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

Volvo Car USA LLC on behalf of Volvo Car Corporation, has decided to launch Active Service Action A10091 on certain Model Year 2021 XC40 Recharge vehicles. When using the ?Care Key?, there are some settings that are faulty and not possible to change from the Infotainment Head Unit \(IHU\) menu. Volvo has identified that when using the Care Key, some functions will not work as intended as some settings are incorrect. Below settings are affected when you use the Care Key: ? Driver Information Module \(DIM\) = Always km/h and Celsius. Not possible to select mph and Fahrenheit. ? Unlock/lock feedback = Mirrors will always fold, no light indication ? Trip information in DIM = Always none \- Cannot show average speed, fuel consumption etc. ? Interior light = Always off in door seal and foot area, when you are driving. ? Welcome light = Always on \- When you unlock the car. The corrective action is to download a Total Upgrade software. A10091 affects 880 vehicles in the U.S. An additional benefit to this software is that it enables the XC40 P8 Recharge to now be provisioned to the Volvo\-On\-Call app.
