Hill Descent Control
WARNING: This page is about a different car, the 2009 Jeep Patriot and 2009 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
Hill Descent Control (HDC) is included on vehicles equipped with the Off-Road Group (sales code AWL). It provides downhill assistance at a safe and controlled rate of speed without requiring the driver to touch the brakes or press a button. This feature operates in low and reverse gears. By means of electronics it replaces the gear reduction and engine braking that a traditional mechanical low-range transfer case provides. For ease of operation, HDC is activated and deactivated automatically according to changes in topography using grade sensing.
