Lights Introduction
The legal requirements regarding the use of vehicle lights in each country
must be observed.
The driver is personally responsible for the correct use and adjustment of
the lights in all situations.
Additional information and warnings:
● Information system ⇒ page 73
● Changing bulbs ⇒ page 293
WARNING
If the headlights are regulated too high and the main beam is not used
correctly, 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.
● Never use the main beam or headlight flasher when it can dazzle oth-
er drivers.

116Lights 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 “function”
This function may be connected/disconnected through the radio menu. The
“Coming Home” and/or “Leaving Home” delay functions may also be set
(default: 30 sec.).

gen headlightsIn the “Coming Home” function, the daytime running
lights (DRL), the rear side lights and the licence plate
lights are turned on.

Fuses and bulbs
Note
In the vehicle, there are more fuses than those indicated in this chapter.
These should only be changed by a specialised workshop. 
Replacing a blown fuse
Fig. 179 Image of a
blown fuse
Preparation
● Switch off the ignition, lights and all electrical equipment.
● Open the corresponding fuse box ⇒ page 292.
Identifying a blown fuse
A fuse is blown if its metal strip is ruptured ⇒ Fig. 179.
Point a lamp at the fuse. This will make it easier to see if the fuse is blown. To replace a fuse
●
Remove the fuse.
● Replace the blown fuse by one with an identical amperage rating (same
colour and markings) and identical size ⇒ 
.
● Replace the cover again or close the fuse box lid.
CAUTION
If you replace a fuse with higher-rating fuse, you could cause damage to an-
other part of the electrical system. 
Bulbs
Changing a bulb
Changing bulbs requires a certain degree of practical skill. If you choose to change engine compartment lamps yourself, remember
that it is a dangerous area ⇒ 
in Working on components in the engine
compartment on page 251.
Always use identical bulbs with the same designation. The name can be
found on the base of the bulb holder.
Depending on how equipped the vehicle is, there are different sets of head-
lights and tail lights:
● Halogen headlights
● Full-LED main headlights*
● Rear bulb light
● LED rear light* 

294Fuses and bulbs
Full-LED headlight system*
Full-LED headlights handle all light functions (daylight, side light, turn sig-
nal, dipped beam and route light) with light emitting diodes (LEDs) as a
light source.
Full-LED headlights are designed to last the lifetime of the car and light
bulbs cannot be replaced. In case of headlight failure, go to an authorised
workshop to have it replaced.

WARNING
● Take particular care when working on components in the engine com-
partment if the engine is warm. Risk of burns.
● Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
● When changing bulbs, please take care not to injure yourself on sharp
edges, in particular on the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. Other-
wise, a short circuit could occur.
● Switch off the lights or parking lights before you change a bulb.
● Take good care to avoid damaging any components.
For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also that of all other road users.
● Before changing a bulb, make sure you have the correct new bulb.
● Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will va-
porise as a result of the heat generated by the bulb, they will be deposited
on the reflector and will impair its surface. 
