Trajectorycontrolsystems
Anti-slip regulation (ASR)
and dynamic stability
control (DSC)
Theanti-slipregulation(alsoknownastraction
control)optimisestractiontopreventskidding
ofthewheels,byactingonthebrakesofthe
drivingwheelsandontheengine.
The electronic stability control acts on the
brakeofoneormorewheelsandontheengine
tokeepthevehicleonthetrajectoryrequired
bythedriver,withinthelimitsofthelawsof
physics.
Activation
Thesesystemsareactivatedautomatically
eachtimethevehicleisstarted.
Theycomeintooperationintheeventofagrip
ortrajectoryproblem.
Thisisindicatedbyflashingofthis
warninglampintheinstrumentpanel.

Deactivation
Inextremelysevereconditions(deepsnow,
mud,...),ifyouareunabletomoveoff,itmay
beusefultotemporarilydeactivatethese
systemssothatthewheelscanspinfreelyand
allowthevehicletomove.
F Pressthisbutton,locatednearthesteering
wheel.
Iftheindicatorlampinthebuttoncomeson,this
indicatesthatthesesystemsaredeactivated.
Dependingonversion,yourvehiclehasa
systemtohelpdrivingonsnow:intelligent
traction control.
Thissystemdetectssituationsofdifficult
surfaceadhesionthatcouldmakeitdifficultto
moveofformakeprogressondeepfreshsnow
orcompactedsnow.
In these situations, the intelligent traction
controllimitstheamountofwheelslipto
providethebesttractionandtrajectorycontrol
foryourvehicle.
Itisrecommendedthatthesystemsbe
reactivatedassoonaspossible.
Theuseofsnowtyresisstrongly
recommendedonsurfacesofferinglow
levelsofadhesion.
