What Do My Vehicle Warning Lights Mean?
Vehicle warning lights can be scary and confusing, but they lose a lot of their threatening glow when you find out what they really mean, and how to deal with them.
The first thing to remember is that getting a technician to turn off the warning light without fixing the underlying problem won't bring about any good. That just delays disaster.
Fortunately, you may not even need to visit a shop if you know what you're doing and if you know what the vehicle warning lights mean. So let's get started on the ones you are most likely to see.
Coolant Temperature Warning
This is the most urgent warning light because it means that your coolant and thus your engine is overheating. Stop in a safe area and let the engine cool down. Check for leaks in the coolant system, then check the coolant level, fans, and radiator cap.
Check Engine Light
There are too many things that can cause this annoying little light to pop up than we can name, like faulty spark plugs or O2 sensors. Use a code reader to find out what the problem is or ask a professional.
Oil Pressure Warning
Oil pressure is below recommended levels. Your car is likely in dire need of an oil change. Check oil level and pressure.
Battery/Charging Alert
Your battery's voltage levels are too low. This can be caused by the alternator belt or battery terminals. Alternatively, it can also mean that your battery is old and needs replacing.
Brake System
First, check that your parking brake isn't on. If it isn't, you may have a problem with the anti-lock braking system (ABS) or low brake fluid. Until the issue is resolved, be very gentle under braking and avoid situations that would force you to make an emergency stop.
