All About Car Warning Lights

Every driver has experienced having a warning light illuminate on the instrument panel and wondered what it meant. All vehicles have dozens of warning lights to alert the driver when a system is experiencing problems, when the vehicle needs service, or simply when the driver needs to know something. These warning lights can signal issues as mild as needing to close a door, or as serious as needing to have the brake pads replaced.

When you first turn on your vehicle, some of the lights might illuminate as the systems are checked. The lights will then disappear, and only illuminate again when an issue is detected. When a warning light comes on, you’ll want to familiarize yourself with the light before driving much further. This will allow you to figure out just how severe the problem is, and what can be done to fix it. To learn more about any of your vehicle’s warning lights, check out our guide below.

All about each warning light

Warning lights often represent simple issues, like needing to refill the washer fluid or put the gas cap on. The lights can often represent issues that need repairs, though. If you have a warning light that requires an inspection or repair, or simply don’t understand what the warning light means, you should schedule an inspection with a reputable technician, such as the ones from YourMechanic.

Another home run! Really appreciate the flexibility regarding my service appointment. Due to my work schedule I desperately needed a late appointment. So grateful my car is receiving top shelf professional service. Replaced a oil pan drain plug that was seriously damaged and stripped by a competitor that will NEVER get my business again! All services were quickly completed. Thank you so much for another great experience with my.... Your Mechanic Lavell 5 ⭐️ Service consistently.
