(b) Normal driving
1. Start the engine as instructed in “How to start the engine” on page 474 in
Section 3. The transmission must be in
“P” or “N”.
When the front drive control switch knob
is in “4L” (low −speed position, four −wheel
drive), the driving pattern selector setting
has no effect on gear shift timing. (See
“Four −wheel drive system” on page 240 in
this Section for information of the front
drive control lever.)
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
front drive control switch knob is in “4L”
(low −speed position, four −wheel drive), the
transmission will not shift into the over-
drive gear even in the “D” position. (See
“Four −wheel drive system” on page 240 in
this Section for information of the front
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.
AI (Artificial Intelligence) shifting con-
trol—
AI shifting control selects the most
suitable shift range automatically ac-
cording to the driver’s operation and
driving condition.
AI shifting control operates automatical-
ly with the selector lever in the “D”
position. When the lever is moved to
the “S” position, this function will be
cancelled.
Shifting control on the slope:
On inclines, you can drive smoothly
with reduced shifting quantity. On de-
clines, the vehicle will shift down auto-
matically to obtain optimum engine
braking and reduce the driver ’s foot
braking load.
Automatic shifting point change con-
trol:
The most suitable shift range is se-
lected depending on the driver ’s accel-
erator pedal operation and vehicle con-
dition.
(c) Driving in “S” mode
The shift range position can be
changed in “S” mode. When the selec-
tor lever is in the “S” position, the
shift range position can be switched
between “6” (sixth range) and “1” (first
range) by shifting the selector lever to
the “+” (up) or “” (down) position. By
shifting the lever to the “+” (up) posi-
tion and holding it for at least 1 sec-
ond, the highest shift range position
can be obtained. However, it cannot be
changed while cruise control is acti-
vated. When the selector lever is
shifted to the “S” position, shift range
position “4” (fourth range) or “5” (fifth
range) is selected depending on the ve-
hicle speed.

Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of “P” position when the
brake pedal is depressed (with the engine
switch in “ON” position).

1. Start the engine as instructed in “How to start the engine” on page 474 in
Section 3. The transmission must be in
“P” or “N”.
When the front drive control switch knob
is in “4L” (low −speed position, four −wheel
drive), the driving pattern selector setting
has no effect on gear shift timing. (See
“Four −wheel drive system” on page 240 in
this Section for information of the front
drive control lever.)
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
front drive control switch knob is in “4L”
(low −speed position, four −wheel drive), the
transmission will not shift into the over-
drive gear even in the “D” position. (See
“Four −wheel drive system” on page 240 in
this Section for information of the front
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.
AI (Artificial Intelligence) shifting con-
trol—
AI shifting control selects the most
suitable shift range automatically ac-
cording to the driver’s operation and
driving condition.
AI shifting control operates automatical-
ly with the selector lever in the “D”
position. When the lever is moved to
the “S” position, this function will be
cancelled.

lected depending on the driver ’s accel-
erator pedal operation and vehicle con-
dition.
(c) Driving in “S” mode
The shift range position can be
changed in “S” mode. When the selec-
tor lever is in the “S” position, the
shift range position can be switched
between “5” (fifth range) and “1” (first
range) by turning the “S” mode switch
of the selector lever to the “+” (up) or
“” (down) direction. By turning the
“S” mode switch to the “+” (up) direc-
tion and holding it for at least 1 sec-
ond, the highest shift range position
can be obtained. However, it cannot be
changed while cruise control is acti-
vated. When the selector lever is
shifted to the “S” position, shift range
position “4” (fourth range) is selected
automatically.
However, if the selector lever is shifted
to the “S” position when AI shifting
control is being performed, the initial
shift range position may be “3” (third
range). This is because the suitable
shift range is selected depending on
the driving condition.

If there is any malfunction in the brake
system or the engine, “4HI” or “4LO” indi-
cator light blinks and the transfer mode
may not be able to be shifted from “4H”
to “4L”.
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 four−wheel drive system. The traction control system automatical-
ly helps prevent the spinning of the
rear wheels (twowheel drive models)
or 4 wheels (fourwheel drive models)
when the vehicle is started or acceler-
ated on slippery road surfaces.
When the engine switch is turned to the
“ON” position, the system automatically
turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels (twowheel
drive models) or 4 wheels (fourwheel
drive models) cannot be maintained,
even though the traction control sys-
tem is in operation. Do not drive the
vehicle at any speed or in maneuver-
ing conditions which may cause the
vehicle to lose traction control. In si-
tuations where the road surface is
covered with ice or snow, your ve-
hicle should be fitted with snow tires
or tire chains. Always drive at an ap-
propriate and cautious speed for the
present road conditions.

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 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 (two −wheel drive models)
or 4 wheels (four −wheel drive models).
At this time, the slip indicator 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 engine switch is turned
to the “ON” position. If the indicator light
does not come on when the engine switch
is turned on, contact your Toyota dealer. The brake actuator temperature increases
during continuous operation of the follow-
ing systems under conditions such as on
slippery roads.
Traction control system
“AUTO LSD” system
If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the traction control
system can no l onger 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 this time, the slip indicator light comes
on and the traction control system tempo-
rarily stops operating in order to protect
the brake actuator. (Although the traction
control system does not operate, it is not
a problem to continue driving.) The sys-
tem is automatically restored after a short
time and the slip indicator light goes off.XS17010a
and only one of the rear wheels be-
gins to spin,which also may the rear
wheels.TRACTION CONTROL OFF MODE
(twowheel drive mode only)
When getting the vehicle out of mud or
snow, etc., and only one of the rear
wheels begins to spin, it may be benefi-
cial to turn off the traction control sys-
tem. This system which also controls
engine performance may interfere with
the process of freeing the rear wheels.

CAUTION
Do not drive with the “AUTO LSD”
system continuously turned on.
The vehicle stability control system
helps provide integrated control of sys-
tems such as the 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 when the steering wheel is op-
erated abruptly.
The vehicle stability control system is acti-
vated 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 self−check 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 556 in Section 72.)
