DRIVER CORRECTION DEVICES/AIDS (2/4)
Electronic stability control
ESC with understeer control
and traction control ASR
Electronic stability control ESC
(depending on vehicle)
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 the direction se-
lected by the driver and the actual di-
rection of the vehicle and corrects this
as necessary by applying the brakes
selectively and/or acting on the engine
power. Understeer control
This system optimises the action of the
ESC in the case of pronounced un-
dersteer (loss of front axle road hol-
ding).
Traction control ASR
This system helps to limit wheelspin of
the drive wheels and to control the vehi-
cle when pulling away accelerating or
decelerating.
Operating principle
Using the wheel sensors, the system
measures and compares the speed of
the drive wheels at all times and slows
down their over-rotation. If a wheel is
starting to slip, the system brakes au-
tomatically until the drive supplied be-
comes 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.
Warning light
 on the instrument
panel flashes when the function ESC
starts operating (with ASR).
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle beha-
viour to be adapted to suit the dri-
ving conditions.
However, the functions do not take
the place of the driver. They do
not increase the vehicle’s limits
and should not encourage you
to drive more quickly. Therefore,
they can under no circumstances
replace the vigilance or responsibi-
lity of the driver when manoeuvring
the vehicle (the driver must always
be ready for sudden incidents which
may occur when driving).
Operating fault
When the system detects an opera-
ting fault, the
 warning light on
the instrument panel comes on. In this
case, the ESC and the ASR are deac-
tivated.
Please contact an authorised dealer.
