Gradient Release Control
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.
