Understanding Your Car’s Dashboard Warning Lights

Modern vehicles are equipped with a rainbow of warning lights that can be confusing or alarming. Knowing what each symbol means helps you address issues promptly and avoid costly repairs. Here’s a guide to the most common dashboard lights and what to do when they illuminate.

Check engine light

Appearance: A yellow or orange engine icon.

Meaning: Indicates a problem in the engine management or emissions system. Causes range from a loose fuel cap to a failing catalytic converter. If the light is steady, schedule service soon; if it flashes, reduce speed and seek immediate assistance.

Battery/charging light

Appearance: A battery icon.

Meaning: Suggests the charging system isn’t working properly—possibly a failing alternator, battery or serpentine belt. Turn off non‑essential electrical accessories and drive to a repair shop. If the battery voltage drops too low, the engine may stall.

Oil pressure light

Appearance: An oil can symbol.

Meaning: Low oil pressure can lead to catastrophic engine damage. Pull over safely and shut off the engine. Check your oil level; if it’s low, add oil. If the light remains on, call a tow truck.

Temperature warning light

Appearance: A thermometer over wavy lines.

Meaning: The engine is overheating. Turn off the air conditioner and turn on the heater to help dissipate heat. Pull over, wait for the engine to cool and check coolant levels. Driving an overheating vehicle can warp the cylinder head.

ABS light

Appearance: Letters “ABS” inside a circle.

Meaning: There’s a problem with the anti‑lock braking system. Your brakes will still work, but the anti‑lock function may not engage on slippery surfaces. Drive cautiously and schedule service.

Airbag light

Appearance: A person with a deployed airbag.

Meaning: The supplemental restraint system has a fault. Your airbags may not deploy in a crash or could deploy unexpectedly. Seek immediate diagnosis.

Tyre pressure monitoring system (TPMS)

Appearance: A cutaway of a tyre with an exclamation point.

Meaning: One or more tyres are underinflated. Check pressures and inflate to the recommended PSI. Persistent TPMS lights may indicate a faulty sensor.

Dashboard warning lights are your car’s way of communicating urgent issues. Familiarise yourself with these icons and act accordingly—ignoring them can lead to more serious problems. If in doubt, contact a professional via Karmeka’s network of mechanics to diagnose and fix any issues.
