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.
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” in the“8. Maintenance and do-it-
