Engine Identification Engine Code System: Citroën used specific engine identification codes which can be found within the manual for precise identification of engine variants. 🔧 Transmission Standard Transmission Transmission Type: Hydropneumatic semi-automatic transmission (Citroën's 'CC' transmission - Citroën Connecté) Optional Transmission Optional Transmission Type: 4-speed Manual Transmission (less common, often on base models or specific markets) Features Clutch Operation: Automated clutch operation for the hydropneumatic system, operated by a vacuum servo. Fluid Specifications Transmission Fluid Type: Refer to manual for specific LHM (Liquide Hydraulique Minéral) or equivalent fluid for the hydropneumatic system. Manual transmissions require specific gear oil. 📐 Dimensions Exterior Length: Approx. 3,990 mm (early Berline) Width: Approx. 1,610 mm (early Berline) Height: Approx. 1,400 mm (early Berline) Wheelbase: Approx. 2,470 mm Weights Curb Weight: Approx. 980-1100 kg (depending on variant) 🛡️ Safety Features Ratings Crash Test Ratings: Information on early crash test performance is limited for this era; manual will detail structural integrity and safety features as designed. Active Features Active Safety Features: Disc brakes (front), powerful hydraulic braking system, stable hydropneumatic suspension providing excellent road holding. Passive Features Passive Safety Features: Lap and diagonal seat belts (front and rear depending on trim), reinforced body structure, impact-absorbing steering column (typical for the era). 💡 Technology Features Infotainment Infotainment System: Basic for its era; typically AM/FM radio, often with manual tuning and speaker controls. GSA may have slightly more integrated radio systems. Driver Assistance Driver Assistance Features: Limited by modern standards. The primary 'assistance' was the self-levelling hydropneumatic suspension offering a smooth ride and consistent handling. Connectivity Connectivity Features: None by modern definition; features were purely mechanical and electrical systems of the vehicle itself. 🔧 Maintenance Service Intervals Oil Change Interval: Typically every 5,000-10,000 km or 6-12 months, refer to manual for specific recommendations.
