button 0085(Ypage 49) and
guide belt tongue 0044(Ypage 49) back
towards belt sash guide 0043(Ypage 49).
! Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt.
Damaged seat belts can no longer fulfill
their protective function and must be
replaced. Consult an authorized Mercedes-
Benz Center.
Belt warning for the driver and front
passenger Regardless of whether the driver's and front-
passenger seat belts have already been
fastened, the
0076seat belt warning lamp
lights up for six seconds each time the engine
is started. It then goes out once the driver and
the front passenger have fastened their seat
belts.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. The warning tone switches
off after approximately six seconds or once
the driver's seat belt is fastened. Occupant safety
49Safety Z

If after six seconds the driver or front
passenger have not fastened their seat belts
and the doors are closed:
R the 0076 seat belt warning lamp remains lit
as long as either the driver's or front-
passenger's seat belt is not fastened
R and if a vehicle speed of 15 mph
(25 km/h) is exceeded, the 0076seat belt
warning lamp lights up and a warning tone
also sounds with increasing intensity for a
maximum of 60 seconds or until the driver
or front-passenger seat belt has been
fastened
If the driver or front-passenger seat belt is
unfastened while the vehicle is in motion, the
0076 seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front-passenger seat belt has still not been
fastened after 60 seconds. The 0076seat belt
warning lamp stops flashing but remains lit.
After the vehicle comes to a standstill, the
warning tone is reactivated and the 0076seat
belt warning lamp flashes again if the vehicle
speed again exceeds 15 mph (25 km/h).
The 0076 seat belt warning lamp only goes
out if:
R both the driver and the front passenger
have fastened their seat belts.
or
R the vehicle is stationary and a door is open.
i For more information on the 0076seat
belt warning lamp, see "Warning and
indicator lamps in the instrument cluster,
seat belt" (Y page 187).
Emergency Tensioning Devices and belt
force limiters The seat belts are equipped with Emergency
Tensioning Devices and seat belt force
limiter.
!
If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the front- passenger seat. Otherwise, the Emergency
Tensioning Device could be triggered in the
event of an accident.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
When triggered, the seat belt force limiters
help to reduce the peak force exerted by the
seat belt on the vehicle occupant.
The seat belt force limiter are synchronized
with the front air bags, which take on a part
of the deceleration force. Thus, the force
exerted on the occupant is distributed over a
greater area.
When the ignition is switched on, the ETDs
cannot be triggered unless:
R the restraint systems are operational; see
"SRS warning lamp". (Y page 36)
R the belt tongue is engaged in the buckle on
each of the three-point seat belts.
R the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side.
The ETDs are triggered depending on the type
and severity of an accident:
R in the event of a head-on or rear-end
collision, if the vehicle decelerates or
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact
R in the event of a side impact, if the vehicle
is subjected to high lateral acceleration/
deceleration
R Coupe: in certain situations if the vehicle
rolls over, and the system determines that
it can provide additional protection
R Roadster: if the vehicle rolls over
If the Emergency Tensioning Devices (ETDs)
are triggered, you will hear a bang, and a small
amount of smoke may also be released. Only
in rare cases will the bang affect your hearing. 50
Occupant safetySafety

The smoke that is released generally does not
constitute a health hazard. The 0075SRS
warning lamp lights up. G
WARNING
Pyrotechnic ETDs that were activated must be
replaced.

SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts. G
WARNING
Do not carry heavy or hard objects in the
passenger compartment unless they are
firmly secured in place.
Unsecured or improperly positioned cargo
increases a child's risk of injury in the event
of:
R strong braking maneuvers
R sudden changes of direction
R an accident
If an infant or child is traveling in the vehicle:
X Secure the child with a child or infant seat
restraint system appropriate to the age and
weight of the child.
