(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.

When the cruise control is being used,
even if you downshift from “D” to “4”,
engine braking will not be enabled be-
cause the cruise control is not cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” on page 195 in this
Section.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
(d) Using “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in “3”, “2” or “L”,
you can start the vehicle in motion as
with the lever in “D”.
With the selector lever in “3” or “2”, the
vehicle will start in first gear and automat-
ically shift to third gear or second gear.
With the selector lever in “L”, the trans-
mission is engaged in first gear.NOTICE
 Be careful not to overrev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:

cause severe automatic transmis-
sion damage from overheating. To
prevent such damage, “4” position
should be used in hill climbing or
hard towing.
(e) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
Vehicles with rear view monitor system—
When the selector lever is shifted into “R”
position with the ignition switch in the
“ON” position, rear view monitor system
will activate. For instructions, see “Rear
view monitor system” on page 302 in Sec-
tion 1 −10. (f) Parking
1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, shift the selector lever to the “P” posi-
tion.
CAUTION
Never attempt to move the selector
lever into “P” position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
If the automatic unlocking operation linked
with the shift position is set, all the side
doors and back door are automatically un-
locked when the selector lever is moved
to the “P” position with the ignition switch
is in the “ON” position. For details, see
“—Automatic door locking and unlocking
functions” on page 25 in Section 1 −2.

(g) Good driving practice
If the transmission repeatedly shifts up
and down between fourth gear and
overdrive when climbing a gentle slope,
shift the selector lever to the “4” posi-
tion. Be sure to shift the selector lever
to the “D” position immediately after-
ward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use “D” position.
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.
(h) 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 button. For instructions, see “If
you cannot shift automatic transmission
selector lever” on page 394 in Section 4.

165
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 speed 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.

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.

NORMAL DRIVING MODE
Leave the system on during ordinary
driving so that it can operate when
needed.
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 trac-
tion control system is in the self −check
mode, but does not indicate a malfunction.
When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
rear wheels. At this time, the slip indi-
cator light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
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.
The brake actuator temperature increases
during continuous operation of the traction
control system, the “AUTO LSD” system,
the vehicle stability control system and
the hill −start assist control system such
as on slippery roads. If the brake actuator
temperature becomes too high while any
of the systems is operating, a buzzer will
start to sound intermittently to indicate
that the traction control system can no
longer operate. In this case, immediately
stop your vehicle at a safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.) At the time the slip indicator light will
come on and the traction control system
temporarily stops operating in order to
protect the brake actuator. (Although the
traction control system does not operate,
there is no problem to continue your driv-
ing.) The system will be automatically re-
stored after a short time and the slip indi-
cator light goes out.

Leave the system on during the ordi-
nary driving so that it can operate
when needed.
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 ac-
tive traction control system is in the self −
check mode, but does not indicate a mal-
function.
When the active traction control system is
operating, the following conditions occur:
The system controls the spinning of the
4 wheels. At this time, the slip indica-
tor light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
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.
The brake actuator temperature increases
during continuous operation of the active
traction control system, the vehicle stabil-
ity control system, the downhill assist con-
trol system and the hill −start assist control
system such as on sli ppery roads. If the
brake actuator temperature becomes too
high while any of the systems is operat-
ing, a buzzer will start to sound intermit-
tently to indicate that the active traction
control system can no longer operate. In
this case, immediately stop your vehicle at
a safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.) At the time, the slip indicator light will
come on and the active traction control
system temporarily stops operating in or-
der to protect the brake actuator. (Al-
though the active traction control system
does not operate, there is no problem to
continue your driving.) The system will be
automatically restored after a short time
and the slip indicator light goes out.
