GS450h_300h_OM_OM30D53E_(EE)The installation of an RF-transmitter system in your vehicle could affect
electronic systems such as:
Multiport fuel injection system/sequential multiport fuel injection system
Dynamic radar cruise control with full-speed range 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 spe-
cial instructions regarding installation of an RF-transmitter system.
Further information regarding frequency bands, power levels, antenna posi-
tions 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 pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the radio frequency transmit-
ter (RF-transmitter).
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 any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional before you
scrap your vehicle.

For safety drive
Adjust the angle of the seat-
back so that you are sitting
straight up and so that you do
not have to lean forward to
steer. (P. 194)
Adjust the seat so that you can
depress the pedals fully and so
that your arms bend slightly at
the elbow when gripping the
steering wheel. (P. 194)
Lock the head restraint in
place with the center of the
head restraint closest to the top
of your ears. (P. 204)
Wear the seat belt correctly.
(P. 38)
Make sure that all occupants are wearing their seat belts before
driving the vehicle. (P. 38)
Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle’s seat belt. (P.
59)
For safe driving, adjust the seat and mirror to an appropriate posi-
tion before driving.

Make sure that you can see backward clearly by adjusting the
inside and outside rear view mirrors properly. (P. 208, 211)
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 acci-
dent 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
continue driving and take a break immediately.

possible over the hips.

back. Sit up straight and well
back in the seat.
Do not twist the seat belt.
