The Dashboard Lights You Should Never Ignore
Picture the scene: you're driving along as normal, everything is fine, when suddenly a warning light appears on your dashboard.
What do you do? Ignore it and hope it disappears? Panic? Or try to figure out what your car is trying to tell you?
Dashboard symbols can vary between brands and models, so your owner’s manual should always be your first reference. International standards do, however, ensure that many warning symbols are recognisable across different makes.
Here are five key warnings every driver should be familiar with on their dashboard:
1. Oil pressure warning
Usually represented by an oil-can symbol.
Low oil pressure can put your engine at risk of serious damage. If the warning appears while driving, pull over safely, switch off the engine, and check the oil level. If required, consult the owner's manual and call for roadside assistance.
2. Engine temperature warning
Generally, displayed as a thermometer with wavy lines underneath.
This may indicate that your engine is overheating, and continuing to drive can quickly cause serious damage. Pull over safely and switch off the engine. Allow the car to cool before opening the radiator cap to check the coolant, and, if necessary, consult the owner's manual and call for roadside assistance.
3. Brake system warning
Often displayed as an exclamation mark inside a circle or a brake-related symbol.
A red warning light can illuminate if your parking brake is on, but if it remains engaged after you release it, it could signal low brake fluid or a hydraulic issue. Stop driving, check the owner's manual, and if necessary, call for roadside assistance and get the system checked immediately.
An amber brake system warning light can be an indication of an ABS (Anti-lock braking system) issue or brake pad wear. It doesn’t mean your brakes will fail immediately, but it does signal a fault that needs to be looked at as soon as possible.
4. Battery or charging-system warning
The battery system warning light usually appears as a rectangle with a plus (+) and minus (–) sign, resembling a traditional car battery.
This symbol doesn’t necessarily mean you need a new battery. It can signal a fault in the vehicle’s charging system, such as the alternator, wiring, or voltage regulator. Consult the owner's manual and take the car to a garage to have it checked out straight away.
5. Engine malfunction or "check engine" warning
Usually in the shape of an engine.
Not every 'check engine' light means you need to stop immediately, but it should never be ignored.
A steady 'check engine' light means you should book a garage visit promptly.
But if it flashes or occurs together with poor performance, an unusual noise, smoke or other warning lights, stop driving, consult the owner's manual and call for roadside assistance.
Motor Warranties
Because the appearance and required response to a warning light can vary by vehicle, the owner's manual remains the definitive guide for each car.
And when a warning light turns out to be something serious, the repair could involve mechanical or electrical components.
