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. 

264Practical information
Changing bulbs
Introduction
Changing bulbs requires a certain amount of manual skill. If you are unsure,
SEAT recommends that you consult a Technical Service or request assis-
tance from a specialist. In general a specialist is needed if, in addition to
the bulbs, other vehicle components require removal.
You should store spare light bulbs in the vehicle for safety-relevant lights.
Spare bulbs may be obtained from the Official dealers and workshops. In
some countries, it is a legal requirement to carry spare bulbs in the vehicle.
Driving with faults and blown bulbs on the vehicle exterior lighting is
against the law.
Additional bulb specifications
The specifications of some headlamp bulbs and bulbs for the tail lamps fit-
ted at the factory may be different to those of conventional bulbs. Bulb in-
formation is displayed on the bulb socket or on the bulb itself.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Lights and visibility ⇒ page 84
● Working in the engine compartment ⇒ page 180
● Vehicle tools ⇒ page 246
● Fuses ⇒ page 261
WARNING
If the road is not well-lit and the vehicle is not clearly visible to other
drivers, there is a risk of accident.
WARNING
Failure to replace bulbs correctly may cause serious accidents.
● Before carrying out any work in the engine compartment please read
and observe the warnings ⇒ page 180. In any vehicle, the engine com-
partment is a hazardous area and could cause severe injury.
● The bulbs H4, HB4 and H7 are pressurised and might explode on
changing them.
● Only replace the bulbs concerned when they have cooled.
● Never replace bulbs alone if you are not familiar with the operations
necessary. If you are not sure about procedures then visit a Specialised
workshop to carry out the necessary work.
● Never touch the bulb glass directly. Fingerprints will be evaporated by
the heat of the operating bulb thus “fogging” up the reflector.
● The headlamp frameworks in the engine compartment and the tail
lamps contain sharp elements. Always protect your hands when chang-
ing bulbs.
CAUTION
After changing a bulb, if the rubber covers are not replaced correctly on the
headlamp framework, the electrical installation may be damaged, especial-
ly if water is allowed to enter. 

Practical information
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. 
