Mercedes-Benz C-Class (W205) 2015 - 2021 Owners Manual / Occupant safety / Safely transporting children in the vehicle / 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 accident 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 rear seat backrest is not engaged and locked, the red lock verification indicator will be visible.

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.
