IS300h_EE(OM53B95E)The SRS airbag and seat belt pretensioner devices in your Lexus contain explo-
sive chemicals. If the vehicle is scrapped with the airbags and seat belt preten-
sioners 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 professional 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 influ-
ence 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 seri-
ous 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 win-
dows, 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.

It is recommended that children sit in the rear seats to avoid accidental
contact with the shift lever, wiper switch etc.
Use the rear door child-protector lock or the window lock switch to
avoid children opening the door while driving or operating the power
window accidentally.
Do not let small children operate equipment which may catch or pinch
body parts, such as the power window, hood, trunk, seats etc.
Safety information for children

Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt.
CAUTION
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 win-
dows, 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.
