There are six gears on a general automatic car, from top to bottom: P, R, N, D, 2, L.
P – Parking. When you don't use it, the gear is there, and the wheels are mechanically locked to prevent them from slipping.
R – Peverse Gear, reverse. Used when reversing.
n - none, neutral. Use this gear when stopping temporarily (e.g. at a red light). Note that this gear indicates neutral, and to prevent the vehicle from slipping on slopes, be sure to apply the brakes.
D - Forward gear, also known as drive gear. Needless to say, this gear is used when moving forward.
2 - low gear, when going up a large slope, or when starting on a relatively inclined slope, you can use this gear to start and move forward. The principle is that by hanging the gear here, you can limit the gear of the car to automatically switch only in the low gear (equivalent to the first and second gears of the manual transmission car) to ensure that the car gets the maximum forward momentum.
L-Low, low gear. When going downhill or down a long-distance slope, hang the gear here, which can limit the gear of the car to automatically only be in the lowest gear (equivalent to the first gear of the manual transmission car), which can make the car use engine power to brake when going downhill, and the driver does not need to step on the brakes for a long time to cause the brake pads to overheat and cause danger.
OD---OD gear is overdrive, which is used when driving at high speed to achieve the purpose of fuel saving. Once you understand the functions of each gear of the car's automatic wave, you can enjoy driving a car equipped with automatic wave.
Just push into 1st gear.
The gear lever is back.
Then the brakes were originally in 3rd gear and dropped to 1st gear.
It's simple.

The manual automatic car can be directly switched to manual mode while driving。When using the manual mode, pay attention to the information on the instrument panel, which will show the gear position in the manual mode.
In order to achieve fuel economy and a smooth ride, automatic transmissions usually tend to use the highest gear possible, but on city roads there is often heavy traffic and slower speeds, requiring frequent acceleration and braking.
Every time you accelerate, the gearbox will be lowered to a low gear, and in order to be stable when resuming the oil, the gearbox will automatically upshift, so that frequent gear changes are not only not conducive to smooth driving, but also affect the life of the gearbox for a long time.

For a manual automatic car, when you switch from automatic transmission to manual transmission, you only need to flip the gear lever to the right while driving.
Manual automatic car refers to the assembly of the use of "manual automatic" gearbox car, "manual automatic" transmission is a form of transmission that combines manual shift and automatic shift two modes.
-
Automatic Transmission: A shifting method that combines manual and automatic shifting of the car.
-
The car that can be directly shifted is the same as the car with a manual transmission, but without the operation of the clutch.
-
The manual automatic transmission can be divided into the following situations to operate: 1. When going up a steep slope: the manual mode of the automatic manual transmission should be used to limit the gear to 1 gear to cope with frequent slope starts.
Doing so also protects the gearbox. 2. When accelerating to overtake: Before overtaking, if the transmission is in high gear, the first thing we need to do is downshift, not continue to step on the accelerator deeply.
By using the manual mode of the transmission to quickly downshift, the vehicle can use the source to help the high torque in the low gear to instantly increase the speed and complete the overtaking maneuver faster. The downshift mentioned here does not mean that you must drop to a low gear within 3rd gear before overtaking, but that you can get enough torque to get the torque you need to speed up by lowering one gear on the current gear and keeping the engine speed at about 2500rpm.

The automatic mode of the automatic manual car changes the same as that of a regular automatic car. In manual mode, you need to switch to manual mode to shift, the manual mode of switching is in D gear, to the right, in manual mode is manual upshift, automatic downshift operation mode, if you want to raise the speed gear in manual mode, you need to break the shift handle forward, and if you want to reduce the speed gear, you don't need to operate, after the speed is down, it will automatically downshift.
Precautions for manual driving:
1. When starting, try your best to put the gear in P parking gear and N neutral gear, and then step on the brakes and start the car. If the car is started in other gears, it is easy to wear out the transmission due to the degree of overgearing;
2. When the vehicle starts, it is put into D gear after stepping on the brake, and then gently lifting the clutch, and the vehicle can be on the accelerator after walking out of a few meters. On the smooth ground of the road, you can always hang D gear to move forward, and try your best to prevent slamming on the accelerator, otherwise you will add too much fuel;
3. When it hits the ground of climbing, change to the climbing gear as much as possible, which not only has strong power output, but also prevents the engine from rotating hard;
4. The manual automatic transmission is very useful in traffic jams, because if it is only hung in D gear, traffic jam stop-and-go, the gear will jump back and forth in gear, which will accelerate the wear and tear of the transmission, so in the traffic jam road conditions, immediately use the manual blind Jane to change the speed is quite good, if the speed is up and down 20 kilometers, you can hang the gear in 2nd gear; More than 30 kilometers are hung in 3rd gear. It can also be hung in the S limit gear to limit gear jumping;
5. In automatic transmission, when encountering a downhill road section, you must not hang someone n neutral, don't think that this saves trouser oil, which will only backfire, and will affect the lubricating oil of the oil pump, which will cause great damage to the transmission;
6. When the vehicle is parked, it is best to put the car gear in the P gear and turn off the ignition and pull out the key. In addition, when parking on uneven ground, the handbrake should be tightened to turn off, otherwise the vehicle will move back and forth after the ignition, which will have an impact on the gears of the transmission, which will damage the transmission.

Automatic, manually operated cars can shift from D to M while driving. To change gears, simply flick the paddle shifters on the Shift Trail lever or steering wheel or press the shift button. When driving, you need to flexibly control the gear through speed, which can not only save fuel consumption, but also quickly overtake.
Accessory: When you need to switch to manual mode:
1. Long steep slope:
When a vehicle climbs a steep hill, it needs the engine to provide enough power. The driver can switch to manual mode and start in first gear. The vehicle can output stable power through gear limits.
2.When walking down a long slope:
When the vehicle is going downhill, the manual mode can be changed. Manual mode allows the transmission to be restricted to a low gear, and the speed is controlled by the engine without having to apply the brakes for a long time. It can also prevent the brakes from overheating when the vehicle is going downhill, affecting the braking performance of the vehicle, and can make the speed control of the vehicle simpler.
3.Switch to manual mode when accelerating to overtake:
If you want to save time when overtaking, you can switch the gear to manual mode, downshift first, and the vehicle will instantly accelerate with high torque in low gear, so that the overtaking operation can be completed in less time. When downshifting, you don't have to downgrade to within three gears, which is the previous gear of the current gear, and you can get more torque by keeping the engine at around 2500rpm.
4.Running winding mountain roads:
Manual mode can be used on some roads with more curves, so speed control is very important. Speed is difficult to control due to the inability to control the throttle at ideal conditions during cornering. After switching to manual mode, you can downshift in corners and control the speed by gear to ensure the stability of the speed and driving safety.
However, it is necessary to be flexible in the use of manual mode and avoid using manual mode in unfamiliar situations.

General operation method of manual transmission:
1. After the vehicle is started, during driving, switch the gearbox shift lever to M gear or S gear (or the gear with +- mark), and switch the gear by toggling the gear lever forward and backward.
2. The vehicle is in the starting state (idle or driving) can be switched to manual mode for shift operation in the above way, if you need to switch back to D gear during driving, (automatic mode) only need to directly switch the gear lever from the position of manual mode back to D gear. (Switch gears horizontally to the right or left).
What are the contraindications of shifting gears in a manual car?
1. It is strictly forbidden to look down at the gear lever, and always pay attention to the road conditions ahead.
2. It is forbidden to empty the throttle when downshifting to prevent the flameout.
3. Do not drive at low speed for a long time, which will increase the wear and tear of the car.
4. It is forbidden to skip the gear, and the clutch must be stepped on to the end.
Of course, it's one, 800 yuan of maintenance**, it shouldn't be after-sales maintenance, 800 yuan is still acceptable.
