Seat Ateca 2016 Owner's Manual page 142

To ensure the headlight washers work cor-
rectly in winter, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an anti-
icing spray.
Note
The wiper will try to wipe away any obstacles
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.

Operation
Rain sensor sensitive surface

The rain sensor controls the frequency of the
windscreen wiper intervals, depending on

the amount of rain . The sensitivity of the
rain sensor can be adjusted manually. Man-

Setting sensitivity level of rain sensor
A
Set control to the right: highly sensi-
–
tive.
Set control to the left: less sensitive.
–
When the ignition is switched off and then
back on, the rain sensor stays on and starts
operating again when the windscreen wipers
are in position and the vehicle is travel-
1
ling at more than 16 km/h (10 mph).
Rain sensor modified behaviour
Possible causes of faults and mistaken read-
›››
ings on the sensitive surface
the rain sensor include:
● Damaged blades: a film of water on the
damaged blades may lengthen the activation
time, reduce the washing intervals or result
in a fast and continuous wipe.
● Insects: insects on the sensor may trigger
the windscreen wiper.
● Salt on roads: in winter, salt spread in the
roads may cause an extra long 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.
● Cracked windscreen: the impact of a stone
will trigger a single wipe cycle with the rain
sensor on. Next the rain sensor detects the
reduction in the sensitive surface area and
adapts accordingly. The behaviour of the sen-
sor will vary with the size of the damage
caused by the stone.
WARNING
The rain sensor may not detect enough rain
to switch on the wipers.
If necessary, switch on the wipers manually
●
when water on the windscreen obstructs visi-
bility.
