Vehicle Pre-Check, Dashboard Warnings and Basic Mechanics
A daily or pre-journey check catches faults before they become breakdowns. Walk around the vehicle: tyres (pressure, tread depth, damage, and the spare), lights and indicators, mirrors, wipers, fluid levels (engine oil, coolant, brake fluid, washer), and look for leaks under the car. Check that the handbrake holds and that the horn works. Know where the jack, wheel brace and warning triangle are kept.
Dashboard warning lights fall into three colour families. Red means stop safely and investigate - oil pressure, coolant temperature, brake system, battery charging, or a door/bonnet not closed. Amber means caution, check soon - engine management, ABS, tyre pressure, low fuel. Green or blue are informational - indicators, headlights, fog lights. A light that stays on after the engine starts, or comes on while driving, is the signal to act; a brief illumination at start-up is normal self-testing.
Traps: assuming an amber light can be ignored indefinitely; confusing the oil-pressure light (stop immediately) with the low-fuel light (refuel soon); not knowing that ABS warning means normal braking remains but skid prevention may not. Tyre tread and pressure questions reward knowing that under-inflation increases heat and wear and worsens handling.
Rule of thumb: red = stop, amber = check soon, green/blue = information. If in doubt about a red light, stop in a safe place and investigate before continuing.
