329 Fuses
Te ch n ica l

cluster displayPractical hintsCar care Index Fuses
Most of your vehicle’s electrical components are fused
with safety fuses. With the exception of the brake lights,
all individual lighting system components are
electronically fused. Before replacing a blown safety
fuse, determine the cause of the short circuit. Always
observe amperage and color of fuse.
The circuit for components is protected by a cycled
circuit breaker interrupted if too much current is being
drawn. The circuit closes automatically after a short
time; the circuit is broken again if the malfunction
reoccurs.
Always use a new fuse for replacement. Never attempt to
repair or bridge a blown fuse.
A fuse chart, spare fuses and a fuse extractor are located
in the vehicle tool kit in the luggage bowl under the
trunk f loor. See page 338 for notes on the vehicle tool
kit.Fuse boxes in the engine compartment
