Lap Belt
This section is only for the lap belt. To learn how to
wear a lap-shoulder belt, see Lap-Shoulder Belt on
page 1 21.
The vehicle may have a center seating position. When
you sit in the center front seating position, you have a
lap safety belt, which has no retractor.
To make the belt longer, tilt the latch plate and pull it
along the belt.
Buckle, position, and release it the same way as the lap
part of a lap-shoulder belt.

To make the belt shorter, pull its free end as shown until
the belt is snug.
If the belt is not long enough, see Safety Belt Extender
on page 1 25.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.
