What do the vehicle fault indicator lights mean?

[GavinMarie]

Vehicle fault indicator lights represent the following: 1. Steering system malfunction - the vehicle cannot steer at this time. Do not tow the vehicle forward as turning or similar maneuvers may cause danger; 2. Tire pressure monitoring system failure - there are two possible causes: either a punctured tire causing low pressure or overinflation causing excessive pressure, or forgetting to input new information after tire replacement so the system hasn't recognized it; 3. Cooling system malfunction - caused by insufficient coolant or non-functioning radiator fan; 4. Anti-lock braking system (ABS) failure - indicates ABS is currently inoperative. Electronic differential lock malfunction will also trigger the warning light. In emergencies, fully depressing the brake pedal may cause dangerous loss of control such as fishtailing or skidding.

I've been fixing cars for almost 20 years, and I see warning lights every day. Let's start with the most common yellow engine light—80% of the time it's an emissions issue or a sensor acting up. It won't leave you stranded immediately, but don't ignore it either. The red oil light is the most critical—stop the car right away if it comes on, or you risk total engine failure. Then there's the brake warning light—if it stays on even with the handbrake fully released, you might have a brake fluid leak or ABS trouble. The battery light, shaped like a little battery, means the alternator isn't charging, and you could stall mid-drive. The airbag light, showing a seated person, means your airbags might not deploy in a crash. If the red coolant temperature light comes on, shut off the engine immediately to avoid serious engine damage. My advice? Keep an eye on your dashboard—never drive with red lights on, and address yellow lights promptly.

Last week I just picked up my new car, and the salesperson gave me a crash course on warning lights. Those little icons on the dashboard aren't just for show—the red oil can light means you must stop immediately, as continuing to drive could destroy the engine. The yellow engine symbol usually indicates an exhaust system or sensor issue; you can still drive but shouldn't go far. The battery light looks like a small rectangle with plus and minus signs—if it's on, it means the charging system has failed. If the brake light comes on, first check the handbrake; if it's released and still lit, inspect the brake fluid immediately. The tire pressure light is a parenthesis with an exclamation mark, warning you of possible air leakage. If the temperature gauge turns red, pull over and shut off the engine while waiting for assistance. Oh, and the airbag light is that passenger-facing icon—if it's lit, it means crash protection is disabled. Remember: color determines urgency—red means danger, yellow means caution.

Yesterday while driving on the highway, the ABS light suddenly came on, which scared me into slowing down immediately. After years of driving, I've categorized warning lights into two types: red 'life-threatening' ones like the oil pressure and coolant temperature lights that require immediate stopping when illuminated, and yellow 'warning' lights such as the engine and tire pressure indicators that allow continued driving but need prompt attention. The ABS light, marked by three letters encircling an exclamation point, indicates anti-lock braking system failure, making braking prone to skidding especially in rainy conditions. The airbag light resembles a human silhouette icon - its malfunction reduces crash protection. The battery light signals charging system failure with potential for sudden power loss. Persistent brake light illumination may indicate hydraulic fluid leakage. Remember, the manual is more reliable than smartphone searches when encountering unfamiliar warning lights. Pre-trip vehicle checks before long journeys can prevent roadside panic.
