Electronic stability
control
Electronic Stability Control (ESC
33
) helps the
driver to avoid skidding and improves the car's
traction.
The driver display shows this
symbol when the system is
engaged.
Braking from the system may
be heard as a pulsing sound,
and the car may accelerate
more slowly than expected when applying the
throttle.
The system consists of the following subfunc-
tions:
• Stability function
34
• Spin control and traction control system
• Engine Drag Control
• Trailer Stability Assist
Stability function
34
The function checks the driving and brake force
of the wheels individually in order to stabilise the
car.
Spin control and traction control system
The function is active at low speed and brakes
the drive wheels that spin so that additional trac-
tion shall be transferred to the drive wheels that
are not spinning.
The function can also prevent the driving wheels
from spinning against the road surface during
acceleration.
Engine Drag Control
Engine Drag Control (EDC
35
) can prevent invol-
untary wheel locking, e.g. after shifting down or
engine braking when driving in low gear on slip-
pery road surfaces.
Involuntary wheel locking while driving can,
amongst other things, impair the driver's ability
to steer the car.
Trailer Stability Assist
36
The function of Trailer Stability Assist (TSA
37
) is
to stabilise a car with a trailer connected in sit-
uations where the combination has begun to
fishtail.
