Crash Safety:
Information not readily available for specific crash ratings for this era and model, but design focused on occupant protection for its time.
Braking System:
Hydraulic disc brakes front, drum brakes rear (often with Citroën's brake pressure regulator)
Seatbelts:
Likely fitted with front seatbelts; rear seatbelt availability varied by market and trim.
Oil Change Interval:
Typically every 5,000-7,500 km or annually (refer to specific manual section for exact details).
Major Service Interval:
Every 20,000-30,000 km for comprehensive checks and fluid changes (refer to manual).
Engine Oil Type:
Viscosity grade typically 20W-50 or 10W-40 (API SE/SF or equivalent, refer to manual for precise specification).
Hydropneumatic Fluid:
LHM (Liquide Hydraulique Minéral) – Citroën's proprietary hydraulic fluid. Specific grade (e.g., LHS 200 or later LHM Plus) required.
Coolant:
For the oil cooler and any auxiliary water cooling systems, typically a long-life coolant mixture.
Brake Fluid:
DOT 3 or DOT 4 (ensure compatibility with Citroën's systems, consult manual).
Gearbox Oil:

Hydropneumatic System:
Potential leaks from seals, hoses, and the hydropneumatic accumulator (sphere) requiring regular inspection and potential replacement.
Engine Reliability:
Air-cooled engines can be susceptible to overheating if cooling fins are clogged or the oil cooler is inefficient. Carburetor tuning is critical.
Electrical System:
Corrosion in connectors, aging wiring, and issues with the fuse box are common for vehicles of this age.
Bodywork:
Rust and corrosion, particularly in wheel arches, sills, and subframes, are common issues.
Suspension Height Regulator:
The hydraulic spheres for the suspension can degrade over time, affecting ride height and comfort.
Citroen Innovation:
