Make sure your 4WD system works!
Unless you go off-roading all year long, chances are if you own an SUV you don't use your four wheel drive system during the summer. That's why it's important to make sure everything is working correctly before winter starts, even if 4WD doesn't take too much maintenance. A functioning system improves the traction in the snow and ice and your chances of not getting stuck! Make sure to engage your 4WD system to ensure it's working properly. Just remember, even though 4WD works so great in the snow, it doesn't offer any better grip when braking.
