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, while correct at the time of printing, is subject
to alterations.Bulb changeGeneral notesBefore changing any bulb, first turn off the equipment concerned.
Do not touch the bulb glass. Fingerprints vaporise in the heat, causing a
reduction in the bulb life and condensation 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 bulbs that most affect road safety should have spares in the
vehicle.
