Active chassis - Four C*

Active chassis "Four-C" (Continously
Controlled Chassis Concept), regulates the
characteristics of the shock absorbers so that
the car's driving characteristics can be
adjusted. There are three settings: Comfort,
Sport and Advanced.
Comfort
This setting means that the car is perceived
as being more comfortable on rough and
uneven road surfaces. Shock absorption is
soft and the movement of the body is smooth
and gentle.
Sport
This setting means that the car is perceived
as being more sporty and is recommended
for more active driving. Steering response is
faster than in the Comfort mode. Shock
absorption is harder and the body follows the
road in order to reduce rolling during corner-
ing.
Advanced
This setting is only recommended on very
even and smooth road surfaces.
The shock absorbers are optimised for maxi-
mum roadholding and rolling in bends is fur-
ther minimised.
Operation
Control buttons.
The required chassis setting is selected using
the centre console buttons. The setting used
when the engine was switched off is re-acti-
vated when the engine is next started. The
exception is Advanced - it is restarted as
Sport.

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.
