To shorten the belt, pull the free end of the belt.
Position the lap belt as low as possible on your hips – not on your
waist, then adjust it to a snug fit.

High–positioned and loose–fitting lap belts could cause severe
injuries due to sliding under the lap belt during a collision or
other unintended result. Keep the lap belt positioned as low
on hip as possible.
