Understanding Your Vehicle Dashboard Lights: What They Mean and What to Do About Them
Your car’s dashboard is like its health monitor—lit up with various symbols and lights that communicate important information about the status of your vehicle. While some of these dashboard lights serve as reminders (like the seatbelt sign), others may signal potential problems that require immediate attention. So, what do those dashboard lights really mean, and how should you respond to them? Let’s break it down.
1. Check Engine Light (CEL)
The most dreaded of all dashboard lights, the "Check Engine" light (often represented by an engine symbol), can mean a variety of things. From a loose gas cap to a serious engine issue, it covers a lot of ground. If this light comes on, don't panic. First, check if the gas cap is properly tightened. If it’s secure and the light remains on, it could indicate anything from a faulty sensor to an issue with the emission system. The best course of action is to take your car to one of the service departments at the Folsom Auto Mall to get a diagnostic test.
2. Oil Pressure Warning Light
This light looks like an oil can and signals a drop in oil pressure. Low oil pressure can mean your engine isn’t being properly lubricated, which could lead to damage. If this light comes on, pull over safely and turn off the engine immediately. Check your oil level once the engine has cooled down. If the oil level is fine, it could indicate a problem with the oil pump or a more significant issue, so you should get the vehicle checked as soon as possible.
3. Battery/Charging Alert Light
This light resembles a battery and is a reminder to check your vehicle's electrical system. If it lights up, your battery may not be charging properly, or there could be an issue with the alternator. Or it may simply be time to replace your battery. If this light comes on, it’s best to get your car inspected by a professional, as a failing battery or alternator can leave you stranded.
4. Tire Pressure Monitoring System (TPMS) Light
Represented by a horseshoe shape with an exclamation point inside, this symbol indicates that one or more tires may be underinflated. If you see this light, check your tire pressure when it’s safe to do so. Tires that are underinflated not only decrease fuel efficiency but can also be dangerous. Most vehicles today have a sensor that alerts you to low tire pressure, but it's a good idea to check your tires manually every now and then as well.
5. Brake Warning Light
This red light sometimes spells out the word "BRAKE" or shows an exclamation point inside a circle and it can mean several things. It could indicate that your parking brake is engaged or that there's an issue with the braking system. If it’s a simple parking brake issue, disengaging it should turn the light off. However, if it’s related to brake fluid levels or a problem with the brake system, it’s crucial to get your vehicle checked right away.
6. Coolant Temperature Warning Light
This light looks like a thermometer submerged in liquid and it signals that your engine may be overheating. If you see this light, pull over and turn off the vehicle to prevent further damage. Let the car cool down before checking coolant levels. If the levels are fine and the light persists, you may have an issue with the radiator, thermostat, or water pump.
7. ABS Warning Light
This symbol lights up with the letters "ABS" and indicates a problem with your car’s Anti-lock Braking System. While the car can still function without ABS, it’s best to address the issue before driving in conditions that require maximum braking. If the light is on, have the system inspected by a professional.
8. Airbag Warning Light
This light is usually shaped like a person sitting with a seatbelt on and indicates a malfunction with the airbag system. If this light comes on, it’s a safety concern. Get the vehicle checked at the Folsom Auto Mall to ensure your airbags will deploy in the event of a crash.
Dashboard warning lights are there to give you early warnings about potential problems. Understanding their meanings can help you react promptly and prevent costly repairs. While some issues can be handled with basic maintenance, others require professional attention to ensure your vehicle remains safe and reliable.
