Main fuses
1. Fuses are located on the central mounting block located at the rear of the engine compartment on the right side (see fig. 3.1). On some models, there may be several additional fuses located on the auxiliary fuse box, which is located behind the main unit.

2. To access the fuses, loosen the front latch of the fuse cover, then unlatch and remove the cover (see fig. 3.2).

3. A list of the circuits that the fuse protects is given on a label attached to the inside of the fuse box cover.
4. To remove the fuse, first turn off the required circuit (or ignition), then remove the fuse from the block terminals. The wire inside the fuse should be visible. If the fuse is blown, it must be destroyed or melted (see fig. 3.4).

5. Always replace the fuse with an identical current rating, never use a fuse with a different current rating and do not "bugs". Never replace a fuse more than once. before you find out and eliminate the cause of the burnout. The current for which the fuse is designed is knocked out on top of the case. Remember that fuses are also color coded.
6. If a new fuse blows immediately, find the cause before installing again. The most likely cause is a short to ground due to poor insulation. Where a fuse is protecting more than one circuit, try to determine the cause of the fault by turning on the (if it is possible) each circuit until the fuse blows again. Always keep spare fuses with different ratings on your vehicle. Spare fuses must be clipped onto the base of the fuse box.
Relay
7. The relays are located on the central mounting block behind the fuses and also on an additional holder located immediately in front of the main block (see fig. 3.7).

8. If the faulty circuit or part of the system is controlled by the relay, and it is suspected that the cause of the fault is the relay, turn on the system. When a good relay is activated, a clicking sound should be heard. In this case, parts or secondary wiring in the loop may be the cause of the system failure. If the relay is not activated, then either the relay is not supplied with voltage, or the relay itself is faulty. The test consists of replacing the faulty relay with a known good relay. However, be careful, because with external similarity, the relays may differ functionally.
9. To remove a relay, first check that the corresponding circuit is turned off. The relay can simply be pulled out of the block and inserted a new one by pressing on the case.
