Airbags:
Driver's side airbag (SRS) was standard on most markets.
Chassis Design:
Reinforced chassis with crumple zones.
Audio System:
Factory fitted radio/cassette player with optional CD changer, typically 4-speaker system. Wiring diagrams will show compatibility for upgrades.
ABS:
As mentioned in safety, ABS was a significant technological feature for its time.
None:
No modern connectivity features (Bluetooth, USB, etc.) as expected for a 1994 vehicle.
Oil Change Rotary:
Frequent oil changes are critical for rotary engines. Typically recommended every 3,000-5,000 miles (5,000-8,000 km) or as per the owner's manual, with specific attention to rotary-specific oil.
Spark Plugs:
Specific platinum or iridium spark plugs designed for rotary engines, with recommended replacement intervals.
Engine Oil Type:
Rotary-specific synthetic oil (e.g., API SG/SH or higher) with adequate viscosity (e.g., 10W-30 or 10W-40 depending on climate). The manual would specify exact grades.
Coolant Type:
Mazda/Dexron III compatible coolant or equivalent. Specific coolant type is crucial for rotary engine cooling.
Brake Fluid:
