Can automatic transmission cars use N gear when going downhill?
1 Answers
It is best not to use N gear for automatic transmission cars when going downhill. 1. Why N gear should not be used: N gear is the neutral gear, which is generally used when parking. When in neutral gear, if going downhill, the engine is essentially idling, and the fuel does not burn completely. Incomplete fuel combustion can easily lead to carbon buildup, ultimately damaging the engine. Many people think that no fuel is consumed in neutral gear, but this is completely incorrect. 2. How to shift gears when going downhill: When driving downhill, if encountering a long descent, you can use the L, M, or D gears on the vehicle, but never use N gear to coast. If the vehicle suddenly stalls while coasting in neutral, it can cause the steering wheel to lock.
