DRIVER CORRECTION DEVICES/AIDS (3/3)
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
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
Deactivating the ESC
function
In some situations (driving on very wet
ground: snow, mud, etc. or driving with
snow chains fitted), the system may
reduce the engine output to limit wheel-
spin.
If this is not required, it is possible to
deactivate the function by pressing
switch 1.
The warning light
on the instru-
ment panel comes on to warn you of
this.
If you deactivate this function, the trac-
tion control system will also be deacti-
vated.
With the Electronic Stability Program
ESC with understeer control and trac-
tion control providing additional safety,
you are advised not to drive with the
function disabled. Correct this as soon
as possible by pressing the switch 1
again.
Note: The function is automatically re-
activated when the ignition is switched
on, or when the speed exceeds (30
mph) 50 km/h.
Operating principle
A sensor in the steering wheel detects
the direction selected by the driver.
Other sensors throughout the vehi-
cle measure the actual direction. The
system compares driver input to the
actual trajectory of the vehicle and cor-
rects the trajectory if necessary by con-
trolling the braking of certain wheels
and/or engine power. In the event that
the system is engaged, the indicator
light
flashes on the instrument
panel.
Operating faults
When the system detects an operat-
ing fault the warning lights
Ò and
appear on the instrument panel.
In this case, the Electronic Stability
Program ESC with understeer control
and traction control are deactivated.
Please consult an authorised dealer if
these warning lights remain displayed
on the instrument panel after the igni-
tion is switched off and on again
