4.3.6. Acoustic and visual seat belt warning

All vehicles with Crash Safety Module come standard with an acoustic and visual seat belt warning. The Crash Safety Module detects whether the driver and front passenger have fastened their seat belt. If not, a corresponding acoustic and visual indicator reminds them to fasten their seat belt. Both seat belt buckle switches are monitored separately.
