Seating and Safety Restraints Safety belt pretensioner Your vehicle is equipped with safety belt pretensioners at the driver and front passenger seating positions. The safety belt pretensioners activate during frontal collisions, and in side collisions and rollovers. A safety belt pretensioner is a device which tightens the webbing of the lap and shoulder belts in such a way that they fit more snugly against the body. WARNING: The driver and front passenger safety 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 airbags, seat-mounted side airbags and Safety Canopy , and safety belt pretensioners. WARNING: Failure to replace the safety belt assembly under the above conditions could result in severe personal injuries in the event of a collision. Safety belt extension assembly If the safety belt is too short when fully extended, a 9 inch (23 cm) or 12 inch (31 cm) safety belt extension assembly can be added (part numbers 611C22-A and 611C22-B respectively). These assemblies can be obtained from an authorized dealer. Use only extensions manufactured by the same supplier as the safety belt. Manufacturer identification is located at the end of the webbing on the label. Also, use the safety belt extension only if the safety belt is too short for you when fully extended. WARNING: Do not use extensions to change the fit of the shoulder belt across the torso. Safety belt warning light and indicator chime The safety belt warning light illuminates in the instrument cluster and a chime sounds to remind the occupants to fasten their safety belts. 120 2009 Mariner (mrn) Owners Guide, 2nd Printing USA (fus)
