– Press together the interlocks of the fuse
cover simultaneously in direction of arrow
page 197, fig. 163
and push out the cover in direction of arrow .
– Release the fixtures in the openings using a flat screwdriver and fold the cover
upwards in direction of arrow .
– Find out which fuse belongs to th
e component which is not operating.
– Defect fuses can be detected by their melted metal strips. Replace the defect fuse
by a new fuse of the
same
ampere number.
Caution
Never attempt to “repair” fuses and also do
not replace them with a fuse of a higher
amperage - risk of fire! This
may also cause damage at an
other part of the electrical
system.
Have the electrical system checked as quickl
y as possible by a specialist garage if a
newly inserted fuse blows again after a short time.
Note
We recommend that you have these fuse
s replaced by a specialist garage.
