What do all these symbol, lights and buttons mean?
Have you just got out of your old car and into a brand new one, turned the key and had the dashboard light up momentarily like a christmas tree? It can be a little daunting if you haven’t driven a modern car that’s packed to the eyeballs with new and modern technology, all working towards monitoring your vehicles behaviour and health, to make your motoring life easier.
You could be tempted to ignore any flashing lights, similar to when you may have owned an older car and ignored a grinding or knocking noise, something easily fixed by turning the radio up loud! (this is not a recommendation). Nor is it recommended to attempt any kind of re-wiring of fuses to disable a dashlight bulb (true story).
It is important to remember that all dash lights have a valid purpose, so it is worth noting, what the main ones mean if not all, because they can pre-empt a car breakdown or full-on failure, potentially saving you from an expensive repair bill and keeping you safer on the road.

Engine Warning light If your car’s engine warning light remains on, it’s advice to get it looked at by a professional mechanic to assess the fault that could be affecting your emissions (EOBD).

Power Steering The power steering warning light will illuminate if your fluid levels are low or if there is a fault within the system. Check power steering fluid levels and top-up if necessary. If fluid levels continuously fall, there may be a leak in the system. Steering is possible without the aid of power steering although may become difficult at low speeds. |

DPF |
DPF / Diesel particulate filter warning light When the DPF warning comes on, it’s time to take the vehicle on a longer run, preferably on a faster road such as a dual carriageway or motorway to prompt the DPF to go into ‘regeneration’ mode and burn off soot which will clear any blockage. If this doesn’t fix the light a trip to the garage is a must! |

Engine Temperature warning light Overheating is the most common cause of an irreparably damaged engine, so you should always take a temperature warning light seriously. The most common culprit for when an engine overheats is low or weak coolant. How to check and change engine coolant. On starting your engine this symbol may show as a blue light, this is just the engine warming up and may depending on the make and model of your vehicle. If the symbol turns red, your engine is over heating – safely pull over and turn the engine off to let it cool down. |
 |
Oil Pressure If the oil pressure warning light lights up it is like is says on the tin – your oil pressure is low. This could be a result of a punctured oil pan, a leak or a number of problems. If you run the engine without oil, it will seize because the metal parts won’t be able to move against each other. Do not drive your vehicle if this light is on. How to check and change engine oil |
 |
Tyre Pressure The tyre pressure warning light will become illuminated when the tyre pressure monitoring system detects a possible reduction in tyre pressure, use this as a guide and always keep an eye on your tyres. How to change a wheel |
 |
Battery Alert The battery light indicates a battery charging problem. If the battery light comes on and stays on while you are driving, the most common cause is a broken alternator belt |
 |
Traction Control The traction control system in your vehicle exists as a driving aid during adverse conditions, such as rain, snow, ice, or poorly maintained roads. In the event of this light staying on, a fault has been detected and it’s advised you visit your local dealer centre for an assessment. |
