Bulb change

General notes
Before changing any bulb, first turn off the failed devices.
Do not touch the glass part of the bulb with your bare hands. The finger-
prints left on the glass will vaporise as a result of the heat generated by the
bulb, causing a reduction in bulb life and condensation on the mirror sur-
face, thus reducing effectiveness.
A bulb must only be replaced by one of the same type. The type is indicated
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
Dipped beam - H7
Main beam - H1
Position - W5W
Turn signal - PY21W
1)
For this type of headlight, the bulb must replaced by the Technical Service, given that com-
plex elements must be removed from the vehicle and a reset must be made on the auto-
matic 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.
