The HFL system works only with Honda approved
Bluetooth
-enabled cell phones with a hands-free
profile. If you are not sure if a particular cell phone is
compatible with the HFL system, Acura has a dedicated
call center at 888-528-7876 and website www.acura.
com/handsfreelink to answer your questions.
The HFL system allows you to make and receive hands-
free calls. It cannot control the phone’s performance
(call quality and signal strength). For more information
about performance and performance problems, refer to
Dropped Calls.
The most important step in troubleshooting HFL issues
is to identify the model, software version, and wireless
carrier of the phone in question. Not all phones with the
Bluetooth feature and a hands-free profile are
compatible with the HFL system.
Go to handsfreelink.com, and check if the client phone
is approved to work with Honda HFL system.
NOTE:  The lists of approved, archived, and currently testing phones are constantly changing, so make sure you
view them frequently.
 Phones are added as they are approved.
 Phones can be removed from the approved list if a software bug is discovered that makes the phone
incompatible. These phones can be added back to the
approved list if the phone manufacturer corrects the
bug.
 If the software bug is corrected, a new software version is created and may be listed in the Supported
Features section of the phone.
 The software versions that are approved are now being listed in the Software Version field.
 If you cannot access the Acura website, call the HFL call center at 888-528-7876 for further assistance. The
call center is open Monday thru Friday from 6:00 a.m.
to 6:00 p.m. CT; Saturday from 7:00 a.m. to 6:00 p.m.
CT; and Sunday from 8:00 a.m. to 6:00 p.m. CT. To give a voice command to the HFL system, press and
release the HFL TALK button. Always wait for the beep,
then give your command in a clear, natural voice. The
HFL microphone is on the ce
iling by the map lights.
If the HFL system doesn’t recognize your voice
command, you’ll hear ‘‘Pardon.’’ If your command isn’t
recognized a second time, you’ll hear ‘‘Please repeat.’’
If your command isn’t recognized a third time, the HFL
system sends you to its Help menu.
To hear a list of available options at any time, press the
HFL TALK button and say ‘‘Hands-free help.’’
The HFL system may have problems recognizing some
voices. To improve voice recognition:
 Close the windows and the moonroof.
 Set the fan speed to low (1 or 2) or off.
 Adjust the airflow from the center vents down, so that it’s not blowing against the microphone on the ce iling.
 Speak in a clear and natural voice. If the system cannot recognize your command, try speaking louder,
in a deeper tone.
 If the background noise is too loud, you may need to speak louder.
 If you speak with something in your mouth, or your voice is too high, the system may not interpret your
command correctly.
 Find out if the problem is with one person or with everyone who uses the system. If the system has a
problem with only one person’s voice, this is a
system limitation.

Phone Will Not Automatically Connect the
HFL
Incoming Calls
23-366HandsFreeLink System
General Troubleshooting Information (cont’d)
Many reasons for a dropped call are not related to the
HFL system. Here are some causes for dropped calls:
 If the quantity of dropped calls is about the same when the client uses the HFL system versus the
handset, the issue is likely due to the cellular phone
or carrier.
 If the phone is equipped with a retractable antenna, it needs to be extended to maximize signal strength.
 If a client also notices that the calls tend to drop in the same areas, the HFL system may be operating
normally, but something about the area diminishes
cellular coverage to a point where the call drops.
 Hills or m ountains can block or interfere with cellular
signals.
 High-rise buildings, bridges, or other large structures may block or interfere with cellular signals.
 Placing the cell phone in a purse, in a metal briefcase, under the seat, in the glove box, or in the trunk can all
affect signal reception.
 There are coverage gaps in the cellular service. When driving, a call is typically passed from one tower to
another. If the client drives through an area where
there is a coverage gap between towers, the call
drops.
 Electrical storms, heavy rain, or overcast c onditions
interfere with signal strength.
 The cell phone battery’s state of change can affect signal reception. A low battery may reduce the
phone’s ability to boost the antenna’s power and
function properly, especially in low signal strength
areas. Some phone manufacturers trade off signal
transmission and reception strength for battery life.
As the battery weakens, the signal strength may also
weaken. Some cell phones may operate more
effectively than others in low signal strength areas,
especially with a partially charged battery, and
depending on whether or not the retractable antenna
is fully extended (if applicable). On these models,
make sure the antenna is always extended to
maximize signal strength and extend battery life. If a client complains that their cell phone is not
automatically connecting to the HFL system when they
enter the vehicle, do this:
1. Make sure the Bluetooth feature is turned on in the cell phone.
2. Make sure the cell phone is properly painted to the HFL system.
3. Do a soft reset to the cell phone.
4. Check if the phone has an Authorized Connection or Trusted option.
5. Check the battery and signal strength on the cell phone. Pairing a phone requires optimal signal
strength and a nearly full battery.
If a client complains that they cannot receive incoming
calls through the HFL system, see if the call is routing to
the cell phone instead of the HFL system. An easy way
to know if the call is routed to the cell phone is when the
client says, ‘‘I can’t hear the caller, but they can hear me.’’ 1. Make sure the Bluetooth feature is turned on in the cell phone.
2. Make sure the cell phone is paired to the HFL system and linked.
3. Make sure the answer settings in the cell phone are set to multi-key or any-key answer. If the phone is
set to flip open to answer, recommend changing
the setting to Any Key or leaving the phone flipped
open when using the HFL system.
4. Make sure the Auto Answer feature is turned off in the cell phone.
5. Do a soft reset to the phone.
6. Make sure the battery is fully charged and there is adequate signal strength.
7. Ask the client if they have set specific ring tones or ringer IDs to specific contacts. If they have,
recommend using one standard ring tone for all
calls.
8. Make sure the client is pressing the HFL TALK button and not the HFL BACK button or the
navigation buttons.

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.

The SRS is a safety device which, when used with the seat belt, is designed to help protect the driver and front
passenger in a frontal impact exceeding a certain set limit. The system consists of the SRS unit, including safing
sensor and impact sensor (A), the cable reel (B), the driver’s airbag (C), the front passenger’s airbag (D), side airbags
(E), side curtain airbags (F), seat belt tensioners (G), seat belt buckle tensioners (H), side impact sensors (first) (I), front
impact sensors (J), rear safing sensor (K) and side impact sensors (second) (L).
Since the driver’s and front passenger’s airbags use the same sensors, both normally inflate at the same time.
However, it is possible for only one airbag to inflate. This can occur when collision severity is near the threshold for
airbag deployment. In such cases, the SRS system will only deploy airbags when the protection provided by the seat
belt is insufficient.
The front passenger’s weight sensors (M) are part of seat base. The front passenger’s weight sensors detect the
weight on the seat, and send the information to the ODS unit (N). If the total weight is about 30 kg (65 lbs) or less, the
ODS unit sends a signal to the SRS unit to prevent the passenger’s airbag from deploying. When the passenger’s
airbag is disabled, the passenger airbag cutoff indicator on the center panel comes on to alert the driver that the front
passenger’s airbag will not deploy in a front-end collision.
The driver’s seat position sensor (O) is under the driver’s seat on the left side. When the driver’s seat is moved to its
full forward position, the deployment of the driver’s airbag is moderated to decrease its force of impact during a front-
end collision.
