What does Corolla 3d gear mean?

Corolla's automatic gear has five gears: P (parking gear), R (reverse gear), N (neutral gear), D (forward gear) and M (manual gear). Before using P gear, the vehicle must come to a complete stop, otherwise the mechanical part of the automatic transmission will be damaged.

Corolla uses stepped gear, also called snake gear, which is also a very common automatic gear design, especially on Japanese cars. Its advantages and disadvantages are just the opposite of in-line type. The advantage is that it is not easy to shift gears, and the disadvantage is that the operation is not as smooth and direct as in-line operation. Each gear is introduced as follows: P (parking) gear P is the parking gear and the parking gear, which is the gear that the vehicle is engaged when it is parked for a long time. It uses the mechanical device in the gearbox to lock the rotating part of the car so that the car can't move. The correct operation method is to pull the hand brake first, and then shift into P gear.

However, it should be noted that P gear can only be used after the vehicle is completely stopped, otherwise the mechanical part of the automatic transmission will be damaged. In addition, the automatic gearbox is equipped with a neutral start switch, so that the vehicle can only be started in P or N gear, so as to avoid the sudden forward driving of the vehicle when other gears are started by mistake, which is prone to danger.

R (reverse) gear R is also called reverse gear, which is the gear that the vehicle is put into when it needs to reverse. When the shift lever is in the R position, the reverse oil circuit of the hydraulic system is connected, and the driving wheel rotates in the reverse direction, thus realizing reverse driving. When operating, you need to step on the brake and press the shift lock on the shift lever to move the shift lever to the R position. However, it should be noted that it is not allowed to forcibly shift into R gear when the vehicle has not stopped completely, otherwise the gearbox will be damaged.

N gear (neutral) N gear is neutral. I believe everyone should have a good understanding of this. The gear that needs to be put into when the vehicle stops for a short time without turning off the engine, such as waiting for a red light or traffic jam. After engaging in N gear, the power of the engine will not be output to the wheels, and the vehicle will not run when stepping on the accelerator.

D (drive) gear D is also called forward gear and drive gear. When the shift lever is set to D, the vehicle will automatically shift gears according to the throttle opening and speed data. This gear is suitable for general road driving, and the driver can control the speed only by controlling the accelerator pedal.

M (Manual) M refers to the manual mode of automatic manual transmission or the simulated manual mode of CVT transmission. When the shift lever is engaged in the M range, the shift will be completed manually by the driver. There will be a symbol of "+"or "-"near M gear, where "+"stands for upshift and "-"stands for downshift, or upshift or downshift can be made through the steering wheel shift paddle. The function of M gear is to increase the driving pleasure of vehicles and make them more comfortable to drive.
