How to quickly handle 6 important warning lights on cars that drivers need to know

1. Temperature warning light

Engine temperature is higher than standard (engine overheating). Possible causes: Low coolant or cooling system failure; Thermostat or ventilation fan may be running continuously, causing the engine to consume more fuel.

How to handle:Stop the car immediately, check the coolant and add more if the coolant is low or empty. Then leave the car idling for a while (at least 30 minutes), turn on the engine and check if the temperature warning light is still on... If the light is still on, call a tow truck to have the car checked. Do not try to start the car because excessive engine temperature can cause the engine to seize, warp or destroy the engine.

2. Low oil pressure warning light

When this light comes on, it means the oil pressure in the engine may be too low (low oil); the oil pump may be faulty or the inlet line may be clogged. Or the oil being used may be of the wrong viscosity compared to the vehicle manufacturer's recommendations.

How to handle:Stop the vehicle immediately and check the oil level. It is best to call a tow truck as lack of oil can cause the engine to seize and the engine parts will not be lubricated/cooled, causing engine damage.

3. Automatic transmission oil temperature warning light

The transmission oil temperature is too high, possibly due to the vehicle running continuously at high speed for a long time or the transmission oil is not up to standard.

How to handle:Slow down or stop the vehicle to cool. Have the vehicle inspected if this light comes on frequently.

4. Electric power steering (EPS) warning light

When the electric power steering warning light is on, the cause is that the power steering sensor may be faulty or damaged; the EPS electric power steering system is malfunctioning.

How to handle:The power steering sensor can be realigned with a specialized machine or replaced (or the entire sensor assembly) depending on the condition; Have the vehicle inspected, especially if the steering wheel is misaligned and difficult to control (heavy feeling when turning the steering wheel).

5. Anti-lock braking system (ABS) warning light

This light comes on when the wheel sensors detect that the anti-lock braking system (ABS) is not working properly. Other causes include one of the ABS sensors being dirty or broken; the vehicle being stuck in mud or the wheels spinning; or the driver performing a “drag run” and stopping the vehicle quickly enough to “trick” the ABS system.

How to handle:You should take your car to the garage for inspection.

6. Catalytic converter fault warning light

Catalytic converter failure is most commonly caused by a weak ignition system that does not burn the fuel completely.

(The catalytic converter is shaped like a tailpipe, containing precious metals inside - catalysts for the chemical reaction that burns excess gasoline and CO into water vapor and CO2, which is less toxic to the environment).

How to handle:Need to quickly get the car checked.
