Operation
●
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

Main beam assist (Light Assist)
The main beam assist acts within the limits
of the system and depending on environmen-
tal and traffic conditions. Once switched on,
the system is activated as of a speed of
about 60 km/h (37 mph) and is deactivated
below about 30 km/h (18 mph) ››› .
When the sy s
t

em is activated and the camera
detects other vehicles that may be dazzled,
the main beam is automatically switched off.
Otherwise, the main beam is automatically
switched on. The main beam assist generally detects illu-
minated ar

eas and deactivates the main
beam when passing through a town, for ex-
ample.

 page 26
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 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.
● 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.

Operation
Motorway light* The motorway light is available on vehicles
equipped w

ull-LED lights.
The function is connected/disconnected via
the corresponding Easy Connect system
menu.
● Activation: when going abo
ve 110 km/h for
more than 30 seconds, the dipped beam rai-
ses slightly to increase the distance of visibil-
ity of the driver.
● Deactivation: when reduc in
g the speed of
the car below 100 km/h, the dipped beam re-
turns 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, lighting of

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 hea dlight

s dazzle and distract other driv-
ers. This could result in a serious accident.

be pul

led 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

Operation
Rain sensor modified behaviour
P o
s
sible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 144 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
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
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-
