GRADIENT RELEASE CONTROL (GRC)

The Gradient Release Control (GRC) system operates when the vehicle is pulling away from a standstill on an incline or a decline. When the vehicle's brakes are released, the GRC system automatically delays and graduates the brake release to allow the vehicle to pull away smoothly.

The GRC system automatically operates in forward and reverse gears. No driver intervention is required.

If the brakes are applied with the Hill Descent Control (HDC) system enabled, the GRC system activates to allow a smooth transition into HDC operation.

The GRC system does not operate if the terrain response sand driving program is enabled. See SAND.
