Make sure your seat belt is properly fastened.
The driver and front passenger front seat belt pretensioners are designed to deploy in response to a severe frontal collision.
If the air bag sensor detects an impact from a severe frontal collision, the front seat belts are quickly retracted rearward by the pretensioner so that the belts firmly hold the occupants of the front seats.
The seat belt tensioners are activated even if there are no passengers in the front seat.
This indicator comes on when the ignition switch is in the "ON" or "ACC" position. It will go out after about 6 seconds. This means that the front seat belt pretensioners are working properly.
This warning light system monitors the front air bag sensors, seat belt pretensioner assemblies, warning light indicators, internal wiring system and power supplies.

The seat belt tensioner is controlled via the air bag sensor. The air bag sensor unit consists of a safety sensor and an air bag sensor.
If the seat belt retractor is activated, a functional noise may be heard and a small amount of smoke-like gas may be released. This smoke is harmless and does not indicate a fire.
If the seat belt retractor has been activated, the belt tensioner will remain locked.
Warning! Do not modify, remove, strike or open the seat belt retractors, air bag sensor or electrical wiring. This may cause the seat belt retractors to deploy unexpectedly or cause the system to fail, resulting in serious injury.
