Attention! If the stereo system installed in the car is equipped with a security code, before disconnecting the battery, make sure that you have the correct combination to activate the audio system!
The cars of this model are equipped with an SRS system, the main component of which is airbags, which turns off after a fairly short time after disconnecting the wires from the battery. If the SRS warning light comes on after connecting the battery and stays on, the vehicle must be driven to a workshop to activate the SRS.
1. Regularly inspect the battery wires along their entire length for signs of mechanical damage, cracks and insulation burnouts, as well as corrosion. Do not forget that a violation of the quality of the electrical connection of the contact terminals can lead to difficulties in starting the engine, as well as a decrease in the efficiency of its return.
2. Check the wire terminals for cracks, signs of copper strands falling out, and signs of corrosion. The presence of white powdery deposits accumulated under the insulation layer near the terminal lugs indicates the development of corrosion and the need to replace the wire. Check battery terminals and wire end clamps for signs of deformation, loose bolts, and corrosion.
3. The negative lead is always disconnected from the battery first and connected last. Remember to disconnect the negative wire even if only the positive one is to be replaced.

4. Disconnect the old wires from the battery (first negative), then "take a walk" for each of them to the opposite end and disconnect from the starter traction relay (positive) and ground terminals (negative). Try to remember the routes for laying both wires in order to follow them when installing new ones.
5. Make sure that the replacement wires are the same size as those removed from the vehicle. Take the wire to be replaced with you to the store as a sample. An extremely important factor is that the design of the wire clamps matches the shape of the connection terminals on the vehicle.
Note. The wires are easily distinguished from each other by the color of the insulation, always black on the negative, and red on the positive. In addition, the positive wire usually has a larger cross section.
6. Using a wire brush, clean the threads on the connecting terminals of the traction relay and grounding. After all traces of corrosion have been removed, lightly lubricate the threads with acid-free Vaseline to prevent further corrosion.
7. Connect a wire to the plug of the traction relay/weight, firmly tighten a fixing nut/bolt.
8. Before connecting a new wire to the battery terminal, make sure that it reaches freely without excessive tension. Thoroughly clean the battery terminals, then lightly grease them with acid-free Vaseline.
9. Always connect the positive lead to the battery first, then the negative lead.
