Electronic stability control

ESC with understeer control
and traction control ASR
Electronic stability control (ESC)
This system helps you to keep control
of the vehicle in critical driving condi-
tions (avoiding an obstacle, loss of grip
on a bend, etc.).
Operating principle
A sensor in the steering wheel detects
the direction selected by the driver.
Other sensors throughout the vehicle
measure the actual direction.
The system compares driver input to
the actual trajectory of the vehicle and
corrects the trajectory if necessary by
controlling the braking of certain wheels
and/or engine power. In the event that
the system is engaged, indicator light
comes on the instrument panel.

Understeer control
This system optimises the action of the
ESC in the case of pronounced under-
steering (loss of front axle road hold-
ing).
Traction Control ASR
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
If you depress the brake pedal con-
tinuously when driving downhill for
long periods, the braking system
may heat up, reducing the quality
of the braking. In this case, use the
engine brake.
Operating principle
The system uses wheel sensors to
constantly measure and compare the
speed of the drive wheels and detect
spinning. If a wheel is starting to slip,
the system brakes automatically until
the drive supplied becomes compatible
with the level of grip under the wheel
again.
The system also adjusts the engine
speed to the grip available under the
wheels, independently of the pressure
exerted on the accelerator pedal.
lit indicates that the ESC system
(with the ASR) is active. When the ESC
is active, there may be a slight vibra-
tion. This is completely normal.
