What does it mean when the dashboard P light is on with a slash?

The dashboard P light being on with a slash indicates a malfunction in the handbrake. In this case, you should promptly take your vehicle to a 4S shop or repair shop for maintenance. The functions of the handbrake are: 1. When parking, pulling up the handbrake keeps the vehicle stationary, preventing it from rolling downhill; 2. While driving, pulling up the handbrake during a turn can create a drifting effect; 3. In emergency situations, the handbrake can be used as a brake. Precautions for using the handbrake: 1. Avoid pulling it too tight to prevent system damage; 2. Avoid using the handbrake for long-term parking on slopes; 3. Do not pull the handbrake while driving at high speeds; 4. Release the handbrake before starting the car.
This P light with a slash, I reckon from a technical standpoint, usually indicates an issue with your parking brake system. In many vehicles, P stands for the parking indicator light. If a slash appears next to it, it means the handbrake or electronic parking brake hasn't fully released or there's a malfunction. Common causes include a stuck handbrake cable, faulty sensor, or low brake fluid level, which triggers an abnormal signal in the system. Sometimes, an electronic control module failure can also cause this, especially in automatic transmission models. Once this light comes on, you might feel increased resistance or hear strange noises while driving, as it restricts the braking function. I recommend safely pulling over immediately to check if the handbrake is fully released and then popping the hood to inspect the brake fluid reservoir level. If the issue persists, it's best to have a professional mechanic scan for trouble codes using diagnostic tools to avoid prolonged wear on brake components and higher repair costs.
