What are the vehicle warning lights?

[VonAllison]

There are ten main warning lights: 1. Oil pressure warning light: When illuminated, it indicates the engine oil level or pressure is below standard. Continued driving may cause severe engine wear due to lack of lubrication. 2. Coolant temperature warning light: Displays the temperature of the engine coolant. 3. Engine malfunction light: Shows the engine's operational status, typically in yellow. It lights up during ignition self-check and should turn off after starting. Persistent illumination indicates potential engine system issues. 4. Brake system warning light: If illuminated, first ensure the parking brake is fully released. If it remains lit, check brake fluid level or pad thickness. 5. Power steering warning light: Indicates malfunction in the power steering system. 6. Door/hood open warning light: Warns if doors or hood aren't properly closed. 7. Tire pressure monitoring light: Signals low tire pressure or possible tire damage. 8. Battery warning light: Usually yellow, it should turn off after self-check. 9. ABS warning light: Primarily yellow, failure to light during self-check or persistent illumination indicates potential ABS system faults. 10. Electronic stability control light: Normally indicates system deactivation when lit, and activation when off.

I've been driving for over a decade and have seen all kinds of warning lights come on. The most common is the check engine light - that yellow engine icon indicating an engine issue, possibly a sensor or emissions fault. The battery light means there's a charging system problem, either the alternator or battery is failing. The red oil pressure light signals dangerously low oil pressure - you must pull over immediately. The brake system light indicates braking issues, while the ABS light means the anti-lock system has failed, making skidding more likely during braking. The airbag light relates to crash protection, and the tire pressure light is now standard on new cars, alerting you to unstable tire pressure. If the coolant temperature light comes on, the engine is overheating - shut it off right away. When any of these lights illuminate, don't push your luck - pull over safely and check the manual or call for assistance. Regular maintenance like oil changes and electrical system checks can help prevent these warnings.

As a young driver, I find the dashboard of my Hyundai car has an overwhelming number of warning lights. The engine light is the most common, with a yellow indicator signaling engine issues; the battery light indicates charging system failure; the oil pressure light turns red like an alarm, signaling danger when pressure is low; both the brake light and ABS light are related to braking safety; the airbag light indicates a failure in the protection system; the tire pressure light is very practical, alerting you to changes in tire pressure. I use a mobile app connected to the OBD port to read fault codes, making diagnosis easier. A friend of mine kept driving with the ABS light on, and ended up losing control while braking in the rain, nearly causing an accident. So, don’t ignore warning lights—get them checked or parts replaced at a professional shop. Regular car washes and checking the wiring are key to prevention.

I often help people fix cars. The warning lights include the engine light, battery light, oil light, brake light, ABS light, airbag light, and tire pressure light. The engine light may indicate a bad spark plug or oxygen sensor; the battery light means the alternator isn't charging; low oil pressure can easily burn the engine; the brake light indicates a system oil leak; the ABS light signals a sensor fault; the airbag light suggests a control unit issue; and the tire light means TPMS failure. Use a scanner to read the codes and locate the problem—minor repairs can fix it. Ignoring it may worsen the situation, such as neglecting the oil light, which could lead to an engine overhaul. It's recommended to check fluids and circuits monthly to reduce faults.
