WARNING
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.

WARNING
A safety belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash.
The person wearing the belt could
be seriously injured. After raising
the rear seatback, always check
to be sure that the safety belts
are properly routed and attached,
and are not twisted.
To return the seatback(s) to the
upright position:
1. Lift the seatback up and push it
all the way rearward.
2. Reach under the front seat and
lift the cushion while moving it
rearward until it latches.
3. Pull forward on the seatback
and push down on the seat
cushion to make sure the seat
is securely in place.
