Electronic Stability Control

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 control
indicators b and t extinguish in the
instrument cluster after switching on
the ignition.
When ESC is active b flashes 3 84.

feature tempt you into taking risks

conditions.

slipping on wet, snowy or icy roads,

button t briefly. Control indicator t

Hydraulic brake assist
When the ESC function comes into
action and recognises any
emergency situation requiring hard
braking, it automatically delivers
increased braking pressure to the
wheels.
Active rollover protection
If the vehicle moves in an unstable
manner, this function helps the
vehicle maintain normal stability.
