1-18 Seats and Restraints After the adjuster is set to the desired position, try to move it down without pushing the button to make sure it has locked into position. If the passenger sensing system detects that there is not a passenger in the right front passenger position, the safety belt pretensioner for that position will not activate. See Passenger Sensing System on page 1-28. Pretensioners work only once. If the pretensioners activate in a crash, they will need to be replaced, and probably other new parts for your safety belt system. See Replacing Safety Belt System Parts After a Crash on page 1-20. 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. Safety Belt Pretensioners This vehicle has safety belt pretensioners for the 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 and near frontal 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. Push down on the release button and move the height adjuster to the desired position. The adjuster can be moved up by pushing on the front of the height adjuster.
