Audio System
Anti-Theft Feature
On U.S. EX models
Your car's audio system will
disable itself if it is disconnected
from electrical power for any
reason. To make it work again, the
user must enter a specific
five-digit code in the Preset
buttons. Because many
combinations are possible using
five digits, making the system
work without knowing the exact
code is nearly impossible.
You should have received two
copies of a card that lists your
audio system's code number and
serial number. It is best to store
one of these cards in a safe place
at home, and to keep the other in
your wallet or purse. In addition,
you should write the audio
system's serial number in this
Owner's Manual. If you should
happen to lose both cards, you
must obtain the code number by
having your Honda dealer contact
Comfort and Convenience Features
American Honda. To do this, he
will need the system's serial
number.
If your car's battery is
disconnected or goes dead, the
audio system will disable itself. If
this happens, you will see "Code"
in the frequency display the next
time you turn on the system. Use
the Preset buttons to enter the
five-digit code. If it is entered
correctly, the radio will start
playing.
If you make a mistake entering the
code, do not start over or try to
correct your mistake. Complete
the five-digit sequence, and then
enter the correct code. You have
three tries to enter the correct
code. If you are unsuccessful in
three attempts, you must then
leave the system on for one hour
before trying again.
You will have to store your
favorite stations in the Preset
buttons after the system begins
working. Your original settings
were lost when power was
disconnected.
