{Warning
Sitting in a reclined position

against your body. Instead, it
will be in front of you. In a
crash, you could go into it,
receiving neck or other
injuries.
The lap belt could go up
over your abdomen. The belt
forces would be there, not
at your pelvic bones. This
could cause serious internal
injuries.
For proper protection when
the vehicle is in motion, have
the seatback upright. Then
sit well back in the seat and
wear the seat belt properly.
