Lights and visibility
WARNING
The side lights or daytime driving lights are not bright enough to illumi-
nate 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.

Lights and visibility: functions
Parking light remains on both sides
If when switching off the ignition, the light control remains in the posi-
tion  and the vehicle is closed from outside, both headlights, in addition
to the side lights and the rear lights will light up.
Daytime driving light
The daytime driving light consists of individual lights in the front head-
lamps.
When the daytime driving light is switched on, only the individual lights
come on ⇒ 
.
The daytime lights are switched on each time the ignition is turned on if the
light switch is in position .
Switching the daytime driving light on and off
To switch the daytime driving light on or off, it is necessary to fit or remove
the corresponding fuse. Ask for professional assistance for this.
WARNING
If the road is not well-lit and the vehicle is not clearly visible to other
drivers, there is a risk of accident.
● Never use the daytime driving light if the road is not well-lit as a re-
sult of the weather conditions and poor visibility. The daytime driving
lights are not bright enough to illuminate the road ahead and to ensure
that other road users are able to see you.
● The rear lights do not come on with the daytime driving light. A vehi-
cle which does not have the rear lights on may not be visible to other
drivers in the darkness, if it is raining or in conditions of poor visibility.
Note
The headlights, rear lights and turn signals may mist up temporarily on the
inside in cool or damp weather. This is normal and in no way effects the
useful life of the vehicle lighting system. 
Adjusting the headlights
In those countries where vehicles drive on the other side of the road to the
home country, the asymmetric dipped beam may dazzle drivers of oncom-
ing vehicles.
For this reason, stickers may need to be used to cover the headlights when
driving abroad. For further information, please refer to a specialised work-
shop. SEAT recommends visiting a Technical Service.
Note
The use of stickers to cover headlights is only permitted over a short period.
To modify the direction of the headlamps more permanently, please take
the vehicle to a specialised workshop. SEAT recommends visiting a Techni-
cal Service. 

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 180
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.
Note
Several consumers could run over one single fuse. 

Practical information
CAUTION
● Always carefully remove the fuse box covers and refit them correctly to
avoid problems with your vehicle.
● 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
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. 149 Image of a
blown fuse
Preparation
● Switch off the ignition, lights and all electrical equipment.
● Open the corresponding fuse box ⇒ page 262. Identifying a blown fuse
A fuse is blown if its metal strip is ruptured
⇒ Fig. 149.
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 for 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. 

Information for replacing bulbs
Checklist
To replace a bulb, carry out the following operations always in the order giv-
en ⇒ 
:
1. Park the vehicle a safe distance from traffic and on suitable ground.
2. Apply the handbrake firmly ⇒ page 134.
3. Turn the light switch to position 0 ⇒ page 84.
4. Move the gear lever into the neutral position ⇒ page 84.
5. Stop the engine and remove the key from the ignition ⇒ page 119.
6. Automatic gearbox: move the selector lever to position P
⇒ page 124.
7. Manual gearbox: Select a gear ⇒ page 124.
8. Allow the corresponding bulb to cool.
9. Visually inspect fuses to see if any are blown ⇒ page 261.
10. Replace the bulb according to the instructions ⇒ 
. Bulbs should
only be replaced by new identical models. Bulb information is dis-
played on the bulb socket or on the bulb itself.
11. In general, never touch the bulb glass directly. The heat of the bulb would cause the fingerprint to evaporate and condense on the reflec-
tor. This will impair the brightness of the headlight.
12. Check if the new bulb is working. If the bulb is not working, it maynot have been correctly fitted, it could be damaged or the connector
may not be correctly connected.
13. Every time a bulb for the headlights is replaced, visit a specialised workshop to check the headlights.
WARNING
Failure to follow the checklist prepared for your own safety could lead to
accidents and severe injuries.
● Always complete the operations given in the checklist and observe
the general rules of safety.
CAUTION
Always remove and fit headlights carefully to avoid damage to the paint-
work and other vehicle parts. 
