Checking the Battery TEST INDICATOR WINDOW Check the terminals for corrosion (a white or yellowish powder). To remove it, cover the terminals with a solution of baking soda and water. It will bubble up and turn brown. When this stops, wash it off with plain water. Dry off the battery with a cloth or paper towel. Coat the terminals with grease to help prevent future corrosion. If additional battery maintenance is needed, see your Honda dealer or a qualified technician. WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds. Wash your hands after handling. Check the condition of the battery monthly by looking at the test indicator window. The label on the battery explains the test indicator's colors. The battery gives off explosive hydrogen gas during normal operation. A spark or flame can cause the battery to explode with enough force to kill or seriously hurt you. Wear protective clothing and a face shield, or have a skilled mechanic do the battery maintenance. 196 Maintenance
