Seat LEON 2019 Owner's Manual page 131

Regularly clean dirt that has become encrus-
ted on the headlights, e.g., remains of insects.
To ensure the headlight washers work cor-
rectly in winter, clean away any snow that
may be present on the jet covers located on
the bumper. If necessary, remove ice with an
anti-ice spray.
Note
The wiper will try to wipe away any ob-
●
stacles that are on the windscreen. The
wiper will stop moving if the obstacle
blocks its path. Remove the obstacle and
switch the wiper back on again.
If you stop the vehicle with the wind-
●
screen wiper in position 1 or 2, it will auto-
matically change to a lower position
speed. The set speed will be resumed when
the vehicle pulls away.
The windscreen will be wiped again ap-
●
proximately 5 seconds after the wind-
screen washer has been activated, provi-
ded the vehicle is moving ("drip" function).
If you activate the wipers less than 3 sec-
onds 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.

Modified behaviour of the rain sensor
Possible causes of faults and mistaken read-
ings on the sensitive surface

Damaged wipers: a film of water on the

damaged blades may lengthen the activa-
tion time, reduce the washing intervals or re-

Insects: insects on the sensor may trigger

Salt on the road: in winter, salt spread on

wipe when the windscreen is almost dry.
Dirt: dry dust, wax, coating on glass (Lotus

effect) or traces of detergent (car wash) may
reduce the effectiveness of the rain sensor or
make it react more slowly, later or not at all.
