ENGINE IMMOBILISER SYSTEM
SV11007
The 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
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.

(h) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See ºFuel gaugeº onpage 34 for instructions.)
b. The fuel tank cap is not tightened securely. (See ºFuel tank capº on page 65 for instructions.)
c. There is a problem somewhere in your engine electrical system, automatic transmission electrical system or

If it comes on while you are driving in case ºcº., have your
vehicle checked/repaired by your Lexus dealer as soon as
possible.
If this lamp comes on and the engine speed does not increase
with the accelerator pedal depressed down to about the middle
position, there may be a problem somewhere in your electronic
throttle control system.
At this time, if you depress the accelerator pedal more firmly
and slowly, you can drive your vehicle at low speeds. Have
your Lexus checked by your Lexus dealer as soon as possible.
Even if the ab normality 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 ºACCº or ºLOCKº position.
(i) ºABSº Warning Light
The light comes on when the ignition key is turned to the ºONº
position. If the anti±l ock brake system works properly, the light
turns off after a few seconds. Thereafter, if the system
malfunctions, the light comes on again.
When the ºABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system and/or the
traction control system do/does not operate, but the brake
system still operates conventionally.
When the ºABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system and/or the
traction control system do/does not operate so that the wheels
could lock up during a sudden braking or braking on slippery
road surfaces.
If either of the following conditions occurs, this indicates
a malfunction somewhere in the parts monitored by the
warning light system. Contact your Lexus dealer as soon
as possible to service the vehicle.
 The light does not come on when the ignition key is turned
to the ºONº position, or remains on.
 The light comes on while you are driving.
A warning light turning on briefly during operation does not
