IS250_EE(OM53C51E)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 as
they 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 the
environment but cooperate with separate collection (Directive 2006/66/EC).
CAUTION
■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, which
could 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 vehicle, and never allow children to have or use
the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is also a
danger that children may injure themselves 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.

The main SRS airbag system and Pop Up Hood components are shown above.
The SRS airbag system and Pop Up Hood are controlled by the airbag sensor
assembly. As the airbags deploy, a chemical reaction in the inflators quickly fills
the airbags with non-toxic gas to help restrain the motion of the occupants.
When the Pop Up Hood is activated, a non-toxic gas is released due to a chemi-
cal reaction in the lifters, which causes the pistons to eject quickly and raise the
rear portion of the hood. (Pop Up Hood: →P. 5 4 )
