How to operate an automatic car on a long slope?

The cars on the market now are nothing more than automatic transmission and manual transmission. If compared, there are still some differences. So how should an automatic car run down a long slope?

In fact, when an automatic car goes down a long slope, how to operate it is also very particular. Usually, the steepness and length of the slope are different, so the operation will be different, as follows:

If it is a slow ramp, the owner can hang the gear of the vehicle in the D gear, and then drive the vehicle downhill while stepping on the brakes, paying attention to controlling the speed.

If it is a steep slope, then you can't use the D gear of the vehicle and step on the brakes to go downhill, because doing so will overheat the brake pedal of the vehicle and affect the braking performance of the vehicle. The owner needs to shift the gear of the vehicle to L gear (low gear) or M gear (low gear in manual gear mode), and then drive the vehicle downhill to minimize the number of brakes.

The main attention of the car is not to slide in neutral, which will lead to the loss of containment of the vehicle engine and prone to safety hazards.
