Vehicle Information

Condition

Call quality using the hands-free function is poor. Additionally, voice-activated functions may be restricted. The call recipient may claim:

^ The driver sounds muffled.

^ The voice of the driver is quiet.

^ The driver's voice is accompanied by background interference.

^ Voice activated commands are not recognized.

Technical Background

Various malfunctions can result from the normal airflow out of center instrument panel vents that are directed upward at the microphones in the roof module, which can limit microphone sensitivity.

Production Solution

New software for the air conditioning/heating control unit is implemented. This update will suspend airflow from the center vents while the voice control system is in use, but it will not adjust the airflow from these vents during a phone call in which the hands-free function is in use.
