Accessories, spare parts and modification of

A wide variety of non–genuine spare parts and accessories for
Lexus vehicles are currently available in the market. You
should know that Toyota does not warrant these products a n d
is not responsible for their performance, repair or replacement,
or for any damage they may cause to, or adverse effect they
may have on, your Lexus vehicle.
This vehicle should not be modified with non–genuine Lexus
products. Modification with non–genuine Lexus products
could af fect its performance, safety or durability, and may even
violate governmental regulations. In addition, damage or
performance proble m s r e sulting from the modification may not

Spark ignition system of your Lexus
The spark ignition system in your Lexus meets all
requirements of the Canadian Interference–Causing
Equipment Standard.
Installation of a mobile two–way radio system
As the installation of a mobile two–way radio system in your
vehicle could affect electronic systems such as the multiport
fuel injection system/sequential multiport fuel injection system,
cruise control system, anti–lock brake system, SRS airbag
system and seat belt pretensioner system, be sure to check
with your Lexus dealer for precautionary measures or special
instructions regarding installation.
2003 RX300 from Aug. 02’ Prod. (OM48442U)
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your
Lexus contain explosive chemicals. If the vehicle is scrapped
with the airbags and seat belt pretensioners left as they are,
this may cause an accident such as fire. Be sure to have the
system of the SRS airbag and seat belt pretensioner removed
and disposed of by a qualified service shop or by your Lexus
dealer before you scrap your vehicle.
On–pavement and off–road driving tips
This vehicle belongs to the utility vehicle class. Utility vehicles
have a significantly higher rollover rate than other types of
vehicles. This vehicle will handle and maneuver differently
from an ordinary passenger car because it is designed for
off–road use also. In addition, this vehicle has a higher ground
clearance and center of gravity than that of an ordinary
passenger car. This vehicle design feature causes this type of
vehicle to be more likely to rollover. Failure to operate this
vehicle correctly may result in loss of control, accidents or
vehicle rollover causing death or serious injury. B e sure to read
“Off–road vehicle precautions” on page 220 and “Off–road
driving precautions” on page 223.

KEYS
11R105
1
Master keys (black) – These keys work in every lock.
For your Lexus dealer to make you a new key with
built–in transponder chip, your dealer will need it.
2
Sub key (gray) – This key will not open the glove box.
3
Key number plate – Keep the plate in a safe place
such as your wallet, not in the vehicle.
A transponder chip for engine immobiliser system has been
placed in the head of the master and sub keys. These chips
are needed to enable the system to function correctly, so be
careful not to lose these keys. If you make your own duplicate
key, you will not be able to cancel the system or start the
engine.
To protect items locked in the glove box when using valet
parking, leave the sub key with the attendant.
Since the doors can be locked without a key, you should always
carry a spare master key in case you accidentally lock your
keys inside the vehicle.
If you should lose your keys or if you need additional keys,
duplicates can be made by a Lexus dealer using the key
number.
We recommend writing down the key number and storing it in
a safe place.

Flat key
11R089
As a transponder chip is built in its key case, you can start
the engine with this key.
The flat key works in every lock.
A transponder chip for engine immobiliser system has been
placed in the key case of the flat key. This chip is needed to
enable the system to function correctly, so be careful not to lose
this key. If you make your own duplicate key, you will not be
able to cancel the system or start the engine.
Insert your flat key plate in its key case as shown. We
recommend that you always carry this with you for emergency
use. Do not leave it in your vehicle.
Starting the engine using a flat key
11R090
1. Remove the key plate from the key case.
2. Insert the key plate into the ignition switch. The indicator
light keeps flashing.
3. Bring the key case closer to the ignition switch within 10
seconds as indicated by the arrow head. The indicator light
goes out. This means the engine immobiliser system is
automatically canceled. (For details, see “Engine immobiliser
system” on page 12.) Y ou can put the key case away then. You
cannot cancel the engine immobiliser system if 10 seconds
have past a f t e r y o u i n s e rted the key plate. You need to remove
the key plate from the ignition switch and try it again from the
step 2.
4. Start the engine within 60 seconds after the security
indicator light goes out. You cannot start the engine if 60
seconds have past after the security indicator went off. You
need to remove the key plate from the ignition switch and try
it again from the step 2.
NOTICE
Do not let the key case become bent as the key plate
may fall out or become bent also.
The flat key is designed for emergency use only. So
do not use it regularly instead of other master keys.
11L021-2
When using a key containing a transponder chip,
observe the following precautions:
When starting the engine, do not use the key with a
key ring resting on the key grip and do not press the
key ring against the key grip. Otherwise the engine
may not start, or may stop soon after it starts.
