Third Row – Lap Belt - GMC Yukon Denali 2003 Owner's Manual

Third Row – Lap Belt
When you sit in the center seating position in the third
row, 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.
1-40
To make the belt shorter, pull its free end as shown
until the belt is snug. Buckle, position and release it the
same way as the lap part of a lap-shoulder belt. If
the belt isn't long enough, see Safety Belt Extender on
page 1-47 .
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.
