Starting and driving
Stability and traction control system
General
The Dynamic Stability and Traction Control
system (STC/DSTC) improves the car’s
traction and helps the driver to avoid
skidding.
A pulsing sound may be noticed during
braking and acceleration when the system is
operating. The car may accelerate more
slowly than expected.
The car is equipped with either STC or DSTC
depending on market. The table shows the
integral functions of the respective systems.
Active Yaw Control
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
acceleration.
Traction control system
The function is active at low speed and
transfers power from the driving wheel that is
spinning to the one that is not.
Reduced operation
System operation during skidding and accel-
eration can be partially deactivated.
Operation during skidding is delayed and so
allows more skidding which provides greater
freedom for dynamic driving.
Traction in deep snow or sand is improved as
acceleration is no longer limited.
Operation 1
– Turn the thumbwheel (1) until the DSTC
menu appears.
DSTC ON means that the system function is
unchanged.
DSTC SPIN CONTROL OFF 2 means that
system operation is reduced.
– Press and hold RESET (2) until the
DSTC menu is changed.
At the same time the symbol illuminates
as a reminder that the system has been
reduced. The system remains reduced until
the engine is next started.
NOTE! DSTC ON 3 is shown for several
seconds in the display each time the engine
is started.
Messages in the information
display
TRACTION CONTROL TEMPORARILY OFF
means that the system has been temporarily
reduced due to excessive brake temperature.
The function is reactivated automatically
when the brakes have cooled.
ANTI-SKID SERVICE REQUIRED means
that the system has been disabled due to a
fault.
