A wide variety of non±genuine spare parts and accessories for

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

system, cruise control system, anti±lock brake system and

for precautionary measures or special instructions regarding
installation.
Scrapping of your Lexus
The SRS airbag device in your Lexus contains explosive
chemicals. If the vehicle is scrapped with the airbags left as
they are, it may cause an accident such as a fire. Be sure to
have the SRS airbag system removed and disposed of by a
qualified service shop or by your Lexus dealer before you
scrap your vehicle.
