Dashboard Warning Lights Explained

One of the most important tools in your car’s system is the dashboard warning light panel. These small icons can seem confusing at first, but each one tells you something important about your vehicle’s health.

In this blog post, we’ll walk through the most common dashboard warning lights and explain what they mean—and what to do when you see them.

Battery Light

What it means: There may be a problem with your car’s charging system, battery, or alternator.

What to do: If the light comes on while you’re driving, your vehicle is likely running on battery power alone. You should have it checked at your local Trail Tire as soon as possible to avoid being stranded.

Oil Pressure Light

What it means: Your engine may not be getting enough oil, or you may be due for an oil change.

What to do: Stop the car as soon as it’s safe. Check your oil level and add oil if needed. If the light stays on, get your vehicle to a Trail Tire right away. Driving with low oil pressure can cause serious engine damage.

Check Engine Light

What it means: Something’s wrong with the engine or emissions system.

What to do: This light can indicate a range of issues—from a loose gas cap to a serious engine problem. It’s best to have a diagnostic scan done to pinpoint the cause. Stop into your local Trail Tire and we can check it.

Tire Pressure Warning Light

What it means: One or more tires may be under-inflated.

What to do: Check your tire pressure and inflate them to the recommended level. Low tire pressure can affect fuel economy and safety, so it’s important that they are set to the correct PSI.

Traction Control Light

What it means: Your car’s traction control system is active or not working properly.

What to do: If it flashes while driving, the system is adjusting for road conditions. If it stays on, the system may be disabled, and you should get it checked.

Coolant Temperature Warning Light

What it means: Your engine is overheating.

What to do: Pull over safely and let your engine cool down. Check the coolant level once it’s safe. Overheating can lead to serious engine damage if ignored.

Washer Fluid Warning Light

What it means: Your windshield washer fluid is low.

What to do: Top up the washer fluid reservoir. This is a simple fix, but important for safe visibility.

Brake System Warning Light

What it means: There may be a problem with your braking system or low brake fluid.

What to do: If this light comes on while driving, check your parking brake first. If it’s not engaged, you could have a serious brake issue. Get your brakes checked immediately.

ABS Warning Light

What it means: There’s a fault in the Anti-lock Braking System.

What to do: Your normal brakes will still work, but the ABS may not. This system prevents wheel lock during hard braking, so it’s best to have this inspected soon.

Seatbelt Warning Light

What it means: A seatbelt isn’t fastened.

What to do: Buckle up! This light is usually accompanied by a chime. It’s there for your safety and may also turn off airbags if not addressed.

Power Steering Warning Light

What it means: There’s a problem with your power steering system.

What to do: You may notice your steering feels heavy or stiff. If this light comes on, check your steering fluid level or have the system inspected.

Other Lights to Be Aware Of:

Airbag Warning Light: Indicates a problem with one or more airbags.

Door Ajar Light: One or more doors aren’t fully closed.

Fuel Warning Light: You’re running low on gas—time to fill up!
