07 05.22 Use the front drive control switches and center differential lock switch to select the transfer and center differential modes. In the "4HI" and "4LO" mode, you can choose to lock or unlock the center differential. Use the center differential lock system if your wheels get stuck in a ditch, or when you are driving on a slippery or bumpy surface. When the center differential is locked, the vehicle stability control system is automatically turned off and the center differential lock and "VSC OFF" indicator lights come on because the function that controls engine performance interferes with the process of freeing your wheels. "2WD" mode (high speed, two−wheel drive) This mode is the normal driving mode. In this mode, the "4HI" and "4LO" indicator lights are turned off. Use this for normal driving on dry hard− surfaced roads. This position gives greater economy, quietest ride, least wear and better vehicle control. "4HI" mode (high speed, four −wheel drive, center differential unlocked) To select this mode, press the "2WD/4HI" switch only. The "4HI" indicator light comes on. 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. "4HI" mode (high speed, four −wheel drive, center differential locked) To select this mode, press the "2WD/4HI" switch, and then the center differential lock switch. The "4HI" and the center differential lock indicator lights come on. Use this for greater traction when you experience a loss of power, such as wheel slipping, in the center differential unlock mode. "4LO" mode (low speed, four −wheel drive, center differential unlocked) To select this mode, press the "4LO" switch only. The "4LO" indicator light comes on. Use this for maximum power and traction. Use this for climbing 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 "4LO" (low speed, four −wheel drive, center differential locked) mode. NOTICE As soon as the center differential lock switch is turned on, the "VSC OFF" indicator light comes on. After the wheels are out of the ditch or off the slippery or bumpy surface, turn the center differential lock switch off. Make sure that the center differential lock indicator light and "VSC OFF" indicator light turn off. 180 2007 SEQUOIA from Aug. '07 Prod. (OM34462U)
