The A.D.D. can be engaged or disen-
gaged by the shifting operations de-
scribed in "(c) Shifting procedure".
You should drive in four- wheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.

(c) Shifting procedure
SHIFTING BETWEEN "H2" AND "H4"
(UNLOCKED)
To shift from "H2" to "H4" (unlocked),
reduce the vehicle speed to less than 100
km/h (62 mph) and turn the multi- mode
control switch knob fully clockwise.
If the four- wheel drive indicator light con-
tinues to blink when you operate the mul-
ti- mode control switch knob from the "H2"
to the "H4" position, this reminds you that
the transfer mode is not securely in "H4"
mode. Drive straight ahead while acceler-
ating or decelerating.
If the four- wheel drive indicator light con-
tinues to blink and the buzzer sounds
when you operate the multi- mode control
switch knob from the "H2" to the "H4"
position, this reminds you that the transfer
mode is not in "H4" mode. Stop the ve-
hicle or reduce the vehicle speed to less
than 100 km/h (62 mph). Operate the
switch knob again.
To shift from "H4" (unlocked) to "H2",
turn the multi- mode control switch knob
fully counterclockwise.
This can be done at any speed.
If the four- wheel drive indicator light con-
tinues to blink when you operate the mul-
ti- mode control switch knob from the "H4"
to the "H2" position, this reminds you that
the transfer mode is not securely in "H2"
mode. Drive straight ahead while acceler-
ating or decelerating, or drive forward or
backward in a short distance.
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.
CAUTION
Never operate the multi- mode control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.
