Introduction
The HFL system works only with Honda approved Bluetooth(R)-enabled cell phones with a hands-free profile. If you are not sure if your cell phone is compatible with the HFL system, Honda has a dedicated call center at 888-528-7876 and web site handsfreelink.honda.com, to answer your questions. You can also contact the call center for information about cell phone software versions and settings.
The HFL system allows you to make and receive hands-free calls. It cannot control the cell phone's performance (call quality and signal strength). For more information about performance and performance problems, refer to Dropped Calls.
Always call the HFL call center first, not Tech Line because the HFL call center has the latest information about cell phone software versions, settings, and other issues.
Most HFL complaints are due to pairing, configuration, or compatibility issues. Contact the Honda call center before replacing the HandsFreeLink control unit.
The call center is open Monday thru Friday from 6:00 a.m. to 6:00 p.m. CST; Saturday from 7:00 a.m. to 6:00 p.m. CST; and Sunday from 8:00 a.m. to 6:00 p.m. CST.
Checking Cell Phone Compatibility
The most important step in troubleshooting HFL issues is to identify the customer's cell phone model, the software version, and the cellular carrier that experiences the HFL problem. Not all cell phones with the Bluetooth feature and a hands-free profile are compatible with the Honda HFL system.
Go to handsfreelink.honda.com or call the Honda's dedicated call center at 888-528-7876, and check if the customer's cell phone is approved to work with the Honda HFL system.
NOTE:
- These approved and currently testing cell phone model lists are constantly changing, so make sure you view them frequently.
- Cell phones are added as they are approved.
- Cell phones can be removed from the approved list if a software bug is discovered that makes the cell phone incompatible. There cell phones can be added back to the approved list if the cell 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 cell phone. If you have trouble finding the cell phone's software version, you can call the HFL call center at 888-528-7876.
- The Honda web site now includes the software versions that are tested and approved. When software versions are listed, you need to know which version is loaded on the cell phone to help you troubleshoot the customer's complaint. If you cannot access the Honda web site, call the Honda's dedicated call center at 888-528-7876 for further assistance.
Voice Tag Tips
HFL voice control and voice recognition is not supported in this model. The HFL system stores a simple voice tag for the Speed Dial. But HFL is controlled by using the navigation voice recognition system. If you want a complete description of this system, please refer to the Owner's Manual.
Navigation Through HFL Menus
To skip a voice prompt, press and release the TALK button (A) while the HFL system is speaking. The system beings listening for your next voice command.
To go back a step in a voice command sequence, press and release the BACK button (B), or press the TALK button and say "Go back." If you do not say anything while the HFL system is listening for your voice command, it times out and stops voice recognition. The next time you press and release the TALK button, the HFL system begins listening from the point it timed out.
If you've finished or want to stop a voice command sequence at any time, press and release the BACK button, or press and release the TALK button, wait for the beep, and say "Cancel." The next time you press and release the PICK-UP button (C), the HFL system begins from its main menu. To avoid keeping the audio system muted, press and release the BACK button when you are finished.
Pairing a Cell Phone
You must pair an approved Bluetooth-compatible cell phone to the HFL system before you can make and receive calls. For a current list of approved cell phones and specific cell phone pairing instructions for each cell phone, see Checking Cell Phone Compatibility, go to handsfreelink.honda.com, or call the Honda's dedicated call center at 888-528-7876.
The following procedure works for most Honda approved cell phones. If you cannot pair your cell phone to the HFL system with this procedure, refer to your cell phone's operating manual, the vehicle's Owner's Manual, visit handsfreelink.honda.com, or call the Honda's dedicated call center at 888-528-7876.
NOTE:
- You cannot pair a cell phone while the vehicle is moving.
- Your cell phone must be in its Discovery mode.
- A maximum of six approved Bluetooth-compatible cell phones can be paired to the system.
With Navigation
The commands for pairing the cell phone can either be selected using the interface dial or by using the voice recognition system (TALK and BACK buttons).
NOTE: The HFL system can pair up to six approved cell phones. If you try to pair a seventh cell phone, a message appears that prompts you to delete one of your existing cell phones.
1. Turn the ignition switch to ACCESSORY (I), and make sure the cell phone you are pairing is on and in its discovery mode.
2. Press the INFO button, and turn the interface dial to select Cellular Phone, then press ENTER.
3. Move the interface dial down to select Phone Setup.
4. Select Setup Bluetooth phone, and press Enter.
5. Select Pair Phone, then press enter.
6. When a four-digit pass key number appears on the screen, wait until prompted by the cell phone, then enter the pass key into your cell phone.
7. Once the cell phone is successfully paired, the screen displays "The pairing was successful."

Pairing Troubleshooting
Many pairing issues are resolved by altering the customer's cell phone settings. Call the Honda's dedicated call center at 888-528-7876 after you have duplicated the problem.
If you cannot get an approved HFL cell phone to pair, call the Honda's dedicated call center at 888-528-7876, or go online to handsfreelink.honda.com.
Bluetooth feature settings must be turned on. Phone manufacturers set the default to disable Bluetooth features to conserve battery life. Cell cell phones may provide procedures to "Temporary Power On Bluetooth", or "Power On Bluetooth." Turn the Bluetooth feature on, pair the cell phone to the vehicle, and confirm the cell phone is linked. Do this by turning the phone off and back on. Make or receive a call to confirm the cell phone is successfully paired.
When the cell phone's Bluetooth feature is on, other handsfree accessories such as earpieces or headsets may automatically reconnect to the cell phone when you turn on the accessory or move it within range of the cell phone.
This results in the cell phone not connecting to the HFL system when the customer enters the vehicle. You must unlink the hands-free accessory from the cell phone before the HFL system can reconnect.
Some cell phones have an Auto Answer setting that functions with a headset. This setting must be turned off or the HFL system cannot accept any incoming calls. When this setting is on, it blocks the HFL system from answering the call, and the call goes to voice mail. This can cause the customer to think that the cell phone is not paired properly.
Pairing Checks
For more information about pairing, refer to the cell phone operating manual, or go to handsfreelink.honda.com.
1. Is the cell phone compatible with the HFL?
2. Is the Bluetooth feature turned on?
3. Is the customer using the HFL buttons, not the navigation buttons (if applicable), when pairing?
4. Is the cell phone battery fully charged, and is there good signal strength when pairing?
5. Do a soft reset on the cell phone.
6. If the customer is trying to pair a Blackberry(R) or Palm TreoTM device, make sure the customer uses the shift key when entering the pass code. If the shift key is not pressed, the customer may be entering letters. The HFL does not recognize letters.
Dropped Calls
Customers may perceive dropped calls as being an HFL system fault, but most dropped calls are resultant from cell phone and cell phone carrier issues. The HFL system does not directly handle the cell phone signal. It allows the cell phones to transmit the cell phone audio over the vehicle's audio system.
Many dropped calls issues can be resolved by changing the customer's cell phone settings. For help on approved HFL settings, call the Honda's dedicated call center at 888-528-7876, or go online to handsfreelink.honda.com.
Always confirm with the customer if the number of dropped calls is higher while using the HFL system as opposed to using the cell phone only. Customers often confuse problems with their cell phone or carrier as a problem with the HFL system. The HFL system cannot control or determine:
- Cellular connection quality
- Signal strength
- Cellular coverage
- Ambient weather conditions that affect cellular signals
When a customer complains about dropped calls, ask questions about when or where the calls are dropped, such as:
- Do you drive the same route on a regular basis?
- Does the call drop in the same location?
- Where do you keep your cell phone?
- Have you compared the number of dropped calls using the HFL versus making calls from the handset?
- Does your cell phone have an antenna that needs to be extended?
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 customer uses the HFL system versus the handset, the issue is likely due to the cellular phone or carrier.
- If the cell phone is equipped with a retractable antenna, it needs to be extended to maximize signal strength.
- If a customer 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 mountains 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 customer drives through an area where there is a coverage gap between towers, the call drops.
- Electrical storms, heavy rain, or overcast conditions interfere with signal strength.
- The cell phone battery's state of change can affect signal reception. A low battery may reduce the cell phone's ability to boost the antenna's power and function properly, especially in low signal strength areas. Some cell 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.
Phone will not Automatically Connect the HFL
Call the Honda's dedicated call center at 888-528-7876 after you have duplicated the problem.
If a customer 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 paired to the HFL system.
3. Do a soft reset to the cell phone.
4. Check if the cell phone has an Authorized Connection or Trusted option.
5. Check the battery and signal strength on the cell phone. Pairing a cell phone requires optimal signal strength and a nearly full battery.
Incoming Calls
Call the Honda's dedicated call center at 888-528-7876 after you have duplicated the problem.
If a customer 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 customer 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 cell phone is set to flip-open to answer, recommend changing the setting to Any Key or leaving the cell phone flipped open when using the HFL system.
4. Make sure the Audio Answer feature is turned off in the cell phone.
5. Do a soft reset to the cell phone.
6. Make sure the battery is fully charged and there is adequate signal strength.
7. Ask the customer if they have set specific ring tones or ringer IDs to specific contacts. If they have, recommend returning them to a standard ring tone for all calls.
8. Make sure the customer is pressing the PICK-UP button (A).
Outgoing Calls
Call the Honda's dedicated call center at 888-528-7876 after you have duplicated the problem.
If a customer says that they cannot place a call using the HFL system, ask if the call was initiated through the HFL system or the cell phone itself.
If the call is placed by the HFL system:
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 customer is pressing the TALK button (A) before each command and going through the calling process correctly.
4. Make sure the customer is pressing the PICK-UP button (B).
5. Check if the cell phone has an Authorized Connections or Trusted option.
6. Do a soft reset to the cell phone.
If the call is placed by the cell phone:
- With navigation system; The call will remain on the handset until you transfer it over to the HFL system. To continue the call on the HFL system, you must use the Transfer command by selecting "Transfer." The customer can now continue the call using the HFL system.
- Without navigation system; By default calls made from the handset will transfer to the HFL system. If Auto-transfer is turned "off " calls will remain on handset. To continue or the HFL system, press the HFL TALK button and say "Transfer."
