ELECTRONIC STABILITY PROGRAM: ESP WITH UNDERSTEERING CONTROL
This system helps to keep the
vehicle under control in "critical"
driving situations (avoiding an
obstacle, loss of road holding in a
bend, etc.), and it is complemented
by the "understeer control" system.
This
function
additional aid in case of
critical driving conditions
to enable the vehicle
behaviour to be adapted to suit
the driving conditions.
However, the function does not
take the place of the driver. It
does not increase the vehicle's
limits and should not encourage
you to drive more quickly.
Therefore, it can, under no
circumstances,
replace
vigilance or responsibility of the
driver when manoeuvring the
vehicle (the driver must always
be ready for sudden incidents
which may occur when driving).

driver.
