# Service bulletin MAS003436

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.

- Type: Service bulletin
- NHTSA id: 10233035
- Published by NHTSA: 2023\-03\-20
- Manufacturer's number: MAS003436

## NHTSA's summary

Rapid Update 589 to restore the correct functionality of the automatic \(A\) and or manual mode \(M\) icons next to recirculation icon via the HVAC display page. After the latest version update of the radio software the recirculation mode automatic \(A\) and manual mode \(M\) icons may have mistakenly disappeared from the screen display. It is therefore necessary to restore the display by writing a new vehicle configuration \(Proxi Alignment\).
