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. 
Windscreen wipers service position
Fig. 65 Wipers in service
position
The wiper arms can be raised when the wipers are in service position
⇒ Fig. 65. To place the windscreen wipers in the service position, proceed
as follows:
● The bonnet must be closed ⇒ page 209.
● Switch the ignition on and off.
● Press the windscreen wiper lever downwards briefly ⇒ Fig. 64 4
.
Before driving, always lower the wiper arms. Using the windscreen wiper
lever, the windscreen wiper arms return to their initial position. 

122Lights and visibility
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

Care and cleaning
Windows
Clear vision is an essential safety factor.
The windscreen must not be cleaned with insect remover or wax, otherwise
the windscreen wipers will not function properly (juddering).
Traces of rubber, oil, grease or silicone can be removed with a window
cleaning solution or a silicone remover. Wax residue can only be removed
with a special cleaner. Your SEAT Official Service will be able to provide you
with more detailed information.
The windows should also be cleaned on the inside at regular intervals.
Use a separate cloth or chamois to dry the windows. Cloths used for waxing
and polishing contain residues that will cause smears on the glass.
WARNING
Do not use water-repellent coatings on the windscreen. In bad visibility
conditions (e.g. in the rain, dark or with a low sun), these coatings may
cause dazzle: risk of accident! Such coatings can also cause the wind-
screen wiper blades to make noise.
CAUTION
● Remove snow and ice from windows and exterior mirrors with a plastic
scraper only. To avoid scratches caused by dirt on the glass, the scraper
should only be pushed in one direction and not moved to and fro.
● The heating element for the rear window is located on the inner side of
the window. To avoid damaging them, do not apply stickers to the heating
elements.
● Never use warm or hot water to remove snow and ice from windows and
mirrors. This could cause the glass to crack! Rims
The wheels require regular attention to preserve their appearance. It is im-
portant to remove road salt and brake dust by washing the wheels at regu-
lar intervals, otherwise the finish will be impaired.
After washing, the wheels should only be cleaned with an "acid-free" clean-
ing agent for alloy wheels. This is available from SEAT Official Services and
specialist retailers. Never leave the cleaning agent on the rims for any lon-
ger than specified in the instructions before rinsing it off. If the wheel clean-
er fluid contains acid it can attack the surfaces of the wheel bolts.
Car polish or other abrasive agents should not be used for maintaining the
rims. If the protective coating is damaged, e.g. by stone impact, the dam-
aged area should be touched up immediately.
WARNING
Please note when cleaning the wheels that water, ice and road salt can
impair the effectiveness of the brakes; this can cause an accident.

Exhaust tail pipe
It is important to remove road salt and brake dust by washing the wheels at
regular intervals, otherwise the exhaust tail pipe material could be dam-
aged. To remove impurities, do not use rim, paint or chrome cleaners or oth-
er abrasive products. Clean the exhaust tail pipes with cleaning products
that are suitable for stainless steel.
SEAT Official Services carry stocks of cleaning products that have been tes-
ted and approved for use on your vehicle. 

210Checking and refilling levels
CAUTION
When changing or 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!
For the sake of the environment
Inspect the ground underneath your vehicle regularly so that any leaks are
detected at an early stage. If you find spots of oil or other fluids, have your
vehicle inspected at the workshop.
Note
On right-hand drive vehicles* some of the containers/reservoirs mentioned
below are located on the other side of the engine compartment. 
Opening the bonnet
The bonnet is released from inside the vehicle.

WARNING
Never open the bonnet if you see steam or drips of coolant being re-
leased from the engine compartment. Failure to comply could result in
burns. Wait until no steam or coolant can be seen before opening the
bonnet.

Closing the bonnet

220Checking and refilling levels
● Before starting any work on the battery, always observe the warnings lis-
ted under ⇒  page 218, Important safety warnings for handling a vehicle
battery.
● Do not forget to replace the battery coverings, where applicable. This
helps to protect against excess temperatures. This in turn extends the vehi-
cle service life.
For the sake of the environment
 Batteries contain toxic substances including sulphuric acid and lead. They
must be disposed of appropriately and must not be disposed of with ordi-
nary household waste. Make sure disconnected batteries cannot tip over.
Sulphuric acid could be spilt! 

partment: Windscreen
washer reservoir top The windscreen washer reservoir  contains the cleaning fluid for the wind-
screen, the rear window and the headlight washer system* ⇒ Fig. 112. Res-
ervoir capacity: ⇒ page 276.
To prevent the nozzles from becoming blocked with chalk deposits, fill res-
ervoir with water with a low calcium content (distilled water). Always add
washer fluid to the water (with anti-freeze additive in winter).
CAUTION
● Never put radiator anti-freeze or other additives into the windscreen
washer fluid.
● Never use washer fluid which contains paint thinners or solvents as it
can damage the paintwork. 
