Operation
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 trig-
gered in an accident, you must reset the NECK-
PRO head restraints on the driver's and front-
passenger seat (Y page 53). Otherwise, the
additional protection will not be available in the event of another rear-end collision. You can rec-ognise when NECK-PRO head restraints have
been triggered by the fact that they have moved
forwards and can no longer be adjusted.
Mercedes-Benz recommends that you have the
NECK-PRO head restraints checked for func-
tionality at a qualified specialist workshop after a rear-end collision.
Resetting triggered NECK-PRO head
restraints Do not place your fingers between the uphols-
tery of the head restraint and the seat. Pay par-
ticular attention while resetting the NECK-PRO
head restraints.

this work carried out at a qualified specialist
workshop. PRE-SAFE
®
(anticipatory occupant
protection)
PRE-SAFE ®
informs you of certain critical driving
situations and takes pre-emptive measures to
protect the vehicle occupants.
PRE-SAFE ®
can take the following measures
independently of each other:
R pre-tensioning the driver's and front-
passenger seatbelt.
R closing the side windows.
R setting a more favourable seat position for the
front-passenger seat.
R vehicles with a multicontour seat: increasing
the air pressure in the side bolsters of the seat
backrest.
! Make sure that there are no objects in the
footwell or behind the seats. There is a risk
that the seats and/or the objects could be
damaged when PRE-SAFE ®
is activated.
Should an accident not occur, the preventative
measures taken are cancelled. Certain settings
must be made yourself. X If the seat belt pre-tensioning is not reduced,
move the seat backrest back slightly.
Seat belt pre-tensioning is released. PRE-SAFE
