WARNING
∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
∙ The Intelligent Key transmits radio waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraf t navigation and com-
munication systems. Do not operate
the Intelligent Key while on an air-
plane. Make sure the buttons are not
operated unintentionally when the
unit is stored for a flight.
The Intelligent Key can operate all the door
locks using the remote control function or
pushing the request switch on the vehicle
without taking the key out from a pocket or
purse. The operating environment and/or
conditions may affect the Intelligent Key
operation.
Be sure to read the following before using
the Intelligent Key.
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 transmits weak
radio waves. Environmental conditions
may interfere with the operation of the In-
telligent Key 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 or a 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 personal
computer. ∙ When the vehicle is parked near a park-
ing meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies de-
pending on the operating conditions, the
battery’s life is approximately two years. If
the battery is discharged, replace it with a
new one.
When the Intelligent Key battery is low, an
indicator illuminates in the vehicle informa-
tion display. For additional information, re-
fer to “Vehicle information display” in the
“Instruments and controls” section of this
manual.
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is lef t near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may be-
come shorter.
For additional information, refer to “Battery
replacement” in the “Do-it-yourself ” section
of this manual.
