If your vehicle has rear head
restraints that fold down, always
return them to the full upright
position whenever an occupant is
seated in the seat.
Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the

Reclining Seatbacks
{Warning
Sitting in a reclined position when

The shoulder belt will not be
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

seatback upright. Then sit well
back in the seat and wear the
seat belt properly.
