The Jeep® Grand Cherokee features three available systems designed to give you added control in difficult off-roading situations. Hill Descent Control detects steep declines and automatically applies brake pressure for a consistent descent speed. Hill Start Assist lets you tackle sharp inclines by holding the brakes, preventing roll-back. Selec-Speed® Control allows the driver to travel at slow speeds on level ground, uphill or downhill without actively controlling either the throttle or the brake.
