2. On the considered car models, the fuses are distributed over three mounting blocks. One mounting block is mounted in the instrument panel on the left. In this unit, control devices for electronic systems of the cabin and instrument panels are also installed. The second cabin mounting block is mounted in the left sidewall of the luggage compartment. In addition to fuses and relays, it contains control devices that control the functioning of the electronic systems in the rear of the car. The third mounting block is located on the left in the engine compartment next to the battery. The engine control module is installed in the same block (ECM). All blocks are equipped with removable covers.
3. To access the mounting block on the instrument panel, grasp the ledge on the service cover of the block (see resist. illustration) and pull it towards you with force, if necessary, use a plastic wedge. Remove the cover from the mounting slots and remove it.

4. To remove the cover of the mounting block in the luggage compartment on Sedan / Hatchback models, it is necessary to press 1, and on Station wagon / Signum models 2 latches (see resist. illustrations), open and remove the covers from the luggage compartment trim. On Wagon/Signum models, another service cover must be removed to access the fuses.

5. In the engine compartment, to remove the cover of the underhood fuse mounting block, you must first remove the cover of the battery protective cover (see chapter 5). Then press the latch (arrow A) (see resist. illustration) cover of the mounting block, pull the cover up (arrow B) and take it off.

6. Each individual fuse is used to protect a specific electrical circuit or multiple circuits. An identification card with a layout of fuses in the mounting block is usually glued to the cover of the latter, from its inside (see also Specifications).
7. The mounting blocks use fuses of a compact design, equipped with bayonet contacts, and, if necessary, easily removed from their sockets in the block. To remove the fuses, use a special clip (see illustration 3.7a), which is mounted on the back of the cover of the instrument panel fuse mounting block. In case of failure of any of the consumers of electricity, first of all, you should always check the condition of the corresponding fuse. Typically, the fuse case is made of transparent plastic, through which it is easy to determine the condition of the working jumper (see illustration 3.7b).
3.7a A special clip for extracting fuses is usually attached to the inside of the cover of the mounting block
3.7b The fact of the blown contact jumper of a failed fuse is easily detected by visual inspection of an element with a translucent body
8. When replacing a blown fuse, make sure that the prepared replacement element matches the type of the failed fuse. Each of the electrical circuits has different operating parameters and needs a different degree of protection, so replacing a fuse designed for a certain current strength that does not correspond to it in terms of parameters is fraught with the most serious consequences (until the fire). Fuse operating parameters (rated current) are usually marked on its plastic case, in addition, color identification is additionally used (see specs).
9. If the new fuse also fails immediately after installation, it makes no sense to replace it further - first, the cause of the overload in the circuit should be identified and eliminated. In most cases, this is a short circuit of the connecting wiring, caused by damage to its insulation. Spare fuses are placed in special sockets on the reverse side of the service cover of the instrument panel mounting block (see resist. illustration), as well as in free pads directly in the mounting blocks.

10. After completing work on the electrical equipment, replace the cover of the corresponding mounting block and check the fit and fixation of the cover.
