07 11.20 Four −wheel drive system (a) Front drive control To turn off: Push "TOW/HAUL" switch once again and the "TOW/HAUL" mode indicator light goes off. "TOW/HAUL" mode is canceled by pressing "TOW/HAUL" switch again or by turning the engine switch to "OFF". Even when "TOW/HAUL" mode is used during normal driving, no damage is caused to the engine or the transmission. However, fuel economy is reduced and the transmission and/or engine driving characteristics may feel unusual. Toyota recommends using "TOW/HAUL" mode only when a heavy trailer or a large heavy load is towed. Use the front drive control switch knob to select the following transfer modes. "2WD" (high speed position, two−wheel drive): Front drive control switch knob at "2WD" Use this for normal driving on dry hard− surfaced roads. This position gives greater economy, quietest ride, least wear and better vehicle control. "4H" (high speed position, four −wheel drive): Front drive control switch knob at "4H" XS17003b The "4HI" (high speed four −wheel drive) indicator light comes on when the "4H" mode is selected. Use this for greater traction than two− wheel drive. (When you experience a loss of power, such as wheel spinning.) This position provides greater traction than two−wheel drive. In this mode, the vehicle stability control system is off. (See "Vehicle stability control system" on page 250 in this Section.) "4L" (low speed position, four−wheel drive): Front drive control switch knob at "4L" 240 2008 TUNDRA from Apr. '08 Prod. (OM34477U)
