2010 GMC Savana 2500 Cargo Owner's Manual - Page 50

Shoulder Belt Height Adjuster The vehicle has a shoulder belt height adjuster for the driver and right front passenger positions. Adjust the height so that the shoulder portion of the belt is centered on the shoulder. The belt should be away from the face and neck, but not falling off of the shoulder. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. To move it down, pull on the center adjuster control labeled PULL. You can move the height adjuster up just by pushing up on the shoulder belt guide. Safety Belt Pretensioners If the GVWR (Gross Vehicle Weight Rating) of the vehicle is below 8,500 lb (3 855 kg) then the vehicle has safety belt pretensioners for the front outboard occupants. See Loading the Vehicle on page 5-17 to locate the certification label which contains the GVWR. 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 the 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 Restraint System Parts After a Crash on page 2-80. After the adjuster is set to the desired position, try to move it down without pushing in to make sure it has locked into position. 2-26
