Changing fuses
Procedure
Fuses are located throughout the vehicle, for ex-ample in the engine compartment, in the front cabin and in the luggage compartment.
To see whether a fuse has blown, check whether the metal strip has melted.
- Switch off the vehicle and all electrical equip-ment.
- Refer to the fuse layout tables to identify the fuse for the affected component.
- Remove the appropriate cover.
- If fitted, pull the coloured plastic frame out of the fuse carrier.
- Take the clip from inside the respective fuse box.
- Use the clip to pull out the fuse.
- Blown fuses should always be replaced with a fuse of the same ampere rating.
- Attach the plastic frame again if removed earli-er.
- Put the cover back on.
