GMC 2005 Canyon - Manual (Page 31)

Center Front Passenger Position
Lap Belt
If your vehicle has a 60/40 split front seat, someone can
sit in the center 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.
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 is not
long enough, see Safety Belt Extender on page 1-31.
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.
