{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts cannot do their
job when you are 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.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety belt
properly.
Do not have a seatback reclined if your vehicle is moving.
