Corrosion is present on battery terminals and the battery tray, leading to occasional starting issues.

Safety: Wear eye protection and gloves. Battery acid is corrosive.

• Clean terminals: Disconnect negative then positive cables. Neutralize corrosion with baking soda and water, then scrub with a wire brush.
• Protect terminals: After reassembly (positive first, then negative), apply a thin coat of dielectric grease or battery terminal spray.
• Inspect tray: Clean and repaint or replace a heavily corroded battery tray.
• Test battery: Load-test the battery and replace it if weak or older than its recommended service life.
