Which gear should be used when driving down a steep slope?

[DeAngelo]

When driving down a steep slope, use the 3rd gear. The precautions include: 1. Reduce the speed before descending to enter the slope at a slow speed; 2. Shift into an appropriate gear before descending, preferably the 2nd or 3rd gear, and avoid shifting gears after entering the downhill section; 3. Do not coast in neutral on a downhill slope; always engage an appropriate gear to utilize the engine's braking effect to control the vehicle's speed; 4. Test the brake performance before descending to ensure it is in good condition; 5. Avoid sudden steering wheel movements on downhill slopes, as the high inertia and speed combined with improper steering can easily cause the vehicle to overturn; 6. Maintain a distance of at least 50 meters from the vehicle ahead.
