Should I use M+ or M- when going uphill?

When going uphill, you need to use M-. Below are the reasons for using M- when going uphill and some precautions: Reasons for using M- when going uphill: The M gear in an automatic transmission car is the manual mode, where M+ is for upshifting and M- is for downshifting. When going uphill, downshifting is required, so you need to push the gear lever towards the M- direction. Engaging a lower gear when going uphill increases the torque at the wheels, which helps the car climb the slope smoothly. Precautions: Automatic transmissions have a protection mode. If the driver's operation is unreasonable after entering manual mode, the transmission will not execute the driver's commands. This is something to keep in mind.
I often drive on mountain roads, and when going uphill, I always choose to downshift (M-) to keep the engine RPM higher. This gives the car more power to climb and prevents it from feeling sluggish or struggling. I remember once on a steep mountain road, I had just upshifted (M+), and the car immediately slowed down, almost causing an accident. Since then, I've vowed to always downshift when going uphill. The principle is simple: downshifting allows the engine to produce more torque, which is ideal for low-speed, high-load situations. Upshifting, while more fuel-efficient, lacks sufficient power. Beginners might think upshifting is easier, but in practice, downshifting is safer and more reliable. After downshifting on a steep slope, the car responds more quickly, and you can better control speed and stability.
When driving uphill, safety is the top priority. I strongly recommend using the downshift (M-) method. The engine operates at higher RPMs in lower gears, providing sufficient power to prevent rolling back or stalling. Upshifting (M+) might be feasible on gentle slopes, but it reduces torque and increases risks. From personal experience, I always start with downshifting regardless of the steepness; only consider upshifting if the gradient eases. This approach not only protects the transmission but also prevents engine overexertion and reduces accident risks. Once it becomes a habit, you'll find uphill driving more effortless and passengers more comfortable. After all, maintaining control and power should always come first when driving.
