If the automatic unlocking operation linked
to shift lever position is set, all doors are
automatically unlocked when the selector
lever is moved to ªPº position after the
ignition switch is turned to ªONº position.
For details, see ªÐAutomatic door locking
and unlocking functionsº on page 27 in
Section 1±2.
(i) Good driving practice

If the transmission repeatedly shifts up
and down between fourth gear and
overdrive when climbing a gentle slope,
the overdrive should be turned off. Be
sure to turn the switch on immediately
afterward.

When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
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.

Use the front drive control switches
and center differential lock switch to
select the transfer and center differen-
tial modes.
In the ª4HIº and ª4LOº mode, you can
choose to lock or unlock the center differ-
ential.
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 ªVSC OFFº 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 ªVSC OFFº
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 ªVSC OFFº
indicator light turn off.
ª2WDº mode (high speed, two±wheel
drive)
This mode is the normal driving mode. In
this mode, the ª4HIº and ª4LOº indicator
lights are turned off.
Use this for normal driving on dry hard±
surfaced roads. This position gives greater
economy, quietest ride, least wear and
better vehicle control.
ª4HIº mode (high speed, four±wheel
drive, center differential unlocked)
To select this mode, press the ª2WD/4HIº
switch only. The ª4HIº indicator light
comes on.
Use this for normal driving on all types of
roads, from dry hard±surfaced roads to
wet, icy or snow±covered roads. This
position provides greater traction than
two±wheel drive.ª4HIº mode (high speed, four±wheel
drive, center differential locked)
To select this mode, press the ª2DW/4HIº
switch, and then the center differential
lock switch. The ª4HIº and the center dif-
ferential lock indicator lights come on.
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode.
ª4LOº mode (low speed, four±wheel
drive, center differential unlocked)
To select this mode, press the ª4LOº
switch only. The ª4LOº indicator light
comes on.
Use this for maximum power and traction.
Use this for climbing steep hills, off±road
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
ª4LOº (low speed, four±wheel drive, center
differential locked) mode.

ª4LOº mode (low speed, four±wheel
drive, center differential locked)
To select this mode, press the ª4LOº
switch, and then press the center differen-
tial lock switch. The ª4LOº and the center
differential lock indicator lights come on.
Use this for maximum power and traction.
Use this for hard pulling in situations the
vehicle cannot negotiate even in ª4LOº
(low speed, four±wheel drive, center differ-
ential unlocked) mode. Also, using this
mode when driving down steep off±road
inclines will help contribute to increased
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 ªCruise
controlº on page 205 in Section 1±7.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 ª(c) Shifting procedureº for further in-
structions.
Advice for driving on slippery roads in
ª4LOº (low speed, four±wheel drive)
mode
If you press the ª4LOº switch and shift
the automatic transmission lever to ª2º
when you drive in steep off±road 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 ªLº position of the automatic
transmission for maximum power and trac-
tion when your wheels get stuck or when
you drive down a steep incline. The output
of the brake can be controlled by the
active traction control system if the engine
speed is under 3000 rpm (normally engine
speed is under 3000 rpm when the wheels
get unstuck), in the following cases:

The front drive control in ª4LOº mode
and the automatic transmission in ªLº
or the automatic transmission in ªDº,
ª3º or ª2º with the transmission down-
shifting to the first gear

The front drive control in ª4LOº mode
and the automatic transmission in ªRº
(As for the automatic transmission shift
positions, see ªAutomatic transmissionº on
page 173 in this Section.)

The A.D.D. can be engaged or disen-
gaged by the shifting operations des-
cribed in ª(c) Shifting procedureº.
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.SHIFTING BETWEEN ª2WDº MODE AND
ª4HIº MODE
To shift from ª2WDº mode to ª4HIº
mode, reduce your speed to less than
100 km/h (62 mph) and press the
ª2WD/4HIº switch.
If the ª4HIº indicator light flashes when
you press the ª2WD/4HIº switch, drive
straight ahead while accelerating or decel-
erating.
If the ª4HIº indicator light flashes and the
buzzer sounds when you press the
ª2WD/4HIº switch, reduce the vehicle
speed to less than 100 km/h (62 mph)
and press the switch again.
CAUTION
Never press the ª2WD/4HIº switch if
wheels are slipping. Stop the slipping
or spinning before shifting.
To shift from ª4HIº mode to ª2WDº
mode, press the ª2WD/4HIº switch again
to turn it off.
This can be done at any vehicle speed.
If the ª4HIº indicator light flashes when
you press the ª2WD/4HIº switch, drive
straight ahead while accelerating or decel-
erating, or drive in reverse.
SHIFTING BETWEEN ª4HIº (UNLOCKED)
AND ª4HIº (LOCKED)
To shift from ª4HIº (UNLOCKED) to
ª4HIº (LOCKED), press the center differ-
ential lock switch.
If the center differential lock indicator light
flashes when you press the center differ-
ential lock switch, drive straight ahead
while accelerating or decelerating.
CAUTION
Never press the center differential
lock switch if wheels are slipping.
Stop the slipping or spinning before
shifting.
