Electronic stability control (ESC) -
general
Stability system ESC (Electronic Stability
Control) helps the driver to avoid skidding and
improves the car's traction.
The activation of the ESC system
during braking may be noticed as a
throbbing sound. The car may
accelerate slower than expected
when the accelerator pedal is depressed.
WARNING
The stability system ESC is supplementary
assistance - it cannot handle all situations
in all road conditions.
The driver always bears responsibility that
the vehicle is driven safely and that appli-
cable road traffic rules and regulations are
followed.
The ESC system consists of the following
functions:
•
Active Yaw Control
•
Spin Control
•
Traction control system
Active Yaw Control
The function checks 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 trans-
fers power from the driving wheel that is spin-
ning to the one that is not.

Selection of level - Sport mode
The ESC system is always activated - it can-
not be deactivated.
However, the driver can
select the Sport mode,
which allows for a more
active driving experience.
Sport mode is selected in
the menu system MY CAR.
For a description of the menu system, see
MY CAR (p. 116).
In Sport mode the system detects whether
the accelerator pedal, steering wheel move-
ments and cornering are more active than in
normal driving and then allows controlled
skidding with the rear section up to a certain
level before it intervenes and stabilises the
car.
If, for example, the driver stops a controlled
skid by releasing the accelerator pedal, then
the ESC system intervenes and stabilises the
car.
With Sport mode, maximum traction is also
obtained if the car has become stuck, or
when driving on a loose surface - e.g. sand or
deep snow.
