Driver Assistance Advanced Features: The primary technological innovation was the hydropneumatic suspension system, providing exceptional ride comfort and handling. Early models featured a directional headlight system. Connectivity Connectivity Features: None in the modern sense. Connectivity would be limited to basic wiring for lights, ignition, and instrumentation. 🔧 Maintenance Service Intervals Oil Change Interval: Typically every 5,000-7,500 km (or annually), depending on usage and oil type. Tune Up Interval: Recommended at 15,000-20,000 km for spark plugs, ignition timing, and carburetor adjustment. Fluid Specifications Engine Oil Type: Typically SAE 20W-50 or 10W-40 (air-cooled engines can be sensitive to oil quality and viscosity). Coolant Type: N/A (Air-cooled engine) Brake Fluid Type: DOT 3 or DOT 4 Hydropneumatic Fluid: LHM (Citroën's mineral-based hydraulic fluid) Known Issues Common Faults: Hydropneumatic system leaks (especially spheres and seals), rust (particularly sills, wheel arches, and suspension mounts), ignition system issues (coil, distributor), carburetor wear, and electrical gremlins are common in older vehicles. Common Issues Details Suspension Wear: The characteristic self-levelling suspension requires specific maintenance and replacement of hydraulic fluid and spheres periodically. Body Corrosion: As with many cars of this era, rust prevention and treatment are crucial for longevity. 📚 Vehicle History Brand Heritage Manufacturer Origins: Citroën, a French automotive manufacturer known for innovative and often avant-garde designs. Model Evolution Gs Introduction: The Citroën GS was introduced in 1970, replacing the Ami 8 and offering a more modern and aerodynamic design.
