WARNING
.Always have the doors locked while
driving. Along with the use of seat belts,
this provides greater safety in the event
of an accident by helping to prevent
persons from being thrown from the
vehicle. This also helps keep children
and others from unintentionally opening
the doors, and will help keep out
intruders.
. Before opening any door, always look for
and avoid oncoming traffic.
. Do not leave children unattended inside
the vehicle. They could unknowingly
activate switches or controls. Unat-
tended children could become involved
in serious accidents.

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.
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-
yourself ”section.
For models with a steering wheel lock
mechanism: Because the steering wheel is
locked electrically, unlocking the steering
wheel with the ignition switch in the LOCK
position is impossible when the vehicle
battery is completely discharged. Pay
special attention that the vehicle battery

INTELLIGENT KEY SYSTEM

When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key system’s operating range becomes
narrower, and the Intelligent Key may not
function properly.
The operating range is within 31.50 in (80
cm) from each request switch
*1.
If the Intelligent Key is too close to the door
glass, handle or rear bumper the request
switches may not function.
When the Intelligent Key is within the
operating range, it is possible for anyone
who does not carry the Intelligent Key to
push the request switch to lock/unlock the
doors and open the trunk lid.

DOOR LOCKS/UNLOCKS PRECAU-
TION
. Do not push the door handle request
switch with the Intelligent Key held in
your hand as illustrated. The close
distance to the door handle will cause
the Intelligent Key system to have
difficulty recognizing that the Intelli-
gent Key is outside the vehicle.
. After locking with the door handle
request switch, verify the doors are
securely locked by testing them.
. To prevent the Intelligent Key from
being left inside the vehicle or the trunk, make sure you carry the key with
you and then lock the doors or the
trunk.
. Do not pull the door handle before
pushing the door handle request
switch. The door will be unlocked but
will not open. Release the door handle
once and pull it again to open the door.
