ENGINE IMMOBILISER SYSTEM
11L024±2
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 r egistered 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 ch\
ip,
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 yo\
u.

KEYS AND DOORS11
You can use up to 4 wireless remote control transmitters for the same vehic\
le.
Contact your Lexus dealer for detailed information.
The wireless remote control transmitter is an electronic component.
Observe the following instructions in order not to cause damage on the
transmitter.

Do not leave the transmitter on the places where the temperature becomes
high such as on the dashboard.
 Do not disassemble it.
 Avoid knocking it hard against other objects or dropping it.
 Avoid putting it in water.
Locking/Unlocking the doors
When you push the ºLOCKº button on the transmitter, all the doors can
be locked from outside the vehicle.
At this time, the parking, tail, side marker and license plate lights flas\
h 1 time
sounding 1 beep. However, when you push the ºLOCKº button with any door
not closed securely, the buzzer sounds for 10 seconds or until all the doors are
closed securely. If the key is in the ignition switch or any of the doors are open,
locking cannot be done.
Make sure all the doors are locked when you leave the vehicle.
When you push the ºUNLOCKº button, the driver's door is unlocked.
Pushing that button once again within 3 seconds from the first push, all
other doors also unlock. At this time, 2 beeps sound. Together with the activation of unlocking, the
parking, tail, side marker and license plate lights flash 2 times. If the key i\
s
in the ignition switch, unlocking cannot be done.
You have 30 seconds to open a door after using the wireless remote unlock
feature. If a door is not opened by then, all the doors will be automat\
ically
locked again.
If the ºLOCKº or ºUNLOCKº switch is kept pressed in, the loc\
king or
unlocking operation is not repeated. Release the button and then push again.11E001±2

IN CASE OF AN EMERGENCY
166
IF YOUR VEHICLE OVERHEATS
If your engine coolant temperature gauge indicates overheating, if you
experience a loss of power, or if you hear a loud knocking or pinging noise,
the engine has probably overheated.
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your emergency flashers.
Put the transmission in ºPº and apply the parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there is no sign of steam or
coolant. Your engine could have been seriously damaged already. Call your
Lexus dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until there
is no steam. Escaping steam or coolant is sign of very high
pressure.
B: If no steam is coming from your engine:
Leave the engine running and turn off the air conditioning. Check the
following.
Is the cooling fan operating?
 Is the coolant in the acceptable range?
 Is the engine drive belt O.K.?
CAUTION
When the engine is running, keep hands and clothing away
from the moving fan and engine drive belt.
 Do not attempt to remove the radiator cap when the engine
and radiator are hot. Serious injury could result from
scalding hot fluid and steam blown out under pressure.
If the cooling fan is not operating or the coolant is not in the acceptabl\
e range,
turn off the engine and call your Lexus dealer.
If both conditions are O.K., after the engine coolant temperature has cooled
to normal, continue driving your vehicle.
If the engine coolant temperature does not cool down, or your vehicle
overheats again, have it checked as soon as possible by your Lexus dealer.

FUEL
Fuel type
Your vehicle must use only unleaded gasoline.
To help prevent gas station mixups, your Lexus has a smaller fuel tank
opening. The special nozzle on pumps with unleaded fuel will fit it, but the
larger nozzle on pumps with leaded gas will not.
At a minimum, the gasoline you use should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5±M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the
three±way catalytic converter/warm up three±way catalytic converter to
lose its effectiveness and the emission control system to function
improperly. Also, this can increase maintenance costs.
Octane rating
Select Octane Rating 87 (Research Octane Number 91) or higher. For
improved vehicle performance, the use of premium unleaded gasoline
with an Octane Rating of 91 (Research Octane Number 96) or higher is
recommended.
Use of unleaded fuel with an Octane Rating or Research Octane Number
lower than stated above will cause persistent heavy knocking. If it is sever\
e,
this will lead to engine damage. If your engine knocks ...
If you detect heavy knocking even when using the recommended fuel, or if\
you hear steady knocking while holding a steady speed on level roads, consu\
lt
your Lexus dealer.
However, now and then, you may notice light knocking for a short time while
accelerating or driving up hills. This is no cause for concern.
Gasolines containing detergent additives
Lexus recommends use of gasolines that contain detergent additives to
avoid build±up of engine deposits.
For further details, ask your Lexus dealer or a local gasoline retailer.
Improved gasolines
The American Automobile Manufacturers Association (AAMA) has
developed a specification of improved gasolines. The AAMA
specification offers optimal fuel information for better vehicle
performance and better protection of your engine.
Lexus recommends the use of gasolines that meet the AAMA specification,
if available, for improved drivability and emission control system.

Gasolines containing MTBE
Gasolines that contain MTBE (Methyl Tertiary±Butyl Ether) are
available in the market. If you use a gasoline mixed with MTBE, make
certain that it does not contain more than 15% of MTBE.
If the use of gasolines containing MTBE causes poor drivability and/or p\
oor
fuel economy, you should stop using them.
Gasolines containing MMT
Some gasolines contain an octane±enhancing additive called MMT
(methylcyclopentadienyl manganese tricarbonyl).
Lexus does not recommend the use of gasolines that contain MMT. If fuels
containing MMT are used, your emission control system may be adversely
affected. The Malfunction Indicator Lamp on the instrument cluster may
come on. If this happens, contact your Lexus dealer for service.
Gasolines containing alcohol
Gasohol is a mixture of gasoline and ethanol. If you use gasohol in your
Lexus, be sure that it is unleaded, has an octane rating no lower than 87
and does not contain more than 10% ethanol. Lexus does not recommend
the use of gasolines containing methanol.
If you use gasoline containing methanol, use only gasoline meeting the
requirements above and also containing less than 5% methanol with
cosolvents and corrosion inhibitors for methanol.
NOTICE
 Do not use gasohol other than stated above. It will cause fuel system
damage or vehicle performance problems.
 If drivability problems are encountered (poor hot starting, vaporizing,
engine knock, etc.), discontinue its use.
 Take care not to spill gasohol during refueling. Gasohol may cause
paint damage.
