Service bulletin ITB22-022

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

SOFTWARE UPDATE POP-UP NOTIFICATION SERVICE INFORMATION The infotainment system in the APPLIED VEHICLES has the ability to update its software through an Over-The-Air (OTA) link. As software updates become available for new features, and/or patches, the software update screen (pop-up) shown in Figure 1 will automatically be displayed. Much like cell phone and computer updates, this is a normal feature which allows the user to choose when an update is downloaded. • It is recommended that while in the retailer inventory and this pop-up appears, that “Yes” is selected to provide the latest software version to the client at delivery. NOTE: If the ignition is turned OFF in the middle of a download, it will automatically restart when the ignition is turned back ON. To avoid risk of death or serious personal injury when updating software: • Park the vehicle in a secure, safe, well-ventilated location that is open to the air and apply the parking brake. • Do not allow people who need assistance, children, and pets to be in the vehicles during the software update. When one of the following is selected: Yes: The pop-up is hidden and the download starts in the background. Later: The pop-up is hidden and displayed again in the next key cycle (after cold start). • To manually start the software update, select: Info > System Information > Software Update > Start Software Update
