What Dashboard Warning Lights Mean (And What You Should Do)
We've all had it happen. You're driving down the road, glance at the dashboard, and suddenly a light appears that you've never seen before. Your first thought is usually one of two things:
"It's probably nothing..."
or
"Oh no, how expensive is this going to be?"
Dashboard warning lights are your vehicle's way of communicating with you. Some lights are simple reminders, while others are warnings that need immediate attention. Ignoring them can turn a small issue into a much bigger repair bill.
Here's a breakdown of some of the most common warning lights and what you should do if they appear.
Check Engine Light
The check engine light is one of the most common—and frustrating—warning lights because it can mean many different things.
Possible causes:
- Loose gas cap
- Faulty sensor
- Spark plug issues
- Emissions problems
- More serious engine concerns
What you should do:
- If the light is solid, schedule service soon. Call our shop at 913-538-9700
- If the light is flashing, reduce speed and safely stop driving if possible. A flashing light can indicate a more serious issue. Call us immediately at 913-621-3200 or the shop at the number above.
Don't ignore it: Small problems can become expensive repairs if left alone.
Oil Pressure Warning Light
This light usually looks like an oil can.
Possible causes:
- Low oil level
- Oil leak
- Oil pump issue
- Loss of oil pressure
What you should do:
- Pull over safely as soon as possible and call the shop at 913-538-9700
- Turn off the vehicle.
- Check oil level if you're comfortable doing so.
Don't ignore it: Driving with low oil pressure can cause severe engine damage.
Battery Warning Light
This doesn't always mean your battery itself is bad.
Possible causes:
- Alternator issue
- Weak battery
- Charging system problem
- Loose battery connection
What you should do:
- Limit unnecessary electrical usage (radio, seat heaters, etc.).
- Have your charging system checked soon.
Don't ignore it: Your vehicle could eventually stop running or fail to restart.
Tire Pressure Warning Light (TPMS)
This warning looks like a horseshoe with an exclamation point.
Possible causes:
- Low tire pressure

- Slow leak
- Tire puncture
What you should do:
- Check tire pressure immediately.
- Add air if needed.
- Inspect tires for damage.
Don't ignore it: Improper tire pressure affects handling, fuel economy, and tire life. Feel free to give the shop a call at your earliest convenience and they can take a look at it for you.
Engine Temperature Warning Light
This indicates your engine may be overheating.
Possible causes:
- Low coolant
- Cooling system leak
- Thermostat failure
- Water pump problems
What you should do:
- Pull over safely. Once again, call our shop ASAP
- Turn off the vehicle. Do NOT continue driving the vehice!
- Allow the engine to cool before opening anything under the hood.
Don't ignore it: Severe overheating can lead to major engine repairs.
Brake Warning Light
This warning may indicate several issues.
