The seatbelt warning chime warns the seatbelt is not fastened. The seatbelt warning chime sounds a repetitive sequence of four 1-second chime tones for 6 seconds through the front speakers when the driver seatbelt is not fastened and the ignition is transitioned from OFF or ACC to ON or START. The seatbelt warning chime stops sounding when the seatbelt is fastened, when the ignition is transitioned from ON or START to OFF or ACC, or when the chime has sounded for 6 seconds.

The IPC receives the driver seatbelt buckle status message from the GWM over the HS-CAN3.

The GWM receives the driver seatbelt buckle status from the RCM over the HS-CAN2.

When the conditions require the seatbelt warning chime, the IPC sends the IPC chime request message to the ACM and DSP to sound the chime.
