Dashboard Warning Lights Explained

Engine Management Light

When the engine management light is illuminated it’s often accompanied by tell-tale signs that the engine is not working properly, such as a lack of power as you press the accelerator.

This light could indicate a number of faults, from minor issues like a broken electrical sensor to a much larger mechanical issue, like a fault with your emission control system or catalytic converter.

If the check engine light comes on you should get it checked as soon as you can, as by continuing to drive you risk causing further, potentially irreparable damage to your engine. 

Battery Warning Light

The battery warning light indicates a problem with your car's charging system. It could be due to a problem with your cars electrical system such as a faulty alternator, a loose or damaged belt, or a weak battery.

Ignoring this light could lead to a dead battery and leave you stranded. Have your vehicle's electrical system checked as soon as possible.

Engine Oil Warning Light

The oil pressure warning light implies that either the oil temperature is too high or low oil pressure in your engine. It may be due to low oil levels or a problem with the oil pump. Low oil pressure can cause severe engine damage so it's crucial to pull over, check your oil level, and add oil if necessary.

If the oil levels are fine, then the oil pump may be faulty. In this case consult a mechanic immediately.

Tyre Pressure Warning Light

The tyre pressure warning light indicates that one or more of your tires has low air pressure. Driving on underinflated tires can affect handling, fuel efficiency, and tire longevity.

Check your tire pressures at the next opportunity and inflate them to the recommended levels, which you can find on the inside of the driver’s door or in your owner’s manual.

Brake Warning Light

If this red light remains illuminated after you fully release the parking brake or comes on while driving, this indicates an issue with your car’s braking system. It could mean anything from low brake fluid to worn brake pads or a malfunctioning ABS (Anti-lock Braking System).

The brakes are one of the most important safety features of your car, so it’s important to act immediately when you see this red car warning light.

ABS Warning Light

The ABS warning light indicates a problem with your car's Anti-lock Braking System. It could mean a faulty ABS sensor, a malfunctioning pump, or a damaged control module.

If the ABS light comes on by itself you should still have normal, unassisted braking, so it's safe to continue your journey – but keep your distance, take extra care, and get it checked as soon as possible.

If it comes on with the brake warning light, it could indicate that the brake system is failing and you should stop straight away and call for recovery if you have breakdown cover.

Airbag Warning Light

The airbag warning light indicates a fault in your vehicle's airbag system. It could mean a defective sensor, faulty wiring, or a problem with the airbag deployment mechanism. Since airbags are a critical safety feature, it's important to have this issue addressed promptly.

Engine Temperature Warning Light

This light will come on when the engine is overheating. This could mean that coolant levels are running low. This yellow car warning light will come on when coolant levels are running low, to remind you to top them up.

If this light is red you should stop straight away, as without enough coolant your engine could get so hot that it effectively welds itself together, causing irreparable damage. Stop and wait until the engine has cooled off before checking the gauge on the side of the coolant tank under the bonnet, topping up as required.
