Awd System Basics

How Awd Works
AWD stands for All-Wheel Drive. This system powers all four wheels at the same time. It uses sensors to see how much power each wheel needs. If one wheel slips, the system adjusts power to keep the car steady. The Highlander’s AWD works automatically. It changes power between front and rear wheels without driver input. This helps in rain, snow, or rough roads.
Awd Benefits For Highlander
AWD gives the Highlander better traction. It helps stop slipping on wet or icy roads. It also improves handling on uneven surfaces. The system makes driving safer in bad weather. AWD can also help with towing and carrying heavy loads. It adds stability when you drive on hills or off-road paths. This makes the Highlander a strong and reliable SUV.
