[WestonDella]

The reasons for several red lights staying on after a car's self-check are: 1. Leakage of vehicle oil, brake fluid, gasoline, or coolant; 2. Malfunction of the vehicle's braking system; 3. Air leakage in the air pump or air reservoir; 4. Abnormal tire pressure; 5. Loose tire fastening screws; 6. Malfunctioning turn signals, brake indicator lights, lighting, wipers, or horn. The normally lit indicator lights after a car's self-check include: 1. Engine fault light: used to display the working status of the engine, with a yellow color; 2. EPC: the indicator light for the engine electronic stability system; 3. Battery indicator light: used to display the working status of the car battery, with a red or yellow color; 4. Handbrake warning light: used to remind whether the handbrake is released; 5. Seat belt warning light: reminds occupants to fasten their seat belts.
