Manual will detail safety systems. Active Features Braking System: Discs front, Drums rear (often with a self-leveling hydraulic pressure regulator) Passive Features Seat Belts: Front seat belts standard, optional rear belts Body Structure: Unitary body construction with integral safety cage 💡 Technology Features Infotainment Radio: Optional AM/FM radio, often with basic analog tuning. Driver Assistance Braking System Enhancements: Self-leveling hydraulic system for consistent braking performance and ride height. Connectivity Connectivity Features: N/A (Pre-digital era) 🔧 Maintenance Service Intervals Oil Change: Typically every 5,000 - 7,500 km (3,000 - 4,500 miles) or annually. Manual will specify exact intervals and oil type. Transmission Fluid Change: Recommended every 30,000 - 50,000 km (18,000 - 30,000 miles). Manual will detail procedure and fluid capacity. Fluid Specifications Engine Oil Type Gs: Specific air-cooled engine oil, likely a monograde (e.g., SAE 30) or a specific multigrade with low detergency for older engines. Manual is critical for this. Engine Oil Type Gsa: Similar to GS, but might accommodate slightly different specifications depending on engine updates. Manual is critical. Brake Fluid Type: DOT 3 or DOT 4 Hydraulic Fluid (Manual will confirm specific requirements, especially considering potential Citroën LHS fluid for older brake systems, though unlikely for 1975 GS brakes). Cooling System Fluid: Air-cooled; no coolant required. Known Issues Hydropneumatic Suspension: Potential for leaks, loss of ride height. Manual provides repair and maintenance procedures. Electrical System: Can be complex; wiring diagrams in the manual are essential for troubleshooting. Rust: Common on classic cars of this era, especially in certain climates. Bodywork sections in manual are relevant. 📚 Vehicle History Brand Heritage Citroen Design Philosophy: Innovation, aerodynamic efficiency, comfort, and unique engineering solutions (e.g., hydropneumatic suspension) Model Evolution Gs Introduction: Introduced in 1970 as a replacement for the Ami 8, positioned as a mid-size family car. Gsa Introduction: Introduced in 1979 as an updated version of the GS, featuring revised styling (especially the front end) and improved interior ergonomics.
