Lights and visibility
● When the drivers of other oncoming vehi-
cles (such as a truck) can see over a guard
rail in the centre of the road.
● If the camera is damaged or the power sup-
ply 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, etc. WARNING
The convenience features of the main beam
assist should not encourage the taking of
risks. The system is not a replacement for
driver concentration.
● You are always in control of the main beam
and adapting it to the light, visibility and traf-
fic conditions.
● It is possible that the main beam headlight
control does not recognise all driving situa-
tions and is limited under certain circumstan-
ces.
● 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 vehi- cle lighting system, for example, if additional
headlights are installed.
CAUTION
To avoid affecting the operation of the sys-
tem, take the following points into considera-
tion:
● Clean the field of vision of the camera regu-
larly and make sure it is free of snow and ice.
● Do not cover the field of vision of the cam-
era.
● Check that the windscreen is not damaged
in the area of the field of vision 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

Hazard warning lights Fig. 99
Dash panel: switch for hazard warn-
ing lights. Read the additional information carefully
›››  page 15
The hazard warning lights are used to draw
the attention of other road users to your vehi-
cle in emergencies.
If your vehicle breaks down:
1. Park your vehicle at a safe distance from moving traffic.
2. Press the button to switch on the hazard warning lights ››› .
3. Switch the ignition off.
4. Apply the handbrake.
5. For a manual gearbox, engage 1st gear; for an automatic gearbox, move the gear
lever to P
. 6. Use the warning triangle to draw the atten-
tion of other road users to your vehicle.
7. Always take the vehicle key with you when you leave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps  
and the t

urn signal lamp in the switch  will
flash at the same time. The hazard warning
lights also work when the ignition is switch-
ed off.
Emergency braking warning
If the vehicle is braked suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times
per second to warn vehicles driving behind. If
you continue braking, the hazard warning
lights will come on automatically when the
vehicle comes to a standstill. They switch off
automatically when the vehicle starts to
move again. WARNING
● The risk of an accident increases if your ve-
hicle breaks down. Always use the hazard
warning lights and a warning triangle to draw
the attention of other road users to your sta-
tionary vehicle.
● Never park where the catalytic converter
could come into contact with inflammable materials under the vehicle, for example dry
grass or spilt petrol. This could start a fire!
Note
● The battery will run down if the hazard
warning lights are left on for a long time,
even if the ignition is switched off.
● The use of the hazard warning lights de-
scribed here is subject to the relevant statu-
tory requirements. Parking light
When the parking light is switched on, (right
or left turn signal), the front side light and
the rear light on the corresponding side of
the vehicle stay lit. The parking lights can on-
ly be activated with the ignition switched off
and the turn signal and main beam lever in
the central position, before being triggered.
Parking light on both sides With the ignition switched off and the light
switch in position 
, when locking the vehi-
cle from the outside, the parking lights on
both sides of the vehicle light up. In doing
so, only the side lights of both headlights
light up, and additionally the tail lights will
do so partially.

Operation
Motorway lights* The motorway light is available on vehicles
equipped with full-LED lights.
The function is connected/disconnected via
the corresponding Easy Connect system
menu.
●
Activation: when going above 110 km/h for
mor e th
an 30 seconds, the dipped beam rai-
ses slightly to increase the distance of visibil-
ity of the driver.
● Deactivation: when reducing the speed of
the c ar belo

w 100 km/h, the dipped beam re-
turns to its normal position.
Driving abroad The light beam of the dipped beam lights is
asymmetric: the side of the road on which
you are driving is lit more intensely.
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 nor-
mally necessary to cover part of the headlight
bulbs with stickers or to change the adjust-
ment of the headlights to avoid dazzling oth-
er drivers.
In such cases, the regulations specify certain
light values that must be complied 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. Headlight range control, lighting of

Dynamic headlight range control
The control is not mounted in vehicles with
dynamic headlight range control. The head-
light range is automatically adjusted accord-
ing to the vehicle load status when they are
switched on.
Instrument panel lighting
With the ignition on and without light activa-
tion, the instrument panel lighting remains
activated in daytime light conditions. The
lighting is reduced as the exterior light di-
minishes. In some cases, e.g. when driving
through a tunnel without the  function
active, the instrument panel lighting may
even switch off. The objective of this function
is to provide the driver with a visual indica-
tion that he or she should activate the dip-
ped beam. WARNING
Heavy objects in the vehicle may mean that
the headlights dazzle and distract other driv-
ers. This could result in a serious accident.
● Adjust the light beam to the vehicle load
status so that it does not blind other drivers. Interior and reading lights

›››  page 16 CAUTION
If the ignition is switched off with the wind-
screen wipers active, they complete their wipe before returning to the rest position.
Ice, snow and other obstacles on the wind-
screen may damage the wiper and the wind-
screen wiper motor.
● If necessary, remove snow and ice from the
windscreen wipers before starting your jour-
ney.
● Carefully lift the frozen windscreen wipers
from the glass. SEAT recommends a de-icer
spray for this operation.
● Do not switch on the windscreen wipers if
the windscreen is dry. Cleaning with the
windscreen wipers while dry can cause dam-
age.
● In icy conditions, always check that the
wiper blades are not frozen to the glass be-
fore using the wipers. In cold weather, it may
help to leave the vehicle parked with the wip-
ers in service position ››› page 230. Note
● The windscreen and window wipers only
function when the ignition is switched on and
the bonnet or rear lid, respectively, 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. 102

The air conditioner comes on for
approximately 30 seconds in air
recirculation mode to prevent the
smell of the windscreen washer

cle.
For the interval wipe
Intervals between wipes depend
on the vehicle's speed. The high-
er 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 automati-
cally adjust the heat depending on the ambi-
ent temperature, when the ignition is switch-
ed 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 windscreen 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 insects) should be
cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work cor-
rectly 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 obstacle and switch the wiper
back on again. Rain sensor*

Operation
Rain sensor modified behaviour
Possible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 104 of
the r ain sen
sor include:
● 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 continuous wipe.
● Insects: insects on the sensor may trigger
the windscreen wiper.
● 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 cycle with the rain
sensor on. Next the rain sensor detects the
reduction in the sensitive surface area and
adapts accordingly. The behaviour of the sen-
sor 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 windscreen obstructs visi-
bility. Note
● Clean the sensitive surface of the rain sen-
sor regularly and check the blades for dam-
age ››› Fig. 104 (arrow).
● To r
emove wax and coatings, we recom-
mend a window cleaner containing alcohol. Rear vision mirror

ded in automatically. When the vehicle is
opened with the remote control, the exterior
mirrors are deployed automatically. WARNING
Convex or wide-angle* exterior mirrors give a
larger field of vision. However, they make ob-
jects look smaller and further away than they
really are. If you use these mirrors to esti-
mate the distance to vehicles behind you
when changing lane, you could misjudge the
distance. Risk of accident! CAUTION
● If one of the mirror housings is knocked out
of position (e.g. when parking), 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.
