Locate the interior power panel under the dashboard on the driver side and the engine compartment unit near the battery, then compare each slot number with the printed legend on the cover. Match amperage values such as 10A, 15A, or 30A before pulling any insert to avoid damage to connected systems.
Each slot controls a specific circuit, including lighting, audio system, power windows, ignition, and cooling fans. Use the label chart on the крышка to identify which component corresponds to a given position. For example, a 15A insert often protects the cigarette lighter or accessory outlet, while higher ratings handle blower motors or ABS.
Check suspected elements by removing them with plastic tweezers and inspecting the metal strip inside. A broken or burned link indicates failure. Replace only with the same rating, and never install a higher value, as this increases the risk of wiring damage. Keep spare inserts in the glove compartment for quick replacement during roadside issues.

Open the driver side lower panel and check the cabin power block first, as it contains circuits for interior electronics such as radio, dashboard lights, and power locks. The cover typically includes a printed layout showing slot numbers and assigned functions.
The engine compartment unit sits near the battery and houses high load protection elements. These include connections for cooling fans, ignition system, and charging components. Look for clearly marked ratings like 40A or 50A used for larger systems.
Each slot number corresponds to a specific electrical path. For example, one position may control windshield wipers, while another handles brake lights. Always verify the label before removing any insert to avoid disconnecting the wrong system.
Interior circuits usually range from 7.5A to 20A. Lower ratings protect sensitive electronics, while mid range values are assigned to accessories such as power outlets and seat controls.
Under hood protection elements often include relay switches alongside inserts. Relays control functions like horn operation or headlight activation and can be identified by their larger square shape compared to standard blade components.
If a circuit stops working, compare the suspected slot with the printed layout and inspect the metal strip inside. A visible break confirms failure and requires replacement with an identical rating.
Keep a small puller tool in the vehicle and store spare inserts of common ratings like 10A and 15A. This allows quick restoration of lighting or accessory functions without tools or workshop access.

Check under the dashboard on the driver side, just above the footwell near the steering column, where the cabin electrical panel is mounted behind a removable plastic cover. Pull the lid straight out to access the rows of blade inserts and the printed slot map on the inner side.
Open the hood and look to the right side of the engine compartment next to the battery, where the main power distribution unit is secured in a black rectangular housing with locking tabs. Press the clips on both sides to lift the cover and reveal high current protection elements along with relay modules arranged in a grid.
A smaller auxiliary panel may also be positioned near the driver side kick panel or behind a trim piece, depending on trim level, so inspect side panels carefully if certain systems are not listed in the primary cabin layout.
