If the seatback is not locked, it could
move forward in a sudden stop or crash.
That could cause injury to the person
sitting there. Always push and pull on the
seatback to be sure it is locked.If the seats have manual reclining seatbacks,

{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. 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.

To return the seatback to the upright position,
push the seatback rearward until it latches. After
returning the seatback to its upright position,
push and pull on the seatback to make sure it
is locked.
