Under-inationdetection
Systemwhichautomaticallychecksthepressuresofthetyreswhiledriving.
Theunder-inflationdetectionsystem
doesnotreplacetheneedforvigilance
onthepartofthedriver.
Thissystemdoesnotavoidtheneedto
checkthetyrepressures(includingthe
sparewheel)everymonthaswellas
beforealongjourney.
Drivingwithunder-inflatedtyres
impairsroadholding,extendsbraking
distancesandcausespremature
tyrewear,particularlyunderarduous
condition(highloading,highspeed,
longjourney).
Theinflationpressuresdefinedfor
yourvehiclecanbefoundonthetyre
pressurelabel.
Seethe"Identificationmarkings"
section.
Tyrepressuresshouldbechecked
whenthetyresare"cold"(vehicle
stoppedfor1hourorafterajourneyof
lessthan6miles(10km)atmoderate
speeds).
Otherwise(whenhot),add0.3barto
thepressuresshownonthelabel.
Drivingwithunder-inflatedtyres
increasesfuelconsumption.
Thesystemmonitorsthepressuresinthefour
tyres,oncethevehicleismoving.
Itcomparestheinformationgivenbythefour
wheelspeedsensorswithreference values,
which must be reinitialised every time the
tyre pressures are adjusted or a wheel
changed.
Thesystemtriggersanalertassoonasit
detectsadropintheinflationpressureofone
ormoretyres.
