# Service bulletin ITB11048B

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

SERVICE INFORMATION The rear seat headphones have an "A" channel \(Ach\) and a "B" channel \(Bch\). The channel switch is on the headphone ear pad case. If a person is sitting on the left side \(driver side\) of the vehicle and their headphones are set to Bch, the headphones may have static or intermittently operate \(cut in and out\). OR If a person is sitting on the right side \(passenger side\) of the vehicle and their headphones are set to Ach, the headphones may have static or intermittently operate \(cut in and out\). NOTE: If the headphones are set to the "correct channel" for the seating position, but still have static or do not operate, check the condition of the "AAA" headphone batteries located under the left side headphone cover. Do not replace the headphones for the above issues. See this bulletin for further detail.
