This article discusses safety-related warning lights in modern vehicles. Warning indicators appear in two primary colors: red lights signal immediate attention needs, while amber lights indicate system malfunctions requiring prompt but less urgent service. Green and blue indicators typically show active systems like cruise control.
Brake Light Indicator
This red warning light activates when the parking brake is engaged or when brake fluid levels drop dangerously low. If the light appears while the parking brake is disengaged, "the vehicle should be checked out immediately." Towing is recommended. Low fluid levels may indicate worn brake components or leaks, compromising braking safety.
ABS Indicator Light
The amber ABS (Anti-Lock Braking System) light signals a malfunction in the anti-lock system. When illuminated, the ABS becomes disabled during emergency situations on slippery surfaces, though conventional brakes remain functional. If both ABS and brake lights appear together, immediate professional inspection is recommended.
Traction Control Light
This amber indicator displays a car with squiggly lines behind it. The system automatically applies braking to wheels spinning faster due to reduced traction. When this light activates, drivers should reduce speed.
Tire Pressure Monitoring System (TPMS)
The amber TPMS light features a triangle with an exclamation point. It indicates low tire pressure or system malfunctions. Check all tires, including the spare, and attempt a system reset. This feature helps prevent "the #1 breakdown on US Highways which is flat or blown out tires."
A forthcoming article will cover charging and starting system warning lights and fluid temperature indicators.
