ceiling.
Pause after pressing the navigation TALK button, then give a voice command clearly in a natural
speaking voice. If the system cannot recognize your
command, speak louder.
If the microphone picks up voices other than yours, the system may not interpret your voice commands
correctly.
If you speak a command with something in your mouth, or your voice is too husky, the system may
misunderstand your command.
Compare the system operation with a known-good vehicle. Have more than one person test the system
operation. If the like known-good vehicle performs
the same, if is a characteristic of the system. 1. Turn the ignition switch to ON (II).

Introduction
Checking Cell Phone CompatibilityVoice Control Tips and Improving Voice
Recognition
23-361
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.
