If a newly replaced fuse blows again after a short time, the electrical
system must be checked by a qualifi ed workshop as soon as possible.

If and when
244Bulb changeGeneral notesBefore changing any bulb, first turn off the failed component.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a
reduction in the bulb life and conden sation on the mirror surface, thus
reducing efficiency.
A bulb should only be replaced by one of the same type. The type is inscribed
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.

23)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.24)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 circum-
stances, there is no need to change the bulbs for the whole life of the vehicle.25)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 front lights, the fog
lights, the rear lights and the indicators may be temporarily misted. This has
no influence on the life expectancy 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 interest
of your own safety, but also in that of all other road users.
•
Due to the difficulty in accessing the lamps, any replacement work should
be done by a SEAT dealer. However, th e following is a description of how to
change the lamps except for the fog lights* and interior lamps.
