IMPORTANT INFORMATION ABOUT YOUR LEXUS
v
Accessories, spare parts and modification of
your Lexus
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 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/laser 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.
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
keep the load limits given in this Owner’s Manual. For
details about tire inflation pressure and load limits, see
pages 468 and 393.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your
Lexus contain explosive c hemicals. If the vehicle is scrapped
with the airbags and seat belt pretensioners left as they are,
this may cause an accident such as a 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.
