The essentials
Jump leads must comply with standard DIN
72553 (see c ab
l
e manufacturer's instruc-
tions). The wire cross section must be at least
25 mm 2
for petrol engines and at least
35 mm 2
for diesel engines. Note
● The v ehic

les must not touch each other,
otherwise electricity could flow as soon as
the positive terminals are connected.
● The discharged battery must be properly

situations.
Audible warnings to advise the driver that
the lights have not been switched off
If the key is not in the ignition and the driver
door is open, an audible warning signal is
heard in the following cases: this is a remind-
er to turn off the lights.
● When the parking light is on ››

● When the light switch is in position  or
. WARNING
The side lights or daytime running lights are
not bright enough t

o illuminate the road
ahead and to ensure that other road users are
able to see you.
● Always use your dipped beam head lights if
it is
raining or if visibility is poor. WARNING
If the headlights are set too high and not
used c orr

ectly, there is a risk of dazzling or
distracting other road users. This could result
in a serious accident.
● Always make sure that the headlights are
correctly
adjusted. Note
The legal requirements regarding the use of
vehic l

e lights in each country must be ob-
served. Daytime running lights
The daytime running lights consist of individ-
ual
lights, int
e

grated in the front headlights.
With the daylight driving lights on, only these
lights switch on ››› .
The d a
ytime ru

nning lights switch on every
time the ignition is switched on, if the switch
is in positions  or , according to the level
of exterior lighting.
When the light switch is in position , a
light sensor automatically switches dipped
beam on and off (including the control and

Lights and visibility
WARNING
● Never driv e w
ith daytime lights if the road
is not well lit due to weather or lighting con-
ditions. Daytime lights do not provide
enough light to illuminate the road properly
or be seen by other road users.
● The rear lights do not come on with the
daytime driv
ing light. A vehicle which does
not have the rear lights on may not be visible
to other drivers in the darkness, in the case
of heavy rain or in conditions of poor visibili-
ty. Turn signal and main beam lever

 page 33. In vehicles that do not have the correspond-
ing menu, this

function can be deactivated in
a specialised workshop. WARNING
Improper or lack of use of the turn signals, or
for g

etting to deactivate them can confuse
other road users. This could result in a seri-
ous accident.
● Always give warning when you are going to
chan
ge lane, overtake or when turning, acti-
vating the turn signal in good time.
● As soon as you have finished changing
lane, ov
ertaking or turning, switch the turn
signal off. WARNING
Incorrect use of the headlights may cause ac-
cident s

and serious injury, as the main beam
may distract or dazzle other drivers. Note
● If the c on

venience turn signals are operat-
ing (three flashes) and the other convenience
turn signals are switched on, the active part
stops flashing and only flashes once in the
new part selected.
● The turn signal only works when the igni-
tion is sw
itched on. The hazard warning
lights also work when the ignition is switch-
ed off. ●
If a tr ai

ler turn signal malfunctions, the
control lamp will stop flashing (trailer turn
signals) and the vehicle turn signal will flash
at double speed.
● The main beam headligh
ts can only be
switched on if the dipped beam headlights
are already on.
● In cold or damp weather conditions, the
headlight
s, tail lights and turn signals may
mist up inside temporarily. This is normal and
in no way effects the useful life of the vehicle
lighting system. Automatic dipped beam control

The f
o
l

lowing conditions may prevent the
main beam headlight control from turning off
the headlights in time or from turning off al-
together:
● In poorly lit towns with highly reflective
signs.
● Other in

sufficiently lit road users (such as
pedestri
ans or cyclists). ●
On tight bends
and steep slopes (bumps)
and when oncoming vehicles are partially ob-
scured.
● When the drivers of other oncoming vehi-
cle
s (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 i
s 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 fiel

d of vision of the camera is
mist
ed up, dirty or covered by stickers, snow,
ice, etc. WARNING
The convenience features of the main beam
as s

ist 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 adaptin
g it to the light, visibility and traf-
fic conditions.
● It is possible that the main beam headlight
contro
l does not recognise all driving situa-
tions and is limited under certain circumstan-
ces.
● When the field of vision of the camera is
dirty, c
overed or damaged, operation of the
main beam control may be affected. This also
applies when changes are made to the 142

Lights and visibility
vehicle lighting system, for example, if addi-
tiona
l
headlights are installed. CAUTION
To avoid affecting the operation of the sys-
t em, t ak

e the following points into considera-
tion:
● Clean the field of vision of the camera regu-
larly and m
ake 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

are activated automati-
cally. The cornering lights may be integrated
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-
ing.

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
