TELL-TALE LAMPS
Tell-tales indicate various conditions by lighting. In general, yellow indicates system status and red indicates a fault
or warning. Tell-tales are located in RH and LH clusters, in the instrument cluster. Some tell-tales are accompanied
by a buzzer or bell. At system start-up, tell-tales light briefly to show that the LEDs work.
