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.
The Traction Control system
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
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
Electronic Stability Control and the
Traction Control system are
operational after each engine start as
soon as the control indicator
J
extinguishes.
When Electronic Stability Control or
the Traction Control system operates,
J
flashes.
On some occasions, e.g. after
disconnecting the vehicle battery, the
control indicator
J
may illuminate
during some seconds accompanied
by a message in the Driver
Information Centre. This may be
caused by the reset of the steering
angle sensor.
