79 Safety and Security
Occupant safety
More information can be found in the
“Practical hints” section (
page 360).Installation of infant and child restraint
systems
This vehicle is equipped with tether an-
chorages for a top tether strap at each of
the rear seating positions.
1Anchorage ring
2Hook
Open the trunk and release the rear
seat backrest (
page 268).
Fold rear seat backrest slightly for-
ward.
Guide top tether strap between head
restraint and top of seat back.
Head restraint must be installed and
positioned such that the top tether
strap can pass freely between the head
restraint and the top of seat back.
Make sure the tether strap is not twist-
ed.
1Anchorage ring
2Hook
Fold up anchorage ring1.
Securely fasten hook2, which is part
of the tether strap, to anchorage
ring1.
Warning!
G
If the 56 indicator lamp should not
illuminate, the system is not functioning.
You must see an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.Warning!
G
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the Occupant Classifi-
cation System. The bottom of the child seat
must make full contact with the passenger
seat cushion. An incorrectly mounted child
seat could cause injuries to the child in case
of an accident, instead of increasing protec-
tion for the child.
Follow the manufacturer’s instructions for
installation of child seats.
