Demystifying the Dashboard: Understanding Car Warning Lights

Many warning lights on modern dashboards indicate automotive health and status. Understanding warning lights is crucial for vehicle safety and maintenance. Let’s find out common vehicle warning lights and what to do when they show.

Check Engine Light

The check engine light is easily misconstrued. An engine sign indicates a fault found by the vehicle’s on-board diagnostics system. A gas cap leak or catalytic converter failure may be the cause. Check the gas cap tightness when this light turns on. Check your owner’s manual and schedule a mechanic’s diagnostic check promptly if the light stays on.

Oil Pressure Warning Light

Engine health depends on oil pressure warning lights that resemble leaky oil cans. Engine lubrication may be poor with low oil pressure. Low oil pressure might result from low oil levels, a damaged pump, or a clogged filter. Avoid engine damage by stopping immediately when this light appears. Check and add oil. If the problem persists, seek expert diagnosis and treatment.

Tire Pressure Monitor Light

TPMS lights with horseshoe exclamation marks indicate underinflated tires. It affects handling, fuel efficiency, and tire life. Use a tire pressure tester to inflate the tires to the owner’s manual or driver’s side door jamb recommendations when this light appears. Check tires for slow leaks from punctures or damage.

Battery Warning Light

Vehicle charging system malfunctions when battery warning light comes on. A defective alternator, battery, or electrical connections may cause this. Use less radio and AC if this light comes on to save battery power. Drive safely since a dead battery may prohibit starting. A mechanic can inspect the charging system and battery terminals for corrosion or loose connections.

System Brake Warning Light

If the brake warning light, commonly “BRAKE,” is on, the system is malfunctioning. Low brake fluid, damaged pads, or a defective ABS could cause this. Check and apply brake fluid when this light appears. If the light persists, have a brake specialist inspect it. Brake failure is harmful and must be rectified immediately.

Coolant Temperature Warning Light

The coolant temperature warning light, generally a thermometer or engine overheating insignia, signals high engine temperatures. This indicates engine overheating, which can be dangerous if ignored. When this light appears, stop and turn off the car. After engine cooling, check and add coolant. If coolant or hose damage is found, get professional help.


Warning lights are essential for vehicle safety and performance. Each light indicates possible problems, allowing you to remedy them early. Knowing these signs and how to behave may avoid minor issues from becoming major ones. Your car’s owner’s manual or a mechanic might provide specific instructions. Paying attention to these warning signs and responding swiftly can improve driving safety.
