Turn Signal On Warning

The BCM activates an audible warning as a reminder that the turn signal has been on for a distance of more than 1.20 km (0.75 mi). The BCM receives the vehicle speed and distance via the vehicle speed signal circuit. The turn signal chime will use a tone that is synchronized with the turn signal flasher. The BCM will activate the turn signal chime when the following occurs:
^ The ignition is ON.
^ Left or right turn signal switch is ON.
^ The vehicle has traveled further than 1.20 km (0.75 mi).
