Fuses and relays
The fuse box is placed under the instrument panel. The fuse
box shoul d always be kept clean. It contains 30 fuses. The
nominal current rating of the fuses is 5---20 A. If any of the
fuses blow, the fault must be traced and remedied. Fuses
must not be replaced with o nes of higher a rati ng, since this
may cause damage to the electrical equipment. There are
space for reserve fuses between the fuses.
Important! Fuses on E ---models, see section 34 (Autocontrol
III) or section 35 (Autocontrol IV)
