Cadillac 2008 SRX - Manual (Page 32)

To unlatch the belt, push the button on the buckle.
The belt should go back out of the way.
Before you close a door, be sure the belt is out of
the way. If you slam the door on it, you can damage
both the belt and your vehicle.
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for front
outboard occupants. Although you cannot see them,
they are part of the safety belt assembly. They can help
tighten the safety belts during the early stages of a
moderate to severe frontal or near frontal crash if the
threshold conditions for pretensioner activation are met.
And, if your vehicle has side impact airbags, safety
belt pretensioners can help tighten the safety belts in a
side crash or a rollover event.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and probably other
new parts for your safety belt system. See Replacing
Restraint System Parts After a Crash on page 1-73.
