🛡️ Safety Features
Ratings
Crash Test Results:
Data for this era is limited by modern standards; the manual would cover structural integrity and safety systems relevant to the time.
Active Features
Braking System Design:
Disc brakes front and rear on most models, with unique Citroën pedal design (brake pedal actuated brake pressure via hydropneumatic system).
Passive Features
Restraint System:
Coverage includes 'Restraint System', implying information on seatbelts and potentially early airbag systems if fitted to specific 1975 models/markets, though unlikely for standard fitment.
💡 Technology Features
Infotainment
Radio Options:
Likely factory-optional AM/FM radio. Manual may cover basic installation and troubleshooting.
Driver Assistance
Features:
Limited by modern standards. The defining 'technology' was the hydropneumatic self-leveling suspension and brake system.
🔧 Maintenance
Service Intervals
Oil Change Interval:
Typically 5,000-7,500 km (3,000-4,500 miles) for the era, or annually. The manual will provide specific intervals for the 1975 model.
Tune Up Interval:
Likely every 15,000-20,000 km (9,000-12,000 miles), covering spark plugs, ignition timing, and carburetor adjustment.
Fluid Specifications
Engine Oil:
Likely 20W-50 or 10W-40 API SE/SF grade for the air-cooled engine. Specific viscosity and API rating to be confirmed in the manual.
Hydraulic Fluid:
LHM (Liquide Hydraulique Minéral) for the hydropneumatic suspension and brake system. Specific type (e.g., LHM Plus) and capacity will be detailed.
Transmission Fluid:
Likely a GL-4 gear oil (e.g., 75W-90 or 80W-90). Specific grade and capacity to be detailed in the manual.
Known Issues
Rust And Corrosion:
Common for vehicles of this era, especially in certain climates. Manual likely covers body panel repair and rust prevention.
Hydropneumatic System:
Potential for leaks in lines, spheres needing service, or pump issues. Manual provides detailed diagnosis and repair for this signature system.
Electrical Gremlins:
As with many older European cars, electrical issues can arise. The detailed wiring diagrams are invaluable.
📚 Vehicle History
Brand Heritage
Citroen Innovation:
Citroën is renowned for pioneering automotive engineering, particularly its hydropneumatic suspension systems, front-wheel drive, and aerodynamic designs, all of which are core to the GS/GSA.
Model Evolution
Gs Introduction:
The Citroën GS was introduced in 1970 as a mid-size family car, intended to fill the gap between the Ami and the DS. It was lauded for its innovative design, excellent ride comfort, and aerodynamic styling.
Gsa Introduction:
The GSA was a significant facelift of the GS, launched in 1979. It featured revised styling (notably the front end inspired by the CX), an improved interior, and engine upgrades. This manual specifically covers the 1975 GS, but its inclusion of 'GSA' suggests some overlap in mechanical components or that the manual might cover the transition period, or that 'GSA' in the product name refers to the general lineage the manual supports.
Production
Manufacturing Location:
Primarily France, but also produced under license in other countries.
Production Period:
GS: 1970-1986; GSA: 1979-1986
🏆 Awards & Recognition
Recognitions
European Car Of The Year:
The Citroën GS was voted European Car of the Year in 1971.
Ratings
Design And Comfort:
Consistently praised for its advanced aerodynamic design and superior ride comfort compared to its contemporaries.
