How & When To Use 2WD, AUTO 4WD, 4 HIGH or 4 LOW : A Beginner's Guide

Not sure when to use 2WD, AUTO 4WD, 4HI or 4LO? In this video, I explain what each 4WD mode does, when I use it, and which modes make sense for snow, slippery roads and off-road driving. I demonstrate the system using my 2021 GMC Sierra AT4, but the basic principles apply to many trucks and SUVs equipped with selectable four-wheel drive. 🚙 IN THIS VIDEO: ✔️ When to use 2WD ✔️ When AUTO 4WD makes sense ✔️ When to use 4HI ✔️ When to use 4LO ✔️ Driving in snow and slippery conditions ✔️ Situations where you should NOT use certain 4WD modes ✔️ Real-world examples from my own driving experience One of the biggest areas of confusion is AUTO 4WD versus 4HI. AUTO allows the vehicle to automatically send power to the front wheels when additional traction is needed, while 4HI locks the vehicle into a more traditional four-wheel-drive mode. They serve different purposes, and choosing the right one depends heavily on the road conditions. I also explain where 4LO fits in and why it isn't simply a more powerful version of 4HI. ⚠️ IMPORTANT: Four-wheel-drive systems and manufacturer recommendations can vary by vehicle. Always check your owner's manual for the correct operating procedures, speed limitations and restrictions for your specific vehicle. This video is based on my experience with my 2021 GMC Sierra AT4 and information available for its four-wheel-drive system. 🛒 MY TRUCK, GARAGE & DIY GEAR: https://www.amazon.com/shop/donslife 🌎 DONSLIFE PROJECTS, PRODUCTS & DEALS: https://www.donslife.com 📷 INSTAGRAM:   / donslifechannel   📧 BUSINESS / COLLABORATIONS: donslifechannel@gmail.com DISCLOSURE: Some links in this description may be affiliate links.
