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 deal er before you scrap your vehicle.
Leak detection pump (for the U.S.A. and Canada)
This pump performs fuel evaporation leakage check. This check is conducted sev-
eral hours after the engine is turned off. You may hear a sound coming from under-
neath the luggage compartment for several minutes, however this does not indicate
a malfunction.
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 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 at tention to driving. Anything that distracts
the driver, such as adjusting controls, ta lking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.
■When children are in the vehicle
Never leave children unattended in the vehicle.
When left unattended, 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 vehi-
cle. In addition, heat build-up or extremel y cold temperatures inside the vehicle can
be fatal to children.
