(b) Normal driving
1. Start the engine as instructed in “How to start the engine” on page 298 in
Section 3. The transmission must be in
“P” or “N”.
When the four −wheel drive control switch
knob is in “L4” (low −speed position, center
differential locked), the driving pattern se-
lector setting has no effect on gear shift
timing. (See “Four −wheel drive system
(full −time four −wheel drive models)” on
page 158 in this Section for information of
the four −wheel drive control.)
2. With your foot holding down the brake pedal, shift the selector lever to “D”.
When the lever is in the “D” position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc. Always use the “D” position for better fuel
economy and quieter driving. If the engine
coolant temperature is low or when the
four
−wheel drive control switch knob is in
“L4” (low −speed position, center differential
locked), the transmission will not shift into
the overdrive gear even in the “D” posi-
tion. (See “Four −wheel drive system (full −
time four −wheel drive models)” on page
158 in this Section for information of the
four −wheel drive control.)
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
If the automatic locking operation linked
with the shift position is set, all the side
doors and back door are automatically
locked when the shift lever is moved out
of the “P” position with the engine running
(including ignition switch in the “ON” posi-
tion) and all the side doors and back door
are closed. For details, see “—Automatic
door locking and unlocking functions” on
page 18 in Section 1 −2. (c) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Shift into the “4” position. The trans-
mission will downshift to fourth gear
and engine braking will be enabled.
Shift into the “3” position. The trans-
mission will downshift to third gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.

(b) Normal driving
1. Start the engine as instructed in “How to start the engine” on page 298 in
Section 3. The transmission must be in
“P” or “N”.
When the multi −mode control switch knob
is in “L4” (low −speed position, four −wheel
drive, center differential locked), the driv-
ing pattern selector setting has no effect
on gear shift timing. (See “Four −wheel
drive system (multi −mode four −wheel drive
models)” on page 161 in this Section for
information of the multi −mode control.)
2. With your foot holding down the brake pedal, shift the selector lever to “D”.
When the lever is in the “D” position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc. Always use the “D” position for better fuel
economy and quieter driving. If the engine
coolant temperature is low or when the
multi
−mode control switch knob is in “L4”
(low −speed position, four −wheel drive,
center differential locked), the transmission
will not shift into the overdrive gear even
in the “D” position. (See “Four −wheel drive
system (multi −mode four −wheel drive mod-
els)” on page 161 in this Section for in-
formation of the multi −mode control.)
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
If the automatic locking operation linked
with the shift position is set, all the side
doors and back door are automatically
locked when the shift lever is moved out
of the “P” position with the engine running
(including ignition switch in the “ON” posi-
tion) and all the side doors and back door
are closed. For details, see “—Automatic
door locking and unlocking functions” on
page 18 in Section 1 −2. (c) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Shift into the “3” position. The trans-
mission will downshift to third gear.
Shift into the “2” position. The trans-
mission will downshift to second gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.

Fourwheel drive control switch knob
Center differential lock switch
Use the fourwheel drive control switch
knob and center differential lock switch
to select the transfer and center differ-
ential modes.
The “H4” and “L4” positions of the four −
wheel drive control switch knob provide
either lock or unlock mode of the center
differential depending on the center differ-
ential 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.
“H4” (high speed position, center differ-
ential unlocked): Four−wheel drive control
switch knob at “H4”, center differential
lock switch left out
Use this for normal driving on all types of
roads, from dry hard −surfaced roads to
wet, icy or snow −covered roads. This
position gives greater economy, quietest
ride, least wear and better vehicle control.
“H4” (high speed position, center differ-
ential locked): Four−wheel drive control
switch knob at “H4”, center 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.

“L4” (low speed position, center differ-
ential unlocked): Four−wheel drive control
switch knob at “L4”, center differential lock
switch left out
The “4LO” (low speed four −wheel drive)
indicator light comes on when the “L4”
mode is selected.
Use this for maximum power and traction.
Use this for climbing or descending 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
“L4” (low position, center differential
locked) mode.
“L4” (low speed position, center differ-
ential locked): Four−wheel drive control
switch knob at “L4”, center differential lock
switch pushed in
The “4LO” (low speed four −wheel drive)
indicator light comes 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, center differential un-
locked) mode. Also, using this mode when
driving down steep off
−road inclines will
help contribute to increased vehicle stabil-
ity.
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 188 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 “(b) Shifting procedure” for further in-
structions. Advice for driving on slippery roads in
“L4” (low speed position) mode
If the four
−wheel drive control switch knob
is in the “L4” and the automatic transmis-
sion selector lever is in the “2” or “3”
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 “L” position of the automatic
transmission selector 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 traction control system if the engine
speed is under 3000 rpm (normally engine
speed is under 3000 rpm when the wheels
get unstuck).

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.
