Gradient Release Control (GRC) improves the vehicle’s ability to smoothly pull away from a standstill when on an incline or decline. GRC achieves this by automatically controlling brake operation once the brake pedal is released. No driver intervention is required.
GRC operates when forward or reverse gears are selected.
GRC also operates if the brakes are applied while Hill Descent Control (HDC) is active. See HILL DESCENT CONTROL (HDC).
GRC does not operate if the terrain response sand driving program is selected. See SAND.
