(k) If you cannot shift the selector le-
ver out of “P” position
If you cannot shift the selector lever from
the “P” position even though the brake
pedal is depressed, use the shift lock
override lever. For instructions, see “If you
cannot shift automatic transmission selec-
tor lever” in Section 4.
“H” (2WD) MODE
“H” (4WD) MODE (center
differential unlock), “L4”
MODE (center differential
unlock) or “N” MODE
“H” (4WD) MODE (center
differential lock), “L4”
MODE (center differential
lock) or “N” MODE
Use the front drive control lever, “4WD”
button 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.

11 62002 MY 4RUNNER_U (OM 35787U)
“H” mode (high speed position, two
wheel drive): Front drive control lever at
“H”, “4WD” button 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” button push in, center differential
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):
Lever at “H”, “4WD” button pushed in cen-
ter differential lock switch pushed in
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.
The transmission automatically shifts up
from second gear in this mode. This sys-
tem is effective when starting your vehicle
in sand, mud, ice or snow. (However, 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 push in
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.
Fourwheel drive and center differential
lock indicator lights show which transfer
and center differential mode the vehicle is
in. Note that the differential is not still
locked as long as the indicator light re-
mains off.
When the shifting has not been completed
within 3 seconds after the shifting opera-
tion, the indicator flashes. If the indicator
light does not go off when you push out
the center differential lock button, drive
straight ahead while accelerating or decel-
erating, 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 center differential
lock 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.

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 to the 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.

If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.Fourwheel drive models only—
This switch can function only when the
fourwheel drive system is selected.
If your wheels get stuck in a ditch or
when you are driving on severe off
road and sand, turn off the vehicle skid
control system. This system that con-
trols engine performance interferes with
the process of freeing your wheels.

CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle:
Drive carefully when off the road.
Do not take unnecessary risks by
driving in dangerous places.
Do not grip the steering wheel
spokes when driving offroad. A
bad bump could jerk the wheel and
injure your hands. Keep both hands
and especially your thumbs on the
outside of the rim.
Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.
After driving through tall grass,
mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or
trapped on the underbody. Clear off
any such matter from the under-
body. If the vehicle is used with
these materials trapped or adhering
to the underbody, a breakdown or
fire could occur.
In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Therefore, the driver and all
passengers should fasten their seat
belts whenever the vehicle is mov-
ing.
When driving offroad or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover
causing death or serious injury. You
are also risking expensive damage
to your vehicle’s suspension and
chassis.
NOTICE
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the river bed for
firmness. Drive slowly and avoid
deep water.
 Take all necessary safety measures
to ensure that water damage to the
engine or other components does
not occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil’s lubricating qualities.
 Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.
