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 asthey are, this may cause an accident such as fire. Be sure to have the systems of the SRS 
airbag and seat belt pretensioner removed and disposed of by a qualified service shop or by any authorized Lexus dealer or repairer , or another duly qualified and equipped pro- fessional before you scrap your vehicle.
Scrapping of your Lexus
Your vehicle contains batteries and/or accumulators. Do not discard them into theenvironment but cooperate with separate collection (Directive 2006/66/EC).
WARNING
■General precautions while driving 
Driving under the influence: Never drive your vehicle when under the influence of 
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol and certain drugs delay reaction time, impair judgment and reduce coordination, whichcould lead to an accident that could result in death or serious injury. 
Defensive driving: Always drive defensively.  Anticipate mistakes that other drivers or pedestrians might make and be ready to avoid accidents. 
Driver distraction: Always give your full attention to driving. Anything that distracts the 
driver, such as adjusting controls, talking on  a cellular phone or reading can result in a collision with resulting death or serious injury to you, your occupants or others.
■General precaution regarding children’s safety 
Never leave children unattended in the vehicl e, and never allow children to have or use the key. 
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a 
danger that children may injure themselv es by playing with the windows, the moon roof, or other features of the vehicle. In  addition, heat build-up or extremely cold tem- peratures inside the vehicle can be fatal to children.
