In our recent 14 degree (F) weather, when I unlocked the 2023 XC 60 M5 and sat down to start it there was a message "Battery Save Mode - start for full functionality". I clicked "ok" on the message, started up the car and everything is working just fine. I'm curious if anyone knows which battery it's saving and which features are turned off in save mode. Also, is the battery save mode triggered by a low temperature?
