Pontiac 2005 Vibe - Manual (Page 21)

4. Push the latch plate into the buckle until 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 1-25.
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. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.
6. The lap part of the belt should be worn low and snug
on the hips, just touching the thighs. In a crash, this
applies force to the strong pelvic bones. And you
would be less likely to slide under the lap belt. If you
slid under it, the belt would apply force at your
abdomen. This could cause serious or even fatal
injuries. The shoulder belt should go over the
shoulder and across the chest. These parts of the
body are best able to take belt restraining forces.
The safety belt locks if there is a sudden stop or
crash, or if you pull the belt very quickly out of
the retractor.
