Windscreen wiper and rear window wiper systems
Note
●
When the vehicle stops while the wiper is
on, the wiper switches to operating tempora-
rily at the next lower wiping level.
●
If the driver or passenger door is opened
when the vehicle is stationary, the wipers re-
turn to the starting position and are switched
o. If the door is closed or the wiper lever is
moved within a few seconds, the wiper turns
on again.
●
In winter, the service position of the wipers
can be useful to make it easier to lift the wip-
ers o the windscreen when the vehicle is
going to be left stationary ›››page337.
Wiper functions
Automatic rear window wipe
The rear wiper switches on automatically when
the wiper is switched on and reverse gear is en-
gaged. The automatic rear window wiper acti-
vation when engaging reverse gear can be acti-
vated and deactivated in the infotainment sys-
tem, in the vehicle settings menu ›››page40.
Note
The windscreen will be wiped again approx-
imately 5 seconds after the windscreen
washer has been activated, provided the ve-
hicle is moving (“drip” function). If you acti-
vate the wipers less than 10 seconds after
the “drip” function, a new wash sequence will
begin without performing the last wipe. For
the “drip” function to work again, you have to
turn the ignition o and then on again.
Note
The wiper will try to wipe away any obstacles
that are on the windscreen. The wiper will
stop moving if the obstacle is still blocking its
path. Remove the obstacle and switch on the
wiper again.
Rain and light sensor
Fig.106 Sensitive surface of the rain
sensor.
The rain sensor controls the frequency of the
windscreen wiper intervals, depending on the
amount of rain ››› .
Abnormal operation of the rain and light
sensor
The possible causes of anomalies and errone-
ous interpretations in the sensitive surface area
›››Fig.106 of the rain sensor are, among oth-
ers:
●
Damaged wipers: a lm of water on the
damaged blades may lengthen the activation
time, reduce the washing intervals or result in a
fast and continuous wipe.
●
Insects: the impact of insects may cause the
wiper to activate.
●
Salt on the road: in winter, salt spread on
the roads may cause an excessively long wipe
when the windscreen is almost dry.
●
Dirt: dry dust, wax, coating on glass (Lotus
eect) or traces of detergent (car wash) may
reduce the eectiveness of the rain sensor or
make it react more slowly, later or not at all.
Regularly clean the sensitive surface of the rain
sensor ›››Fig.106 (arrow) and check for pos-
sible damage to the wiper blades.
●
Windscreen crack: the impact of a stone will
trigger a single wipe cycle with the rain sensor
on. The rain sensor then detects the reduction
of the sensor surface and adjusts itself. The
behaviour of the sensor may vary depending
on the size of the stone impact.
