4ETS traction control is part of ESP ®
.
4ETS traction control is no longer active above a
speed of approximately 60 km/h.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
awaya nd accelerate on slippery surfaces, e.g. if
the road surface is slippery on one side. In addi-
tion, more drive torque is transferred to the
wheel or wheels with traction.
Traction control remains active if you deactivate
ESP ®
.
