1. Fog Lights Indicator

This is one of the few lights that doesn’t signal a problem—it simply means your fog lights are on. Fog lights help illuminate the road during heavy fog, rain, or snow. If you’re not in poor weather conditions, turn them off to avoid blinding other drivers.

2. Airbag Warning Light

This light looks like a seated person with a circle in front of them, representing an airbag. If it comes on, it means there’s a problem with your vehicle’s airbag system. Your airbags may not deploy during an accident, which could increase your risk of injury. Don’t ignore this one—schedule an inspection as soon as possible to ensure your safety.

3. Check Engine Light

Perhaps the most well-known and feared dashboard light, your check engine light can signal a range of issues, from engine trouble to a loose gas cap. While it may not always be urgent, ignoring it could lead to expensive repairs down the road. It's a key symbol when understanding the meaning of all dashboard lights.

4. Low Fuel Warning Light

This icon typically resembles a gas pump and serves as a cue to fill up. While driving a few miles on low fuel might seem harmless, doing it regularly can damage your fuel pump over time. Get in the habit of refueling once this light comes on to avoid unnecessary wear and tear.

5. Coolant Level Warning Light

This light typically looks like a thermometer floating in liquid. It means your engine’s coolant level is low, which can cause overheating. A hot motor can result in severe engine damage, so pull over safely and check your coolant as soon as possible. This is one of those car dashboard symbols and meanings that should never be ignored.

6. Battery Warning Light

When this symbol, shaped like a car battery, illuminates, it indicates a problem with the electrical charging system. It could mean a failing alternator, battery, or another issue that may cause your car to lose power. If you see this light, please have your vehicle taken to Olson Chevrolet to have your electrical system tested immediately.

7. Brake System Warning Light

This warning could indicate that your parking brake is engaged, or it may signal an issue with the braking system, such as damaged brake pads or low brake fluid levels. Don’t take chances with your brakes—your safety depends on them. Knowing the meaning of these dashboard lights can help prevent dangerous driving conditions.

8. Traction or Stability Control Light

This light typically shows a car with squiggly lines beneath it and often flashes when traction control is actively engaged. However, if it persists, it could mean the system has been disabled or there is an issue with the sensors. While your car is still drivable, it's best to have it inspected to ensure you don’t lose grip on slick or uneven roads.

9. Low Tire Pressure Warning Light

Symbolized by an exclamation point inside a tire, this light tells you one or more of your tires are under-inflated. Driving with low pressure reduces fuel efficiency and tire lifespan, and it can increase the risk of a blowout. Check your wheels and inflate them to the recommended pressure to keep your car running safely.

10. Engine Oil Warning Light

This symbol resembles an oil can and signals low oil pressure or low oil levels. Without enough oil, your engine could suffer severe internal damage. If you see this light, check your oil level immediately. If it's low, top it off—or better yet, have your oil changed and inspected by professionals.
