ger be able to perform their intended protec-
tive function. This may also cause additional
injuries.

If the rear seat backrest is not engaged and
locked in place, the red lock verification indicator
will be visible.

with a Top Tether belt:
The risk of injury may be reduced by Top

additional connection between the child
restraint system attached with LATCH-type
