Seats and Restraints Automatic Safety Belt Tightening System If the vehicle has Adaptive Cruise Control (ACC), it also has the Automatic Safety Belt Tightening System. See Adaptive Cruise Control on page 9-41. Each time the vehicle is started with the front safety belts buckled, the system activates once to tighten the safety belts when the forward vehicle speed exceeds the threshold for activation. The system also activates during emergency braking and/or sudden driving maneuvers and releases when driving conditions return to normal. The system will not activate if the Traction Control/Electronic Stability Control system is not functioning properly. See Traction Control/ Electronic Stability Control on page 9-34. If there is a problem with the Automatic Safety Belt Tightening System, a message displays on the Driver Information Center (DIC). See Safety Belt Messages on page 5-41. Other safety belt functions are not affected by the Automatic Safety Belt Tightening System. 3-17 Rear Safety Belt Comfort Guides This vehicle may have rear safety belt comfort guides. If not, they are available through your dealer. Rear safety belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the shoulder belt away from the neck and head. 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, near frontal, or rear crash if the threshold conditions for pretensioner activation are met. Safety belt pretensioners can also help tighten the safety belts in a side crash or a rollover event. Pretensioners work only once. If the pretensioners activate in a crash, the pretensioners and possibly other parts of the safety belt system will need to be replaced. See Replacing Safety Belt System Parts after a Crash on page 3-20.
