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

disposed of by a qualified service shop or by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional before you
scrap your vehicle.
