CAUTION
If the ignition is switched off with the windscreen wipers active, they com-
plete their wipe before returning to the rest position. Ice, snow and other
obstacles on the windscreen may damage the wiper and the windscreen
wiper motor.
● If necessary, remove snow and ice from the windscreen wipers before
starting your journey.
● Carefully lift the frozen windscreen wipers from the glass. SEAT recom-
mends a de-icer spray for this operation.
CAUTION
Do not switch on the windscreen wipers if the windscreen is dry. Cleaning
with the windscreen wipers while dry can cause damage.
Note
● The windscreen wipers will only function when the ignition is switched
on and the respective bonnet or rear lid are closed.
● The interval wipe speed varies according to the vehicle speed. The faster
the vehicle is moving, the more often the windscreen is cleaned.
● The rear wiper is automatically switched on when the windscreen wiper
is on and the car is in reverse gear. 

Windscreen wiper functions
Windscreen wiper performance in different situations:If the vehicle is at a stand-
still:The activated position provisionally changes
to the previous position.
During the automatic wipe:
The air conditioner comes on for approxi-
mately 30 seconds in air recirculation mode
to prevent the smell of the windscreen wash-
er fluid entering the inside the vehicle.
For the interval wipe:The intervals between wipes vary according
to the speed of the vehicle. The higher the
vehicle speed the shorter the intervals.
Heated windscreen washer jets
The heating only thaws the frozen jets, it does not thaw the water in the
washer hoses. The heated windscreen washer jets automatically adjust the
heat depending on the ambient temperature, when the ignition is switched
on.
Headlight wash/wipe system
The headlight washers/wipers clean the headlight lenses.
After the ignition is switched on, the first and every fifth time the wind-
screen washer is switched on, the headlights are also washed. Therefore,
the windscreen wiper lever should be pulled towards the steering wheel
when the dipped beam or main beam are on. Any incrusted dirt (such as in-
sects) should be cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work correctly 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 ob-
stacle and switch the wiper back on again. 

Rain sensor*
Fig. 66 Windscreen wip-
er lever: adjusting the
rain sensor A
Fig. 67 Rain sensor sen-
sitive 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. Manual wipe ⇒ page 118
Move the lever to the required position ⇒ Fig. 66:
Rain sensor off.
Rain sensor on; automatic wipe if necessary.
Setting sensitivity level of rain sensor
– Set control to the right: highly sensitive.
– 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 1
and the vehicle is travelling at more than 16 km/h (10 mph).
Rain sensor modified behaviour

Lights and visibility
● 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 con-
tinuous wipe.
● Insects: insects on the sensor may trigger the windscreen washer.
● 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 cy-
cle with the rain sensor on. Next the rain sensor detects the reduction in the
sensitive surface area and adapts accordingly. The behaviour of the sensor
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 wind-
screen obstructs visibility.
Note
● Clean the sensitive surface of the rain sensor regularly and check the
blades for damage ⇒ Fig. 67 (arrow).
● To remove wax and coatings, we recommend a window cleaner contain-
ing alcohol. Checking and topping up the windscreen washer reservoir
with water

Recommended windscreen wipers
● For the hottest seasons we recommend summer G 052 184 A1 for clear
glass. Proportions of the mixture in the washer fluid tank: 1:100 (1 part con-
centrate per 100 parts water).
● All year round, G 052 164 A2 for clear glass. Approximate proportion of
the winter mixture, up to -18 °C (0 °F): 1:2 (1 part concentrate per 2 parts
water); otherwise, a 1:4 proportion of mixture in the washer fluid tank.
Reservoir capacity
The reservoir holds approximately 3 - 4 litres; in vehicles with headlight
washer, it is approximately 3 -6 litres.
WARNING
Never mix an unsuitable antifreeze or other similar additives with the
windscreen washer water. A greasy layer may be formed on the wind-
screen which will impair visibility.
● Use clean water with a window cleaner recommended by SEAT.
● If necessary, add a suitable antifreeze to the water in the reservoir.
CAUTION
● Do not mix cleaning products recommended by SEAT with other prod-
ucts. This could lead to flocculation and may block the windscreen washer
jets.
● When topping up service fluids, make absolutely certain that you fill the
fluids into the correct reservoirs. Using the wrong fluids could cause serious
malfunctions and engine damage! Rear vision mirror

● If necessary the right exterior mirror adjustment may need correcting.
Turn the knob to position R.
● In the Easy Connect system the exterior mirrors can be adjusted using
the CAR
button and the function button SETUP.
Tilt function for front passenger exterior mirror*
The mirror can automatically tilt slightly to provide a better view of the kerb
when parking backwards. The control must be in the position R for this fea-
ture to be operational.
The mirror returns to its original position as soon as you drive forwards at
over 15 km/h (10 mph) or switch off the ignition. It also returns to its origi-
nal position if the position of the control is adjusted.
WARNING
Convex or wide-angle* exterior mirrors give a larger field of vision. How-
ever, they make objects look smaller and further away than they really
are. If you use these mirrors to estimate the distance to vehicles behind
you when changing lane, you could misjudge the distance. Risk of acci-
dent!
CAUTION
● If one of the mirror housings is knocked out of position (e.g. when park-
ing), the mirrors must first be fully retracted with the electric control. Do not
readjust the mirror housing by hand, as this will interfere with the mirror ad-
juster function.
● Before washing the vehicle in an automatic car wash, please make sure
to retract the exterior mirrors to prevent them from being damaged. Electri-
cally retractable exterior mirrors must NOT be folded in or out by hand. Al-
ways use the electrical power control.
Note
If the electrical adjustment should fail to operate, both of the mirrors can be
adjusted by hand by lightly pressing the edge of the mirror glass. Anti-dazzle rear vision mirrors
Your vehicle is fitted with an interior rear vision mirror with a
manual or automatic control for anti-dazzle position.

WARNING
In the event that an automatic anti-dazzle rear vision mirror breaks, an
electrolyte fluid may leak. This could cause irritation to the skin, eyes
and respiratory organs. If you come into contact with this liquid, it must
be rinsed with large quantities of water. If necessary, get medial help.
CAUTION
In the event that an automatic anti-dazzle rear vision mirror breaks, an elec-
trolyte fluid may leak. This liquid attacks plastic surfaces. Clean the liquid
with a wet sponge as soon as possible.
Note
● If the light incident in the interior rear vision mirror is obstructed (e.g.
with the sun blind*), the anti-dazzle rear vision mirror with automatic set-
ting will not operate perfectly.
● When the interior lights are on or reverse gear engaged, the rear vision
mirrors do not darken with automatic adjustment for anti-dazzle position. 

Air conditioning
CAUTION
● Switch the air conditioner off if you think it may be broken. This will
avoid additional damage. Have the air conditioner checked by a specialised
workshop.
● Repairs to the air conditioner require specialist knowledge and special
tools. SEAT recommends visiting a SEAT Official Service.
Note
