Pairing a Cell Phone
23-363
You must pair an approved Bluetooth-compatible
phone to the HFL system before you can make and
receive calls. For a current list of approved phones and
specific phone pairing instructions for each phone, see
Checking Cell Phone Compatibility, go towww.acura.
com/handsfreelink, or call 888-528-7876.
The following procedure works for most phones. If you
cannot pair a phone to the HFL system with this
procedure, refer to the phone’s operating manual, visit
www.acura.com/handsfreelink, or call 888-528-7876.
NOTE:  You cannot pair a phone while the vehicle is moving.
 Your phone must be in Discovery Mode.
 A maximum of six Bluetooth-compatible phones can be paired to the system. 1. With the phone on and the ignition switch in
ACCESSORY (I) or ON (II), press and release the
HFL TALK button. After the beep, say ‘‘Phone setup.’’
The HFL responds, ‘‘Phone setup options are status,
pair, edit, delete, and list.’’
2. Press and release the HFL TALK button. After the beep, say ‘‘Pair.’’ The HFL responds, ‘‘The pairing
process requires operation of your mobile phone.
For safety, only perform this function while the
vehicle is stopped. State a four-digit code for
pairing. Note this code. It will be requested by the
phone.’’
3. Press and release the HFL TALK button. After the beep, say the four-digit code you want to use. This
can be any four-digit number you want. For
example, say ‘‘1, 2, 3, 4.’’ The HFL responds, ‘‘1, 2,
3, 4. Is this correct?’’
4. Press and release the TALK button. After the beep, say ‘‘Yes.’’ The HFL responds, ‘‘HFL is now
searching for a Bluetooth phone. Make sure the
phone you are trying to pair is in Discovery mode.’’
If these steps do not work on the phone you are
pairing, refer to the phone’s operating manual.
5. Follow the prompts on your phone to get it into its Discovery mode. The phone will search for the HFL.
When it comes up, select HandsFreeLink from the
list of options displayed on your phone.
6. When asked by the phone, enter the four-digit code from step 3 into your phone. The HFL responds, ‘‘A
new phone has been found. What would you like to
name this phone?’’
7. Press and release the HFL TALK button. After the beep, say the name you want to use. For example,
say ‘‘Tom’s phone.’’ The HFL responds, ‘‘Tom’s
phone has been successfully paired. Returning to
the main menu.’’

23-368HandsFreeLink System
General Troubleshooting Information (cont’d)
NOTE: This procedure should be used only if HDS is
unavailable.
To run the self-diagnostic function, do the following:
1. Turn the ignition switch to ON (II).
2. Press and hold the HFL BACK button for more than 5 seconds.
3. When the HandsFreeLink system enters the self- diagnostic function, the following will occur.
 If the system has not completed testing for DTCs, the HandsFreeLink system says ‘‘The hands free
system test is in progress’’.
 If there is no DTC, the HandsFreeLink system says ‘‘The hands free system is OK’’.
 If there is any DTC, the HandsFreeLink system says ‘‘The hands free system needs to be
serviced’’.
NOTE:  The self-diagnostic function can only be initiated while the HFL is in its idle state.
 The self-diagnostic function is considered start once the 5 seconds press and hold is detected, and ends
when the units returns to idle state. This cell phone setting forces incoming calls to
automatically be answered by the handset. Disable this
feature on the phone when using the HFL system, as it
may interfere with the HFL system answering incoming
calls. Set the phone setting to:
SendKey
AnyKey
 Multi Key answer
These cell phone settings allow you to select how you
would like to answer an incoming call on the handset.
The answer option in the phone can affect inbound calls
on the HFL system.
This cell phone setting allows the phone to connect
automatically with the HFL system without prompting
the client for permission to connect. In some instances,
it can affect the ability of the phone to properly route
sound to the HFL system.
This cell phone function enables or disables the
Bluetooth application. When using a hands-free device
such as HFL, the Bluetooth application needs to be
enabled.
You need to have the cell phone in Discovery Mode to
allow other devices with Bluetooth capabilities (such as
the HFL system) to find the phone during the pairing
process.
A client gets these ringtones from an outside source,
such as the internet or a mobile phone store.

HFL System Troubleshooting
NOTE:
 You must be able to duplicate the client’s concern to successfully diagnose the problem.
 Always use the client’s phone.
 Make sure the phone is approved and configured correctly. Online, go to www.acura.com/handsfreelink, or call the HFL support desk at 888-528-7876.
1. Connect the HDS to the DLC.
2. Turn the ignition switch to ON (II).
3. Check for DTCs.
Repair the indicated DTCs and recheck.
Go to step 4.
4. Try to duplicate the problem.
Go to step 5.
The system is OK at this time.
5. Pair the phone to a known-good vehicle (same model, year, and trim), and tryduplicate the problem.
Call the HFL support desk at 888-528-7876 to make sure the phone is configured correctly and has the
correct software. If the phone is configured correctly, it is either a characteristic of the HFL system, or a
characteristic of the particular approved phone being used. Explain to your client that this is a system
characteristic. Another phone from the approved phone list may give more favorable results.
Substitute a known-good HandsFr eeLink control unit and recheck. If the problem goes away, replace the
original HandsFreeLink control unit.
Are any DTCs indicated?
