● When the interval wipe function is on, the
intervals are directly proportional to the
speed. This way, the higher the vehicle speed
the shorter the intervals.
● If you stop the vehicle with the windscreen
wiper in position 1 or 2, it will automatically
change to a lower position speed. The set
speed will be resumed when the vehicle pulls
away.
● The windscreen will be wiped again after
approximately five seconds once the "automatic
wash/wipe system" has been activated,
provided the vehicle is moving (drip function).
If you activate the wipers less than 3
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 off and
then on again.
● Do not put stickers on the windscreen in
front of the rain sensor*. This may cause sensor
disruption or faults.
● Depending on the version of the model,
when you engage reverse gear and with the
headlight wiper activated, this can start a
wipe.
