and implanted cardiac defibrillators should consult the manufacturer of
the device for information about its operation under the influence of radio
waves. Radio waves could have unexpected effects on the operation of
such medical devices.
Ask any authorized Lexus dealer or repairer, or another duly qualified and

tem, wireless remote control and immobilizer system from operating prop-
erly.
