erly if the wiper blades are worn. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident. Replace

when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratch the glass if wiping takes place when
the windscreen is dry.

the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Cleant he
