Although explanation from the user manual makes more sense to me:
Traction Control System
How the system works
The traction control system (TCS) is
designed to prevent wheelspin. This
enables the car to achieve the best possible
grip and, hence, maximum tractive effort,
together with greater stability.
The TCS system uses information from the
ABS system’s wheel sensors to detect
when the front (driving) wheels are rotating
faster then the rear wheels. It then monitors
whether one driving wheel is rotating faster
than the other. If so, the faster wheel is
retarded until both wheels are rotating at the
same speed.
If the two front wheels are rotating at the
same speed but are turning faster than the
rear wheels, the torque from the engine is
reduced to eliminate the difference.
The process continues until all the wheels
are rotating at the same speed.
The advantages of the TCS system become
most apparent when the cohesion between
the front wheels and the road surface is so
low that one or both of the wheels would
lose their grip were the car not equipped
with the TCS, e.g.:
• When the car is pulling away or accelerating
with the front wheels on different surfaces
(e.g. one slippery and one dry). The
TCS then functions like an electronic differential
lock.
• When the car is pulling away or accelerating
on a slippery road, in which case the
TCS eliminates wheelspin. The same
applies when the car is reversing.
• On cornering, if there is a tendency for the
inner front wheel to rotate faster than the
other wheels.
• On overtaking.
