Electronic stability control
(ESC) with understeer control
and traction control
Electronic stability program 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,indi
cator light flashesontheinstru
ment 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
This system helps to limit wheelspin of
thedrivewheelsandtocontroltheve
hicle 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.
Operating faults
When the system detects an operating
fault, the "Check ESC" message and
the and warning lights
appear on the instrument panel. In this
case,theESCandtractioncontrolsys
tem are deactivated.
Consult an approved dealer.
Driver assistance with a trailer
This system helps to maintain control
over the vehicle while using a trailer. It
detects shaking caused by towing a
trailer under certain driving conditions.
Operating conditions
– The towbar must be approved by an
authorised dealer;
– the harness must be approved by an
authorised dealer;
– the towbar must be connected to the
vehicle.
Operating principle
The function stabilises the vehicle by:
– asymmetric braking of the front
wheels to reduce shaking caused by
the trailer;
– brakingofallfourwheelsandlimita
tiononenginetorquetoreducetheve
hicle speed until the shaking has
stopped.
Warning light flashesonthein
strument panel to inform the driver.
Emergency brake assist
This system supplements the ABS and
helpsreducevehiclestoppingdis
tances.
