!
A manually adjusted lap belt Ì is tightened
by pulling on the excess belt while pushing
down hard on the car bed. However, you may
have trouble tightening the belt because of the
upright angle at which you must pull. You may
have to unbuckle the seat belt, estimate a seat
belt length that will make the seat belt very
tight, then buckle it again.
