55dent. This can result in serious or even fatal
injury to the secured child in the event of
an accident, heavy braking or a sudden
change in direction.
For this reason, have child restraint sys-
tems and their anchorages which are dam-
aged or which have been subjected to a
load in an accident checked immediately at
a qualified specialist workshop.
! When fitting the child restraint system,
make sure that the seat belt for the middle
seat does not become trapped. It could
otherwise be damaged. 1
Securing rings Integrated child seat* The child seats are integrated into the right
and left-hand sides of the seats of the rear
bench seat. They comply with the legal
requirements of ECE Regulation 44.03.
Mercedes-Benz recommends the integrated
child seat for children from approximately
two to twelve years or with a body weight of
12.5 kg to 36 kg.
For children between approximately two and
four years of age or weighing between
approximately 12.5 kg and 18 kg, you must
also use a padded table which has been spe-
cially approved for the integrated child seat.
G
Risk of injury
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R You must follow the manufacturer's
installation instructions for the child seat
when fitting the padded table and fas-
tening the seat belt.
R Do not modify the integrated child seat
or padded table.
R When the child seat is occupied, adjust
the head restraint to a position at which
the back of the child's head is supported by the centre of the head restraint at
about eye level.
R Replace an integrated child seat or pad-
ded table that has been damaged or sub-
jected to a heavy load as the result of an
accident
R Be aware that children under two years
of age require a different child restraint
system. Information about other child
restraint systems is available from any
Mercedes-Benz Service Centre.
R The rear seat backrest in the vehicle
must be securely locked in position. 1

Risk of injury
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R The shoulder belt section of the seat belt
must be routed across the middle of the
child's shoulder – never across the
child's neck – and be pulled tight against
the child's chest. The lap section of the
seat belt must be routed across the
child's pelvis – not across the abdomen
– and be pulled tight against the child's
body; retighten the belt strap if neces-
sary.
R Never secure more than one child at a
time in the child restraint system.
R The belt must be routed through the
hook.
R The belt strap must not be trapped or
twisted, nor rub against any sharp edges. Also observe the assembly instructions for
the padded table and the additional warn-
ings and information about risk of injury.
X Pull the belt smoothly from the belt reel.
X Guide the lower lap section of the belt
through hook 2.
X Engage the belt tongue in the buckle.
X If the integrated child seat is being used
without the padded table, make sure that
the belt:
R is routed as low as possible across the pel-
vic area, in front of the hips
R is tightened across the lap by pulling
upwards on the child's shoulder belt
R is tight and is routed across the middle of
the child's shoulder
R is not twisted and does not pass across the
child's neck or under the child's arm

The optional equipment supplied with your
vehicle includes two KEYLESS GO keys. KEY-
LESS GO allows you to lock/unlock and start
the vehicle simply by carrying the KEYLESS
GO key with you. When you touch the surface
of the sensors on the vehicle's door handles,
KEYLESS GO establishes a radio connection
between the vehicle and the key.
When you touch the inner surface of the door
handle or press the button on the tailgate
handle (Estate), your vehicle unlocks cen-
trally if the factory settings have not been
changed:
R the doors
R the boot lid/tailgate
R the fuel filler flap
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid
KEYLESS GO key is in the vehicle by periodi-
cally establishing radio contact. G
Risk of accident
If children are left unsupervised in the vehi-
cle, they could open a door from the inside,
even if it has been locked. Or they could
start the vehicle if a valid KEYLESS GO key is in the vehicle and they press the KEY-
LESS GO button on the gear selector lever.
They could endanger themselves and oth-
ers. Never leave children unsupervised in
the vehicle. Switch off the engine and take
the KEYLESS GO key with you, even if you
are only leaving the vehicle for a short time. 1
