Occupant safety
50Make sure you do not route the belt across
luggage compartment cover
3.
X Swing back rear seat backrest 2until it
engages.
The red lock verification indicator is no lon-
ger visible (Y page 150). G
Risk of injury
Make sure that the rear seat backrest is
fully locked. The red lock verification indi-
cators on the left and right should no longer
be visible. If they are, the rear seat backr-
ests are not locked. If this is the case, occu-
pants could be injured in the event of an
accident, e.g. by objects being thrown for-
wards from the luggage compartment.
X Move head restraint 1back down again
slightly if necessary (Y page 66). Make
sure that you do not interfere with the cor-
rect routing of TopTether belt* 6.
X Install the ISOFIX child restraint system
with TopTether*. Comply with the manu-
facturer's installation instructions.
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 of age 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 22 kg, you must
also use a padded table* which has been spe-
cially approved for the integrated child seat
(Y page 51). 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 Do not modify the integrated child seat.
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 that has
been damaged or subjected 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.
Folding out the child seat 1
Release catch
