CAUTION
People with implanted pacemakers or cardiac de-
fibrillators should keep away from the smart ac-
cess system antennas, because the radio waves
may affect the operation of such devices. For the
antenna locations, see “Antenna locations” on
page 28.
 Users of any electrical medical device other than
implanted pacemakers and implanted cardiac de-
fibrillators 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.
 If necessary, the entry functions can be deactivated.
Ask your Lexus dealer for details.

KEYS AND DOORS
10The electronic keys are required to deactivate the engine
immobilizer, and are essential for the engine immobilizer to

system or start the engine.
To protect items when using valet parking, turn the trunk lid
opener main switch to inoperative or lock the glove box if
necessary, and leave the electronic key (with the mechanical
key removed) with the attendant. For details, see “Trunk lid
opener main switch” on page 130.
If you should lose your electronic keys or if you need additional
