What is a dashboard warning light?
- Oil Pressure Light. The red oil pressure warning light might indicate a low engine oil level in the shape of an old oil can with a drop of oil dripping from its spout.
- Engine Temperature. Shaped like a partially submerged thermometer, the engine temperature light can illuminate blue or red. If it activates red, it indicates the engine is overheating.
- Battery. Unmistakably shaped like a battery, this red warning light indicates that something within the vehicle’s charging system has failed or is failing.
- Brake System. The light is an exclamation point surrounded by a circle inside parentheses. Once the vehicle is started, it will remain illuminated to alert the driver if the parking brake is engaged.
- Fog Lights. We'll start with a dash light that isn't technically a warning light. The fog light symbol looks a lot like the one used for the regular headlights, albeit with a squiggly line in front of it instead of three lines that look like beams.
- Low Tire Pressure. Modern cars come with tire pressure monitoring systems and the little exclamation point inside of a half-circle merely means one or more of your tires have low pressure.
- Engine Oil Warning Light. Cars have been able to monitor their engine's oil pressure for years now. If you've seen what looks like a gravy boat light pop up in your dash it means there's a problem with your engine oil pressure.
