or lift the seatback and push it

vehicle.

make sure it is locked.
Warning
A safety belt that is improperly
routed, not properly attached,
or twisted will not provide the

sure that the safety belts are
properly routed and attached, and
are not twisted.

mini-latch to the mini-buckle. Do
not let it twist.
