Gradient Release Control
WARNING: This page is about a different car, the 2018 Land Rover Discovery and 2017 Land Rover Discovery. However, it is still accessible from the selected car via links, so may be relevant.
Gradient release control is an automatic feature which is always available when Hill Descent Control (HDC) is selected.
If the vehicle is brought to a standstill on a slope using the foot brake, gradient release control will become active (except in the Terrain Response®, sand and rock crawl program).
When descending a hill, a brake hold and gradual release is employed to provide a smooth transition into HDC. Gradient release control operates in forward and reverse gears and requires no driver intervention.
