WARNING
Modifications to or work performe dincor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, beltt en-
sioners, belt forc elimiters and airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an acciden tdespite
the deceleration forc ebeing sufficien ttotrig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tamper with elec-
tronic components or their software. SRS (Supplemental Restraint System)
Introduction SRS consist
sof:
R the 6 SRS warning lamp
R airbags
R airbag control unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS reduces the risk of occupant scoming
into contact with the vehicle's interior in the
event of an accident .Itcan also reduce the
effect of the forces to which occupant sare
subjected during an accident.
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 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than afew seconds
after the engine is started. G
WARNING
If SRS is malfunctioning, individual systems
may be activated unintentionally or may not
be triggered in the event of an accident with
ah igh rate of vehicle deceleration.
Am alfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignition is switched on.
R the engine is runnin gand the 6SRS
warning lamp does not go out after afew
seconds.
R the engine is runnin gand the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at aq ualified specialist workshop. Mercedes-
Benz recommends that you use aMercedes-
Benz Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
aq ualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of
acollision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
i The belt tensioners can only be triggered
if the seat belt tongues are correctly
engaged in the seat belt buckles.
If there is an even higher rate of vehicle decel-
eration or acceleration in alongitudinal direc-
tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of ac ollision. In the first deployment stage, Occupant safety

When the roll bars are extended, the rear
head restraints also extend automatically.
Oncet he roll bars are extended, you can no
longer lower the rear head restraints. The soft
top can no longer be operated. In this case,
visit the nearest qualified specialist work-
shop. G
WARNING
If the roll bar is malfunctioning, the A
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. PRE-SAFE
®
(preventative occupant
protection)
PRE-SAFE ®
takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes:
R in emergency braking situations, e.g. if BAS
is activated or for vehicles with DISTRONIC
PLUS, BAS PLUS intervenes powerfully
R if the radar sensor system detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R in critical driving situations, e.g. when phys-
ical limits are exceed and the vehicle under-
steers or oversteers severely
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R vehicles with the memory function: it
adjusts the front-passenger seat if it is in
an unfavourable position. R
vehicles with amulticontour seat: the air
pressure in the seat side cushions and in
the backrest side bolsters is increased.
R if the vehicle skids, the front side windows
and, on the Coupé,t he panorama sliding
sunroof, are closed so that only asmall 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.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensionin gisreduced and the
locking mechanism is released. G
WARNING
When adjusting the seat, make sure that
nobody can become trapped.
! Make sure that there are no objectsint he
footwell or behind the seats when moving
the seat back. There is arisk that the seats
and/or the objectsc ould be damaged.
More information about seat-belt adjust-
ment, aconvenience function integrated into
PRE-SAFE ®
,c an be found in the "Seat-belt
adjustment" section (Y page 49). NECK-PRO head restraints
The NECK-PRO head restraints increase pro-
tection to the driver's and front passenger's
head and neck.Tot his end, the NECK-PRO
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. This provides better head

4 is not lit.
To make you aware of this danger, acorre-
sponding warning sticker has been affixed on
the dashboard and on both sides of the sun
visor on the front-passenger side.
