Electronic Stability Control and Traction Control system
Electronic Stability Control improves
driving stability when necessary,
regardless of the type of road surface
or tyre grip.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually.
Electronic Stability Control operates
in combination with the Traction
Control system. It prevents the driven wheels from spinning.
The Traction Control system is a
component of the Electronic Stability
Control.
Traction Control improves driving
stability when necessary, regardless
of the type of road surface or tyre grip,
by preventing the driven wheels from
spinning.
As soon as the driven wheels starts to spin, engine output is reduced and
