What Are These Vehicle Warning Lights?
Vehicle warning lights can be scary, but they shouldn’t be. After all, they are only there to warn you. That being said, when a warning light pops on the dashboard, you should definitely look into the problem and fix it—or get repairs from a professional.

Fortunately, the most common vehicle warning lights are fairly easy to decipher:

Brake System – This can be caused by a problem with the ABS system or if brake fluid is low. Innocently enough, it can also be caused by an engaged parking brake. If it’s not the latter case, be easy on the brakes until you get the issue resolved.
Battery/Charging Alert – The battery voltage is too low. If you want to avoid being unable to start your car, especially in the winter, check the battery terminals, the alternator belt, and the battery’s overall condition.
Check Engine Light – You’ll need a code reader or the assistance of a professional for this one, as there are hundreds of reasons the check engine light may come on. The most common include faulty oxygen sensors, faulty spark plugs, or a failing catalytic converter, all of which need attention.
Coolant Temperature Warning – Stop the car and pull over in a safe place. Your coolant is too hot, which can lead to the engine overheating. Let the engine cool down and check the coolant level, fans, and radiator cap. Also make sure there are no leaks in the coolant system.
Oil Pressure Warning – Oil pressure is abnormally low and should be checked. Additionally, check the oil level. You may need an oil change.
