Securing Top Tether
& WARNING Risk of injury or death if the
rear seat backrests are not locked after
installing Top Tether belts
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci‐
dent or during braking or sudden changes of
direction.
As a result, child restraint systems cannot
perform their intended protective function.
Rear seat backrests that are not locked can
also cause additional injuries, e.g. in the
event of an accident.
Always lock rear seat backrests after
#
installing Top Tether belts.
Observe the lock verification indicator.
#
If the seat backrest is not engaged and locked,
this will be shown on the multifunction display
on the instrument cluster.
If the child restraint system is equipped
with a Top Tether belt:
The risk of injury can be reduced by Top
Tether. The Top Tether belt facilitates an
additional connection between the child
restraint system attached with LATCH-
type (ISOFIX) and the vehicle.
