How to use the plus and minus in D gear: Depress the brake pedal and press the one-touch start button; Place the automatic gear lever in the D position to enter manual mode; Push the gear lever forward once to increase one gear; Pull the gear lever backward once to decrease one gear. D gear is a common gear in automatic transmission models, usually located in the middle-rear position of the gear console, behind the N gear, designed to automatically select gears when the car is moving forward. D gear is a forward gear, but forward gears are not limited to D gear, they also include M gear, S gear, L gear, and numerically labeled restricted gears such as 1st, 2nd, and 3rd gears.

I've been driving automatic transmission cars for over 20 years, often taking long trips in mountainous areas. The D-gear plus/minus function is quite practical, especially when going downhill on winding mountain roads. Gently pushing it to the minus sign for downshifting provides noticeable engine braking, preventing wheel slippage without constantly stepping on the brakes. I also use this trick when overtaking on flat roads - downshifting gives quicker acceleration and more stable overtaking, but be careful not to let the RPM reach the red zone to avoid engine damage. It's best to read the manual first to familiarize yourself with the operation location, usually near the gear lever or behind the steering wheel. This function adds driving pleasure and saves some brake pads, but beginners should practice in an open area to get familiar with the feeling before hitting the road.

As a novice who bought a car less than a year ago, I found that the D-gear plus/minus design is actually very convenient to operate. Just gently push the small gear lever toward the minus sign in D-gear mode to downshift, and the power instantly kicks in for quick acceleration—really responsive when overtaking. Shifting toward the plus sign upshifts to lower the RPM and save some fuel, but don’t overuse this mode since manual shifting isn’t easy to master and may lead to RPM control issues. My friend took me for a few track experiences where the RPM surged to 4000, delivering intense acceleration, but the return trip showed slightly higher fuel consumption. Before using it, make sure the car is in manual mode to avoid accidental operations.

I usually use this D-gear shift function in my driving habits, which mainly involves simply pushing or pulling the gear lever to upshift with the '+' sign or downshift with the '-' sign to help control the vehicle speed. For example, when going uphill on the highway, pushing to downshift can prevent stalling. It's also occasionally used in congested urban areas, but don't overuse it—keeping the engine speed around 2000 RPM is healthier. This design allows automatic transmissions to experience the fun of manual shifting, but remember to switch back to D-gear automatic mode after use.

I've been driving my kids to and from school every day for ten years, rarely engaging in performance driving. However, during heavy snow, I switch to D-gear manual mode and use the downshift function to reduce gears, controlling the speed on slippery roads through engine braking to avoid skidding from sudden braking. The operation involves gently pushing the gear lever to the plus/minus symbol position while driving, which is easy to get used to. Initially, shifting gears at too low speeds might cause jerking, but a few practice runs will smooth it out. The key is to flexibly switch modes based on road conditions, avoiding unnecessary excitement that could increase fuel consumption and wear.

I understand that the D gear plus/minus is mainly for manual intervention in shifting. Pushing to the minus sign downshifts to increase torque and enhance power, which is suitable for climbing steep slopes or quick overtaking. The plus sign upshifts to reduce RPM for smoother driving, which is better on flat roads. When using it, observe the tachometer on the dashboard to ensure it doesn't exceed 3000 RPM, as going beyond that is bad for the engine, increasing wear and potentially damaging parts over time. This feature is quite , but remember it only works in manual mode. It's recommended to regularly check the gear linkage wires to prevent aging and ensure safe driving.
