Driver Safety Belt Reminder Light
There is a driver safety belt reminder light on the instrument panel cluster.

When the vehicle is started, this light flashes and a chime may come on to remind the driver to fasten their safety belt. Then the light stays on solid until the belt is buckled. This cycle may continue several times if the driver remains or becomes unbuckled while the vehicle is moving.
If the driver safety belt is buckled, neither the light nor the chime comes on.
