Top Tether

Top Tether provides an additional connection
between the child restraint system secured
with ISOFIX and the vehicle. It helps reduce
the risk of injury even further. If the child
restraint system is fitted with a Top Tether
belt, this should always be used.
Important safety notes
G WARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci-
dent, heavy 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. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after fitting a
Top Tether belt. Observe the lock verification
indicator.
If the rear seat backrest is not engaged and
locked, this will be shown in the multifunction
display in the instrument cluster. A warning
tone also sounds.
