Roll bar (Cabriolet)
G
DANGER
If the roll bar is malfunctioning, the A
Malfunction Service Required message
appears in the multifunction display. The roll
bars 
will then possibly 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 a qualified
specialist workshop immediately and have
the roll bar checked. G
WARNING
Ensure that the area around the roll bars/rear
head restraints is kept clear. Otherwise,
someone could be injured by the roll bars
when they are triggered.
The roll bars are under the rear head
restraints. They are extended if systems
detect that the vehicle is in danger of
overturning.
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. The soft
top can no longer be closed. In this case, visit
the nearest qualified specialist workshop. NECK-PRO head restraints
Important safety notes G
WARNING
Do not secure any objects (e.g. coat hangers)
on 
 the NECK-PRO head restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide. G
WARNING
Seat or head restraint covers can cause a
malfunction when the NECK-PRO head
restraints are activated or when the side
impact air bags or pelvis air bags are deployed, or they can prevent this completely.
The 
NECK-PRO head restraints or side impact
air bags/pelvis air bags can therefore not
provide the intended protection. Do not use
any seat or head restraint covers. G
WARNING
For your protection, drive only with properly
positioned head restraints.
Adjust 
the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation. G
WARNING
For safety reasons, have the NECK-PRO head
restraints checked at a qualified specialist
workshop after a rear-end collision.
The NECK-PRO head restraints reduce the
likelihood of head and chest injuries. The
NECK-PRO 
head restraints on the driver's and
front-passenger seats are moved forwards
and upwards in the event of a rear-end
collision of a certain severity. This provides
better head support.
If the NECK-PRO head restraints have been
triggered in an accident, reset the NECK-PRO
head restraints on the driver’s and front-
passenger seat ( Y page 51). Otherwise, the
additional protection will not be available in
the event of another rear-end collision. You
can recognize when NECK-PRO head
restraints have been triggered by the fact that
they have moved forwards and can no longer
be adjusted.

®
 system G
WARNING
The PRE-SAFE ®
 
 system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRE-
SAFE ®
 system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions. G
WARNING
Make sure that nobody can become trapped
as you adjust the seat.
!  Make 
sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
PRE-SAFE ®
 takes preemptive measures to
protect occupants in certain hazardous
situations.
PRE-SAFE ®
 intervenes:
R if BAS intervenes, e.g. in emergency
braking situations
R if, on vehicles with DISTRONIC PLUS, BAS
PLUS intervenes powerfully
R if, on vehicles with DISTRONIC PLUS, the
radar sensor system detects an imminent
danger of collision in certain situations
R in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely
PRE-SAFE ®
 takes the following measures
depending on the hazardous situation
detected:
R the front seat belts are pre-tensioned.
R the front-passenger seat is adjusted if it is
in an unfavorable position.
R the air pressure in the side bolsters of the
seat cushion and seat backrest of the front
multicontour seats is increased.
R Coupe: if the vehicle skids, the panorama
roof with power tilt/sliding panel and the
front side windows are closed so that only
a small gap remains.
R Cabriolet: if the vehicle skids, the front side
windows are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
 slackens
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat is
reduced again. All settings made by PRE-
SAFE ®
 can then be reversed. 52

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, driver's side knee
bag, front-passenger front air bag, pelvis air
bags, side impact air bags, Coupe: window
curtain air bags for side windows, Cabriolet:
head bags), Emergency Tensioning Devices
(ETDs), seat belt force limiters, and front
seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver's side knee bag and ETDs) and side
(side impact air bags, pelvis air bags,
window curtain air bags, and ETDs) impacts
which exceed preset deployment
thresholds and in certain rollovers (window
curtain air bags and ETDs).
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. Never pass the shoulder
portion of the seat belt under your arm.
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. 54
