fluid, inspect with the dipstick to make
sure it doesn ’t pass full.

All moving points of the body, such as
door and hood hinges and locks, should
be lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.
Make sure the engine hood’s secondary
latch keeps the hood from opening when
the primary latch is released. A viscous paper air filter fits inside the air
cleaner housing, as shown. It
’s been
specially treated and should not be
cleaned and reused. Replace it when
necessary.

Replacing the Air Filter
1. Unfasten the clamps.
Body LubricationAir Filter
Don
’t drive without an air filter. This
could result in excessive engine wear.
NOTE
If the vehicle is operated in very dusty
or sandy areas, replace the filter more
often than recommended intervals.

The differences may make it difficult or even impossible for your vehicle to receive
satisfactory servicing in other countries. We strongly recommend that you NOT take your
Mazda outside these areas.
You may have these problems if you do:
•Recommended fuel may be unavailable. Any kind of leaded fuel or low-octane fuel will
affect vehicle performance and damage the emission controls and engine.
• Proper repair facilities, tools, testing equipment, and replacement parts may not be
available.
The Mazda warranty applies only to Mazda vehicles registered and normally operated in
the United States, its territories, and Canada.
