Toyota 4Runner 2003 Operating Manual page 143

"L4" (low speed position, center differ-
ential unlocked): Four–wheel drive control
switch knob at "L4", center differential lock
switch left out
The "4LO" (low speed four–wheel drive)
indicator light comes on when the "L4"
mode is selected.
Use this for maximum power and traction.
Use this for climbing or descending steep
hills, off–road driving, and hard pulling in
sand or mud.
In this mode, the braking feeling that oc-
curs when the wheels are negotiating a
sharp corner is further reduced than in the
"L4" (low position, center differential
locked) mode.
"L4" (low speed position, center differ-
ential locked): Four–wheel drive control
switch knob at "L4", center differential lock
switch pushed in
The "4LO" (low speed four–wheel drive)
indicator light comes on when the "L4"
mode is selected.
'03 4Runner_U (L/O 0211)
Use this for maximum power and traction.
Use this for hard pulling in situations the
vehicle cannot negotiate even in the "L4"
(low speed position, center differential un-
locked) mode. Also, using this mode when
driving down steep off–road inclines will
help contribute to increased vehicle stabil-
ity.
The indicator light tells when the differen-
tial lock is engaged. Note that the differ-
ential is not still locked as long as the
indicator light remains off.
When the operation is not completed, the
indicator blinks. If the indicator light does
not go off when you push out the center
differential lock switch, drive
ahead while accelerating or decelerating,
or drive in reverse.
If the center differential lock system op-
eration is not completed within 5 seconds
while the cruise control system is set,
cancel the cruise control system. To can-
cel the cruise control system, see "Cruise
control" on page 162 in Section 1–6.
If the indicator blinks even if doing so,
contact your Toyota dealer as soon as
possible. There may be a trouble in the
center differential lock system.
See "(b) Shifting procedure" for further in-
structions.
Advice for driving on slippery roads in
"L4" (low speed position) mode
If the four–wheel drive control switch knob
is in the "L4" and the automatic transmis-
sion selector lever is in the "2" or "3"
when you drive in steep off–road areas,
the output of the brake can be controlled
effectively by the active traction control
system, which assists the driver to control
the driving power of 4 wheels.
Use the "L" position of the automatic
transmission selector 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
straight
of the brake can be controlled by the
active traction control system if the engine
speed is under 3000 rpm (normally engine
speed is under 3000 rpm when the wheels
get unstuck).
