What do the lights on the dashboard indicate after the engine starts?

[OGianna]

One scenario is when the light illuminates for 2 seconds and then turns off during engine startup, which is part of the vehicle's circuit system self-check function. The other situation is when a warning light remains on after the self-check, indicating a fault in a certain electronic control system. Dashboard indicator light descriptions: 1. Battery indicator: Displays the working status of the battery. It lights up when the ignition is turned on and turns off after the engine starts. If it doesn't illuminate or stays on continuously, the generator and circuit should be checked immediately. 2. Fuel indicator: Warns of low fuel. When this light comes on, it means the fuel is nearly depleted. Generally, the vehicle can still travel about 50 kilometers after this light appears. 3. Washer fluid indicator: Shows the level of windshield washer fluid. If the fluid is nearly empty, this light will illuminate to remind the owner to refill. The light turns off after adding cleaning fluid. 4. Electronic throttle indicator: Commonly seen in Volkswagen models. During vehicle self-check, the EPC light will illuminate for a few seconds and then turn off. If there's a fault, this light stays on, and maintenance should be performed promptly. 5. Front/rear fog light indicators: These lights show the working status of front and rear fog lights. Both lights illuminate when fog lights are activated. 6. Turn signal indicators: When turn signals are activated, the corresponding light flashes at a certain frequency. When the hazard warning lights are pressed, both lights illuminate simultaneously. The indicators automatically turn off after the turn signals stop. 7. Seatbelt indicator: Shows seatbelt status. Depending on the vehicle model, the light may illuminate for several seconds as a reminder or stay on until the seatbelt is fastened. Some vehicles may also have an audible alert.
