Range Rover: Gradient release control (GRC) - Hill descent control (HDC) - Range Rover Owner's ManualRange Rover: Gradient release control (GRC)

With HDC activated, if the vehicle is stopped on a slope using the foot brake, GRC will become active (except in Terrain response Sand program). During a hill ascent when the foot brake is released GRC will automatically delay and graduate the brake release, to allow the vehicle to move smoothly away.
