Form No. 8R09-EA-02G
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. This air filter may be cleaned with
compressed air and reused, or replaced,
depending on its condition. Unless it is
very dirty, simply shake it to remove
foreign particles. Each time you inspect it,
wipe inside the air cleaner housing with a
damp cloth.


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.

Customer Information and Reporting Safety Defects
Wa r r a n t y
Form No. 8R09-EA-02G
Government regulations in the United States and Canada require that automobiles meet
specific emission regulations and safety standards. Therefore, vehicles built for use in the
United States, its territories, and Canada may differ from those sold in other countries.
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.
Outside the United States and Canada

Customer Information and Reporting Safety Defects
Wa r r a n t y
Form No. 8R09-EA-02G
Non-genuine parts and accessories for Mazda vehicles can be found in stores.
These may fit your vehicle, but they are not approved by Mazda for use with Mazda
vehicles. When you install non-genuine parts or accessories, they could affect your
vehicle’s performance or safety system; the Mazda warranty doesn ’t cover this. Before you
install any non-genuine parts or accessories, consult an Authorized Mazda Dealer.
Mazda assumes no responsibility for death, injury, or expenses that may result from the
installation of add-on non-genuine parts or accessories.
Add-On Non-Genuine Parts and Accessories
Installation of Non-Genuine Parts or Accessories:
Installation of non-genuine parts or accessories is dangerous. Improperly designed
parts or accessories could seriously affect your vehicle’ s performance or safety system.
This could cause you to have an accident or increase your chances of injuries in an
accident. Always consult an Authorized Mazda Dealer before you install non-genuine
parts or accessories.
Add-On Electrical and Electronic Equipment:
Incorrectly choosing or installing improper add-on equipment or choosing an
improper installer is dangerous. Essential systems could be damaged, causing engine
stalling, air-bag (SRS) activation, ABS inactivation, or a fire in the vehicle.
Be very careful in choosing and installing add-on electrical equipment, such as
mobile telephones, two-way radios, stereo systems, and car alarm systems.
