The distance warningfunctioncann otalway s
clearly identify objectsand complex traffic
situations.
In such cases, thedistance warningfunction
may:
R give anunnec essary warning
R not give awarning
There isarisk ofan accident .
Always paycareful attentiontothe traff icsit-
uation anddonot rely solely onthe distance
warning function.
Function Start ingataspeed ofapproximately 4mph
(7 km/ h),the distance warningfunctionwarns
you ifyou rapidly approach avehicle infront .An
inter mittentwarning tonewill then sound, and
the 00BA distance warninglampwilllight upin
the instr ument cluster.
X Brake immediately inorder toincrease the
distance fromthevehicle infront .
or X Take evasive action,provided itis safe todo
so.
Due tothe nature ofthe system, particularly
complicated butnon- critic aldriving conditions
may alsocause thesystem todisplay awarning.
With thehelp ofthe radar sensor system, the
distance warningfunctioncan detect obstacles
that areinthe path ofyour vehicle foranexten -
ded period oftime.
Up toaspeed ofapproximately 44mph
(70 km/ h),the distance warningfunctioncan
also react tostation aryobstacles, suchasstop-
ped orparked vehicles. Autonomous
brakingfunction If
the driver doesnotreact tothe distance warn-
ing signal inacritic alsituation, Active Brake
Assist canassist thedriver withtheautonomous
braking function.
The autonomous brakingfunction:
R gives thedriver moretimetoreact tocritic al
driving situations
R can help thedriver toavoid anaccident or
R can reduce theeffect sof an accident
