What does the P with a slash mean as a warning light?

[VictoriaDella]

The dashboard P light with a slash indicates a parking brake malfunction. In this case, you should promptly visit a 4S shop or repair shop for maintenance. The illuminated P light on the dashboard shows that the electronic parking brake is in the activated state. The parking system is divided into electronic parking brakes and automatic parking. The application of mechanical control electronics is becoming increasingly widespread, and the parking brake has evolved from the traditional lever handbrake to an electronic parking brake button. The function of the electronic parking brake remains unchanged, only the control method has shifted from the previous mechanical handbrake lever to an electronic button. Automatic parking is a function of automatic braking. After activating this function, it simplifies operations by avoiding the use of the handbrake or electronic parking brake, and for automatic transmission models, it eliminates the need for frequent switching between D to N and D to P. The functions of the handbrake are: pulling up the handbrake when parking keeps the vehicle stationary and prevents it from rolling downhill; pulling up the handbrake while turning during driving can create a drifting effect; in emergencies, the handbrake can be used as a brake. Precautions for using the handbrake: avoid pulling it too tight to prevent system damage; avoid parking with the handbrake on long slopes; do not pull the handbrake while driving at high speeds; release the handbrake before starting the car.

I encountered this slashed P light on my dashboard the other day while driving and initially thought it was a system malfunction. Actually, it's the brake system warning light, primarily alerting that the parking brake isn't fully released or there's an issue with the braking system. I remember once when I didn't engage the parking brake properly, this light flashed, and pressing the parking brake button again turned it off. If the light stays on after properly releasing the parking brake, it might indicate low brake fluid or excessively worn brake pads - my old car once experienced brake fluid leakage. It's crucial to take this dashboard warning seriously; I always pull over immediately to check since it's directly related to braking performance. My advice is to first check the parking brake status yourself, and if the issue persists, contact a professional mechanic right away.

Last week when I was helping my neighbor check his car, he pointed at this P light with a slash and asked me about it. The full name of this indicator is the Brake System Warning Light, and the most common reason for it to illuminate is when the handbrake isn't fully released. That time, my neighbor's handbrake got stuck in a middle position while parking, causing the light to stay on. We had to press the handbrake switch again to turn it off. If the light remains on after ruling out handbrake issues, it might indicate low brake fluid or a malfunctioning ABS pump. Once during a long drive, this light came on, and after pulling over, I found the brake fluid reservoir level had dropped below the minimum mark. Now I've developed a habit of glancing at the dashboard before every trip, especially before highway drives - it's crucial to ensure all warning lights are off for safety.

That P light with a slash is the parking brake indicator light. It comes on mainly for two reasons: either the handbrake isn't fully released or there's a brake system malfunction. I've experienced it several times myself - the light always comes on when I forget to release the handbrake, and the car becomes particularly hard to drive. Once while going downhill on a mountain road, it suddenly lit up, scaring me into immediately finding level ground to stop and check. Turned out the brake fluid was below the minimum level, so I rushed to the shop for a top-up. You must never ignore this light being on - at best it could mean the handbrake isn't released, damaging the brake discs, at worst it could lead to brake failure. Now I regularly check the brake fluid level and have developed the habit of pulling the handbrake all the way, so the light rarely comes on anymore.

Last time while driving my kid to school, the P light with a slash suddenly illuminated, so I immediately pulled over. This light is technically called the brake warning light, with root causes falling into two categories: physical issues and system issues. Physically, it's often due to the parking brake lever not being fully depressed - my SUV once triggered this light because the handbrake got stuck in position. On the system side, it involves insufficient brake fluid or a faulty distribution valve. The mechanic mentioned excessive brake pad wear can also trigger it. I always start the car ten minutes early to check the dashboard, paying special attention to this light's status. Once after maintenance, the handbrake sensor wasn't reset properly, causing the light to illuminate unnecessarily, which required readjustment to fix. My advice: if the light stays on, first test brake responsiveness, and if abnormal, head straight to the workshop.
