How does the 2009 highlander 4WD system work?

The 2009 Toyota Highlander features an all-wheel drive (AWD) system that provides enhanced traction by distributing power to all four wheels. It primarily uses a front-wheel drive configuration under normal conditions, but when slippage is detected, the system can automatically transfer power to the rear wheels for improved stability and control. The driver can also select a 4WD lock mode for more challenging conditions, which helps maintain a fixed power distribution between the front and rear wheels. This system allows the Highlander to adapt to various driving conditions seamlessly.
