warm water and baking soda. Coat the terminals with
grease to prevent further corrosion.

turned off before performing maintenance.
When checking the battery, remove the ground
cable first and reinstall it last.

for how much to mix with water.

Do not use engine antifreeze or any other
substitute because it may damage your vehicle's
