Automatic Wipers - CITROEN C4 Handbook

Lighting and visibility
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
To switch on:
► Put the wiper control stalk in the AUTO
position.
► Turn the ring to adjust the sensitivity of the
sensor.
A wiping cycle, accompanied by the display of
a message, confirms that the request has been
taken into account.
► To switch off, put the wiper control stalk in
another position or in the 0 position.

Adjusting the sensitivity
The first position (upper) corresponds to the
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
outside temperature is below +3°C.
– the system works immediately, depending
on the volume of rain detected, if the outside
temperature is above +3°C.
Do not cover the rain/sunshine sensor.
When using an automatic car wash,
switch off the automatic wipers and the
ignition.
In winter, wait until the windscreen is
completely clear of ice before activating the

automatic wipers.

Malfunction
If a fault occurs with the automatic wipers, the
wipers operate in intermittent mode.
Have it checked by a CITROËN dealer or a
qualified workshop.
Special position of the
windscreen wipers
This maintenance position is used while cleaning
or replacing the wiper blades. It can also be
useful, in wintry weather (ice, snow), to release
the wiper blades from the windscreen.
To maintain the effectiveness of the flat
wiper blades, it is advisable to:
– handle them with care.
– clean them regularly using soapy water.
– avoid using them to hold cardboard on the
windscreen.
– replace them at the first signs of wear.
