06 06.07 "H2" (high speed position, two−wheel drive, center differential unlocked): Multi−mode control switch knob at "H2", center differential lock switch left out Use this for normal driving on dry hard− surfaced roads. This position gives greater economy, quietest ride, least wear and better vehicle control. "H4" (high speed position, four−wheel drive, center differential unlocked): Multi−mode control switch knob at "H4", center differential lock switch left out The four−wheel drive indicator light comes on when the "H4" mode is selected. Use this for greater traction than two− wheel drive. (When you experience a loss of power, such as wheel slipping.) This position provides greater traction than two−wheel drive. "H4" (high speed position, four−wheel drive, center differential locked): Multi− mode control switch knob at "H4", center differential lock switch pushed in The four−wheel drive indicator light comes on when the "H4" mode is selected. Use this for greater traction when you experience a loss of power, such as wheel slipping, in the center differential unlock mode. "L4" (low speed position, four−wheel drive, center differential unlocked): Multi−mode control switch knob at "L4", center differential lock switch left out The four−wheel drive and "4LO" (low speed four−wheel drive) indicator lights come on when the "L4" mode is selected. Use this for maximum power and traction. Use this for climbing or descending steep hills, off−road driving, and hard pulling in sand or mud. In this mode, the braking feeling that occurs when the wheels are negotiating a sharp corner is further reduced than in the "L4" (low speed position, four−wheel drive, center differential locked) mode. "L4" (low speed position, four−wheel drive, center differential locked): Multi− mode control switch knob at "L4", center differential lock switch pushed in The four−wheel drive and "4LO" (low speed four−wheel drive) indicator lights come on when the "L4" mode is selected. Use this for maximum power and traction. Use this for hard pulling in situations the vehicle cannot negotiate even in the "L4" (low speed position, four−wheel drive, center differential unlocked) mode. Also, using this mode when driving down steep off− road inclines will help contribute to increased vehicle stability. The indicator light tells when the differential lock is engaged. Note that the differential is not still locked as long as the indicator light remains off. When the operation is not completed, the indicator blinks. If the indicator light does not go off when you push out the center differential lock switch, drive straight ahead while accelerating or decelerating, or drive in reverse. If the center differential lock system operation is not completed within 5 seconds while the cruise control system is set, cancel the cruise control system. To cancel the cruise control system, see "Cruise control" on page 196 in Section 1−7. If the indicator blinks even if doing so, contact your Toyota dealer as soon as possible. There may be a trouble in the center differential lock system. See "(c) Shifting procedure" for further instructions. 168 2007 4Runner from Aug. '06 Prod. (OM35866U)
