Electronic stability program
(Esc) with understeer control
and traction control
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

flashes on the instrument panel.

Understeer control
This system optimises the action of the
ESC in the case of pronounced under-
steer (loss of front axle road holding).
assistance with side winds
This system optimises the action of the
ESC and also helps to control the vehi-
cle in case of variation of side winds.
It helps maintain the vehicle trajectory
through the use of the brakes.
If the system is triggered, the
warning light appears on the instrument
panel.

These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle behav-
iour to be adapted to suit the driving
conditions.
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 vigi-
lance or responsibility of the driver
when manoeuvring the vehicle (the
driver must always be ready for
sudden incidents which may occur
when driving).
