Toyota 2008 Tundra - Four−Wheel Drive System

240
2008 TUNDRA from Apr. ’08 Prod. (OM34477U)
To turn off: Push “TOW/HAUL” switch
once again and the “TOW/HAUL” mode
indicator light goes off.
“TOW/HAUL” mode is canceled by press-
ing “TOW/HAUL” switch again or by turn-
ing 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 charac-
teristics 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”
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”
