the system determines that the front-
passenger seat is occupied. The 4
PASSENGER AIRBAG OFF indicator lamp on
the centre console is not lit (Y page 53).
This means that achild restraint system with-
out automatic child seat recognition has been
fitted or that achild restraint system with
automatic child seat recognition is incorrectly
fitted.
! Do not place heavy objectsont he front-
passenger seat. The system may then
detect that the seat is occupied and if there
is an accident, the restraint systems on the
front-passenger side could be deployed.
Have restraint systems that have been trig-
gered replaced.

WARNING
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Benz vehicles.
The seat covers must have aspecial tear seam
for sidebags/pelvisbags. Otherwise, the side-
bag/pelvisbag cannot deploy correctly and
would fail to provide the intended protection
in the event of an accident. Appropriate seat
covers can be obtained, for example, from a
Mercedes-Benz Service Centre.
When deployed, the sidebags offer additional
protection for the thorax of the vehicle occu-
pants on the side of the vehicle on which the
impact occurs. However, they do not protect
the:
R head
R neck
R arms Example: Coupé
Front sidebags
:and rear sidebags ;
deploy next to the outer seat cushions.
The sidebags are deployed:
R on the side on which an impact occurs
R at the start of an accident with ahigh rate
of lateral vehicle deceleration or accelera-
tion, e.g. in aside impact
R independently of seat belt use
R independently of the front airbags
R independently of the belt tensioners Cabriolet: if the vehicle overturns, the side-
bags are generally not deployed. They are

®
(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.

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

WARNING
Only use headr estraint covers which have
been tested and approved by Mercedes-Benz
for yourv ehicle model.
The use of non-approved head restraint cov-
ers may preven tNECK-PRO head restraints
from triggering properly. Consequently, the
NECK-PRO head restraints cannot provide the
intended level of protection.
Consult aMercedes-Benz Service Centre
regarding availability.
If the NECK-PRO head restraint shave been
triggered in an accident, reset the NECK-PRO
head restraint sonthe driver’s and front-
passenger seat (Y page 46). Otherwise, the
additional protection will not be available in
the event of another rear-en dcollision. You
can recognise when NECK-PRO head
restraint shave been triggered by the fact that
they have moved forwards and can no longer
be adjusted. Resetting triggered NECK-PRO head
restraints
Following arear-en dcollision, Mercedes-
Benz recommends that you have NECK-PRO
head restraint schecked at aqualified spe-
cialist workshop, e.g. aMercedes-Benz
Service Centre.
i Resetting the NECK-PRO head restraints
requires alot of strength. If you have diffi-
culty resetting the NECK-PRO head

X Repeat this procedure for the second
NECK-PRO head restraint. Seat belts
Important safety notes Seat belts are the most effective means of
restraining the movemen
tofvehicle occu-
pants in the event of an accident. This
reduces the risk of vehicle occupant scoming
into contact with parts of the vehicle interior. G
WARNING
As eat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot perform its intended
protective function .Under certain circum-
stances, this could cause severe or even fatal
injuries in the event of an accident.
Make sure that all occupant s–inparticular,
