WARNING
If you manipulate, bridge or replace a faulty
fuse with a fuse of a higher amperage, the
electric cables could be overloaded. This may result in a fire. There is a risk of an accident
and injury.
Always replace faulty fuses with specified new fuses of the correct amperage.
! Only use fuses marked with an "S" for the
fuse box in the engine compartment and
under the rear bench seat. Components or
systems could otherwise be damaged.
The fuses in your vehicle disconnect faulty cir-
cuits. If a fuse blows, all the components on the
circuit and their functions will fail.
Blown fuses must be replaced with fuses of the same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed
in the fuse allocation chart.
The fuse allocation chart is located in the fuse
box under the rear bench seat (Y page 347).
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified special-
ist workshop, e.g. a Mercedes-Benz Service
Centre. Before replacing a fuse
