How to use automatic transmission? What to look out for?

I think it's just acceleration and deceleration, but don't suddenly increase it too quickly, it may cause damage.

In fact, this addition and subtraction still has a very big effect, because in this way, you can make this speed more appropriate.

It is to decide whether to add or subtract according to the road conditions at the time, and you must be careful not to do what you want.

Generally, the plus sign on the automatic transmission is used when overtaking.

"d" is the abbreviation of drive (drive, forward) in English, which means forward gear. In this gear, the transmission will automatically shift gears based on the speed and throttle to keep the vehicle at the most economical speed. D gear is adapted to most road conditions, so it is often said that "automatic D gear goes around the world".

This is the automatic manual mode, which is manual upshift and downshift. To protect the transmission, manual upshifts and downshifts are also restricted. In manual upward movement, the transmission can add one gear only when the engine reaches a maximum speed that matches the position of the gear; Conversely, during manual downshifting, the transmission reduces one gear without overspeeding.

For example, if you want to manually downshift your car to first gear in fifth gear, it won't do it either. It will automatically downshift to first gear only when the speed reaches the speed range of the first gear.

Up and down slopes. When going uphill, you can shift the gear to a low gear below 3rd gear to maintain more torque, making it easier to go uphill. When going downhill,If the slope is steep or the downhill is long, you must continuously press the brakes in automatic mode to slow down, you can manually switch to first or second gear, and use the engine brake to control the speed of the car to avoid brake pad overheating and brake failure caused by frequent braking application.

Accelerate to overtake. It is best not to use the big foot throttle in high gear directly for fast overtaking, but to downshift first, manually downshift one gear, and use low gear, high speed and high torque to achieve fast overtaking. Rain and snow roads.

Friction on rainy and snowy roads is reduced, and the automatic transmission starts in first gear by default. Due to the high torque of the first gear, too much oil is easy to slip. At this point, use the manual mode to switch to second gear, which will reduce the possibility of slippage.

Crowded sections. In congested road sections, the vehicle stops at a low speed, and manually switching to a low speed can avoid repeated automatic gear shifts, making it more convenient for the vehicle to stop repeatedly.

M is the initial letter of manual, which means to enter the mode of manual shifting.

Generally, the M-gear transmission will also have a + and -sign next to it, and the gear can be shifted by pushing the gear lever forward and backward or by using the steering wheel paddles. However, unlike manual transmission, there is no need to release the throttle when changing gears, just add or subtract directly. But there are also restrictions on shifting, and it will only work if you do it within the safety parameters, for example, it is impossible to go up to 6th gear if you want to 50 yards or 100 yards to go down to 1st gear.

Automatic transmission cars are purchased by many consumers because of their simple and practical operation, and now many friends who buy cars are more inclined to automatic transmission cars. The advantages in congested urban areas are still relatively obvious, and it is also easier for novice friends to get started. However, it may be a little unfamiliar to those who are new to automatic transmission cars.

M+ M - That's the automatic transmission box with a manual automatic.

This means that it can be changed automatically or manually, that is, if you shift the gear lever to the middle of the M+ M- symbol.

Push the gear lever to M+ is to add a gear.

If it is to the M-push lever, it is to reduce one gear.

It is a manual automatic transmission, which belongs to a kind of automatic transmission, but on the basis of automatic transmission, the function of manual gear change is added, and the two are not much different in nature.

As shown in the figure below, the gear is first pulled down and hooked"d' gear, then push the gear lever to the left until"m/s"When you need to increase or decrease the gear, push the gear lever forward to downshift, and pull back to upshift. Note that when your vehicle speed and engine speed are not as required, you will not be able to move up the gear, and your every step must be allowed by the transmission control unit. In manual mode, when the speed is low, the gearbox will downshift you but will not actively upshift for you.

Dial back to the right to resume the automatic mode, manual and automatic can be switched at any time, no brake is required, and the throttle can not be loosened.

Grade 8 Physics: Direction of friction between the front and rear wheels of a bicycle, with the front wheel facing backwards and the rear wheels facing forward.

AT is automatic.

The MT is a manual transmission.

If it's which m+ m- you're talking about

That should be a hand-integrated car, that is, it can automatically shift, or manually, that is to say, if you change the gear lever to the middle of the M+ M- symbol, you can add a gear to the M+ push gear lever, if it is to the M-push gear lever, it is to reduce a gear, push it is a gear, if you want to continuously add or decrease the gear, you have to push it, come back, and push it again.

In fact, it is an increase and a downshift. If you want to be proficient, you still need to practice!

It's an automatic transmission box with a manual automatic.

Moving from the D level to the manual gear, M+ is the upshift, and the M- is the downshift (the automatic gear sets several speed ratios to simulate the manual gear), which is set to adapt to the personnel who like to operate.

Hand automatic, m manual mode.

M+ upshift, M- downshift.

Push next to the D gear, push + is to increase the gear, to push - is to reduce the gear, but it is also limited by the speed of the generator, generally around 2000 rpm can be added, try it. Hope it helps!

It's relatively long! With myself and my own Audi car as a model!

First of all, it should be dialed in gear"+ ""-"In between, it can be called a vacancy! It's next to the D file!

Dial into"+ ""-"In between, activate the paddle shifters behind the steering wheel at the same time.

If you want to increase the gear, go for it"+ "Push it and he'll automatically get back into place! The current gear will be displayed on the display!

Paddle shifters, that is"+ "The paddle is pressed to achieve the upshift,"-"The paddle is downshifted!

However, my car is 7 front speeds, so I don't think that manual gear increase or decrease is of practical significance!!

It's troublesome!!

+ is to add a gear, - is to subtract a gear, get it friend?

Generally, the gearboxes of these models are manual transmissions!

It's fun to be in one. See how you use it.

The automatic transmission with + and - is manual and self-integrated, dialing to + is to increase gear, and dialing to - is to downshift.

That's what it means to be a manual one, and it's the manual mode that can be manually upshifted, and if you slow down, the manual mode will automatically downshift.

+ and - is a manual automatic gearbox, + is to add a gear, minus is to reduce a gear.

Hello, his symbol means that we hand shout the upshift and downshift of the pin action pattern. The plus sign represents our upshift, and the minus sign represents a general gear of our vehicle, which can be shifted after the Zhengyou vehicle is finished driving during normal use.

D is the forward of the automatic transmission.

In gear, plugging D is forward, and then the driver does not need to turn off the gearbox.

Well, many automatic transmissions now also add "manual function" + and - which means "upshift" and "downshift".

In fact, the automatic transmission is not without gears, but the computer controls the automatic shift. In manual mode, the driver is given the shift operation. For example, the gearbox starts in 1st gear by default, and if you push the gear lever (in the direction of +), the car will go up to 2nd gear. Vice versa.

d+/d-。This is manual mode, and the gear lever can be held down while driving in D gear.

Push the D+ D-position to the right, and the gear lever is between D+ and D-, and then press and hold forward (D+) or pull back (D-) once, which means that one gear is increased or lowered (the instrument panel has a digital display gear), which can be continuously increased or decreased. Unlike some cars, the gear lever automatically springs back to the middle position between D+ and D- after each upshift or decrease, and the gear lever does not stay in the D+ and D- positions. When you want to return to Auto mode, just press and hold the gear lever and push it directly to the left to the D gear (the instrument panel will automatically switch to Auto mode).

This is a manual automatic transmission, D gear is forward, + and - is switched to manual mode, when the gear is in D gear, you can hang the gear to the right, and then it is the manual mode, which is equivalent to opening a manual gear, and then going up is to add gear, down to downshift.

What does it mean to lower the gear low on a mid-range car? Some of the off-road is not called the urban off-road class, and some are not.

What does the plus or minus mean in car D? After reading it, you know?

The gear after moving from D to M is the gear you were in before you switched to D gear. After entering the M gear, continue to refuel, the engine speed increases, the gear remains unchanged, and the speed is increased to dial M+; Need more output or reduced speed driving dial m-; After continuous deceleration to a stop, it automatically returns to 1st gear.

According to your question, your car should be self-integrated, and pushing from D gear to M is actually changing to manual transmission mode, which is equivalent to driving a manual transmission car. Therefore, depending on the speed you are driving and the engine speed, you need to decide whether to choose M+ or M-.

Landlord, what kind of car did you come from? Generally, automatic transmission cars do not have M gear, only N gear.

The N gear is equivalent to neutral, above the D gear.

M gear is manual gear, and M+M- is plus or minus gear.

How to shift between automatic transmissions, how to step on the brake accelerator is a headache for many novice drivers, Xiao Buan has received a question of "whether the automatic transmission car can be directly changed from D gear to S gear while driving", and today Xiao Buan will answer it for you.

Can an automatic car change from D to S while driving?

Xiao Dian's answer is: Yes. When the car is driving, it can switch between any gears except P and R gears, but pay attention to the throttle must be released when switching, otherwise there will be losses to the engine and gearbox.

How do I switch between automatic gears?

1. P to R, R to P should be locked by the gear and braked.

2. R to N do not need to press the gear lock and brake.

3. From N to R, press the gear lock and brake.

4. From n to D, press the gear lock and brake.

5. From D to S, press the gear lock, no loose oil and no brake.

6. S to D can be pushed directly, no loose oil and no brakes.

7, d to d (+, no loose oil, no brakes, no need to press the gear lock, direct dial. After pushing it over, it is directly the gear corresponding to the D gear.

8, d (+, to d do not need loose oil and no brake, no need to press the gear lock, direct dial. After dialing it back, it will change to the appropriate gear in D gear according to the speed, torque, etc. That is to say, the 3rd gear of d (+, 5000 rpm, may be cut to d is 5th gear 2000 rpm.

9, d (+, plus and minus gears do not need to press the gear lock, do not need loose oil and do not brake.

Xiao Bu has something to say: Xiao Buan has also received the question of whether the automatic transmission car is ignition in D gear. Xiao Dian explains here: only P and N can be ignited, but any gear can be turned off, how to turn off the flame correctly, Xiao Dian will talk to you later.

How to drive an automatic vehicle:

1. When the gear knob position is in P (or N) gear, the key is on the car;

2. When moving gear D forward gear or R backward gear, you must press the brake (brake); Otherwise, you can't move;

4. When you need to stop, directly step on the brake (brake); The body stopped;

5. Stop for a short time and directly press the brake (brake); For a long time (more than 2 minutes), it is best to move the gear in N gear and lift the brake (brake); Use the handbrake to stop the car;

6. In the gear, the letter P is parking (parking), R is reversing, N is neutral, and D is forward; If it is a manual automatic transmission + is to increase one gear - it is to lower one gear;

7. Downhill and uphill can always use D gear, and use the brake and accelerator to control the speed.

8. When waiting for the red light or stopping production for a short time, the gear is hung in D gear and then the brake is pressed; If the time is slightly longer, more than 2 minutes, it is better to move the gear to N gear and lift the brake (brake); Use the handbrake to stop the car;

Some friends who have just started to contact automatic transmission models ask: If you keep stepping on the brakes when the production is out of production for a long time, will it be a great damage to the vehicle? The actual automatic transmission model has been designed with this factor in mind, and there is no big mark.

System; After a long time, it is just a slight increase in fuel consumption and a slight wear of brakes; On the contrary, the replacement is frequent, and the fuel consumption and brakes are saved, but it will increase the wear and tear of the planetary gears inside the automatic transmission; So chosen.

A relatively reasonable time that takes into account both, limited to two minutes, and that's it.
