Which statement about coasting downhill with the engine off is wrong?

A

For vehicles that use a vacuum-assisted brake system, stalling during downhill driving will cause the brake system to fail.

B

For vehicles equipped with power steering systems, stalling while going downhill will make the steering wheel heavier and difficult to control.

C

When the vehicle shut off on a downhill slope, the engine cannot be used for braking.

D

Sliding downhill is using the potential energy of the slope to propel the car forward. The engine is not working, which can save fuel and should be strongly promoted.
