All the service reminder indicators except the open door warning light and SRS airbag warning light should come on. The "ABS" warning light and "TRAC OFF" indicator/warning light go off after about 3 seconds. If any service reminder indicator or warning buzzer does not function as described above, either the bulb is burned out or the circuit is in need of repair. Have it checked by your Toyota dealer as soon as possible. 55
