Carbureted (for earlier models) or multi-point fuel injection (MPI) depending on engine and market
Fuel Delivery Diesel:
Indirect injection with rotary or inline injection pumps
Timing Belt Replacement Interval:
Typically 60,000-80,000 km or 4-5 years, crucial for TU engines to avoid catastrophic failure
Standard Transmission Type:
5-speed manual gearbox
Optional Transmission Type:
3-speed or 4-speed automatic transmission (depending on market and engine)
Gearbox Codes:
Various manual gearbox codes like MA, ML, possibly JCD for automatic

Curb Weight:
Varies significantly by engine and body style, typically between 950 kg and 1200 kg
Gross Vehicle Weight Rating:
To be specified per model variant in the manual
Crash Test Results:
While Euro NCAP ratings were not as standardized in 1991, the ZX was designed with PSA's safety principles of the era.
Braking System:
Front ventilated discs, rear drums standard; optional ABS available on higher trims
Body Structure:
Rigid passenger cell with crumple zones designed to absorb impact energy
Seatbelts:
Pre-tensioned seatbelts likely standard on front seats
Audio System:
Typically a basic radio/cassette player with 4-6 speakers, optional CD player may have been available.
ABS:
Optional Anti-lock Braking System (ABS) available on certain trims, significantly enhancing braking safety.
Features:
Limited by era; focus on functional vehicle systems rather than modern connectivity.
Oil Change Interval:
Typically 10,000-15,000 km or annually, depending on usage and oil type (refer to manual for specific grades and intervals)
Spark Plug Replacement:
Varies by plug type (standard vs. platinum), often around 30,000-60,000 km
Engine Oil Type:
API SF/SG or ACEA A1/A2, viscosity typically 10W-40 or 15W-50, consult manual for precise grade based on climate
Coolant Type:
Ethylene glycol based, typically a 50/50 mix with distilled water (specific Citroen coolant spec important)
Brake Fluid Type:
DOT 3 or DOT 4, hygroscopic and requires periodic replacement (e.g., every 2 years)
Suspension:
Rear torsion bar suspension can wear and require adjustment/rebuilding; front suspension bushings prone to wear.
Electrical:
Corrosion on connectors, issues with dashboard illumination, and central locking actuators can occur.
Engine:
Head gasket leaks on higher mileage TU engines, timing belt failure if not replaced proactively.
Exhaust System:
Corrosion and eventual failure of exhaust components (muffler, pipes) due to age.
Clutch Replacement:
Wear and tear on clutch components over time, requiring replacement of clutch disc, pressure plate, and release bearing.
Citroen Philosophy:
Known for innovative suspension systems (though not Hydractive on the ZX), aerodynamic design, and comfortable ride.
Segment:
