Caution: Before working with the battery, read the precautions in the section again Safety first at the beginning of this guide.
- Make sure the battery tray is in good condition and securely fastened. Corrosion on the tray, clamps and the battery itself can be removed with a solution of soda and water. After that, rinse the treated surfaces thoroughly with water. Cover metal parts damaged by corrosion with a zinc-based primer and paint.
- Periodically (at least once every three months) check the battery charge level as described in Chapter 5A.
- If your battery is dead and you need to jump start the engine, see the "Road Repair" section.
Battery corrosion can be minimized by lubricating the terminals and posts with Vaseline after connecting the wires.
1. The battery is located on the right side of the rear engine compartment. Regularly check the appearance of the battery, paying attention to the absence of cracks in its housing or cover.
2. Check that the clamps are securely fastened to the terminals, ensuring reliable electrical contact. A clamp that is tightly tightened cannot be turned on the terminal. Also check the battery cables for damage.
3. If traces of corrosion are found on the terminals or clamps (white loose deposits), disconnect the wires from the terminals, clean them with a wire brush and reinstall them. Special terminal cleaning devices can be found in stores with related products.
4. Note that the positive battery terminal can be disconnected for cleaning or replacement by unscrewing the nut located under the plastic cover.
