🛡️ Safety Features

Crash Test Information:

Detailed structural analysis and component safety relevant to the era, though formal NCAP ratings were not common for this period

Braking System Design:

Advanced hydropneumatic braking system with pressure regulators and often ventilated front discs; some models featured ABS (Anti-lock Braking System) later in production

Seat Belts:

Front and rear seat belts

Chassis Structure:

Designed with crumple zones and a robust unibody structure

💡 Technology Features

Radio System:

Factory-fitted or aftermarket radios, often with basic AM/FM reception and cassette players

ABS:

Interior Controls:

Unique dashboard layout with 'mushroom' style controls for secondary functions on some early models

🔧 Maintenance

Oil Change Interval:

Typically every 10,000 km (6,000 miles) or 12 months, whichever comes first (specifics vary by engine and oil type)

Suspension Fluid Service:

Regular checking and topping up of hydropneumatic suspension fluid (LHM - Liquide Hydraulique Minéral) is critical, with periodic system flushes recommended

Timing Belt Replacement:

Essential for interference engines, typically every 60,000 - 80,000 km (37,000 - 50,000 miles), crucial to prevent catastrophic engine damage

Engine Oil:

API SF/SG or higher, viscosity grades like 10W-40 or 15W-50 depending on climate (refer to manual for exact specifications)

Hydropneumatic Fluid:

Citroën's LHM (Liquide Hydraulique Minéral) - the correct green mineral-based hydraulic fluid is paramount for suspension and brake systems

Coolant:

Ethylene glycol-based antifreeze with corrosion inhibitors, typically a 50/50 mix with distilled water

Suspension Leaks:

Common issues include wear in suspension spheres, seals, and hydraulic lines, potentially leading to 'sagging' or uneven ride height

Electrical Gremlins:

Older wiring harnesses and connections can degrade, leading to intermittent electrical faults

Rust And Corrosion:

Typical for vehicles of this age, particularly in areas prone to salt and moisture, affecting body panels and structural components

Engine Peripherals:

Wear on components like alternators, starter motors, and cooling fans can occur
