For your information
Main Owners Manual
Please note that this manual applies to all models and explains all equipment, includ-
ing options. Therefore, you may find some explanations for equipment not installed
on your vehicle.
All specifications provided in this manual are current at the time of printing. How-
ever, because of the Lexus policy of continual product improvement, we reserve the
right to make changes at any time without notice.
Depending on specifications, the vehicle sh own in the illustration may differ from
your vehicle in terms of color and equipment.
Accessories, spare parts and modification of your Lexus
A wide variety of non-genuine spare parts and accessories for Lexus vehicles are
currently available in the market. You should know that Toyota does not warrant
these products and is not responsible for their performance, repair, or replacement,
or for any damage they may cause to, or adverse effect they may have on, your
Lexus vehicle.
This vehicle should not be modified with non-genuine Lexus products. Modification
with non-genuine Lexus products could affect its performance, safety or durability,
and may even violate governmental regula tions. In addition, damage or perfor-
mance problems resulting from the modification may not be covered under war-
ranty.
Installation of a mobile two-way radio system
As the installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as the multiport fuel injection system/sequential multiport
fuel injection system, cruise control syst em, anti-lock brake system, SRS airbag sys-
tem and seat belt pretensioner system, be sure to check with your Lexus dealer for
precautionary measures or special instructions regarding installation.

17
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.
Perchlorate Material
Special handling may apply, See www.d tsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.
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.
■General precaution regarding children’s safety
Never leave children unattended in the vehi cle, 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 othe r features of the vehicle. In addition, heat
build-up or extremely cold temperatures inside the vehicle can be fatal to children.
