2014 Chevrolet Silverado 3500 HD Crew Cab Owner Manual - Page 79

Seats and Restraints Safety Belt Pretensioners 3-17 Regular and Crew Cab To move the adjuster down for the regular and crew cabs, squeeze the buttons on the sides of the height adjuster and move the height adjuster to the desired position. Extended Cab On the extended cab, push down on the release button and move the height adjuster to the desired position. You can move the adjuster up just by pushing up on the shoulder belt guide. After you move the adjuster to where you want it, try to move it down, without squeezing the buttons for the regular and crew cabs, or without pushing the release button for extended cabs, to make sure it has locked into position. This vehicle has safety belt pretensioners for front outboard occupants. Although the safety belt pretensioners cannot be seen, 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, near frontal, or rear 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 the pretensioners activate in a crash, they will need to be replaced, and probably other new parts for the vehicle's safety belt system. See Replacing Safety Belt System Parts after a Crash on page 3-21.
