STARTING AND DRIVING (g) If you cannot shift the selector lever If you cannot shift the selector lever even though the brake pedal is depressed, use the shift lock override button. For instructions, see "If you cannot shift automatic transmission selector lever" on page 524. FOUR-WHEEL DRIVE SYSTEM (a) Four-wheel drive control (h) Driving in second start mode Use the four-wheel drive control lever and center differential lock switch to select the following transfer and center differential modes. In the second start mode, the transmission system shifts up from second gear. Use this mode when starting your vehicle in sand, mud, ice or snow. To set the second start mode, push the "2nd STRT" switch. In the second start mode, the "2nd STRT" indicator light comes on. To cancel the second start mode, push the "2nd STRT" switch once again. The "H" and "L" position of the four-wheel drive control lever provides either lock or unlock mode of the center differential depending on the center differential lock switch position. 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. 411
