The 'a' under the parking brake 'p' stands for the auto-hold system. Introduction to Auto-Hold: Auto-Hold, also known as AUTO-HOLD, refers to an automatic braking function. When activated, such as when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of manual or electronic parking brakes. For automatic transmission models, it also reduces the need for frequent shifting between D to N or D to P. Working Principle of Auto-Hold: The AUTO-HOLD function provides precise braking force through a slope sensor controlled by a unit. During startup, the parking control unit calculates information from sensors such as clutch distance, clutch engagement speed, and throttle pedal. When the driving force exceeds the running resistance, the parking brake is automatically released, ensuring a smooth start.
