2. Remove the discharged battery.
3. Put a new battery with the positive (+)
side up.
Put in the case securely.
NOTICE
Make sure that the positive side of
the controller battery is facing cor-
rectly.
 Do not replace the battery with wet
hands. Water may cause rust.
 Do not touch or move any compo-
nents inside of the controller, or it
may interfere with proper operation.
 Be careful not to bend the electrode
of the controller battery insertion
and that dust or oil does not ad-
here to the transmitter case.
 Close the battery case securely.
After replacing the battery, check that the
controller operates properly. If the control-
ler still does not operate properly, contact
your Toyota dealer.
NOTICE
To ensure correct audio system op-
erations:
Be careful not to spill beverages
over the audio system.
 Do not put anything other than a
cassette tape or compact disc into
the slot.
 The use of a cellular phone inside
or near the vehicle may cause a
noise from the speakers of the au-
dio system. This does not indicate
a malfunction.
RADIO RECEPTION
Usually, a problem with radio reception
does not mean there is a problem with
your radio—it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires can interfere with
AM signals. And of course, radio signals
have a limited range. The farther you are
from a station, the weaker its signal will
be. In addition, reception conditions
change constantly as your vehicle moves.
