antennas, because the radio waves
may affect the operation of such
devices. For the antenna locations
see “ANTENNA LOCATION” on page
32 in this Section.
Users of any electrical medical de-
vice other than implanted pacemak-
ers and implanted cardiac defibrilla-
tors should consult the manufactur-
er of the device for information
about its operation under the influ-
ence of radio waves. Radio waves
could have unexpected effects on
the operation of such medical de-

BATTERY POWER SAVING
Both the vehicle and key transmitters are
always sending signals to each other. To
prevent battery drain, the smart key sys-
tem is automatically deactivated in the fol-
lowing conditions:
If the electronic key is left outside of
the vehicle and within the effective
range of the entry function actuation
area for more than 10 minutes.
If the door lock or unlock operation is
not performed more than 2 weeks.
The key and the vehicle are communicat-
ing even while the vehicle is not being
driven. Do not leave the key near the
vehicle (within 2 m [7 ft.]).
The vehicle battery may drain if the
vehicle is not used for a long period of
time. To prevent battery drain, disconnect
the battery negative (−) terminal or disable
the smart key system. (For details about

form any of the following:
(a) Press the lock button on the front out-
side door handle or trunk open button
while carrying the electronic key.
(b) Perform a wireless remote control op-
eration.
(c) Insert and turn the mechanical key in
the keyhole of the driver’s door.If the electronic key receives strong elec-
tromagnetic waves over a period of time,
the battery can be drastically run down.
You should always keep the following
electrical appliances at least 1 m (3 ft.)
away from the electronic key.
TV
Personal computer
Cellular phone or cordless phone re-
charger unit
Electric light stand
Fluorescent desk light
