OVERVIEW

There is a 3 point seatbelt installed at each seat position. Each seatbelt has an emergency locking retractor functionality.

The emergency locking retractor function incorporates a lift shaft locking system with webbing sensor and vehicle sensing activating mechanisms. The webbing sensor activates the locking mechanism when the webbing is subjected to a sharp pull. The webbing sensor activates the locking system when the vehicle is subjected to sudden deceleration or severe tilt angle.

A pretensioner is incorporated into the retractors of the front row seatbelts, the outer second row seatbelts and the third row seatbelts (if equipped). The pretensioners are pyrotechnic devices that are controlled by the RCM in the Supplementary Restraint System (SRS).

There are 2 types of occupant monitoring:

• In all markets except NAS market, vehicles have an occupant detection sensor.
• In NAS markets, vehicles have an OCS and passenger seat include an occupant detection sensor.

Depending on vehicle specification and market, the seatbelts may also have:

• An automatic locking retractor equipped to all passenger seats (NAS market vehicles).
• A seatbelt pretensioner assembly incorporated into the anchor of the driver seatbelt (NAS and Europe market vehicles).
• A pretensioner incorporated into the anchor of the passenger seatbelt (NAS market vehicles).
• A load limiter actuator incorporated into the retractor of the second row seatbelt and third row seatbelt (if equipped).

A seatbelt reminder system warns the driver when 1 of the following occurs:

• The seatbelt of an occupied front row seat is not fastened.
• A front or rear seatbelt is unfastened during the trip.

North American Specification Market Vehicles

In NAS market, vehicles are equipped with the occupant classification sensor system.

Where an automatic locking retractor is activated, no further webbing can be drawn from the seatbelt retractor, prior to disengagement of the automatic locking. The feature can be mistaken as a jammed seatbelt retractor.
