When the ignition is switched off and then

Malfunction of the rain and light sensor
Some examples of possible causes of faults
and mistaken readings on the reference sur-

of the rain and light sen-
sor:
●
Wiper blades in poor condition: the pr
es-
ence of a film or strips of w
at
er caused by
damaged blades may cause the windscreen
wipers to be slower taking effect, shorten
wiping intervals or cause wiping to be fast
and continuous.
●
Insects: mosquitoes impacting the wind-
screen can activate the windscreen wiper.
●
Traces of salt: in winter, the windscreen
wiper may work for longer than usual due to
the presence of traces of salt on the almost
dry windscreen.
●
Dirt: the presence of dry dust, wax, coating
films (Lotus effect) or traces of detergent (car
wash) etc., on the windscreen may cause the
rain and light sensor to be less sensitive, react
more slowly, later or not at all.
●
Crack on the windscreen: the impact of a
stone will trigger a single wipe cycle if the
rain and light sensor is activated. Subse-
quently, the sensor detects the reduction in
the reference surface area and adapts ac-
cordingly. The behaviour of the sensor will
vary with the size of the damage.
Clean the reference surface area of the rain
and light sensor
1
regularly and check that
the windscr
een wiper bl
ades hav
e not been
damaged.
CAUTION
The rain and light sensor does not always
detect rainf
all with sufficient accuracy so
does not always switch on the windscreen
wiper at the right moment.
●
If necessary, switch on the windscreen
wipers manually when water on the wind-
screen obstructs visibility.
Note
We recommend the use of a glass cleaning
product containing al
cohol to remove
traces of wax or polish.
