NECK-PRO head restraint/NECK-PRO
luxury head restraints
Important safety notes G
WARNING
The function of the head restraint may be
impaired if you:
R attach objects such as coat hangers to the
head restraints, for example
R use unsuitable head restraint covers
If you do so, the head restraints cannot fulfil
their intended protective function in the event of an accident. In addition, objects attached
to the head restraints could endanger other
vehicle occupants. This poses an increased
risk of injury.
Do not attach any objects to the head
restraints and only use suitable head restraint
covers.
Consult a Mercedes-Benz Service Centre
regarding the availability of suitable seat or
head restraint covers.
Operation NECK-PRO head restraints/NECK-PRO luxury
head restraints offer additional protection
against head and chest injuries. In the event
of a rear collision of a certain severity, the
NECK-PRO head restraints/NECK-PRO luxury
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards. This provides better head support.
If the NECK-PRO head restraints/NECK-PRO
luxury head restraints have been triggered in
an accident, reset the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver's and front-passenger seats
(Y page 54). Otherwise, the additional pro-
tection will not be available in the event of
another rear-end collision. NECK-PRO head
restraints/NECK-PRO luxury head restraints
that have been triggered are moved forwards and can no longer be adjusted. Mercedes-Benz recommends that you have
the functionality of the NECK-PRO head
restraints/NECK-PRO luxury head restraints
checked at a qualified specialist workshop
after a rear-end collision.

®
(anticipatory occupant
protection)
Introduction In certain hazardous situations, PRE-SAFE
®
takes pre-emptive measures to protect the
vehicle 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 phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
R on vehicles with DISTRONIC PLUS: if BAS
PLUS brakes hard or the radar sensor sys-
tem detects an imminent danger of colli-
sion in certain situations
PRE-SAFE ®
takes the following measures
depending on the hazardous situation detec-
ted:
R the front seat belts are pre-tensioned.
R if the vehicle skids, the sliding sunroof and
the side windows are closed so that only a small gap remains. 54
Occupant safetySafety
R
vehicles with the memory function: the
front-passenger seat is adjusted if it is in an unfavourable position.
R Vehicles with a multicontour seat or active
multicontour seat: the air pressure in the
side bolsters of the backrest is increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. On vehicles with mul-
ticontour seats/active 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. Fur-
ther information can be found under "Belt
adjustment" (Y page 47). Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
R the hazard warning lamps are activated
R the emergency lighting is activated
R the vehicle doors are unlocked
R the front side windows are lowered
R the electrically adjustable steering wheel is
raised
R the engine is switched off
R vehicles with the Mercedes-Benz emer-
gency call system: automatic emergency
call Children in the vehicle
Important safety notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat. Children are generally better pro-
tected there.
If a child younger than 12 years old and under
1.50 m in height is travelling in the vehicle:
R always secure the child in a child restraint
system suitable for Mercedes-Benz vehi-
cles. The child restraint system must be
appropriate to the age, weight and size of
the child.
R be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there is a risk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle. Children in the vehicle

It is advisable to use Mercedes-Benz care
products to clean child restraint systems
recommended by Mercedes-Benz. You can obtain information about this at any
Mercedes-Benz Service Centre. ISOFIX child seat securing system
G
WARNING
ISOFIX child restraint systems do not offer
sufficient protective effect for children whose weight is greater than 22 kg who are securedusing the safety belt integrated in the child
restraint system. The child could, for example, not be restrained correctly in the event of an
accident. This poses an increased risk of
injury or even fatal injury.
If the child weighs more than 22 kg, only use
ISOFIX child restraint systems with which the child is also secured with the vehicle seat belt. Also secure the child restraint system with the
Top Tether belt, if available.
When fitting a child restraint system, be sure to observe the manufacturer's installation
instructions and the instructions for correct
use of the child restraint system
(Y page 63).
Before every trip, make sure that the ISOFIX
child restraint system is engaged correctly in both ISOFIX securing rings.
! When fitting the child restraint system,
make sure that the seat belt for the centre
seat does not get trapped. Otherwise, the
seat belt could be damaged. Example: Coupé
When installing the ISOFIX child restraint sys- tem, fold protective caps ;of securing
rings :inwards.
X Install the ISOFIX child restraint system on
both ISOFIX securing rings :.
ISOFIX is a standardised securing system for specially designed child restraint systems on
the rear seats. ISOFIX securing rings :for
two ISOFIX child restraint systems are fitted
on the left and right of the rear seats.
Secure child restraint systems without an
ISOFIX child seat securing system using the
seat belts in the vehicle. When fitting a child
restraint system, be sure to observe the man-
ufacturer's installation instructions and the
instructions for correct use of the child
restraint system (Y page 63). Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured
with ISOFIX and the vehicle. It helps reduce
the risk of injury even further. If the child
restraint system is fitted with a Top Tether
belt, this should always be used.

Child restraint system on the front-
passenger seat
General notes Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat.
Vehicles with automatic child seat recogni-
tion on the front-passenger seat: if it is abso- lutely necessary to fit a child restraint systemto the front-passenger seat, always observe
the information on the "Automatic child seat
recognition on the front-passenger seat"
(Y page 59).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the automatic child seat recognition
sensor system
R the unintentional disabling of the front-
passenger front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the
front-passenger sun visor, see the illustra-
tion. G
WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is off, the front-passenger front airbag can
deploy in the event of an accident. The child
could be struck by the airbag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air-
bag has been disabled. The PASSENGER AIR-
BAG OFF indicator lamp must be lit.
NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it, DEATH or SERIOUS INJURY to the
CHILD can occur.
Vehicles without automatic child seat
recognition on the front-passenger seat If the front-passenger seat of your vehicle is
not equipped with automatic child seat rec-
ognition, this is indicated by a special sticker. The sticker is affixed to the side of the dash-
board on the front-passenger side. The
sticker is visible when you open the front-
passenger door.
If you turn the key to position 2in the ignition
lock, the PASSENGER AIR BAG OFF indicator lamp lights up briefly. It has no function, how-ever, and does not indicate that the front-
passenger seat is equipped with automatic
child seat recognition.
In this case, always fit the rearward-facing
child restraint system to a suitable rear seat
(Y page 63).
Observe the following information under
"Rearward-facing child restraint system" and
"Forward-facing child restraint system" as
well as information on the suitable position- Children in the vehicle

Move the belt height adjustment to the low-
est position.
X Move the backrest to an almost vertical
position.
The bottom and back of a forward-facing
child restraint system must make full con-
tact with the front-passenger seat cushion
and backrest. The child restraint system
must not touch the roof. Adjust the back-
rest angle accordingly. Also observe the
child restraint system manufacturer's
installation instructions.
