1. Loosen the clamp that secures the air inlet tube to the engine airfilter 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.

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 to Adding
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 MERCON V should only use MERCONV fluid or fluid that
is specified dual usage MERCON/MERCON V. Refer toscheduled maintenance to 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.
