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.
