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” in this section.)
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.

Vehicles with power door lock sys-
tem—The sliding doors will be locked si-
multaneously when either front door or the
back door is locked with the power door
lock switch or key. If you lock either front
door or the back door with the power door
lock switch or key while the sliding door
is open, the sliding door will be locked
after it is closed. (For instructions, see
“Front doors” or “Back door” in this sec-

ing door. Be careful not to lock your keys
in the vehicle.

push the lock release button and then
close the door.
CAUTION
When closing the sliding door, con-
firm safety of the area around.
Keep the heads, hands and other
parts of the bodies of all occupants
away from the sliding door. Other-
wise, they will be possibly caught
and pinched by the closing door
causing an unexpected serious inju-
ry.
When the vehicle is stopped on a
gradient, the door will slide faster
when opening or closing, so be es-
pecially careful that the passengers
do not get hit or pinched by the
door.
When stopping on a downward
slope, open the door fully while
passengers are getting on or off.
Do not pull the outside handle or
push the lock release button while
the door is open as the door could
suddenly close by itself causing in-
jury.

plying the brakes. Doing so could
