What does the red P light on the dashboard mean?

[BraydenLynn]

The red P light indicates that the handbrake is not fully released. Here is relevant information about the handbrake: 1. Principle: The handbrake, professionally referred to as an auxiliary brake, operates differently from the main braking system. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. 2. Consequences of long-term use: Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness and increase the handbrake's travel distance. 3. Spring: The spring works in conjunction with the handbrake. When the handbrake is engaged, the spring is stretched; when released, the spring returns to its original length. With prolonged use, the spring may also undergo corresponding deformation.
