in the event of an accident. Appropriate seat
covers can be obtained from a Mercedes-
Benz Service Centre.
The purpose of pelvisbag deployment is to
enhance the level of protection of the vehicle
occupants on the side of the vehicle on which
the impact occurs. The pelvisbags
:deploy next to and below
the outer seat cushions. They are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
R independently of the seat belt use
R independently of the front airbags
R independently of the belt tensioners
R if the vehicle overturns, but only if the sys-
tem detects high vehicle deceleration in a
lateral direction and determines that side-
bag deployment can offer additional pro-
tection to that provided by the seat belt
Windowbags
The purpose of the windowbags is to enhance
the level of protection for the head (but not
chest or arms) of the vehicle occupants on
the side of the vehicle on which the impact
occurs.
The windowbags are integrated into the side
of the roof frame and run from the front door
(A-pillar) to the rear door (C-pillar). Example: Saloon

PRE-SAFE
®
may take the following measures
in these situations:
R it tensions the front seat belts.
R on vehicles with memory functions*: it
adjusts the front-passenger seat if this is in
an unfavourable position.
R on vehicles with multicontour seat* or
active multicontour seat*: it increases the
air pressure in the seat side cushions and
the backrest side cushions.
R if the vehicle skids, it closes the sliding/
tilting sunroof* or panorama sliding sun-
roof* and the side windows so that only a
small gap remains.
if the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning. You can then reverse
all settings made by PRE-SAFE ®
. On vehicles
with a multi-contour seat* or an active multi-
contour seat*, the air pressure in the side
bolsters is then reduced again.
If the seat belts are not released:
X Move the backrest or the seat back slightly
until the belt tension is reduced.
The locking mechanism releases. G
Risk of injury
When adjusting the seat, make sure that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when adjusting
the seats. You could otherwise damage the
seats and the objects. NECK-PRO head restraints
NECK-PRO head restraints are designed to
increase protection to the driver's and front-
passenger's head and neck. To this end, the
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 when viewed in the direc- tion of travel. This provides better head sup-
port. G
Risk of injury
Head restraint covers prevent the NECK-PRO
head restraints from triggering correctly. Con-
sequently, the NECK-PRO head restraints
cannot provide the intended level of protec-
tion. Do not use head restraint covers.
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and front-passenger
seats (Y page 303). Head restraints that have
been triggered are tilted forwards. Children in the vehicle
If a child is travelling in your vehicle, secure
the child using a child restraint system which
is appropriate to the size and age of the child
and is recommended for Mercedes-Benz
vehicles. You should fit the restraint system
to a suitable rear seat. You can also secure
the child on the integrated child seat*
(Y page 53). Ensure that the child is secured
throughout the trip.
You can obtain information about the correct
child restraint system from any Mercedes-
Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems.
Information about this can be obtained
from any Mercedes-Benz Service Centre. G
Risk of injury
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. Children could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys-
tem could heat up and the child could burn
herself/himself on them. Occupant safety

Risk of injury
If the padded table and the side head
restraints are not secured in the vehicle as
specified, they may come loose. In the event
of an accident, sudden braking or abrupt
change in direction, they could injure vehicle
occupants or cause damage to the vehicle.
Secure the padded table in the vehicle as
specified.
On vehicles with TIREFIT kit, the side head
restraints can be stored in the stowage com-
partment under the boot/luggage compart-
ment floor (Y page 204)/(Y page 204).
Child-proof locks If children are travelling in the vehicle, you can
activate the child-proof locks for the rear
doors.
Child-proof locks for the rear doors
The child-proof locks on the rear doors enable
you to secure each door individually. A locked
door cannot be opened from the inside. The
door can be opened from the outside if the
vehicle is unlocked. G
Risk of accident and injury
Activate the child-proof locks for the rear
doors and the override switch for the rear
windows if children are travelling in the vehi-
cle. Otherwise, the children could open doors
or windows while the vehicle is in motion and
injure themselves or others. Example: Saloon
