Curb Weight:
Curb weight typically ranged from 2,700 to 3,200 lbs (1225 - 1450 kg) depending on engine and equipment.
Crash Test Data:
Specific crash test ratings from official bodies like NHTSA or IIHS for this exact model year range may be limited or unavailable in modern databases. The manual would focus on the vehicle's built-in safety features.
ABS:
Anti-lock Braking System (ABS) was available as an option or standard on higher trims, particularly in later years of this generation. The manual will cover its operation and troubleshooting.
Airbags:
Driver-side airbag became more common during this period, and was likely standard on many models by 1992-1993. Passenger airbags were rare for this era. The manual will detail airbag system components and safety precautions.
Seat Belts:
Front and rear seat belts, with automatic tensioners on front belts becoming standard. Manual will detail seat belt system.
Oil Change Interval:
Typically every 3,000-5,000 miles (5,000-8,000 km) or 3-6 months, depending on driving conditions and oil type used. Consult manual for specific recommendations.
Timing Belt Replacement:
Crucial interval. Usually recommended between 60,000 to 90,000 miles (100,000 to 150,000 km). Failure to replace can cause catastrophic engine damage. Manual will provide precise interval and procedure.
Spark Plug Replacement:
Intervals vary by spark plug type (copper, platinum). Typically 30,000 miles for copper, 60,000+ for platinum. Manual will specify.
Engine Oil Type:
API SG or higher. Viscosity typically 10W-30 or 10W-40, but can vary with temperature. Consult owner's manual or the service manual for precise specifications.
Coolant Type:
