WARNING Risk of injury or death if the
rear seat backrests are not locked after
Top Tether belts are installed
The rear seat backrests may fold forwards
when you are driving.
As a result, child restraint systems will no lon-
ger be able to perform their intended protec-
tive function. This may also cause additional
injuries.
#
Always lock rear seat backrests after
installing Top Tether belts.
#
Observe the lock verification indicator.
If the seat backrest is not engaged and locked in
place, this will be shown on the display on the
Instrument Display (folding the rear seat back
electrically) or the red lock verification indicator
will be visible (folding the rear seat back mechani-
cally).
¯ If the child restraint system is equipped
with a Top Tether belt:
The risk of injury may be reduced by Top
Tether. The Top Tether belt enables an
additional connection between the child
restraint system attached with LATCH-type
(ISOFIX) (left and right rear seats) or the
seat belt (all rear seats) and the vehicle.
The Top Tether anchorages for the second row of
seats are located on the rear side of the seat
backrest. For the third row of seats, use the Top
Tether anchorage on the rear side of the seat
backrest.
