Quick Answer
Dashboard lights use colour and symbols to show information or warn of a fault. Red lights can indicate an urgent safety or mechanical issue, amber lights usually require attention, and green or blue lights often show that a system is operating. Always check the vehicle handbook.
Why Learners Should Understand Warning Lights
You do not need to become a mechanic, but you should recognise when it may be unsafe to continue. Warning lights may also be discussed during vehicle-safety training and show-me/tell-me preparation.
Engine Management Light
An amber engine symbol can indicate a fault affecting the engine or emissions system. If it flashes, the issue may be more serious.
Follow the manufacturer's guidance and seek professional advice. Do not ignore changes in performance, smoke or unusual noise.
Oil Pressure Warning
A red oil-can symbol can indicate low oil pressure. Continuing to drive may cause major engine damage.
Stop in a safe place, switch off the engine and follow the handbook or breakdown guidance. Do not simply add oil without checking the correct procedure and level.
Battery or Charging Warning
A red battery symbol can indicate that the charging system is not working correctly. The car may eventually lose electrical power.
Move to a safe location and seek assistance rather than continuing a long journey.
Brake Warning Light
This may appear when the parking brake is applied, but if it remains on after release it may indicate low brake fluid or another braking fault.
Treat unexpected red brake warnings seriously and stop safely.
Tyre-Pressure Monitoring Light
An amber tyre symbol can indicate that one or more tyres are underinflated. Check for visible damage and use the recommended pressures shown in the handbook or vehicle label.
A sudden pressure loss may indicate a puncture.
ABS Warning
An ABS warning can mean the anti-lock braking system has a fault. Normal braking may still operate, but the anti-lock function may not work as intended.
Arrange professional inspection and avoid assuming the vehicle is fully safe.
Coolant Temperature Warning
A red temperature symbol can indicate overheating. Stop safely and allow the engine to cool.
Never remove a hot coolant cap because pressurised coolant can cause serious burns.
Airbag and Seatbelt Warnings
A seatbelt light reminds occupants to buckle up. An airbag warning can indicate a fault in the supplementary restraint system and should be checked professionally.
What to Do During a Lesson
Stay calm, tell the instructor and follow their directions. The instructor is responsible for deciding whether the lesson can continue safely.
Next Step
Ask your instructor to show you the main lights in the tuition car. Learn the meaning of the most important red and amber warnings before driving independently.
