NOTICE
Always use the brake pedal or the
parking brake to hold the vehicle on
an upgrade. Do not attempt to hold
the vehicle using the accelerator ped-
al, as this can cause the transmission
to overheat.
“H” (2WD) MODE
“H” (4WD) MODE (center
differential unlock) or “L4”
MODE (center differential
unlock)
“H” (4WD) MODE (center
differential lock) or “L4”
MODE (center differential
lock)
Use the front drive control lever, “4WD”
switch and center differential lock
switch to select the transfer and center
differential modes.
The “H” and “L4” position of the front
drive control lever provide either lock or
unlock the mode of the center differential.
Use the center differential lock system if
your wheels get stuck in a ditch, or when
you are driving on a slippery or bumpy
surface. When the center differential is
locked, the vehicle skid control system is
automatically turned off and the center dif-
ferential lock and “VSC OFF” indicator
lights come on because the function that
controls engine performance interferes
with the process of freeing your wheels.
NOTICE
As soon as the center differential lock
switch is turned on, the “VSC OFF”
indicator light comes on. After the
wheels are out of the ditch or off the
slippery or bumpy surface, turn the
center differential lock switch off.
Make sure that the center differential
lock indicator light and “VSC OFF”
indicator light turn off.

“H” mode (high speed position, two
wheel drive): Front drive control lever at
“H”, “4WD” switch left out
Use this for normal driving on dry hard
surfaced roads. This position gives greater
economy, quietest ride and least wear and
better vehicle control.
“H” mode (high speed position, four
wheel drive, center differential un-
locked): Front drive control lever at “H”,
“4WD” switch pushed once, center differ-
ential lock switch left out
Use this for normal driving on all types of
roads, from dry hardsurfaced roads to
wet, icy or snowcovered roads. This
position provides greater traction than
twowheel drive.
“H” mode (high speed position, four
wheel drive, center differential locked):
Front drive control lever at “H”, “4WD”
button pushed once center differential lock
switch pushed once
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode.
“N” mode (neutral position): Front drive
control lever at “N”
No power is delivered to the wheels. The
vehicle must be stopped. “L4” mode (low speed position, four
wheel drive, center differential un-
locked):
Front drive control lever at “L4”,
center differential lock switch left out
Use this for maximum power and traction.
Use this for climbing steep hills, offroad
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, fourwheel drive, center
differential locked) mode.
If you place the transmission shift lever at
“2” in this mode, the transmission auto-
matically shifts up from second gear. This
system is effective when starting your ve-
hicle in sand, mud, ice or snow. (Howev-
er, the transmission system may shift up
from first gear when the vehicle starts too
quickly.) “L4” mode (low speed position, four
wheel drive, center differential locked):
Front drive control lever at “L4”, center
differential lock switch pushed once
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, fourwheel drive, cen-
ter differential unlocked) mode. Also, using
this mode when driving down steep off
road inclines will help contribute to in-
creased vehicle stability.
The indicator shows which transfer and
center differential mode the vehicle is in.
When the shifting operation has not been
completed after moving the lever, the
indicator flashes. 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 indicator flashes
even if doing so, contact your Toyota
dealer as soon as possible. There may be
a trouble in the four wheel drive system.
See “(c) Shifting procedure” for further in-
structions.

Advice for driving on slippery roads in
“L4” (low speed position) mode
If you shift the front drive control lever to
“L4” and the automatic transmission lever
to “2” when you drive in steep offroad
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 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 active trac-
tion control system if the engine speed is
under 3000 rpm (normally engine speed is
under 3000 rpm when the wheels get un-
stuck).
The front drive control lever in the “L4”
position and the automatic transmission
lever in the “L” position or the automat-
ic transmission lever in the “D” or “2”
with the transmission downshifting to
the first gear
The front drive control lever in the “L4”
position and the automatic transmission
lever in the “R” position(As for the automatic transmission lever
positions, see “Automatic transmission” in
this section.)
The A.D.D. can be engaged or disen-
gaged by the shifting operations des-
cribed in “(c) Shifting procedure”.
You should drive in fourwheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.

disconnecting differential)

NOTICE
Do not drive on a dry paved surface
in “L4” (LOCKED) mode. This may
damage the locking mechanism and
the drive system.
The traction control system automatical-
ly helps prevent the spinning of rear
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against rear wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.
