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.
X Tilt the top of the NECK-PRO head restraint
cushion forwards in the direction of arrow :.
X Push the NECK-PRO head restraint cushion
down as far as it will go in the direction of
arrow ;.
X Firmly push the NECK-PRO head restraint
cushion back in the direction of arrow =until
the cushion engages.
X Repeat this procedure for the second NECK-
PRO head restraint.
i Resetting the NECK-PRO head restraints
requires a lot of strength. If you have difficulty
resetting the NECK-PRO head restraints, have this work carried out at a qualified specialist
workshop. PRE-SAFE
®
(anticipatory occupant
protection)
Introduction In certain hazardous situations, PRE-SAFE
®
takes pre-emptive measures to protect the vehi- cle occupants. Important safety notes !
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.
Although your vehicle is equipped with PRE-
SAFE ®
, the possibility of injury in the event of an
accident cannot be ruled out. Always adapt your
driving style to suit the prevailing road and
weather conditions and maintain a safe distance from the vehicle in front. Drive carefully.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated
R in critical driving situations, e.g. when physi-
cal limits are exceeded and the vehicle under- steers or oversteers severely
R on vehicles with the Driving Assistance pack-
age: if BAS PLUS intervenes powerfully or the
radar sensor system detects an imminent
danger of collision in certain situations
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detected:
R the front seat belts are pre-tensioned
R if the vehicle skids, the front side windows
and the panorama sliding sunroof are closed
R vehicles with the memory function: the front-
passenger seat is adjusted if it is in an unfav-
ourable position
R vehicles with a multicontour seat: the air pres-
sure in the side bolsters of the backrest is
increased
If the hazardous situation passes without result- ing in an accident, PRE-SAFE ®
slackens the belt
pre-tensioning. On vehicles with multicontour
seats, the air pressure in the side bolsters is
reduced again. All settings made by PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back slightly
when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. Informa-
tion about the convenience function can be
found under "Belt adjustment" (Y page 40).46

WARNING
If you close a side window again immediately after it has been blocked or reset, the side window
closes with increased or maximum force. The reversing function is then not active. Parts of the

Make sure that no parts of the body are in the closing area. To stop the closing process, releasethe switch or push the switch again to reopen the side window. Problem
Possible causes/consequences and
M MSolutions A side window cannot be
closed because it is
blocked by objects, e.g.
leaves in the window
guide. X

X Close the side window. A side window cannot be
closed and you cannot
see the cause. If a side window is obstructed during closing and reopens again
slightly:
X Immediately after the window blocks, pull the corresponding switch
again until the side window has closed.
The side window is closed with increased force.
If a side window is obstructed again during closing and reopens again slightly:

Important safety notes
In this section, the term "sliding sunroof" refers to the panorama sliding sunroof. G

with you and lock the vehicle. Never leave
children unattended in the vehicle.
! Only open the panorama sliding sunroof if it
is free of snow and ice. Otherwise, malfunc-
tions may occur.

tuations in the vehicle interior. Change the posi-
tion of the sliding sunroof or open a side window slightly to reduce or eliminate these noises. Panorama sliding sunroof reversing
function
In this section, the term "sliding sunroof" refers to the panorama sliding sunroof.
The sliding sunroof is equipped with an auto-
matic reversing feature. If an object blocks or
restricts the sliding sunroof during the closing
process, the sliding sunroof opens again auto-
matically. The automatic reversing feature is,
however, only an aid and is no substitute for your
attention when closing the sliding roof. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 4 mm of the closing movement
R during resetting
R when closing the sliding sunroof again man-
ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
When closing make sure that no body parts
are in the closing area.
If someone is trapped:
R release the switch immediately or
R press the switch in any direction during the
