why dosen't my truck have wet/snow mode

Hi! This is Bo with Car Genius at RepairPal! Congrats on your purchase! The absence of a wet/snow mode in your 2015 Ford F-150 could be due to different trim levels or specific package options. While some models offer selectable driving modes like Normal, Snow/Wet, Tow/Haul, and Sport, not all versions include these features. Additionally, newer F-150 models may come equipped with advanced traction control systems that automatically adjust to varying road conditions without the need for specific driving modes. If you're looking for enhanced traction in slippery conditions, consider investing in winter tires and practicing safe driving techniques for adverse weather. If you have any other questions feel free to call us at 877-913-1554! We'll be happy to find you a certified shop in your area!
