DSTC – Stability and traction control system
General information on DSTC
The stability and traction control system, DSTC
(Dynamic Stability and Traction Control) helps
the driver to avoid skidding and improves the
car's traction.
The activation of the system during braking
may be noticed as a throbbing sound. The car
may accelerate slower than expected when the
accelerator pedal is depressed.
Active Yaw Control
04
The function limits the driving and brake force
of the wheels individually in order to stabilise
the car.
Spin Control
The function prevents the driving wheels from
spinning against the road surface during accel-
eration.
Traction control system
The function is active at low speed and trans-
fers power from the driving wheel that is spin-
ning to the one that is not.

Operation
Reduced operation
System operation during skidding and accel-
eration can be reduced. Operation during skid-
ding is delayed and so allows more skidding
which provides greater freedom for dynamic
driving. Traction in deep snow or sand is
improved as traction is no longer limited.
1. Turn the thumbwheel (1) until the
menu is shown.
DSTC-ON
means that the
system function is unchanged.
DSTC spin control OFF

tem operation is reduced.
2. Press and hold RESET (2) until the

riorate if the function is reduced.
