Seats and Restraints Shoulder Belt Height Adjuster The vehicle has a shoulder belt height adjuster for the driver and right front passenger seating positions. Adjust the height so the shoulder portion of the belt is on the shoulder and not falling off of it. The belt should be close to, but not contacting, the neck. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. See How to Wear Safety Belts Properly on page 3‑14. 3-17 Safety Belt Pretensioners 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 and near frontal crash if the threshold conditions for pretensioner activation are met. Press the release button (A) and move the height adjuster to the desired position. The adjuster can be moved up by pushing the slide/ trim up. After the adjuster is set to the desired position, try to move it down without pushing the release button to make sure it has locked into position. Pretensioners work only once. If the pretensioners activate in a crash, the pretensioners and probably other parts of the vehicle's safety belt system will need to be replaced. See Replacing Safety Belt System Parts after a Crash on page 3‑21.
