it clicks.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough,
see Safety Belt Extender on page 42.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
5. Move the shoulder belt height adjuster to the
height that is right for you. Improper shoulder
belt height adjustment could reduce the
effectiveness of the safety belt in a crash. See
Shoulder Belt Height Adjustment on page 34.
6. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the
safety belt through the latch plate to fully
tighten the lap belt on smaller occupants.
