What is the correct method to control speed during a long downhill descent?
1 Answers
When descending a long slope, the correct method to control speed is to drive in a low gear. If speed is not properly controlled and braking is excessively relied upon, it can easily cause the brake pads to overheat, leading to vehicle failure and increasing the risk of traffic accidents. Here is more information about descending long slopes: 1. For manual transmission vehicles, it is relatively simple. Just place the transmission in a low gear, use engine braking, and combine it with the brakes to keep the speed within a reasonable range. 2. For automatic transmission vehicles or vehicles with manual-automatic transmission, the following points should be noted when descending a long slope: First, do not shift the transmission into N (neutral) gear when descending, as this can damage the transmission and make speed control difficult, leading to overheated brake pads and loss of speed control. For long descents with moderate slopes but extended distances, first switch the vehicle to manual mode, then adjust to third gear in manual mode, using engine braking combined with the brakes. For steeper long descents, switch the vehicle to manual mode and adjust to first gear in manual mode, using engine braking combined with the brakes. Some vehicles are equipped with an L (low) gear, which can be used for descending by placing the transmission in low gear.
