Securing a Top Tether
& WARNING Risk of injury or death if the
rear seat backrests are not locked after
installing Top Tether belts
The rear seat backrests may fold forwards
when driving.
In this case, child restraint systems may no
longer perform their intended protective
function. Additional injuries may also be
caused.
#
Always lock rear seat backrests after
installing Top Tether belts.
#
Pay attention to the lock verification
indicator.
Ensure that the rear seat backrest is engaged. To
do so, pull forcefully on the seat backrest.
¯ If the child restraint system is equipped
with a Top Tether belt:
The risk of injury can be reduced by a Top
Tether. The Top Tether belt enables an
additional connection between the child
restraint system attached with LATCH-
type (ISOFIX) and the vehicle.
The Top Tether anchorages for the second row of
seats are located on the back of the seat back‐
rest. For the third row of seats, use the Top
Tether anchorage on the back of the seat back‐
rest.

lation instructions.

restraint 1 between the two head restraint
bars.
