There is ariskofanaccident.
Alwayspay carefulattentiontothe trafficsit-
uationand do not relysolelyonthe distance
warning function.
In particular,the detection of obstaclescan be
impaired in the caseof:
R
dirt on the sensorsoranything else covering
the sensors
R
it is snowing or raining heavily
R
there is interferencefromotherradar sources
R
the possibility of strong radarreflections, for
example, in parkinggarages.
R

motorbike
R

Due to the nature of the system,particularly
complicatedbut non-critical drivingconditions
mayalsocause the system to displayawarning.
If youfailtoadapt your drivingstyle,the dis-
tance warning functioncan neitherreduce the
riskofanaccident nor override the laws of phys-
ics.The distance warning functioncannottake
into account road, weather or trafficconditions.

front, for vehiclespeed, braking in good time
and for staying in your lane.
Following damage to the front end of the vehicle,
