Operation from inside
RETURNING THIRD SEATS
Push one of the switches shown in the
illustrations. The seatback returns to its
original position.
If the indicator light above the switches
flashes three times when the switch is
pushed, the returning operation will not
start.
To continue the operation, do the follow-
ing:1. Operation from outside only—Open the back door when the ignition key is in
“LOCK” or “ACC” and/or the automatic
transmission selector lever is in “P”. 2. Lock the seat legs and push any
switch other than the stowing switch.
Seat operation will stop if any one of
the switches shown in the illustrations
is pushed. At this time the indicator
light above the switches comes on and
a beep sounds for about 10 seconds.
If the engine is started during operating,
the seat operation may also be stopped.
To continue the returning operation, the
seatback must be back to the folded posi-
tion first.
CAUTION
When folding or returning the seats,
observe the following precautions in
order to prevent personal injury:
Make sure that the seat path is
clear before moving the seat. Other-
wise, injury may result from contact
with the seat.
Be careful not to allow hands or
feet to get caught or pinched in the
seat.
When returning the seats to their
original position, make sure the seat
belts are not twisted or caught in the
seatback. It could result in serious
injuries in a sudden braking or a col-
lision.
Do not shift the automatic transmis-
sion selector lever out of “P” with
the ignition key in “ON” during the
operation. Doing so may cause the
vehicle to move and result in serious
personal injury.

seat again.
If the indicator light above the switches
flashes even though there is no object
between the seatback and seat cushion,
contact your Toyota dealer.
If an object is caught between the seat

(d) Charging System Warning Light
This warning light comes on when the
ignition switch is turned to the “ON” posi-
tion, and goes off when the engine is
started.
When there are problems in the charging
system while the engine is running, the
warning light comes on.
NOTICE
When the charging system warning
light comes on while the engine is
running, malfunctions such as the en-
gine drive belt being broken may have
occurred. If the warning light comes
on, immediately stop the vehicle in a
safe place and contact your Toyota
dealer.
(e) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on, or the lamp
comes on while driving, first check the
followings.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp does not go off even after
several trips, contact your Toyota dealer
as soon as possible. If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to “ACC” or
“LOCK” position.

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 the “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)
3, 2: Stronger engine braking
L: Maximum engine braking
Automatic transmission
Selector lever
Shift normally. Shift with the brake pedal
depressed. (The ignition switch
must be in “ON” position.)

(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.

(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 348 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.
