4-wheel Electronic Traction System (4-ETS)

4-wheel Electronic Traction System (4-ETS)

For optimum traction, even in slippery conditions, 4MATIC all-wheel drive incorporates our advanced 4-wheel Electronic Traction System. 4-ETS can help get you going even if three wheels lose their grip. Sensors at each wheel monitor traction based on wheel speeds. If one or more wheels start to slip, 4-ETS individually brakes the slipping wheels to maintain the flow of torque to the wheels with grip. Even if only one wheel has grip, 4-ETS can help get you going and stay in control.

Disclaimer

No system, regardless of how advanced, can overcome the laws of physics or correct careless driving. Please always wear your seat belt. Performance is limited by available traction, which snow, ice and other conditions can affect. Always drive carefully, consistent with conditions. Best performance in snow is obtained with winter tires.
