What gear should be used when driving an automatic transmission car uphill?

[Manuel]

When driving an automatic transmission car uphill, it is necessary to use a lower gear. There are several key points to pay attention to: 1. Shift the gear to L (Low) position. This locks the transmission between 1st and 2nd gears. Climbing hills requires greater torque to propel the vehicle upward and overcome slope resistance. 2. D1 position locks the gear in 1st, while D2 position locks between 1st and 2nd gears. 3. S (Sport) mode can also be used for hill climbing. Although S mode provides powerful performance for effortless uphill driving, prolonged use may cause engine overload and potential damage. 4. M (Manual) mode is another option. This manual shifting feature allows drivers to manually upshift or downshift using "M+" and "M-" controls, offering more precise operation according to actual driving conditions during climbing or overtaking. 5. Many modern vehicles are equipped with Hill Start Assist systems, which not only prevent rollback but also ensure more stable starts on inclines.
