Compatibility: Windows, Mac, Linux OS Software Requirement: Adobe Reader ⚙️ Engine Specifications Primary Engine Engine Options: While the specific engine variant isn't detailed, the CX in these years commonly featured petrol engines. The CX 20 typically had a 2.0L engine (XM7) and the CX 25 variants used 2.5L engines (often the Douvrin J engine). Diesel variants (CX 25 D) were also available. Manual will cover all these. Performance Typical Horsepower Range: Approx. 100-130 hp for petrol variants, lower for diesel. Fuel System Fuel Delivery: Likely fuel injection for later models (e.g., CIS-Jetronic or Bosch L-Jetronic depending on market and engine) and possibly carbureted options for base models or specific markets. Turbocharged variants (CX Turbo) were also produced. 🔧 Transmission Standard Transmission Types: Available with 5-speed manual and 3-speed automatic transmissions. Optional Transmission Types Optional: Automatic transmission was optional. Features Transmission Features: Emphasis on smooth operation, particularly with the automatic transmission. 📐 Dimensions Exterior Body Styles: Saloon (Berline), Estate (Break), and potentially the CX-Break Coupé (though less common). Wheelbase: Approx. 2,950 mm (116.1 in) for Berline. Weights Curb Weight: Varies significantly by model and engine, typically around 1,300-1,500 kg (2,866-3,307 lb). 🛡️ Safety Features Ratings Historical Safety Standards: While formal Euro NCAP ratings were not prevalent for this era, the CX was designed with passive safety in mind, including a robust chassis and energy-absorbing crumple zones. The hydropneumatic suspension contributes to stable handling. Active Features Active Safety Features: Power assisted steering, anti-lock braking system (ABS) often optional or standard on higher trims. Passive Features Passive Safety Features: Seat belts, impact-absorbing dashboard, reinforced door beams. 💡 Technology Features Infotainment Audio System: Factory fitted radio/cassette player, with potential for aftermarket upgrades. Speaker configurations varied by trim level. Driver Assistance Steering System: DIRAVI (Direction à rappel asservi) - a hydraulically assisted steering system that provides variable assistance, becoming firmer at higher speeds. This is a key technological feature. Connectivity Early Electronics: While not 'connected' in the modern sense, the CX featured advanced (for its time) electronic ignition systems, power windows, and central locking on higher trims. 🔧 Maintenance Service Intervals Oil Change Interval: Typically every 5,000-7,500 miles (8,000-12,000 km) or annually, depending on driving conditions. The manual will provide precise intervals. Timing Belt Replacement: Dependent on engine, usually around 30,000-50,000 miles (50,000-80,000 km). Critical to follow manual's recommendation. Fluid Specifications Hydropneumatic Fluid: Citroën LHS 2 (or compatible mineral-based hydraulic fluid). The manual will specify the exact type and capacity. Engine Oil Specification: Varies by engine, but typically a 10W-40 or 15W-40 semi-synthetic or mineral oil meeting API SF or SG standards. Manual will be definitive. Brake Fluid: DOT 3 or DOT 4. Manual will confirm. Known Issues Common Wear Items:...
