2013 Seat Leon 5D engine

116Lights and visibility
When a car that is manufactured in a country that drives on the right travels
to a country that drives on the left (or vice versa), it is normally necessary to
cover part of the headlight bulbs with stickers or to change the adjustment
of the headlights to avoid dazzling other drivers.
In such cases, the regulations specify certain light values that must be com-
plied with for designated points of the light distribution. This is known as
“Tourist light”.
The light distribution that the halogen and full-LED headlights of the SEAT
Leon range have, allows the specific “tourist light” values to be met without
the need for stickers or changes in the settings.
Note
“Tourist light” is only allowed temporarily. If you are planning a long stay in
a country that drives on the other side, you should take the vehicle to an
Authorised Technical Service to change the headlights. 

● 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. 73 (arrow).
● To remove wax and coatings, we recommend a window cleaner contain-
ing alcohol. Checking and topping up the windscreen washer reservoir
with water
Fig. 74 In the engine
compartment: wind-
screen washer reservoir

Check the water level in the windscreen washer reservoir regularly and top
up as required.
● Open the bonnet 
⇒  page 251.
● The washer reservoir is marked with the symbol  on the lid
⇒ Fig. 74.
● Check there is enough water in the reservoir.
● To top up, mix water with a window cleaner recommended by SEAT
⇒ 
.
Please follow the instructions for use found on the packaging.
● In cold weather, a special antifreeze should also be added to prevent
the water from freezing ⇒ 
. 

Lights 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

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. 
