Check the condition of the wiper blades. You are responsible for their service life:
– they must remain clean: clean the blades and the windscreen regularly with
soapy water;
– do not use them when the windscreen is dry;
– free them from the windscreen when they have not been used for a long time.
In all cases, replace them as soon as they begin to lose efficiency: approximately
once a year.

In freezing or snowy weather, ensure
they are not stuck to the windscreen
(including the central area located
behind the interior rear-view mirror)
before starting the wipers (risk of
motor overheating).
