reservoir regularly. It should be kept at
MAX.

Adding Clutch Fluid
If the fluid level is low, add fluid until it
reaches MAX.
Before adding fluid, thoroughly clean the
area around the cap.
Spilled Brake Fluid:
Spilled brake fluid is dangerous. If it
gets in your eyes, they could be
seriously injured. If this happens,
immediately flush your eyes with
water and get medical attention.
Brake fluid spilled on a hot engine
could cause a fire. Be careful not to
spill brake fluid on yourself or on the
engine.
Low Brake Fluid Levels:
Low brake fluid levels are dangerous.
Low levels could signal brake lining
wear or a brake system leak. Your
brakes could fail and cause an
accident. If you find a low fluid level,
have the brakes inspected.
• Brake fluid will damage painted
surfaces. If brake fluid does get on
a painted surface, wipe it off
immediately.
• Using nonspecified brake fluids
(page 10-4) will damage the system.
Mixing different fluids will also
damage it.
If the brake system frequently
requires new fluid, consult an
Authorized Mazda Dealer.

Inspecting Power Steering Fluid
Level
Inspect the fluid level at each engine oil
change. Add fluid if necessary; it does not
require periodic changing.
The level must be kept between the H and
L marks.
Visually examine the lines and hoses for
leaks and damage.
1. Park on a level surface, well off the
right-of-way, and set the parking brake
firmly.
2. Turn off the engine and allow it to cool.
•
Clutch fluid will damage painted
surfaces. If clutch fluid does get on
a painted surface, wipe it off
immediately.
• Using nonspecified clutch fluids
(page 10-4) will damage the system.
Mixing different fluids will also
damage it.
If the clutch system frequently
requires new fluid, it should be
inspected. Consult an Authorized
Mazda Dealer immediately.
NOTE
Low clutch fluid level may signal a
fluid leak. If you find a low fluid level,
have the clutch inspected.

3. Remove the filler cap and attached dipstick.
4. Wipe them clean and put them back.
5. Remove again and inspect the level.
6. It must be between H and L. Add fluid if necessary.
Don ’t overfill.
If new fluid is required frequently, consult
an Authorized Mazda Dealer.

Inspecting Automatic
Transmission Fluid Level
The automatic transmission fluid level
should be inspected regularly. Measure it
as described below.
The volume of fluid changes with the
temperature. For that reason, it is best to
examine the level after having driven the
vehicle for 15 minutes. If necessary,
however, it can also be inspected without
driving when the outside temperature is
above 20
°C (70 °F).
1. Park on a level surface and set the parking brake firmly.
2. Idle the engine. Push down on the brake pedal.
3. Move the shift lever through all ranges and set it at P.
Automatic Transmission
Fluid (ATF)
•Low fluid level causes transmission
slippage. Overfilling can cause
foaming, loss of fluid, and
transmission malfunction.
• Use specified fluid (page 10-4). A
nonspecified fluid could result in
transmission malfunction and
failure.
• The vehicle should not be driven if
the fluid level is below the bottom
of the dipstick and the outside
temperature is above 20
°C (70 °F),
or if evident automatic transmission
fluid leaks are found.

4. With the engine still idling, pull out the dipstick, wipe it clean.
5. Put the dipstick back into the filler tube and make sure it is fully seated.
6. Pull the dipstick out and read the fluid level.
The proper fluid level is marked on the
dipstick as follows.
Fluid hot scale
When checking the fluid level at normal
operating temperature, the fluid level
should be within the FULL and LOW
marks on the dipstick. Fluid cold scale
When the vehicle has not been driven but
the engine is idling, and the outside
temperature is above 20
°C (70 °F), the
fluid level should be close to, but not
above, the bottom notch on the dipstick.
Fully insert the dipstick. When adding
fluid, inspect with the dipstick to make
sure it doesn ’t pass full.
Sudden Vehicle Movement:
Shifting the shift lever without first
depressing the brake pedal is
dangerous. The vehicle could move
suddenly and cause an accident.
Make sure the brake pedal is applied
before shifting the shift lever.

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.

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

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.

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.
