Features and controls
NOTE
The F.A.S.T.-key uses weak electromagnetic waves.
In cases such as the following, operation may be improper
or unstable.
• The vehicle is near a facility that emits strong electro-
magnetic waves, such as a TV transmitting tower, a
power station, a radio station or an airport
• The key is carried together with other communication
devices such as cellular phones or radios, or electrical
appliances such as computers
• The F.A.S.T.-key touches or is covered by a metal object
• A keyless entry system is being used nearby
• The battery of the F.A.S.T.-key is run down
3
• The vehicle is in a location with strong electromagnetic
waves or noise
Use the emergency key in such circumstances.
Refer to "To operate without using the F.A.S.T.-key" on
page 3-29.
The F.A.S.T.-key is constantly performing reception oper-
ations in its communication with the vehicle. This means
that the battery is always running down, regardless of how
often the F.A.S.T.-key is used. The battery life is about 1
to 3 years, depending on the usage conditions.
Since the F.A.S.T.-key is constantly performing reception
operations, the reception of strong electromagnetic waves
can accelerate the running down of the battery. Do not
place near to electrical appliances such as televisions or
computers.

Operating range of the F.A.S.T.-key
When a person enters the operating range of the F.A.S.T.-key
while carrying the F.A.S.T.-key and presses the driver's or
front passenger's door lock/unlock switch, the liftgate LOCK
switch or the liftgate OPEN switch, verification of the ID code
is performed.
The doors and the liftgate can only be locked and unlocked, the
engine can only be started and the operation mode can only be
changed when the ID codes of the vehicle and F.A.S.T.-key
match.
NOTE
When the battery of the F.A.S.T.-key has run down or
there are strong electromagnetic waves or noise in the
area, the operating range could decrease or operations
could become unstable.
