Question :Winter programme 850 GLT

Hello Together Unfortunately, my last Volvo 850 2.5-20V GLT automatic lacks the manual and I would have a question regarding the winter program. Now that it is a bit cooler outside ( – 1°C – 0°C) an orange arrow always flashes in the tachometer and you drive very modestly. I believe he then drives in the second or third gear. My question to you is: Is this normal ?? Or is something broken ?? Can you turn it off ?? And if yes, how ?? Thank you for your answers. C hris
