ECU Lexus ES300 1999 Owner's Manuals (in English)

KEYS AND DOORS
14The engine immobiliser system is a theft prevention
system. When you insert the key in the ignition
switch, the transponder chip in the key's head
transmits an electronic code to the vehicle. The
engine will start, only when the electronic code in
the chip corresponds to the registered ID code for
the vehicle.
The system is automatically set when the key is
removed from the ignition switch. At this time, the
security indicator light at the bottom of the instrument
cluster flashes. When you insert the key in the ignition
switch, the security indicator light goes out and the
system is canceled automatically, which enables the
engine to start.
For your Lexus dealer to make you a new key with
built±in
transponder chip, your dealer will need your key
number and master key. However, there is a limit to the
number of additional keys your Lexus dealer can make
for you. If you make your own duplicate key, you will not be
able to cancel the system or start the engine.
For vehicles sold in U.S.A.

observe the following:
Put luggage or cargo in the trunk when at all possible.
Be sure all items are secured in place.
 Be careful to keep the vehicle level. Placing the

vehicle balance.
 For better fuel economy, do not carry unnecessary
weight.

acceleration or turning, and impair the driver's
control of the vehicle. In an accident they may injure
the vehicle occupants.
