The ETS (Electronic Traction System) and 4-ETS (four-wheel Electronic Traction System, vehicles with 4MATIC only) are components of the ESP®. The ETS/4-ETS improves the vehicle's ability to utilize available traction, especially under slippery road conditions by applying the brakes to a spinning wheel. Vehicles with 4MATIC also transfer more power to the wheel(s) with traction. When you switch off the ESP®, the ETS/4-ETS is still enabled. To improve the vehicle's traction, switch off the ESP® in driving situations in which it would be advantageous to have the drive wheels spin and thus cut into surfaces for better grip such as: Rwhen Rin Rin driving with snow chains deep snow sand or gravel 1 ESP® switch Switching off the ESP® (except CL 63 AMG) G Warning!
