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 straight
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 195 in Section 1- 7.
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.
