Seating and Safety Restraints The safety belt pretensioner removes some slack from the safety belt system at the start of a crash. The safety belt pretensioner uses the same crash sensor system as the front airbags and Safety Canopy௢ system. When the safety belt pretensioner deploys, the lap and shoulder belt are tightened. When the Safety Canopy௢ system and/or the front airbags are activated, the safety belt pretensioners for the driver and right front passenger seating positions will be activated when the respective seatbelt is properly buckled. The driver and the right front passenger seat belt system (including retractors, buckles and height adjusters) must be replaced if the vehicle is involved in a collision that results in deployment of front air bags or Safety Canopy௢ and safety belt pretensioners. Refer to the Safety belt maintenance section in this chapter.
