Four−Wheel Drive System - Toyota TUNDRA 2004 Owner's Manual

Four−wheel drive system—
(a) Front drive control
(lever type)
Use the front drive control lever to se-
lect 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 pro-
vides greater traction than two−wheel
drive.
'04 TUNDRA_U (L/O 0309)
"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.
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 con-
trol 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 un-
der 3000 rpm (normally engine speed is
under 3000 rpm when the wheels get un-
stuck).
