Early digital displays were experimental. Driver Assistance Steering System: DIRAVI speed-sensitive power steering. Braking System: Early application of Anti-lock Braking System (ABS) on some models. Connectivity Not Applicable: No modern connectivity features like Bluetooth or USB. 🔧 Maintenance Service Intervals Oil Change: Every 7,500 - 10,000 km (approx. 5,000 - 6,000 miles) or annually. Filter Change: Oil filter with every oil change; Air filter every 20,000 - 30,000 km. Spark Plugs: Every 30,000 - 40,000 km. Hydropneumatic System: Regular inspection of spheres, fluid levels, and seals; specific intervals detailed in the manual. Fluid Specifications Engine Oil: API SE/SF, SAE 10W-40 or 15W-50 (refer to manual for exact specification). Coolant: Ethylene glycol based antifreeze mixture (50/50 with distilled water). Hydropneumatic Fluid: LHM (Citroën's own hydraulic fluid), typically LHS 20 prior to 1982 and LHM Plus after, but 1980 is transitional. Consult manual for precise type (e.g., LHS 20 or early LHM variants). Known Issues Hydropneumatic System Wear: Spheres and seals can degrade over time, leading to ride height issues or harshness. Fluid leaks are common if not maintained. Electrical Gremlins: Wiring harnesses can become brittle, leading to intermittent faults in various systems. Fuse box contacts can corrode. Rust Prone Areas: Wheel arches, sills, door bottoms, and boot floor are susceptible to corrosion. Engine Cooling: Radiator and cooling hoses require regular inspection due to age and potential for leaks. 📚 Vehicle History Brand Heritage Citroen Legacy: Citroën has a long history of automotive innovation, particularly with hydraulic systems (2CV, DS, SM), aerodynamic design,...
