Safety Belt Pretensioners - GMC 2007 Yukon Denali Owner's Manual

4. Buckle, position, and release the safety belt
as described in Rear Seat Passengers on
page 53. Make sure that the shoulder
belt crosses the shoulder.
To remove and store the comfort guide, squeeze
the belt edges together so that you can take
them out of the guide. Slide the guide into
its storage clip on the interior body or storage
pocket on the side of the seat.

Safety Belt Pretensioners

Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are part of the safety belt
assembly. They 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 rollover 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 109.
