Sitting in a reclined position when the
vehicle is in motion can be dangerous.

your body. Instead, it will be in front of
you. In a crash, you could go into it,
receiving neck or other injuries.

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.
Do not have a seatback reclined if the
vehicle is moving.

try to adjust a driver seat while the
vehicle is moving. Adjust the driver seat
only when the vehicle is not moving.

move forward in a sudden stop or crash.
That could cause injury to the person
sitting there. Always push and pull on
the seatbacks to be sure they are locked.
