Gradient Release Control
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, 2016 Land Rover Range Rover, 2015 Land Rover Range Rover, and 2014 Land Rover Range Rover. 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 program and rock crawl).
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.
