in the fog lights and are switched on only at
speeds of less than 40 km/h (25 mph).
When reverse gear is engaged, the cornering
lights on both sides of the vehicle switch on,
in order to better illuminate the area for park-

Hazard warning lights Fig. 143
Dash panel: switch for hazard warn-
in g lights. Read the additional information carefully
› ›

 page 31
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 movin
g 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 aut
om

atic gearbox, move the gear
lever to P. 6. Use the warning triangle to draw the atten-
tion of other ro
ad users to your vehicle.
7. Always take the vehicle key with you when you le
ave the vehicle.
All turn signals flash simultaneously when
the hazard warning lights are switched on.
The two turn signal turn signal lamps  
and the turn signal lamp in the switch  will
flash at the same time. The simultaneous
hazard warning lights also work when the ig-
nition is switched off.
Emergency braking warning
If the vehicle brakes 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 the vehicles driving be-
hind. 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.
● Due to the high temperatures that the cata-
lytic con
verter can reach, never park in an
area where the catalytic converter could come into contact with highly inflammable materi-
al
s, f

or example dry grass or spilt petrol. This
could start a fire. Note
● The b atter

y 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 her
e is subject to the relevant statu-
tory requirements. Parking lights
 When the parking light is switched on, (right
or l
ef
t

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
sw
it
c

h 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 light* The motorway light is available on vehicles
equipped w
ith f
ull-LED lights.
The function is connected/disconnected via
the corresponding Easy Connect system
menu.
● Activation: when going abo
ve 110 km/h
(68 mph) for more than 30 seconds, the dip-
ped beam raises slightly to increase the driv-
er's visibility distance.
● Deactivation: when reduc in
g the speed of
the car below 100 km/h (62 mph), the dip-
ped beam returns to its normal position.
Driving abroad The light beam of the dipped beam lights is
a
symmetric: the s
ide 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
ful

l-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 ar e p

lanning 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

through a tunnel without the  function
active, the instrument panel lighting may

is to provide the driver with a visual indica-
tion that he or she should activate the dip-

If the ignition is switched off with the wind-

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
winds
creen wipers before starting your jour-
ney.
● Carefully lift the frozen windscreen wipers
from the gla
ss. SEAT recommends a de-icer
spray for this operation.
● Do not switch on the windscreen wipers if
the winds
creen is dry. Cleaning with the
windscreen wipers while dry can cause dam-
age. 148

In icy c ondition

● The w inds

function when the ignition is switched on and
the bonnet or rear lid, respectively, are
closed.
● The interval wipe speed varies according to
the vehic
le speed. The faster the vehicle is
moving, the more often the windscreen is
cleaned.
● The rear wiper is automatically switched on

Intervals between wipes depend

ly thaws the frozen jets, it
does not thaw the water in the washer hoses.
When the ignition is switched on the heated
windscreen washer jets automatically adjust

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 ar

e on the windscreen. The wiper will
stop moving if the obstacle blocks its path.
Remove the obstacle and switch the wiper
back on again. 149

Setting sensitivity level of rain sensor
– Set control to the right: highly sensi-

– Set control to the left: less sensitive.
When the ignition is switched off and then
back on, the rain sensor stays on and starts
operating again when the windscreen wipers
are in position 1 and the vehicle is travel-
lin g at
mor

e than 16 km/h (10 mph).
Rain sensor modified behaviour
Possible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 148 of
the rain sensor include:
● Damaged blades: a film of water on the
damag
ed 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 winds
creen wiper.
● Salt on roads: in winter, salt spread in the
roa
ds may cause an extra long wipe when the
windscreen is almost dry.
● Dirt: dry dust, wax, coating on glass (Lotus
effect) or trac
es of detergent (car wash) may
0 1
A reduce the effectiveness of the rain sensor or
m
ak
e it

react more slowly, later or not at all.
● Cracked windscreen: the impact of a stone
wil
l 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 sw it

ch on the wipers.
● If necessary, switch on the wipers manually
when water on the w
indscreen obstructs visi-
bility. Note
● Cle

an the sensitive surface of the rain sen-
sor regularly and check the blades for dam-
age ››› Fig. 148 (arrow).
