Acura 2011 TL - Manual (Page 376)

Your vehicle’s audio system may
disable itself if it is disconnected
from electrical power for any reason.
To make it work again, you must
enter a specific five-digit code with
the preset buttons. Because there
are hundreds of number
combinations possible from the five
digits, making the system work
without knowing the exact code is
nearly impossible.
You should have received a radio
code card that lists your audio
system’s code and serial numbers. It
is best to store this card in a safe
place at home. In addition, you
should write the audio system’s
serial number in this owner’s manual.
If you lose the card, you must obtain
the code number from your dealer.
To do this, you will need the audio
system’s serial number.
If you make a mistake entering the
code, do not start over; complete the
five-digit sequence, then enter the
correct code. You have ten tries to
enter the correct code. If you are
unsuccessful in ten attempts, you
must then leave the system on for 1
hour before trying again.
The system will retain your AM and
FM presets even if power is
disconnected.
If you have a My Acura account, you
can retrieve the anti-theft code online.
If your vehicle’s battery is discon-
nected or goes dead, the audio
system will disable itself. If this
happens, you will see ‘‘ENTER
CODE’’ in the frequency display
(on the center display on
models with navigation system) the
next time you turn on the system.
Use the preset buttons to enter the
five-digit code. The code is on the
radio code card included in your
owner’s manual kit. When it is
entered correctly, the
radio will start playing.
