WARNING
Never “repair” damaged fuses and never replace them with fuses with a
higher rating. Failure to comply could result in fire. This could also cause
damage to other parts of the electrical system.
Note
● If a newly replaced fuse blows again after a short time, the electrical sys-
tem must be checked by a specialised workshop as soon as possible.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another location in the electrical system. ●
Always keep some spare fuses in the vehicle. These are available from
SEAT dealers.
● In addition to the fuses listed in the following tables, there are other
fuses which must be replaced by the Technical Service Workshop. 

If and when
Number plate light - C5W
Note
● Depending on weather conditions (cold or wet), the headlights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● 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.
● Due to the difficulty in accessing some of the bulbs, any replacement
work should be done by a SEAT dealer. However, the following is a descrip-
tion of how to change the lamps except for the fog lights* and interior
lamps. 
