Scrapping of your Lexus
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 your Lexus dealer before you scrap your vehicle.
CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired you ability to operate your vehicle. Alcohol and
certain drugs delay reaction time, impair judgment and reduce coordination, which
could lead to an accident that will hurt or kill you, your occupants or others.
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 cigarette
lighter, the windows, the moon roof, or other features of the vehicle. In addition, heat
build-up or extremely cold temperatures inside the vehicle can be fatal to children.
