R Cabriolet: if the vehicle skids, it closes the
front side windows so that only asmall gap
remains.
if the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. You can then reverse
all settings made by PRE-SAFE ®
.Onv ehicles
with amulticontour seat*, the air pressure in
the side bolsters is reduced.
If the seat belts are not released:
X Move the backrest or the seat back slightly
until the belt tension is reduced.
The locking mechanism releases. G
Risk of injury
When adjusting the seat, make sure that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when adjusting
the seats. You could otherwise damage the
seats and the objects. Roll bar (Cabriolet)
The roll bars are located under the rear head
restraints. They are extended if systems
detect that the vehicle is in danger of over-
turning. G
Risk of injury
Make sure the roll bars and head restraints
can move freely in order to prevent injuries
when the roll bars extend.
When the roll bars are extended, the rear
head restraints also extend automatically.
Once the roll bars are extended, you can no
longer lower the rear head restraints or oper-
ate the soft top. In this case, visit the nearest
qualified specialist workshop. G
Risk of injury
If the roll bar is malfunctioning, the 0073
Malfunction Consult workshop message
appears in the multifunction display. The roll
bars will then not be extended in the event of
an accident. This could result in severe or
even fatal injuries to you and other occupants.
In this case, visit aqualified specialist work-
shop immediately and have the roll bar
checked. NECK-PRO head restraints
NECK-PRO head restraints are designed to
increase protection to the driver's and front-
passenger's head and neck.Tot his end, the
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards in the event of arear-end collision of
ac ertain severity when viewed in the direc-
tion of travel. This provides better head sup-
port. G
Risk of injury
Head restraint covers prevent the NECK-PRO
head restraints from triggering correctly. Con-
sequently, the NECK-PRO head restraints
cannot provide the intended level of protec-
tion. Do not use head restraint covers.
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and front-passenger
seats (Y page 257). Head restraints that have
been triggered are tilted forwards. Children in the vehicle
If ac hild is travelling in your vehicle, secure
the child using achild restraint system which
is appropriate to the size and age of the child
and is recommended for Mercedes-Benz
vehicles. You should fit the restraint system
to as uitabler ear seat. Ensure that the child
is secured throughout the trip. Occupant safety

the warning tone ceases as soon as the driver
and front passenger have fastened their seat
belts.
For certain countries only: regardless of
whether the driver or the front passenger
already have their seat belt fastened, the
0082 seat belt warning lamp lights up for six
seconds after the engine has been started. It
then goes out if both the driver and the front
passenger have fastened their seat belt. i

belt warning lamp (Y page 236). Rear seat belt status indicator
The rear-compartment seat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened. It indicates the rear
seat on which the belt is fastened.
