2012 Seat Leon 5D window

102Opening and closing
One-touch opening
–Push down the window button briefly up to the second position.
The window opens fully.
Restoring one-touch opening and closing
– The automatic open and close function will not work if the bat-
tery has been temporarily disconnected. The function can be re-
stored as follows:
– Close the window as far as it will go by lifting and holding the
electric window switch.
– Release the switch and then lift it again for one second. This
will re-enable the automatic function.
If you push (or pull) a button to the first stage, the window will open (or
close) until you release the button. If you push or lift the button briefly to
the second stage, the window will open (one-touch opening) or close (one-
touch closing) automatically. If you operate the button while the window is
opening or closing, it stops at this position. 
Roll-back function
The roll-back function reduces the risk of injury when the
electric windows close.
● If a window is obstructed when closing automatically, the window stops
at this point and lowers immediately ⇒ 
.
● Next, check why the window does not close before attempting it again.
● If you try within the following 10 seconds and the window closes again
with difficulty or there is an obstruction, the automatic closing will stop
working for 10 seconds. ●
If the window is still obstructed, the window will stop at this point.
● If there is no obvious reason why the window cannot be closed, try to
close it again by pulling the tab within ten seconds. The window closes with
maximum force. The roll-back function is now deactivated.
If more than 10 seconds pass, the window will open fully when you operate
one of the buttons. One-touch closing is reactivated.
WARNING
● Incorrect use of the electric windows can result in injury.
● Always take the ignition key with you when leaving the vehicle, even
if you only intend to be gone for a short time. Please ensure that children
are never left alone inside the vehicle.
● The electric windows will work until the ignition has been switched
off and one of the front doors has been opened.
● Closing the windows without observing and ensuring it is clear could
cause serious injury to you and third parties. Make sure that no one is in
the path of a window.
● Never allow people to remain in the vehicle when you close the vehi-
cle from the outside. The windows cannot be opened even in an emergen-
cy.
● The roll-back function does not prevent fingers or other parts of the
body getting pinched against the window frame. Risk of accident.

start.
6Interval wipe for rear window. The rear wiper will wipe the win-
dow approximately every six seconds.
7The windscreen washer function is activated by pressing the
lever, and the rear wiper starts simultaneously.
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. 

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

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

Introduction
Viewing Climatronic information
On the screen of Climatronic control unit and on the screen of the factory-
fitted Easy Connect system, the theoretical values of the temperature zones
are shown.
The unit of temperature measurement can be changed in the Easy Connect
system.
Dust and pollen filter
The dust and pollen filter with its activated charcoal cartridge serves as a
barrier against impurities in the air taken into the vehicle interior.
The dust and pollen filter must be changed regularly so that air conditioner
performance is not adversely affected.
If the filter loses efficiency prematurely due to use in areas with very high
levels of air pollution, the filter must be changed more frequently than sta-
ted in the Service Schedule.
Additional information and warnings:
● Easy Connect system
● Seat functions
● Windscreen wipers and washers
● Caring for and cleaning the vehicle exterior
WARNING
Reduced visibility through the windows increases the risk of serious acci-
dents.
● Always ensure that all windows are free of ice and snow, and that
they are not fogged, so as to maintain good visibility of everything out-
side.
● The maximum heat output required to defrost windows as quickly as
possible is only available when the engine has reached its normal run-
ning temperature. Only drive when you have good visibility.
● Always ensure that you use the heating system, fresh air system, air
conditioner and the heated rear window to maintain good visibility to the
outside.
● Never leave the air recirculation on for a long period of time. If the
cooling system is switched off and air recirculation mode switched on,
the windows can mist over very quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is not required.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never leave the fresh air fan turned off or use the air recirculation for
long periods of time; the air in the vehicle interior will not be refreshed. 

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
● When the cooling system is turned off, air coming from the outside will
not be dried. To prevent fogging of the windows, SEAT recommends leaving
the cooling system (compressor) turned on. To do this, press the button 
.
The button lamp should light up.
● The maximum heat output required to defrost windows as quickly as
possible is only available when the engine has reached its normal running
temperature.
● Keep the air intake slots in front of the windscreen free of snow, ice and
leaves to ensure heating and cooling are not impaired, and to prevent the
windows from misting over. Air conditioner controls
