STARTING AND DRIVING LIMITED-SLIP DIFFERENTIAL Your Lexus is equipped with a limited-slip center differential (transfer). If one wheel - either front or rear - begins to spin, the transfer (limited-slip center differential) is designed to aid traction by automatically transmitting driving force to the wheels on the other drive axle. It transmits driving force to the front wheels if a rear wheel spins, and to the rear wheels if a front wheel spins. CAUTION Do not start or run the engine while your vehicle is supported by a jack. The vehicle could be driven off the jack and could pose a danger or result in serious injury. NOTICE Use only a spare tire of the same size, construction and load capacity as the original tires on your Lexus because damage to the limited-slip differential could possibly occur with another tire type. 445
