Airbags:
Driver and front passenger airbags standard; side airbags available on some later models.
Seat Belts:
3-point front and rear seat belts; pretensioners and load limiters for front belts.
Engine Oil Change Interval:
Typically every 5,000 to 7,500 miles (8,000 to 12,000 km) or 6 months, whichever comes first, depending on driving conditions. Consult manual for specific recommendation.
Transmission Fluid Change Interval:
Recommended every 30,000 to 60,000 miles (48,000 to 96,000 km). Check manual for exact interval and procedure.
Coolant Replacement Interval:
First replacement typically at 60,000 miles (96,000 km) or 5 years, then every 30,000 miles (48,000 km) or 2 years thereafter.
Timing Belt Replacement Interval:
Crucial for this engine. Typically every 60,000 to 90,000 miles (96,000 to 144,000 km). Failure can cause catastrophic engine damage.
Engine Oil Specification:
API SG/SH or higher, SAE 5W-30 or 10W-30 (consult owner's manual for specific viscosity based on temperature).
Coolant Specification:
Ethylene glycol-based coolant (Mazda FL22 or equivalent).
Brake Fluid Specification:

Miller Cycle Engine Quirks:
Potential for carbon buildup in the intake manifold and cylinder head due to the supercharger and unique combustion cycle. Requires specific maintenance procedures. Supercharger belt and pulley wear can occur.
Automatic Transmission Reliability:
Some reports of premature wear or failure if not maintained properly. Fluid changes are critical.
Suspension Component Wear:
Bushing wear (control arms, sway bars) can lead to noise and poor handling. Ball joints and tie rod ends are also wear items.
Electrical Component Aging:
As with many cars of this era, aging electrical components (e.g., window motors, door lock actuators, power antenna, sensors) can fail.
Climate Control System Issues:
HVAC control panel failures, blower motor resistor issues, and refrigerant leaks can affect climate control functionality.
