Shifting to P gear requires stepping on the brake. When the gear is shifted to P, there is a locking gear in the automatic transmission that locks the gearbox. Therefore, any movement of the wheels while in P gear can easily cause damage to the locking gear and even severely affect the transmission. The following is a related introduction about the P gear: Connection between the vehicle and mechanical structure: Generally, many modern cars have protective devices that require stepping on the brake to operate during ignition and gear shifting. For keyless start vehicles, pressing the start button without stepping on the brake will only turn on the power, and stepping on the brake is necessary to successfully start the car. Some cars require stepping on the brake to shift out of P gear to start the vehicle, which is determined by the vehicle's mechanical structure. Function of P gear: In automatic transmission models, to prevent the driver from accidentally shifting out of P gear into other gears, causing sudden movement of the vehicle that could harm the vehicle and personnel, automotive engineers have designed a P gear lock on the gear lever. This lock prevents the P gear from automatically disengaging or being shifted out without the driver's permission. The lock will only release under certain conditions.

When I first started driving, my instructor always emphasized stepping on the foot brake before shifting to P, so I developed this habit. When parking, first press the brake to bring the car to a complete stop, engage the handbrake or electronic foot brake to secure the wheels, and only shift into P after confirming the car is stationary. Especially on slopes, if you shift to P without stepping on the foot brake, the transmission's locking mechanism will bear excessive pressure, which may lead to wear or failure over time. You might skip steps on flat ground, but for safety, it's best to follow the procedure every time to prevent rollaway accidents. The vehicle manual also recommends this sequence to protect the transmission and extend its service life. Spending an extra two seconds can save you from major repairs.

As someone who frequently maintains vehicles, I believe stepping on the foot brake before shifting to P gear is essential. The P gear is designed to lock the transmission gears. If the wheels aren't secured with the foot brake first, the vehicle's entire weight rests on the transmission, which over time could cause the gears to jam or get damaged. The simple steps during operation are: after coming to a complete stop, step on the foot brake, pull the handbrake button, and then shift to P gear. Some new cars come with automatic brake assistance, but manual operation is more reliable. Forgetting this step when stopping at an intersection could lead to the car sliding and causing a rear-end collision. The cost of repairing a transmission isn't cheap, so it's best to cultivate good habits from daily practice.

Driving safety is paramount, and engaging the parking brake is essential when shifting to P (Park). This prevents the vehicle from rolling, especially on slopes or during rainy conditions when the road is slippery. By securing the vehicle with the parking brake before shifting gears, you reduce strain on the transmission and minimize the risk of damage. Neglecting this habit can lead to minor issues like wheel slippage causing injury, or worse, rear-end collisions. Develop a routine of stabilizing the vehicle before taking action—protecting both yourself and your car. Remember the simple principle: safety comes first, no exceptions.

I pay attention to vehicle protection, so I always step on the parking brake before shifting to P gear. Otherwise, if the vehicle is parked on a slope, the transmission gears will be under excessive pressure, which may cause abnormal noises or malfunctions over time. The correct procedure is to stop the car, press the brake pedal, pull the parking brake button to lock the wheels, and finally shift to P gear to distribute the weight. The operation is the same for different vehicles, and developing this habit can save repair costs and extend the lifespan of parts. Regularly maintain and check the brake system to ensure it is responsive and reliable.

During driving lessons, the instructor always repeats: engage the parking brake when shifting to P gear. The steps are simple: stop the car by pressing the brake pedal to stabilize the vehicle, pull up the handbrake or press the foot brake button to secure the wheels, and confirm the car is stationary before shifting to P gear. This prevents additional pressure on the transmission and enhances safety by avoiding accidental rolling. A common oversight is rushing to shift gears and forgetting this step. Practice more to develop a natural habit, paying extra attention on slopes while being mindful even on flat ground.
