Orange or Yellow Light:

  • Inspect Gas Cap: Check and tighten the gas cap. If the light remains on after a few driving cycles, it may require further diagnostics.
  • Diagnostic Check: Use an OBD-II scanner to read the diagnostic trouble codes (DTCs) stored in the car’s computer. Most auto parts stores offer this service for free.
  • Mechanic Visit: Schedule an appointment with a mechanic to address the identified issues.
