The optional, class-exclusiveclass-exclusive* Terrain Management System allows you to easily shift on the fly into one of four settings to match the terrain you're driving on: Normal – biases torque to the front wheels and sends it to the rear only as needed; Mud/Ruts – switches the throttle to a more aggressive mode, limits upshifting and desensitizes stability control, allowing the tires to spin as needed; Sand – the throttle throws maximum torque to the wheels, placing the transmission in lower gears for as long as possible, which allows the wheels to spin aggressively; Grass/Gravel/Snow – places the throttle in a setting to minimize wheelslip.
