CAUTION
Never operate the front drive control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.
To shift from "4H" to "2WD", reduce the
vehicle speed to less than 100 km/h (62
mph) and turn the front drive control
switch knob fully counterclockwise.
When you operate the front drive control
switch knob from "4H" to "2WD" with the
vehicle speed at 100 km/h (62 mph) or
higher, the "4HI" indicator light continues
to blink and buzzer sounds. When the
switch knob is returned from "2WD" to
"4H", the indicator light turns off and the
buzzer stops sounding.
If the "4HI" (high speed four−wheel drive)
indicator light continues to blink when you
operate the front drive control switch knob
from the "4H" to the "2WD" position, this
reminds you that the transfer mode is not
securely in "2WD" mode. Drive straight
ahead while accelerating or decelerating,
or drive forward or backward for a short
distance.

If there is any malfunction within the
brake system, "4HI" or "4LO" indicator
light blinks and the transfer mode may not
be able to be shifted from "4H" to "2WD".
If the indicator light continues to blink
even if doing so, contact your Toyota
dealer as soon as possible. There may be
a trouble in the four−wheel drive system.
