“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see page 403 in Section
3.
It is not a malfunction even if the needle
of the tachometer, fuel gauge or engine
coolant temperature gauge returns to the
bottom position when the ignition switch is
turned to the “START” position.“ON”—Engine on and all accessories
on.
This is the normal driving position.
It is not a malfunction even if the needle
on the instrument panel may move when
the ignition switch is turned to the “ON”
position.
“ACC”—Accessories such as the radio
operate, but the engine is off.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s

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 ignition
switch in “ON” position).
(a) Selector lever
The shift position is also displayed on the
instrument cluster.
P:Parking, engine starting and key
removal
R: Reverse
N: Neutral
D: Normal driving
(shifting into overdrive possible)
4: Engine braking
(shifting into overdrive not possible)

(b) Normal driving1. Start the engine as instructed in “How to start the engine” on page 404 in
Section 3. The transmission must be in
“P” or “N”.
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, the transmis-
sion will not shift into the overdrive gear
even in the “D” position.
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. (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.

Vehicles with cruise control or dynamic
laser cruise control—When the cruise con-
trol is being used, even if you downshift
from “D” to “4”, engine braking will not be
enabled because the cruise control is not
cancelled.
For ways to decrease the vehicle speed,
see “Cruise control” on page 201 or “Dy-
namic laser cruise control” on page 203
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:
Twowheel drive models “3” 90 km/h (56 mph) . . . . . . . . . .
“2” 58 km/h (36 mph) . . . . . . . . . .
“L” 32 km/h (20 mph) . . . . . . . . . .
Allwheel drive models “3” 87 km/h (54 mph) . . . . . . . . . .
“2” 56 km/h (35 mph) . . . . . . . . . .
“L” 30 km/h (19 mph) . . . . . . . . . .
 Do not continue hill climbing or
hard towing for a long time in the
“3”, “2” or “L” position. This may
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 up1. 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 347 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.
(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 439 in Section 4.

The traction control system automatical-
ly helps prevent the spinning of front
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against front wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.
NORMAL DRIVING MODE
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 just after
the vehicle begins to move. This means
that the traction 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
front 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.

ignition is turned on.
The indicator light comes on with the
normal driving mode while driving.
“VSC” warning light
This light warns that there is a problem
somewhere in the traction control system
or the vehicle stability control system.
The light will come on when the ignition
key is turned to “ON” and will go off after
a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
