'03 4Runner_U (L/O 0211) "L4" (low speed position, center differential unlocked): Four-wheel drive control switch knob at "L4", center differential lock switch left out The "4LO" (low speed four-wheel drive) indicator light comes 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 position, center differential locked) mode. "L4" (low speed position, center differential locked): Four-wheel drive control switch knob at "L4", center differential lock switch pushed in The "4LO" (low speed four-wheel drive) indicator light comes 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, 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 162 in Section 1-6. 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 "(b) Shifting procedure" for further instructions. Advice for driving on slippery roads in "L4" (low speed position) mode If the four-wheel drive control switch knob is in the "L4" and the automatic transmission selector lever is in the "2" or "3" when you drive in steep off-road areas, the output of the brake can be controlled effectively by the active traction control system, which assists the driver to control the driving power of 4 wheels. Use the "L" position of the automatic transmission selector lever for maximum power and traction when your wheels get stuck or when you drive down a steep incline. In the following cases, the output of the brake can be controlled by the active traction control system if the engine speed is under 3000 rpm (normally engine speed is under 3000 rpm when the wheels get unstuck).
