Turn off first then shift to P, or shift to P first then turn off?

Shift to P first, then turn off the engine. Here are the relevant details: 1. Introduction to N and P gears: These are provided for parking, where N gear is for temporary parking, and P gear is designed for long-term parking. There are considerations when using N gear for automatic transmission parking, as the car may roll if only N gear is engaged. Therefore, N gear should be used for short-term parking and only when the vehicle is completely stationary. 2. Automatic transmission gears: Driving an automatic transmission car only requires using P gear (Park), R gear (Reverse), N gear (Neutral), and D gear (Drive) to meet general driving needs. However, in some special driving conditions, other function gears may be needed.

I remember in my early days of driving, I was always confused about the parking sequence. Later, after learning safe driving practices, I realized the correct method is to shift into P (Park) before turning off the engine. This is because in the P position, the transmission is locked, ensuring the car stays securely parked, especially on slopes where it's less likely to roll. Once, in a hurry, I turned off the engine first, and the car slightly rolled, nearly hitting the curb—it gave me quite a scare. Since then, I've made it a habit to shift into P immediately after stopping, double-checking before shutting off the engine. This not only protects vehicle components but also prevents accidents. Developing good habits greatly enhances daily driving safety. Don't forget to combine it with engaging the parking brake for double security.

I understand the principles of automotive design. When parking an automatic transmission vehicle, you should first shift to P (Park) before turning off the engine. Engaging P activates the transmission's locking mechanism, which secures the output shaft and prevents movement. If you turn off the engine before shifting gears, the transmission remains in an operational state after engine shutdown, potentially subjecting it to unnecessary loads that could damage gears or drivetrain components. Consistently operating this way may increase maintenance costs over time. Good driving habits prolong vehicle lifespan, so it's recommended to follow this procedure every time you park.

As a regular car owner who drives an automatic SUV, I was initially unsure about the correct sequence. After consulting friends and the manual, the consensus was that it's best to shift into P (Park) first before turning off the engine. In practice, I always come to a complete stop, shift into P, and then turn off the ignition. This method makes the vehicle feel more stable with no strange noises or vibrations. After making this a habit, my car has gone three years without any transmission issues. I recommend everyone follow this simple procedure to avoid potential problems.
