& WARNING Risk of accident if seat and
seat backrest are not engaged
If the seat and seat backrest are not engaged
they could fold forwards, e.g. when braking
or in the event of an accident.
This poses the following risks in particular:
A seat or seat backrest that is not
R
engaged can push the vehicle occupant
against the seat belt. The seat belt would
then not be able to provide the intended
protection and could cause additional
injury.
A child restraint system would no longer
R
be supported correctly or positioned cor‐
rectly and would no longer perform its
intended function.
The seat backrest cannot restrain objects
R
or goods in the cargo compartment.
Always ensure that the seat and seat back‐
rest are engaged, especially:
before passengers travel on a seat with
R
the easy entry and exit feature.
after adjusting the seat.
R
after the easy entry and exit feature is
R
used.
after the cargo compartment enlarge‐
R
ment has been folded down.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.
If you no longer require the folded-down rear
seat backrest as a loading area, fold the rear
seat backrest back into place.
Make sure that the red marking of the lock verifi‐
cation indicator is no longer visible. Otherwise,
the seat backrest is not locked.
Requirements:
Vehicles with center rear seat backrest: the
R
center rear seat backrest is not in the cargo
compartment floor position.
Vehicles with a folding rear armrest: the rear
R
armrest has been folded up.
