Lighting and visibility
4To avoid damaging the wiper blades, do not operate the screenwash if the
screenwash reservoir is empty.
Only operate the screenwash if there is no
risk of the fluid freezing on the windscreen
and hindering visibility. During the winter
period, use "very cold climate" rated products.
Never top up with water.
Front intermittent wiping
In Intermittent mode, the driver can adjust the
wiping frequency by turning the ring to one of the
5 available positions.


The first (upper) position corresponds to the
longest time interval between 2 wipes for light
rain.
The last (lower) position corresponds to the
shortest time interval between 2 wipes
for heavy
rain.
A rotation of the ring from a higher position to a
lower position triggers a confirmation wiping.
After the ignition has been switched off for more than 1 minute with the wiper
control stalk in the INT, 1 or 2 position, when
the ignition is switched on again:
–

the system works as soon as the vehicle
exceeds 6 mph (10 km/h), if the outside
temperature is below +3°C.

, if the
outside temperature is above +3°C.
Automatic windscreen wipers
In AUTO mode, the front wipers work
automatically and adapt to the intensity of
precipitation depending on the sensitivity of the
sensor selected.
The rainfall detection function uses a rain/
sunshine sensor located at the top centre of the
windscreen, behind the rear view mirror.
In certain weather conditions (e.g. fog,
frost, snow , projections on salty roads),
the driver may have to return to manual
wiping.
Switching on/off

lowest sensitivity of the sensor.
The last position (lower) corresponds to the
highest sensitivity of the sensor.
The higher the sensitivity, the faster the system
reacts and increases the wiping frequency.
A rotation of the ring from a higher position to a
lower position triggers a confirmation wiping.
After the ignition has been switched off
for more than 1 minute with the wiper
control stalk in the AUTO position, when the
ignition is switched on again:
–

the system works, depending on the
volume of rain detected, as soon as the
vehicle exceeds 6 mph (10 km/h), if the
