Top 10 Dashboard Warning Lights Meaning & What You Should Do
Have you ever been driving and suddenly noticed a strange symbol light up on your dashboard? It’s easy to ignore it and carry on with your day, but those dashboard warning lights on your car dashboard are your vehicle’s way of telling you something’s wrong.
Whether it’s a minor issue or a critical fault, understanding the dashboard warning lights meaning, is vital for your safety and the health of your vehicle.
In this guide, we explain the car warning lights meaning, what each colour indicates, and when to get your car checked by professional vehicle technicians.
Why Dashboard Warning Lights Matter
Modern cars are smarter than ever, equipped with complex systems to monitor performance, emissions, and safety. Warning lights on your dashboard are part of your vehicle’s diagnostic system. They alert you when something needs attention, from a minor check to a critical failure.
Ignoring dashboard warning lights is an indicator of a serious fault, and continuing to drive despite the warning lights can result in increased repair costs and compromised safety. It’s not just about avoiding breakdowns, it’s about protecting yourself and your passengers.
Dashboard Lights Explained UK: What Do the Colours Mean?
Your dashboard lights are colour-coded to indicate degrees of urgency. Here’s what the colours mean:
- Red Warning Lights: These are serious. Stop the car as soon as it’s safe and seek assistance. It is NOT safe to continue to drive when red warning lights are showing. They can relate to safety systems or critical engine faults, such as the brakes or oil levels.
- Amber/Yellow Warning Light: These are warning signs and mean something needs checking. You can usually continue driving, but should get the vehicle inspected soon.
- Green/Blue Lights: Informational only. These lights tell you a system is on, such as indicators or headlights.
Most importantly, don’t ignore a light even if your vehicle feels fine. Some faults, if left unchecked, can cause further damage or lead to an immediate stop, which could be in an inconvenient location or time.
Top 10 Common Warning Lights on Car Dashboard
1. Engine Warning Light – What to Do
Often shown as a small engine symbol, this light indicates an issue with the engine or emissions system. It could be linked to the catalytic converter, spark plugs, or other components. If the light remains on, have the vehicle inspected. Ignoring it could lead to costly damage or a breakdown.
2. Red – Brake System Warning Light
A red brake light indicates a serious issue with the braking system, possibly low fluid, worn pads, or brake failure. Stop driving immediately and call Tivoli. Brakes are critical for safety.
3. Red – Coolant Temperature Warning Light
This symbol looks like a thermometer in water. It means the engine is overheating or the coolant levels are too low. Pull over safely, allow the engine to cool, and top up the coolant if needed. Overheating can seriously damage your engine and driving an overheating engine can cause irreversible damage.
4. Red – Oil Pressure Warning Light
This red light often appears as an oil can symbol. This light means your engine oil is low or the pressure is insufficient. Driving without oil can destroy your engine in minutes. Stop driving and check your oil level immediately.
5. Red – Battery Charge Warning Light
Usually shaped like a battery, this red light means your battery isn’t charging properly. It could be the alternator or the battery itself. If this light turns on while driving, your car may soon lose power.
6. Red – Power Steering Warning Light
Usually shown as a steering wheel with an exclamation mark, this light means there’s a fault in the power steering system. Steering may feel heavy or unpredictable and unsafe. Don’t delay getting it looked at.
7. Red – Airbag Warning Light
This light means there’s a fault in the airbag system. In the event of a collision, airbags may not deploy, which is a major safety risk. Don’t ignore this one; get your vehicle checked urgently.
8. Amber – Tyre Pressure Monitoring System (TPMS) Warning Light
This symbol looks like an exclamation point in a tyre. It means your tyre pressures are low, which can affect handling, braking, and fuel efficiency. Check pressures and adjust as needed.
9. Amber – Fuel Level Warning Light
This amber light usually looks like a fuel pump symbol and appears when your tank is running low. While it might not seem urgent, running your car on very low fuel can damage the fuel pump over time and reduce overall fuel efficiency. If the light remains after refuelling, it could signal a fault in the fuel level sensor that should be checked by a technician.
10. Amber – ABS (Anti-lock Braking System) Warning Light
If the ABS warning light comes on, it means there’s a fault in the Anti-lock Braking System. While your regular brakes should still work, the ABS won’t function properly, which can affect stopping safely in emergencies or slippery conditions. It’s important to have this system inspected promptly, especially before continuing to drive in wet or icy weather.
Should I Keep Driving If a Warning Light Appears?
This is a question we get a lot.
In some cases, continuing to drive with a warning light may be safe for a short while, especially with amber lights. But in other situations, especially if it’s red, you need to stop driving and seek professional help immediately.
If the light remains, it could mean the system has failed or that damage is already occurring. Either way, the best option is to get the light to turn off the right way by getting the issue fixed.
What If the Light Goes Off On Its Own?
Sometimes, a warning light will flash briefly and then disappear. This could be due to temporary sensor glitches or minor fluctuations. However, if a light disappears but then reappears frequently, that’s a clear sign something’s wrong. Don’t wait, get your car checked.
