Ride control systems

Traction Control system

The Traction Control system (TC) is
a component of the Electronic
Stability Control.
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to
spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
control indicator b extinguishes.
When TC is active b flashes.
