Warning Light Guide

A practical guide for Casterton and district drivers. These dashboard-style examples are here to help you recognise the light, decide whether to stop, and choose the right next step.

Quick rule

Red warning light: stop somewhere safe and get advice before driving further. Amber warning light: book the vehicle in soon. Flashing engine light: avoid driving if possible because continued driving can cause damage.

Warning symbols can vary slightly by make and model, but these examples match the common instrument-cluster style used across many vehicles.

Common warning lights and what to do

These are general guidelines only. If the car feels unsafe, smells hot, loses oil/coolant, loses braking assistance, or starts running badly, stop safely and call for help.

Flashing engine light

Call before driving far

A flashing check engine light often means a misfire. Continued driving can damage the catalytic converter and make the repair more expensive.

Check engine light

Book it in

Can relate to emissions, sensors, misfires, fuel trims, boost faults or many other systems. We scan the vehicle, test the cause and explain the options.

ABS / traction / stability lights

Book diagnosis

The vehicle may still brake, but ABS, traction control or stability systems may be disabled. It should be checked before it becomes a safety problem.

Airbag / SRS light

Book diagnosis

The airbag system may not operate correctly in a crash. We can test SRS faults, seat wiring, module communication and related electrical issues.

DPF / diesel warning light

Book soon

Diesel warning lights can relate to soot loading, sensors, EGR, boost or regeneration problems. Early testing can avoid expensive damage.

Tyre pressure light

Check pressures

Check tyre pressures when safe. If the light stays on, there may be a puncture, sensor issue or pressure monitoring fault.

Key / immobiliser warning

Key service may be needed

If the key light is on or the vehicle will not recognise the key, it may be a key, transponder, immobiliser or wiring issue.

Service reminder

Book service

A service reminder is not usually an emergency, but it is a good time to book routine maintenance before small problems become expensive.

Before you call or book

If it is safe, note the vehicle make and model, the exact warning message, whether the light is red, amber or flashing, and what the vehicle was doing when it appeared. Photos of the dash warning can help.

We commonly help with warning lights on everyday local vehicles including Toyota Corolla, Toyota Hilux, Ford Ranger, Mazda, Hyundai, Kia, Mitsubishi, Nissan, Isuzu and Holden models.

Waiting while we check it?

Waiting customers are welcome to ask about a free cappuccino while the vehicle is with us.
