accident, heavy braking or sudden changes
of direction. As a result, child restraint sys-
tems cannot perform their intended protec-
tive function. Rear seat backrests that are
not locked can also cause additional inju-
ries, e.g. in the event of an accident. This

ling a Top Tether belt. Observe the lock veri-
fication indicator. Adjust the rear seat
backrests so that they are in an upright posi-
tion.
If the rear backrest is not engaged and locked,
the red lock verification indicator will be visible
(Y page 254).
