Electronic stability control
Electronic stability control (Electronic Stability
Control — ESC) helps the driver to avoid skid-
ding and improves the car’s traction.
The activation of the ESC sys-
tem during braking may be
noticed as a throbbing sound.
The car may accelerate slower
than expected when the accel-
erator 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 applicable
road traffic rules and regulations are followed.
The ESC system consists of the following func-
tions:
•
Active Yaw Control
•
Spin Control
•
Traction control system
•
Engine Drag Control
•
Trailer stability assist
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 acceler-
ation.
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.
Engine Drag Control
Engine Drag Control (Engine Drag Control —
EDC) prevents involuntary wheel locking, e.g.
after shifting down or engine braking when driv-
ing in low gear on slippery road surfaces.
Involuntary wheel locking while driving can,
amongst other things, impair the driver's ability to
steer the car.
Trailer stability assist
* 1
The function of trailer stability assist (Trailer
Stability Assist - TSA) is to stabilise a car with
attached trailer in situations where snaking
occurs. For more information, see the “Driving
with a trailer” section.
NOTE
The TSA function is deactivated if sport mode
is activated.
