System Description
Mechanical key
(Including transponder) Immobilizer key
MICU
(Imoes circuit) Mechanical key
Steering lock assembly Immobilizer-keyless
control unit
ECM/PCMTransmitter
(Including
transponder)
The vehicle is equipped with a type VI immobilizer system that will disable the vehicle unless a programmed ignition
key is used.
This system consists of a transponder combined with a keyless transmitter, immob
ilizer-keyless control unit, the MICU
(has built-in imoes unit), immobilizer indicator, and the ECM/PCM.
When the immobilizer key (programmed by the HDS) is inserted into the ignition switch and turned to ON (II), the
immobilizer-keyless control unit sends power to the trans ponder in the ignition key. The transponder then sends a
coded signal back to the immobilizer-keyless control unit which then sends a coded signal to the ECM/PCM and the
MICU (imoes unit). The ECM/PCM and MICU (imoes unit) identify this code signal, then fuel power is supplied.
NOTE: The transmitter is automatically programmed to the vehicle when a transponder is programmed by the HDS.
If the wrong key has been used or the code was not received or recognized by the unit, the indicator will come on for
about 2 seconds, then it will blink until the ignition switch is turned to LOCK (0). When the ignition switch is turned to
LOCK (0), the indicator will blink ten times to signal that the unit has reset correctly, then the indicator will go off.

The navigation system is composed of the navigation unit, the ECM/PCM (vehicle speed signal), the GPS antenna, the
microphone, the voice control switch, the XM receiver, and the climate control unit.
These units communicate with each other on the GA-Net bus.
The vehicle speed pulse is sent by the ECM/PCM. The ECM/PCM receives a signal from the countershaft speed sensor,
then it processes the signal, and transmits it to the speedometer and other systems.

 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.
