Traction control is part of ESP
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull away and accelerate on slippery surfaces,
for example if the road surface is slippery on
one side. In addition, more drive torque is
transferred to the wheel or wheels with
traction.
Traction control remains active if you

Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
