Car Dashboard Warning Lights Explained NZ: Meanings of All 64 Symbols
Dashboard warning lights are one of the most important safety features in any vehicle. They can alert you to a minor issue, a maintenance item, or a serious fault that needs immediate attention.
Many drivers see these symbols every day but are not always sure what they mean or what action they should take. This guide explains the most common dashboard warning lights, what the colours mean, and includes a full numbered reference list of all 64 symbols shown below.
What Do Dashboard Warning Light Colours Mean?
Dashboard warning lights are generally shown in different colours to help indicate urgency.
- Red warning lights usually mean stop as soon as it is safe and investigate the issue immediately.
- Amber or yellow warning lights normally mean a system needs attention soon or should be checked by a professional.
- Green or blue warning lights are usually informational and show that a feature or system is currently active.
Even when a warning light does not seem urgent, it is always best to have it checked before it leads to a more expensive repair.
Most Important Warning Lights to Never Ignore
Check Engine Light
This usually means there is an issue with the engine management or emissions system. It may be something minor, but it can also point to a serious fault that needs urgent attention.
Oil Pressure Warning Light
If this light appears, stop driving as soon as it is safe. Low oil pressure can quickly cause severe engine damage.
Brake Warning Light
This may indicate a braking system issue, low brake fluid, or that the handbrake is still on. If it stays on while driving, the vehicle should be checked immediately.
Battery Warning Light
This indicates a charging system problem, often related to the battery or alternator. The vehicle may continue running for a short time, but it could stop once battery power is depleted.
Coolant Temperature Warning
This shows the engine may be overheating. Pull over safely and allow the engine to cool before continuing.
Tyre Pressure Warning Light
This means one or more tyres may be under-inflated. Driving with incorrect tyre pressure can affect safety, tyre life, and fuel economy.
