The electric windows are protected by circuit breakers. These reset automat-
ically after a few seconds when the overload (caused for example by frozen
windows) has been corrected.

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. 

Bulb change General notes
Before changing any bulb, first turn off the failed component.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a re-
duction in the bulb life and condensation on the mirror surface, thus reduc-
ing efficiency.
A bulb should only be replaced by one of the same type. The type is inscri-
bed on the bulb, either on the glass part or on the base.
It is highly recommended to keep a box of spare bulbs in the vehicle. At the
very least, the following spare bulbs, which are essential for road safety,
should be kept in the vehicle. Main headlights

On this type of headlight, the bulb changes must be made by the SEAT dealer, given that
complex elements must be removed from the vehicle and a reset must be made on the
automatic control system incorporated.
2) The Xenon bulbs discharge 2.5 times the light flux and have an average lifespan of 5 times
more than that of halogen bulbs, this means that, except due to unusual circumstances,
there is no need to change the bulbs for the whole life of the vehicle.
3) Electronically controlled single filament bulb for Stop/side bulbs. If the bulb blows it will
not work in either position or Stop.

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. 
