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.
A lways us e a new fus e for re placeme nt. Never atte mp t to
repair or bridge a blown fuse.
A fuse chart is located in fuse box (1).
A fuse extractor is located in the auxiliary fuse box in
the trunk, see page 296.Fuse box in the passenger compartment

To gain access to fuse box, pull cover away from fuse
box (arrow) and remove rearward.
