How to Use the M+ and M- in an Automatic Transmission?
3 Answers
Automatic transmission M+ and M- usage methods are as follows: 1. Overtaking: Use the "M-" gear to lower the gear, which provides high torque, allowing the car to accelerate quickly in a short time. 2. Uphill: On uphill sections, use "M-" as the lower gear provides stronger engine power. 3. Downhill: You can use "M+" to adjust the gear to 2-3, utilizing the engine's braking effect to slow the vehicle without relying entirely on the brakes, thereby enhancing driving safety. 4. Highway: On highways, manually use "M+" to shift to a higher gear, maintaining a speed of 80-100km/h for better fuel efficiency. 5. Snowy/Icy Roads: Adjust the gear to 2 using "M+" to reduce wheel slippage.
The first time I drove an automatic car with manual mode, I was quite confused too, but I gradually got used to it. The operation is quite simple: after starting the car, push the gear lever to the position marked with 'M', or directly use the paddle shifters on the steering wheel. To upshift, press the '+' or push it upward; to downshift, press the '-' or push it downward. This way, the car won't shift gears automatically, and I have to control the gear level myself. Usually, when overtaking on the highway or climbing a slope, using the manual mode allows the engine to perform better and accelerate faster. When going downhill and worried about the speed being too high, downshifting to a lower gear can help slow the car down using engine braking, which is quite practical. At first, I was worried that pressing the wrong button might damage the car, but actually, the car has a protection function that prevents downshifting too low and harming the engine.
Manual mode is a fun feature of automatic transmissions, quite enjoyable to use. I rarely engage it during city driving, but it comes in handy for special situations. For instance, when needing a sudden acceleration to overtake, downshifting first to raise engine RPMs for instant power; or when descending a steep slope and worrying about brake overheating, downshifting helps slow the car more safely. Operation-wise, simply shift the gear lever to the dedicated M position—many cars also offer steering wheel-mounted paddle shifters for added convenience. Initially, I kept checking the instrument cluster to confirm gears due to unfamiliarity, but with practice, I learned to shift by feel. Remember to return to D (Drive) mode afterward to avoid affecting fuel efficiency. It's perfect for those seeking occasional driving excitement, especially when navigating mountain roads or heavy traffic, where the added sense of control brings reassurance.
