The engine immobiliser system is a
theft prevention system. When you in-
sert the key in the ignition switch, the
transponder chip in the key’s head
transmits an electronic code to the ve-
hicle. The engine will start, only when
the electronic code in the chip corre-
sponds to the registered ID code for
the vehicle.The system is automatically set when the
key is removed from the ignition switch.
The indicator light will start flashing to
show the system is set.
If any of the following indicator conditions
occurs, contact your Toyota dealer.
The indicator light stays on except
when the theft deterrent system is set-
ting or activating. (See “Theft deterrent
system”.)
The indicator light does not start flash-
ing when the key is removed from the
ignition switch.
The indicator light flashes unsteady. Inserting the registered key in the ignition
switch automatically cancels the system,
which enables the engine to start. The
indicator light will go off.
For your Toyota dealer to make you a
new key with builtin transponder chip,
your dealer will need your key number
and master key. However, there is a limit
to the number of additional keys your
Toyota dealer can make for you.
If you make your own duplicate key,
you will not be able to cancel the sys-
tem or start the engine.
NOTICE
Do not modify, remove or disas-
semble the engine immobiliser sys-
tem. If any unauthorized changes or
modifications are made, the proper
operation of the system cannot be
guaranteed.

SETTING THE SYSTEM
1. Turn the ignition key to the “LOCK” position and remove it.
The indicator light will start flashing when
the key is removed from the ignition
switch. (See “Engine immobiliser system”
for details.)
2. Have all passengers get out of the vehicle.
3. Close the front, sliding and back doors and hood. Then lock all the doors with
the key or wireless remote control
transmitter.
The indicator light will come on when the
front, sliding and back doors and hood are
closed and locked. As the doors are locked, the system will
give you a preparation time of 30 seconds
before the setting, during which the front,
sliding or back doors and hood may be
opened.
Be careful not to unlock any door with the
key or wireless remote control transmitter
during setting. This will cancel the system.
4. After making sure the indicator light starts flashing, you may leave the ve-
hicle.
The system will automatically be set after
the preparation time passes. The indicator
light will flash to show the system is set.
If any of the front, sliding or back doors
or hood is open at that time, the setting
is interrupted until it is closed and locked.
Never leave anyone in the vehicle when
you set the system, because unlocking
from the inside will activate the system. WHEN THE SYSTEM IS SET
Activating the system
The system will give the alarm under the
following conditions:
If any of the front, sliding or back
doors is unlocked or if the hood is
forcibly opened without the key or wire-
less remote control transmitter
If the battery terminal is disconnected
and then reconnected
The indicator light will come on when the
system is activating.
If any of the doors is unlocked without the
key or wireless remote control transmitter
and the key is not in the ignition switch,
all the doors will be automatically locked
again.
After 1 minute, the alarm will automatically
stop and the indicator light will start flash-
ing again.
Reactivating the alarm
Once set, the system cannot be cancelled
without the key or wireless remote control
transmitter. If the front, sliding and back
doors and hood are closed after the alarm
stops, the system automatically resets the
alarm.

This indicates that the fuel filler door
is on the left side of your vehicle.
1. To open the fuel filler door, pull the
lever up.
When refueling, turn off the engine.
CAUTION
Do not smoke, cause sparks or al-
low open flames when refueling.
The fumes are flammable.
When opening the cap, do not re-
move the cap quickly. In hot weath-
er, fuel under pressure could cause
injury by spraying out of the filler
neck if the cap is suddenly re-
moved.
NOTICE
Avoid opening the fuel filler door
when the left side sliding door is fully
opened. Otherwise, the fuel filler door
may be damaged.

NOTICE
Do not put unevenly weighed ob-
jects on the seat and do not stick
sharp objects (needles, nails, etc.)
into the seat.
 When cleaning the seats, do not
use organic substances (paint thin-
ner, benzine, alcohol, gasoline,
etc.). They may damage the heater
and seat surface.
 To prevent the battery from being
discharged, turn the switch on
when the engine is running.
Toyota strongly urges that the driver and
passengers in the vehicle be properly re-
strained at all times with the seat belts
provided. Failure to do so could increase
the chance of injury and/or the severity of
injury in accidents.
Child. Use a child restraint system ap-
propriate for the child until the child be-
comes large enough to properly wear the
vehicle’s seat belts. See “Child restraint”
for details.
If a child is too large for a child restraint
system, the child s hould sit in the rear
seat and must be restrained using the
vehicle’s seat belt. According to accident
statistics, the child is safer when properly
restrained in the rear seat than in the
front seat.
If a child must sit in the front seat, the
seat belts should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may cause death or
serious injury to the child. Do not allow the child to stand up or
kneel on either rear or front seats. An
unrestrained child could suffer serious in-
jury or death during emergency braking or
a collision. Also, do not let the child sit
on your lap. It does not provide sufficient
restraint.
Pregnant woman.
Toyota recommends the
use of a seat belt. Ask your doctor for
specific recommendations. The lap belt
should be worn securely and as low as
possible over the hips and not on the
waist.
Injured person. Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendations.

The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
Nearly full—Needle at “F”
Nearly empty—Needle at “E”
It is a good idea to keep the tank over
1/4 full.
This fuel gauge has a nonreturn type
needle which remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches “E” or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.
