Car warning lights - what do they mean?

Your dashboard lights will appear whenever you turn the key in the ignition. However, you may need to worry if one of them stays on or appears when you’re driving.

It can often be difficult to understand what that flashing light on the dashboard even means.We’ve put together a list of  the most common warning lights used by car manufacturers to assist you and your vehicle.


Engine light - When the check engine light appears it is important that you get this looked at as soon as possible. This light is warning about a potential problem with the engine, which could be a fault electrical sensor or a large mechanical fault. It’s vital to get this checked out to avoid further damage.                                                                                                                                                                          

Brake system warning light  - Ensure your handbrake isn’t engaged slightly. If the light remains on, there is something wrong with the braking system and you need to get this checked out instantly. The brakes are a vital feature on the car to ensure your safety.
Airbag warning light - This light appears as a warning that a fault has been found in the airbag system. A faulty airbag may not deploy in a car accident, therefore it is important you get this looked at asap.

Oil pressure warning - If this remains lit, it can indicate the oil is at a too high temperature or a loss of oil pressure. A lack of oil can result in expensive engine damage, so it is vital that when this sign shows up a professional is called.

Coolant warning light - This is either a sign your engine is overheating or that you’re running low on coolant. If this light appears, you need to check the coolant tank under the bonnet and top up if needed. You also should check for coolant leaks, and get it seen to to avoid a potentially expensive repair bill.

Battery charge warning light - This light indicates a fault with the car’s battery system - faulty battery, poor connection or faulty alternator. A faulty battery will just need replacing, however an alternator fault can be more serious.
Power steering - If this light appears, there could be something wrong with the steering system. This could result in heavy steering, which may make it difficult to manoeuvre the vehicle.
Tyre pressure monitor warning light - This light indicates your tyre pressure is too low, or it could signify a puncture. Take a look at your tyres or if you’re unsure how, our HiQ centres offer a free tyre check.
DPF Light (Diesel) - The diesel particulate filter reduces emissions by removing harmful soot from the exhaust gases. If this is faulty, then you may be releasing a toxic cloud of black smoke every time you accelerate or you could be causing damage to the engine. Get this checked out as the DPF could just be blocked, but can be expensive if you need to replace.

Not all car warning lights are universal, check your handbook if you are still unsure. It is important that you don’t ignore these lights it’s their job is to make you aware of a problem. They can also prevent you from having to call out a breakdown company.
