a replacement oil filter is used that does not meet Mazda Material and
design specifications, start-up engine noises or knock may be experienced.

It is recommended you use the appropriate Mazda oil filter (or another
brand meeting Mazda specifications) for your engine.
BATTERY
Your vehicle is equipped with a
Mazda maintenance-free battery
which normally does not require
additional water during its life of
service.
However, for severe usage or in high temperature climates, check the
battery electrolyte level. Refer to theService Maintenance Sectionfor
the service interval schedules.
Keep the electrolyte level in each cell up to the “level indicator”.
Do not overfill the battery cells.
If possible, try to only fill the battery cells with distilled water. If the
battery needs water often, have the charging system checked.
If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
Note: Electrical or electronic accessories or components added to
the vehicle by the dealer or the owner may adversely affect
battery performance and durability.
