TopTether
TopTether provides an additional connection
between the child restraint system secured
with ISOFIX and the rear seat. It helps reduce
the risk of injury even further.

the rear of the backrests:

G Risk of injury
Do not secure the TopTether hook* to the
loop underneath the TopTether anchorage
if you are securing a child restraint system
in the 3rd row of seats*. The child restraint
system is then not secure. An incorrectly
fitted child restraint system cannot perform
its intended protective function in the event
of an accident, and could even lead to inju-
ries.
