Fuses and Relays
In general, a fuse can be assigned to various electrical components. Likewise, an electrical
component can be protected by several fuses.
Only replace fuses when the cause of the problem has been solved. If a newly inserted fuse blows after a short time, you must have the electrical system checked by a specialised workshop as soon as possible.
WARNING
The high voltages in the electrical system can give serious electrical shocks, causing burns and even death!
● Never touch the electrical wiring of the ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit without fuses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of the same amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To prevent damage to the vehicle's electric system, before replacing a fuse always turn off the ignition, the lights and all electrical elements and remove the key from the ignition.
● If you replace a fuse with higher-rating fuse, you could cause damage to another part of the electrical system.
● Protect the fuse boxes when open to prevent the entry of dust or humidity as they can damage the electrical system.
● Always carefully remove the fuse box covers and refit them correctly to avoid problems with your vehicle.
Note
● One component may have more than one fuse.
● Several components may run on a single fuse.
● In the vehicle, there are more fuses than those indicated in this chapter. These should only be changed by a specialised workshop.
● Positions not containing a fuse do not appear in the following tables.
● Some of the equipment listed in the tables below pertain only to certain versions of the model or are optional extras.
● Please note that the above lists, while correct at the time of printing, are subject to change.
