IS300h_EE(OM53B95E)The installation of an RF-transmitter system in your vehicle could affect elec-
tronic systems such as:
Hybrid system
Multiport fuel injection system/sequential multiport fuel injection system
Dynamic radar cruise control system
Cruise control system
Anti-lock brake system
Vehicle dynamics integrated management
SRS airbag system
Seat belt pretensioner system
Be sure to check with any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional for precautionary measures or special
instructions regarding installation of an RF-transmitter system.
Further information regarding frequency bands, power levels, antenna positions
and installation provisions for the installation of RF-transmitters, is available on
request at any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
High voltage parts and cables on the hybrid vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline powered
vehicles or home electronic appliances despite of their electromagnetic shielding.

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.

Make sure that you can see backward clearly by adjusting the inside and
outside rear view mirrors properly. (P. 178, 180)
Adjusting the mirrors
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the
effectiveness of the seat belt and head restraint.
Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat tracks
and stop the seat from locking in place. This may lead to an accident and the
adjustment mechanism may also be damaged.
When driving over long distances, take regular breaks before you start to feel
tired.
Also, if you feel tired or sleepy while driving, do not force yourself to con-
tinue driving and take a break immediately.
