GWARNING
The function of the head restraint may be
impaired if you:
Rattach objects such as coat hangers to the
head restraints, for example
Ruse head restraint covers
If you do so, the head restraintscannot fulfill
their intended protective function in the event
of an accident. In addition, objects attached
to the head restraintscould endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any objects to the head
restraintsand do not use head restraint
covers.
NECK-PRO head restraints/NECK-PRO luxury
head restraintsincrease protection of the
driver'sand front-passenger's head and
neck. In the event ofarear collision of a
certain severity, the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver'sand the front-passenger seats
are moved forwards and upwards. This
provides better head support.
If the NECK-PRO head restraints/NECK-PRO
luxury head restraintshave been triggered in
an accident, reset the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver'sand front-passenger seats
(Ypage 54). Otherwise, the additional
protection 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

Child restraint systems
Important safety notes
GWARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommendthat
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint,toddler restraint,orbooster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint,toddler restraint,orbooster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to placeachild in the front
passenger seat:
RYour vehicle is equipped with air bag
technology designed to deactivate the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight ofastandard appropriate
child restraint on the front passenger seat.
RFor children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be activated.
Always make sure theindicator
lamp is illuminated, indicatingthat the front
passenger front air bag is deactivated.
RAchild inarear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates inacollision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
placeachild inarear-facing child restraint
in the front seat. We therefore strongly
recommendthat you always placeachild
inarear-facing child restraint inabackseat.
RIf you must installarear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure theindicator
lamp is illuminated, indicatingthat the front
passenger front air bag is deactivated.
Should theindicator lamp not
illuminateorgoout while the restraint is
installed, please checkinstallation.
Periodically check theindicator
lamp while drivingtomake sure the
indicator lamp is illuminated. If the
indicator lamp goes out or
remainsout, do not transportachild on the

front passenger seatuntil the system has
been repaired.
Achild inarear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
RIf you have to placeachild inaforward-
facing child restraint on the front passenger
seat, move the seat as far back as possible,
use the proper child restraint
recommended for the age, size and weight
of the child, and secure child restraint with
the vehicle's seat belt according to the
child seat manufacturer's instructions.
GWARNING
If the child restraint system is installed
incorrectly onasuitable seat, it cannot
protect as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There
is an increased risk of injury, possibly even
fatal.
Make sure that you observe the child restraint
system manufacturer's installation
instructions and the notes on use. Please
ensure, that the base of the child restraint
system is always resting completely on the
seat cushion. Never place objects, e.g.
cushions, under or behind the child restraint
system. Only use child restraint systems with
the original cover designed for them. Only
replace damaged covers with genuine covers.

If the child restraint system is installed
incorrectly or is not secured, it can come
loose in the event of an accident, heavy
braking orasudden change in direction. The
child restraint system could be thrown about,
strikingvehicle occupants. There is an
increased risk of injury, possibly even fatal.
Always install child restraint systems
properly, even if they are not being used.
Make sure that you observe the child restraint
system manufacturer's installation
instructions.
GWARNING
Child restraint systems or their securing
systems which have been damaged or
subjected toaload in an accident can no
longer protect as intended. The child cannot
then be restrained in the event of an accident,
heavy braking or sudden changes of direction.
There is an increased risk of injury, possibly
even fatal.
Replace child restraint systems which have
been damaged or subjected toaload in an
accident as soon as possible. Have the
securing systems on the child restraint
system checked ataqualified specialist
workshop, before you installachild restraint
system again.
GWARNING
Infantsand small children should never share
aseat belt with another occupant. In the event
of an accident, they could be crushed
between the occupant and seat belt.
Achild's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children that are too large forachild restraint
must travel in seats using normal seat belts.
