How to use 4wd for Toyota Sienna xle 2007?

The 2007 Toyota Sienna XLE is a front-wheel-drive vehicle and does not come with a four-wheel drive (4WD) option. Instead, it features an all-wheel drive (AWD) system in some models, which automatically distributes power to all four wheels for better traction on slippery surfaces. To utilize the AWD system, simply drive as usual; the vehicle will engage all wheels as needed without any manual input. Always consult the owner's manual for specific details on operating your vehicle's features.
