That little red or yellow icon on your dashboard is not a decoration – it's your car trying to tell you something. Ignoring it can turn a small fix into a ₦500,000+ repair. Here's what the most common lights mean and exactly what to do.

🔴 Red Lights – Stop Immediately (if safe)

Brake System Warning

Looks like (! ) or BRAKE. Could mean low brake fluid, worn pads, or a hydraulic leak. Action: Check fluid level. If low, do not drive – call our roadside assistance.

Engine Oil Pressure

Looks like an oil can with a drop. Low oil pressure – engine damage is seconds away. Action: Pull over, turn off engine, check oil level. Top up if needed. If light stays on, tow to workshop.

Coolant Temperature

Looks like a thermometer in waves. Engine overheating. Action: Turn on heater to max (draws heat from engine), pull over safely. Never open the radiator cap when hot – wait 30 minutes.

Battery/Charging System

Looks like a battery with +/-. Alternator not charging. Action: Turn off all non essential electrical loads (AC, radio). Drive directly to a workshop – once battery drains, car will stall.

🟡 Yellow/Amber Lights – Schedule Service Soon

Check Engine Light (CEL)

Looks like an engine outline. Could be anything from a loose gas cap to a failing catalytic converter. Action: If steady, drive moderately and book a diagnostic scan. If flashing, reduce power immediately – possible misfire that damages catalytic converter.

TPMS (Tyre Pressure Monitoring)

Looks like a flat tyre with an exclamation. One or more tyres under‑inflated by 25% or more. Action: Check pressures and inflate to spec (see driver's door jamb).

ABS (Anti‑lock Braking System)

Letters ABS inside a circle. The anti‑lock system has a fault – your normal brakes still work, but the system won't prevent skids. Action: Drive carefully to a workshop.

🟢/🔵 Blue/Green Lights – Informational

High beam (blue), fog lights (green), cruise control active – no action needed.
