Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Please read the information on qualified
specialist workshops (Y page 22).Occupant safety
Introduction
In this section, you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint system consists of:
R seat belts
R child restraint systems
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R air bag system components with:
-PASSENGER AIR BAG OFF indicator lamp
- front-passenger seat with Occupant
Classification System (OCS)
The different air bag systems work
independently of each other. The protective
functions of the system work in conjunction
with each other. Not all air bags are deployed
in an accident. G
WARNING
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See "Children in the vehicle"
(Y page 51) for more information on
infants and children traveling with you in
the vehicle and restraints for infants and
children. SRS (Supplemental Restraint System)
Introduction SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS consists of:
R
0075 SRS warning lamp
R air bags
R air bag control unit (with crash sensors)
R Emergency Tensioning Devices
R seat belt force limiters
SRS warning lamp SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The
0075 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started. 36
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

system. This confirmation can also be found
in the installation instructions that are
included with the child restraint system.
When using any infant restraint, child
restraint or booster seat, make sure to
carefully read and follow all manufacturer's
instructions for installation and use.
Please read the warning labels affixed to the
interior of the vehicle or to the infant restraint
or child restraints. G
WARNING
Children under 12 years must be secured
correctly in a suitable infant or child restraint
system or booster seat suitable for the size
and weight of the child.
The infant or child restraint system must be
correctly secured using the vehicle's seat belt
in complete accordance with the child seat
manufacturer's instructions.
Occupants, in particular children, must sit as
upright as possible, fasten the seat belt
correctly and use a suitable infant restraint
system, child restraint system or booster seat
suitable for the size and weight of the child.
Children can be killed or seriously injured by
an inflating air bag. Please observe the
following important information:
R your vehicle is equipped with air bag
technology designed to deactivate the
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the passenger seat.
R a child in a rear-facing child restraint on the
passenger seat will be seriously injured or
even killed if the passenger front air bag
inflates in a collision which could occur
under some circumstances, even with the
air bag technology installed in your vehicle.
R if you install a rearward-facing child
restraint system on the front-passenger
seat, make sure the 00730074indicator
lamp is illuminated, indicating that the
front-passenger front air bag is disabled. If the
00730074 indicator lamp does not light
up or goes out when the child restraint
system is installed, check the anchorages
of the restraint system. Check the
00730074 indicator lamp regularly while
driving to ensure that the 00730074
indicator lamp is illuminated. If the
00730074 indicator lamp goes out or
remains out, you may only carry a child on
the front-passenger seat once the system
has been repaired.
a child in a rear-facing child restraint on the
passenger seat will be seriously injured or
even killed if the passenger front air bag
inflates.
R when securing a child in a child restraint
system on the front-passenger seat, you
must:
- move the front-passenger seat as far
back as possible
- use a child restraint system that is
suitable for the age, size and weight of
the child
- observe the manufacturer's installation
instructions in order to install and secure
the child restraint system correctly.
R for children larger than the typical 12-
month-old child, the passenger front air bag
may or may not be activated. G
WARNING
Infants and small children should never share
a seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.
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.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Position
the shoulder belt across the chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) until 52
