Malfunctions
The following conditions may prevent the main beam headlight control from
turning off the headlights in time or from turning off altogether:
● In poorly lit towns with highly reflective signs.
● Other insufficiently lit road users (such as pedestrians or cyclists).
● On tight bends and steep slopes (bumps) and when oncoming vehicles
are partially obscured.
● When the drivers of other oncoming vehicles (such as a truck) can see
over a guard rail in the centre of the road.
● If the camera is damaged or the power supply is cut off.
● In fog, snow and heavy rain.
● With dust and sand turbulence.
● With loose gravel in the field of vision of the camera.
● When the field of vision of the camera is misted up, dirty or covered by
stickers, snow, ice...
WARNING
The convenience features of the main beam assist should not encourage
the taking of risks. The system is not a replacement for driver concentra-
tion.
● You are always in control of the main beam and adapting it to the
light, visibility and traffic conditions.
● It is possible that the main beam headlight control does not recog-
nise all driving situations and is limited under certain circumstances.
● When the field of vision of the camera is dirty, covered or damaged,
operation of the main beam control may be affected. This also applies
when changes are made to the vehicle lighting system, for example, if
additional headlights are installed.
CAUTION
To avoid affecting the operation of the system, take the following points in-
to consideration:
● Clean the field of vision of the camera regularly and make sure it is free
of snow and ice.
● Do not cover the field of vision of the camera.
● Check that the windscreen is not damaged in the area of the field of vi-
sion of the camera.
Note
Main beam and headlight flasher can be turned on and off manually at any
time with the turn signal and main beam lever ⇒ page 107. 
Adjusting the headlights
The light beam of the dipped beam lights is asymmetric: the side of the
road on which you are driving is lit more intensely. 

Lights 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. 
“Coming home” and “Leaving home” function (guidance
lights)*
The “Coming home” function should be switched on manually. However the
“Leaving home” function is automatically controlled by a photo sensor.
“Coming home”Necessary operations
To switch sys-
tem on:
– Switch off the ignition.
– Briefly flash the headlights for approximately one sec-
ond ⇒ page 107.
The “Coming home” lighting comes on when the driver
door is opened. The delay in switching off the headlights
is counted from when the last door or rear lid is closed.
The system
switches off:
– Automatically at the end of the delay period.
– Automatically, if 30 seconds after coming on, a vehicle
door or the rear lid remains open.
– If the light switch is turned to position .
– If the ignition is switched on.
“Leaving home”Necessary operationsTo switch sys-
tem on:– Unlock the vehicle when the light switch is in position
 and the photo sensor detects darkness.
The system
switches off:– Automatically, at the end of the delay period.
– When the vehicle is locked.
– When the light switch is turned to position .
– When the ignition is switched on.
Note
● In the Easy Connect system, the duration of the lighting can be adjus-
ted, and the function activated and deactivated ⇒ page 79 using the button 
and the function button Setup.
● When the “Coming home” function is activated, a tone can be heard
when the driver door is opened to warn that the light remains switched on. 

Headlight range control
The headlight range control ⇒ Fig. 62 is modified according to the value of
the headlight beam and the vehicle load status. This offers the driver opti-
mum visibility and the headlights do not dazzle oncoming drivers ⇒ 
.
The headlights can only be adjusted when the dipped beam is switched on.
To reset, turn switch ⇒ Fig. 62:

If the vehicle load does not correspond to those shown in the table, it is possible to select
intermediary positions.
Dynamic headlight range control
The control is not mounted in vehicles with dynamic headlight range con-
trol. The headlight range is automatically adjusted according to the vehicle
load status when the headlights are switched on.
Instrument panel lighting
In vehicles with the daytime driving light, the instrument panel lighting
switches on in dark conditions (for example, when passing through a tun-
nel). This reminds the driver to manually switch on the dipped beam, so
that the vehicle rear lights also switch on ⇒ page 109.
WARNING
Heavy objects in the vehicle may mean that the headlights dazzle and
distract other drivers. This could result in a serious accident.
● Adjust the light beam to the vehicle load status so that it does not
blind other drivers.

Introduction
Additional information and warnings:
● Changing wheels round
● Heating, ventilation, cooling
● Caring for and cleaning the vehicle exterior
WARNING
If the water from the windscreen washer does not contain enough anti-
freeze, it may freeze on the windscreen, reducing forward visibility.
● In winter, ensure the windscreen washer contains enough anti-freeze.
● In cold conditions, you should not use the wash/wipe system unless
you have warmed the windscreen with the ventilation system. The anti-
freeze could freeze on the windscreen and reduce visibility.
WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of acci-
dent and serious injury.
● Always replace damaged or worn blades or blades which do not clean
the windscreen correctly.
CAUTION
In icy conditions, always check that the wiper blades are not frozen to the
glass before using the wipers. In cold weather, it may help to leave the vehi-
cle parked with the wipers in service position ⇒ page 119. 

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. 
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
