DESCRIPTION AND OPERATION

DRIVER SEAT BELT WARNING

The driver's seat belt incorporates a seat belt warning lamp in the instrument cluster and chime to remind the driver if the seat belt is not fastened when the ignition is turned ON. The seat belt warning chime will go out after about six seconds, but the seat belt warning lamp will illuminate until fastening the seat belt.

THREE-POINT FRONT SEAT BELT

The front seat belts have four different option.

Emergency Locking Retractor (ELR)

The ELR seat belt is always unlocked, allowing the passenger freedom of movement, except in emergencies such as rapid deceleration, rapid acceleration, or hard cornering maneuvers.

Webbing Locking Retractor (WLR)

The WLR seat belt is mostly the same as ELR seat belt that always unlocked, allowing the passenger freedom of movement. In emergencies such as rapid deceleration, rapid acceleration, or hard cornering maneuvers, it locks retractor and clamp seat belt webbing additionally.

Emergency Locking Retractor (ELR) with Pretensioner

At normal condition, this type of seat belt operates as ELR seat belt. This seat belt contains an electronically controlled pyrotechnic retractor, pretensioner, which reduces seat belt slack when it activated in a head-on or angled front collision. The front seat belt must be replaced after an accident that causes its activation.

Emergency Locking Retractor (ELR) with Pretensioner and Load Limiter

This type of seat belts are standard for western Europe. Normally the seat belt operates in the ELR with pretensioner. However, when it activated, the pretensioner reduce belt slack, and load limiter will give some buffer for reaction of body for safety.

THREE-POINT REAR OUTBOARD SEAT BELT

The rear outboard seat belt has three optional parts. Refer to "Three-Point Front Seat Belt" in this section for details.

TWO-POINT LAP REAR CENTER SEAT BELT

The two-point lap rear center seat belt is a single continuous length of webbing. The webbing is routed from the anchor through latch plate and into a single buckle.

THREE-POINT LAP REAR CENTER SEAT BELT
