Which gear should be used for climbing hills in a semi-automatic transmission car?

For climbing hills in a semi-automatic transmission car, the S gear (Sport mode) is suitable. Here's an introduction to the gears in a semi-automatic transmission car: 1. P stands for Parking gear, used when the vehicle is parked for an extended period and should be used in conjunction with the handbrake; 2. R stands for Reverse gear, used when reversing the vehicle; 3. D is the Drive gear, also known as the forward driving gear; 4. S is the Sport gear; 5. D plus or minus refers to the manual mode, allowing manual gear shifting - push up to shift to a higher gear and pull down to shift to a lower gear. A semi-automatic transmission combines manual and automatic transmissions, aiming to enhance the fuel efficiency and control of the automatic transmission by giving the driver control over gear shifting, which is typically decided by the computer.
When driving a manual-automatic transmission car uphill, I often switch to manual mode for better control, as the automatic transmission tends to shift frequently on steep slopes, making the car feel unstable or consuming more fuel. I manually shift to 2nd or 3rd gear depending on the steepness, which increases the engine RPM and provides more power for a smoother climb. For example, on long steep slopes, using a lower gear can prevent slipping or stalling, and the same method is used downhill to reduce brake wear. Remember not to shift into 1st gear unless the slope is extremely steep, as it can cause excessive engine noise or overheating. Before tackling any uphill climb, I always check the car's condition to ensure a more confident and stable drive.
