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”

Fuses and bulbs
Fuses and bulbs Fuses
Introduction
Due to the constant update of vehicles, fuse assignments depending on
equipment and the use of the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, an electrical component can be protected by several fuses.
Only replace fuses when the cause of the problem has been solved. If a
newly inserted fuse blows after a short time, you must have the electrical
system checked by a specialised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 251
WARNING
The high voltages in the electrical system can give serious electrical
shocks, causing burns and even death!
● Never touch the electrical wiring of the ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out fuses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of
the same amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
turn off the ignition, the lights and all electrical elements and remove the
keys from the ignition.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another part of the electrical system.
● Protect the fuse boxes when open to avoid the entry of dust or humidity.
Dirt and humidity inside fuse boxes can cause damage to the electrical sys-
tem.
Note
● One single consumer could have more than one fuse.
● Several consumers could run over one single fuse. 

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* 

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. 
