Electronic Stability Control
The Electronic Stability Control (ESC) improves driving stability when
necessary, regardless of the type of
road surface or tyre grip. It also
prevents the drive wheels from
spinning.As soon as the vehicle starts to
swerve (understeer / oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving stability of the vehicle on slippery road
surfaces.
ESC is operational as soon as the
ignition is switched on and control indicator b extinguishes in the
instrument cluster. A corresponding
message also appears in the Driver
Information Centre 3 103.
