What is the introduction to the gears of Dongfeng Nissan automatic transmission cars?

Dongfeng Nissan automatic transmission gear introduction: 1. P is the parking gear: When the car is not in use, the gear is in this position; 2. R is the reverse gear: The car can only be shifted into R gear after coming to a complete stop and pressing the brake pedal; 3. N is the neutral gear: N gear is used for temporary stops such as at red lights; 4. D is the drive gear: When shifted into this gear, the driver's task is to control the throttle and brake; 5. S indicates sport mode, where the transmission can shift freely in this gear. Taking the Nissan Teana as an example, the car's dimensions are 4901mm in length, 1850mm in width, and 1447mm in height, with a wheelbase of 2825mm. The Teana features front-wheel drive, with a front suspension type of MacPherson independent suspension and a rear suspension type of multi-link independent suspension.
When driving daily, the automatic transmission gears of Dongfeng Nissan are actually very simple and easy to use. The P gear is the parking gear; after parking, always engage this gear to ensure the car doesn't slide, especially for safety on slopes. The R gear is the reverse gear; before reversing, make sure the car has completely stopped before engaging it, then lightly press the accelerator to slowly back up. The N gear is the neutral gear, which can be engaged during short stops like waiting at a red light, but don't rely on it—just stay in D gear and hold the brake. The D gear is the driving gear, which I usually use for forward movement, as the transmission shifts automatically and smoothly. Some models also have a B gear or manual mode; engaging it downhill can use engine braking to reduce brake wear. When starting, shift from P to D while pressing the brake to move forward, and take your time with gear changes to avoid damaging the transmission. While driving, pay attention to the gear display on the dashboard to prevent accidents from incorrect gear selection. Develop the habit of checking frequently—safe driving is the most important.
From a safe driving perspective, the automatic gear settings of Dongfeng Nissan place great emphasis on safety. The P (Park) gear locks the transmission and must be properly engaged when parking to prevent vehicle movement. Before shifting to R (Reverse) gear, ensure the vehicle is completely stopped, press the brake pedal firmly, and check the rear clearly to avoid collision accidents. The N (Neutral) gear is used for towing or moving the vehicle in case of a malfunction, but never engage it while driving to prevent loss of control. D (Drive) gear is for forward movement, ensuring smooth driving. The key lies in the gear shifting sequence: for example, when starting, you must be in P gear with the brake pedal pressed before shifting to D, and when parking, always engage P gear. Avoid improper switching, such as shifting directly from D to R, as this can damage components or cause hazards. Incorrect operation may lead to transmission failure and increase risk costs. Develop the habit of applying the handbrake before shifting to P when parking to protect both yourself and the vehicle.
In terms of technical principles, each gear in Dongfeng Nissan's automatic transmission has its specific purpose. The P gear mechanically locks the wheels to secure the vehicle. The R gear reverses the power for backing up. The N gear disconnects the transmission with no power output. The D gear is for forward movement with automatic shifting. Some models feature a manual-automatic hybrid like the S gear for high RPM mode. Operation is simple: computer control ensures smoothness, and the driver only needs to shift as required. Proper usage extends lifespan and reduces repairs.
