GENERAL DESCRIPTION AND SYSTEM OPERATION

Driver Seat Belt Warning

The seat belt reminder system is a system alerting with sound and light when the seat belt is unbelted.
The severity of warning level depends on the vehicle status and is signalized for driver with an seat belt warning lamp and sound.
Once the ignition turn on, seat belt warning lamp will turn on for 5 seconds and turn off for 2 seconds regardless of seat belt wearing. After this if the seat belt is unbelted, warning lamp will flash for 90 seconds and then illuminate until the seat belt is belted. At this time if the seat belt is belted, warning lamp will turn off at once.
The seat belt reminder after this will follow the below process according to vehicle status.

Pretensioner Front Seat Belt - Only Western Europe -

The pretensioner front seat belt is standard. It contains a mechanically controlled pyrotechnical retractor which reduces the seat belt slack when it is activated in a head-on or angled front collision. The pretensioner front seat belt must be replaced after an accident that causes its activation.

Three-Point ELR Front and Rear Seat Belt

The three-point emergency locking retractor (ELR) seat belt is always unlocked, allowing the passenger freedom of movement, except in emergencies (rapid deceleration, rapid acceleration, or hard cornering maneuvers).

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 a latch plate and into a single retractor.

Operational and Functional Checks

Caution :
  1. Inspect all seat belt anchor bolts and the screws in order to verify that they are secure.
  2. Inspect the seat belt buckle. The buckle must lock and unlock easily.
  3. After inserting the latch into the buckle, tug sharply on the belt. The buckle must remain locked.
  4. Fully extend the shoulder belt portion to make sure that there is no twisting or tears in the belt.
  5. Let the shoulder belt retract fully. The belt should retract easily.
