POWER STEERING FLUID
•2.3L I4 engine
•3.0L V6 engine
•4.0L V6 engine
Check the power steering fluid. Refer to the service maintenance section
for the service interval schedules.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).

2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be between the MIN
and MAX lines. Do not add fluid if the level is within this range.
5. If the fluid is low, add fluid in small amounts, until it reaches
between the MIN and MAX lines. Refer toMaintenance product
specifications and capacitiesin this chapter for the proper fluid
type.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the “MIN” and
“MAX” lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range the performance of the
system could be compromised; seek
service from your authorized dealer
immediately.
CLUTCH FLUID (IF EQUIPPED)
Check the fluid level. Refer toscheduled maintenancefor the service
interval schedules.
During normal operation, the fluid level in the clutch reservoir should
remain constant. If the fluid level drops, refill the fluid level to the step
in the reservoir.
Use only a DOT 3 brake fluid designed to meet Mazda specification.
Refer toMaintenance product specifications and capacitiesin this
chapter.
WARNING: Carefully read cautionary information on product
label. For MEDICAL EMERGENCY INFORMATION contact a
physician or Poison Control Center immediately. Failure to
follow these instructions may result in personal injury.

1. Clean the reservoir cap before
removal to prevent dirt and
water from entering the
reservoir.
2. Remove cap and rubber
diaphragm from reservoir.
3. Add fluid until the level reaches
the step in the reservoir.
4. Reinstall rubber diaphragm and
cap onto reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid
•Refer toscheduled maintenance informationfor scheduled check
and change intervals.
•Transmission does not consume fluid.
•Check fluid when transmission is not operating properly or if you see
a leak.
•Fluid level must be checked at normal operating temperature, 20 miles
(30 km) of driving.
To check and add fluid:
1. Drive the vehicle 20 miles (30 km) to reach normal operating
temperatures.
2. If driven in hot weather, city traffic, pulling a trailer, allow
transmission to cool for 30 minutes before checking.
3. Engage parking brake, start engine.
4. Put your foot on the brake pedal and move the gearshift lever slowly
through all of the gear ranges.
5. Shift to P (Park) and leave the engine running.
6. Remove the dipstick, wipe clean with a dry lint free rag.
7. Install and fully seat the dipstick into the filler tube.
8. Remove the dipstick and inspect
the fluid level. Level should be
in the cross-hatched area.

CHECKING AND ADDING REAR DIFFERENTIAL FLUID
1. Park the vehicle on a level
surface.
2. Engage the parking brake fully –
put in first gear.
3. Ensure the vehicle cannot move.
4. Clean the filler plug.
5. Remove the filler plug and
inspect the fluid level.
6. Fluid level should be at the
bottom of the opening.
7. Add enough fluid through the
filler opening so that the fluid
level is at the bottom of the
opening.
8. Install and tighten the fill plug
securely.
Use only fluid that meets Mazda specifications. Refer to the
Maintenance product specifications and capacitiessection in this
chapter.
AIR FILTER
Refer toscheduled maintenancefor the appropriate intervals for
changing the air filter element.
When changing the air filter element, only use a genuine Mazda air filter
element.
WARNING: To reduce the risk of vehicle damage and/or
personal burn injuries do not start your engine with the air
cleaner removed and do not remove it while the engine is
running.
1. Loosen the clamp that secures the air inlet tube to the engine air
filter cover and disconnect the tube from the cover (for V6 only).
2. Release the clamps that secure the air filter housing cover.

3. Carefully separate the two
halves of the air filter housing.
4. Remove the air filter element from the air filter housing.
5. Wipe the air filter housing and cover clean to remove any dirt or
debris and to ensure good sealing.
6. Install a new air filter element.
Be careful not to crimp the
filter element edges between
the air filter housing and cover.
This could cause filter damage
and allow unfiltered air to enter
the engine if not properly
seated.
7. Replace the air filter housing cover and secure the clamps.
8. Replace the air inlet tube and secure the clamp.
Note:Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.

1Brake fluid will drop slowly as the brakes wear and will rise when brake components are replaced.
Fluid levels below the MAX line that do not trigger the brake warning light are within the normal
operating range, there is no need to add fluid. If the levels are outside the normal operating range,
the performance of your brake system could be compromised, seek service from your authorized
dealer immediately.2Add the coolant type originally equipped in your vehicle. Do not mix different colors or types of
coolant. Do not use Mazda Extended Life Engine Coolant (orange in color). Refer toAdding
engine coolant, in this chapter.3Service refill capacity is determined by filling the transmission to the bottom of the filler hole with
the vehicle on a level surface.4Automatic transmissions that require MERCONV should only use MERCONV fluid or fluid that
is specified dual usage MERCON/MERCONV. Refer toscheduled maintenanceto determine
the correct service interval. Use of any fluid other than the recommended fluid may cause
transmission damage.5Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with an in-tank cooler. The amount of transmission fluid and fluid level should be set
by the indication on the dipstick’s normal operating range.6Traction-Lok axles use 4.75–5.0 pints (2.2–2.4L) of rear axle lubricant. Add 4 oz. (118 ml) of
Additive Friction Modifier meeting Mazda specifications for complete refill of Traction-Lok axles.
Service refill capacities are determined by filling the rear axle 1/4 inch to 9/16 inch (6 mm to 14
mm) below the bottom of the filler hole.
If submerged in water, the rear axle lubricant should be changed.
