Some of the electrical items listed in the table are only fitted on certain
models or are optional extras.
Please note that the above list contains all data at the time of going to
press, so it is subject to modifications. Bulb change
General notes
Before changing any bulb, first turn off the failed component.
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.
Below, the light source used for all functions is broken down.
