There is only one constant in this world, and that is change. As driving conditions change, from one road to the next, even from one moment to the next, the available advanced 4WD is ready. It constantly calculates the precise traction needed and reacts with millisecond response time. Set the dash- mounted switch to AUTO and the system continually adjusts the amount of power distributed between front and rear wheels to help enhance traction control and acceleration. The system also lets you take control with settings for 2WD, 4WD High, even 4-LO.
