The installation of an RF-transmitter system in your vehicle could affect electronic sys- tems such as:
●Multiport fuel injection system/seque ntial multiport fuel injection system
●Dynamic radar cruise control with full-speed range 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 re tailer or Lexus authorized repairer, or any reliable repairer for precautionary measures or special instructions regarding installation of an RF-transmitter system.
Further information regarding frequency ba nds, power levels, antenna positions and installation provisions for the installation of RF-transmitters, is available on request at any authorized Lexus retailer or Lexus author ized repairer, or any reliable repairer.
High voltage parts and cables on the hybrid vehicles emit approximately the same amount of electromagnetic waves as the conventional gasoline powered vehicles orhome electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the reception of the radio frequency transmitter (RF-trans- mitter).
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with th e 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 SRSairbag and seat belt pretensioner removed and disposed of by a qualified service shop or
by any authorized Lexus retailer or Lexus au thorized repairer, or any reliable repairer before you scrap your vehicle.

Scrapping of your Lexus

environment but cooperate with separate collection (Directive 2006/66/EC).

WARNING
■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, whichcould lead to an accident that could result in death or serious 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 atte ntion 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 vehicl e, and never allow children to have or use the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by playing with the windows, the moon roof, or other features of the vehicle. In addition, heat build-up or extremely cold tem- peratures inside the vehicle can be fatal to children.
