Gradient Release Control

Gradient release control is an automatic system which is always available when Hill Descent Control (HDC) or All Terrain Progress Control (ATPC) 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).

When descending a hill, a brake hold and gradual release is employed to provide a smooth transition into HDC or ATPC. Gradient release control operates in forward and reverse gears and requires no driver intervention.
