 HFL TALK button (A): Use this button on the steeringwheel to give commands. Press the button before a
voice command is given.
 HFL BACK button (B): Use this button on the steering wheel to end a call or return to a previous prompt in
the HFL menu. Pressing the button twice or holding it
down returns you to the HFL main menu.
Hard resets clear the saved settings in the cell phone
and restores it to the factory defaults. A hard reset
should be done only as a last resort (see the sell phone
owner’s manual for more information).
This is when your paired phone is actively ready to use
the HFL system. You can pair up to six phones to the
HFL system, but only one phone can be linked at a time.
If two paired phones are in the vehicle, only the phone
that is linked can use the HFL system and functions. The
second phone must be used as a normal handset. A description for linking two Bluetooth devices together.
In this case, you are linking a cell phone with the HFL
system. After the pairing process is complete, the
devices are able to recognize each other and
communicate wirelessly via Bluetooth.
This helps to restore the basic functions of the phone.
To do a soft reset, turn the phone power off, remove
and reinsert the cell phone battery, then turn the phone
back on.
This refers to the software version loaded in the cell
phone. The software version that was tested and
determined to be compatible with the HFL system may
be listed on the HFL website. Not all software versions
are compatible with the HFL system.
These ringtones come factory-installed on the cell
phone.

General PrecautionsSteering-related Precautions
Cable Reel Alignment
24-13
Precautions and Procedures
NOTE: Some systems store data in memory that is lost
when the battery is disconnected. Before disconnecting
the battery, refer to Battery Terminal Disconnection and
Reconnection (see page 22-68).
Please read the following precautions carefully before
servicing the airbag system. If the instructions
described in this manual are not properly followed, or
the airbags could accidentally deploy and cause
damage or injuries. Except when doing electrical inspections, always turn the ignition switch to LOCK (0), disconnect the
negative cable from the battery, then wait at least
3 minutes before starting work.
NOTE: The SRS memory is not cleared even if the
ignition switch is turned to LOCK (0), or the battery
cables are disconnected from the battery.
 Use replacement parts which are manufactured to the same standards and quality as the original parts. Do
not install used SRS parts. Use only new parts when
making SRS repairs.
 Carefully inspect any SRS part before you install it. Do not install any part that shows signs of being
dropped or improperly handled, such as dents, cracks
or deformation.
 Before disconnecting the SRS unit connectors, always disconnect the appropriate SRS parts
connectors.  Use only a digital multimeter to check the system. If it
is not a Honda multimeter, make sure its output is
10 mA (0.01 A) or less when switched to the lowest
value in the ohmmeter range. A tester with a higher
output could cause accidental deployment and
possible injury.
 Do not put objects on the front passenger’s airbag.
 The original audio and navigation system have a coded theft protection circuit. Make sure you have the
anti-theft codes for the audio system or navigation
system (if equipped), then write down the audio
presets before disconnecting the negative cable from
the battery.
 Before returning the vehicle to the client, enter the anti-theft codes for the audio system or navigation
system (if equipped), then enter the audio presets; set
the clock.
 Misalignment of the cable reel could cause an open in the wiring, making the SRS system, remote steering
wheel controls, or the horn inoperative. Center the
cable reel whenever you do the following (see step 6
on page 24-202).
– Installation of the steering wheel
– Installation of the cable reel
– Installation of the steering column
– Other steering-related adjustment or installation
 Do not disassemble the cable reel.
 Do not apply grease to the cable reel.
 If the cable reel shows any signs of damage, replace it with a new one. For example, if the cable reel does
not rotate smoothly, replace it.

B
Seats with side airbags have a ‘‘SIDE AIRBAG’’ label on
the seat-back.
 Clean the seats with a damp cloth. Do not soak the seats with liquid. Do not spray steam on the seats.
 Do not repair a torn or frayed seat-back cover. Replace the seat-back cover if it is damaged.
 After a collision in where the side airbag was deployed, replace the side airbag and the seat frame
with new parts. If the seat-back cushion is split, it
must be replaced.
 Never put aftermarket accessories on the seats (covers, pads, seat heaters, lights, etc.). 1. Disconnect the negative cable from the battery,
when wait at least 3 minutes.
2. Remove the access panel (A) from the steering wheel, then disconnect the driver’s airbag 4P
connector (B) from the cable reel.

Checking Front Passenger’s Weight Sensors
After a Vehicle Collision
24-25
A
10. Shake the related wire harnesses and theconnectors, and look for loose connections, poor
pinfits, and poor grounds.
11. Take a test-drive (quick acceleration, quick braking, and cornering), turn the steering wheel fully left
and right, and hold it there for 5 to 10 seconds. If
the problem recurs, the SRS indicator will come on.
12. If you cannot duplicate the concern, ask the client about the conditions when it occurred, or ask the
client to demonstrate the concern.
13. If you cannot duplicate the intermittent failure, the system is OK at this time. 1. Position the front passenger’s seat to the rearmost
position, adjust the seat-back to the forwardmost
position. Do not move it from this position.
2. Drive the vehicle, accelerate to 20 mph (36 km/h), then stop on level ground.
3. Make sure the ignition switch is in LOCK (0).
4. Connect the HDS to the data link connector (DLC) (A).
5. Turn the ignition switch to ON (II).
6. Make sure the HDS communicates with the vehicle and the SRS unit. If does not communicate,
troubleshoot the DLC circuit (see page 11-204).
7. From the SRS inspection menu, select Seat Weight Sensor, then Misc test, then SEAT OUTPUT CHK
and follow the prompts until the front passenger’s
weight sensor operation check is complete.
