tance, then stop the vehicle completely,
shift the automatic transmission selector
lever securely into “N” and operate the
switch knob again.
If the indicator continues to blink even if
doing so, contact your Toyota dealer as
soon as possible. There may be a trouble
in the fourwheel drive system.

Multimode control switch knob
Center differential lock switch
Use the multimode control switch
knob and center differential lock switch
to select the transfer and center differ-
ential modes.
The “H4” and “L4” positions of the multi
mode control switch knob provide either
lock or unlock mode of the center differen-
tial depending on the center differential
lock switch position. 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 stability control system
is automatically turned off and the center
differential 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 vehicle stabil-
ity control system off indicator light
turn off.

“H2” (high speed position, twowheel
drive, center differential unlocked): Mul-
timode control switch knob at “H2”, cen-
ter differential lock switch left out
Use this for normal driving on dry hard
surfaced roads. This position gives greater
economy, quietest ride, least wear and
better vehicle control.
“H4” (high speed position, fourwheel
drive, center differential unlocked): Mul-
timode control switch knob at “H4”, cen-
ter differential lock switch left out
The fourwheel drive indicator light comes
on when the “H4” mode is selected.
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.
“H4” (high speed position, fourwheel
drive, center differential locked): Multi
mode control switch knob at “H4”, center
differential lock switch pushed in
The fourwheel drive indicator light comes
on when the “H4” mode is selected.
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode. “L4” (low speed position, fourwheel
drive, center differential unlocked):
Mul-
timode control switch knob at “L4”, cen-
ter differential lock switch left out
The fourwheel drive and “4LO” (low
speed fourwheel drive) indicator lights
come on when the “L4” mode is selected.
Use this for maximum power and traction.
Use this for climbing or descending 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 speed position, fourwheel drive,
center differential locked) mode.
“L4” (low speed position, fourwheel
drive, center differential locked): Multi
mode control switch knob at “L4”, center
differential lock switch pushed in
The fourwheel drive and “4LO” (low
speed fourwheel drive) indicator lights
come on when the “L4” mode is selected. 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 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 164 in Section 16.
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 “(c) Shifting procedure” for further in-
structions.

reduce the vehicle speed to less than 100
km/h (62 mph) and turn the multimode
control switch knob fully clockwise.
If the fourwheel drive indicator light con-
tinues to blink when you operate the mul-
timode 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 fourwheel drive indicator light con-
tinues to blink and the buzzer sounds
when you operate the multimode 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 multimode control switch knob
fully counterclockwise.
This can be done at any speed.

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 fourwheel drive system.
CAUTION
Never operate the multimode control

If the light comes on while driving, the
active traction control system does not
work. However, as normal braking oper-
ates when being applied, there is no prob-
lem to continue your driving.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing. The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the output of the brakes or engine to
help prevent the vehicle from skidding
when cornering on a slippery road sur-
face or operating steering wheel abrupt-
ly.
The vehicle stability control activates
when the vehicle speed is more than 15
km/h (9 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the sys-
tem is in the selfcheck mode, but does
not indicate a malfunction.
CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
blinks and an alarm sounds, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” on
page 333 in Section 72.)

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—
Pushing the center differential lock
switch automatically turns the vehicle
stability control system off. At this
time, the “VSC OFF” indicator comes
on with the center differential lock indi-
cator light.
“VSC OFF” indicator light comes on for a
few seconds when the ignition key is
turned to “ON”. It will come on again
when you push the center differential lock
switch to turn off the system. In the following cases, contact your Toyota
dealer:
The indicator light does not come on
when the ignition key is turned to
“ON”.
The indicator light remains on after the
ignition key is turned to “ON”.
The indicator light comes on when the
system is on while driving.
