Reclining Seatbacks
{
WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.
The shoulder belt cannot do its
job because it 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 cannot do its job
either. In a crash, the belt could
go up over your abdomen.
The belt forces would be there,
not at your pelvic bones. This
could cause serious internal
injuries.

WARNING (Continued)
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly.
Do not have a seatback reclined if
the vehicle is moving.
