'04 TUNDRA_U (L/O 0309) Four −wheel drive system- (a) Front drive control (lever type) "N" (neutral position): Lever at "N" No power is delivered to the wheels. The vehicle must be stopped. "L4" (low speed position, four−wheel drive): Lever at "L4" Use this for maximum power and traction. Use "L4" for climbing or descending steep hills, off −road driving, and hard pulling in sand, mud or deep snow. The "4WD" (four −wheel drive) indicator light comes on when the "H4", "N" or "L4" mode is selected. Use the front drive control lever to select the following transfer modes. "H2" (high speed position, two−wheel drive): Lever at "H2" Use this for normal driving on dry, hard− surfaced roads. This position gives greater economy, the quietest ride and least wear. "H4" (high speed position, four−wheel drive): Lever at "H4" Use this for normal driving on wet, icy or snow−covered roads. This position provides greater traction than two−wheel drive. See "(c) Shifting procedure (lever type)" for further instructions. Advice for driving on slippery roads in "L4" (low speed position, four wheel drive) mode If you shift the front drive control lever to "L4" and the automatic transmission lever to "2" when you drive in steep off −road areas, the output of the brake can be controlled effectively by the traction control system, which assists the driver to control the driving power of 4 wheels. Use the "L" position of the automatic transmission 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 traction control system if the engine speed is under 3000 rpm (normally engine speed is under 3000 rpm when the wheels get unstuck). D The front drive control lever in the "L4" position and the automatic transmission lever in the "L" position or the automatic transmission lever in the "D" or "2" with the transmission downshifting to the first gear D The front drive control lever in the "L4" position and the automatic transmission lever in the "R" position (As for the automatic transmission lever positions, see "Automatic transmission" in this Section.) 171 2004 TUNDRA from Sep.
