WARNING
The components of the exhaust system reach very high temperatures.
This c
ould cause a fire and considerable damage.
● Always park your vehicle so that no part of the exhaust system can
come in cont
act with flammable materials (such as dried grass or fuel). Note
● The vehicle battery will discharge and run down if the hazard warning
lights r
emain on for too much time (even with the ignition turned off).
● For some vehicles, the brake lights will blink when braking suddenly at
speeds
of approximately 80 km/h to warn vehicles behind. If braking con-

If and when
Fuses
Introduction Due to the constant update of vehicles, fuse assignments depending on
equipment and the u
se of
the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, 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 qualified dealership as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 275WARNING
The high voltages in the electrical system can give serious electrical
shock s, c
ausing 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 with-
out f u
ses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of
the same amperag
e (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar. CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
t urn off
the ignition, the lights and all electrical elements and remove the
keys 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 avoid the entry of dust or humidity.
Dirt and humidity
inside fuse boxes can cause damage to the electrical sys-
tem. Note
● One single consumer could have more than one fuse.
● Sev er
al consumers could run over one single fuse.
