Instruments and controls2-23

WARNING
.Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufacturer
for the possible influences before use.
. The Intelligent Key transmits radio
waves when the buttons are pushed.
The FAA advises that the radio waves
may affect aircraft navigation and com-
munication systems. Do not operate the
Intelligent Key while on an airplane.
Make sure the buttons are not operated
unintentionally when the unit is stored
during a flight.
The Intelligent Key system can operate all
the doors and the trunk lid using the
remote controller function or pushing the
request switch on the vehicle without
taking the key out from a pocket or purse.
The operating environment and/or condi-
tions may affect the Intelligent Key system
operation.
Be sure to read the following before using
the Intelligent Key system.
CAUTION
.Be sure to carry the Intelligent Key with
you when operating the vehicle.
. Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicat-
ing with the vehicle as it receives radio
waves. The Intelligent Key system trans-
mits weak radio waves. Environmental
conditions may interfere with the operation
of the Intelligent Key system under the
following operating conditions.
.When operating near a location where
strong radio waves are transmitted,
such as a TV tower, power station and
broadcasting station.
. When in possession of wireless equip-
ment, such as a cellular telephone,
transceiver, and CB radio.
. When the Intelligent Key is in contact
with or covered by metallic materials.
. When any type of radio wave remote
control is used nearby.
. When the Intelligent Key is placed near
an electric appliance such as a perso- nal computer.
. When the vehicle is parked near a
parking meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key
function or use the mechanical key.
Although the life of the battery varies
depending on the operating conditions,
the battery’s life is approximately 2 years.
If the battery is discharged, replace it with
a new one.
When the Intelligent Key battery is almost
discharged, insert the Intelligent Key into
the Intelligent Key port to start the engine.
Replace the discharged battery with a new
one as soon as possible. For more details,
see “Push-button ignition switch” (P.5-9).
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and
personal computer, the battery life may
become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery repla-
cement” (P.8-26).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For
