Four-wheel-drive 2007 Mitsubishi Outlanders feature a rotary dial between the front seats which controls three settings. In 2WD mode, all of the engine's power is directed to the front wheels; in 4WD Auto power is delivered to the rear wheels when slippage occurs; and 4WD Lock is best suited for optimal traction on slippery or rough surfaces by pushing added power to the rear wheels immediately. The 4WD settings can be used on any road surface, and selecting a mode can be done at any speed.
