How to Use Active Trac (A-TRAC) on the 2010 Toyota 4Runner
The 2010 Toyota 4Runner comes with a feature called Active Trac or A-TRAC. A-TRAC traction control has the traction benefit of locking front and rear differentials, but with less weight. The ABS (anti-lock braking system) will automatically brake a slipping wheel. This will provide extra torque so that wheels with more traction can continue to push the car along. This automatic feature works seamlessly and the driving experience is not hindered in any way. However, the driver can turn this on or off if he or she wishes to do so.
