Accessories, spare parts and modification of
your Lexus

Lexus vehicles are currently available in the market. You
should know that Toyota does not warrant these products and
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 problems resulting from the modification may not
be covered under warranty.
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 twoway 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, dynamic radar 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.
Smart access system with pushbutton start
Users of any electrical medical devices such as implanted
pacemakers should consult the manufacturer of the device for
information about its operation under the influence of radio
waves. Radio waves could have unexpected effects on the
operation of such medical devices. For details, see “Keys” on

Tires and loading on your Lexus
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of steering
ability and braking ability, leading to an accident. Check
the tire inflation pressure periodically and be sure to

details about tire inflation pressure and load limits, see
page 548 and 462.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your
