🛡️ Safety Features

Crash Test Data:

Likely no formal Euro NCAP or equivalent ratings for this era. Manual will detail passive safety features.

Braking System Type:

Front: Ventilated discs; Rear: Discs. Citroën's characteristic LHM hydraulic system powers the brakes, offering progressive feel and often incorporating anti-lock braking systems (ABS) on higher trims.

Steering System:

Power-assisted rack and pinion or DIRAVI (Directionality by Variable Resistance) on some models for variable steering effort.

Restraint System:

Front seatbelts (inertia reel), provision for rear seatbelts. Airbags were not standard on most CX models during this period, but manual may cover optional fitment.

Body Construction:

Self-supporting body shell with integrated safety crumple zones.

💡 Technology Features

Audio Systems:

Factory fitted radio/cassette players, often with speakers in doors and rear shelf. Manual will cover removal, installation, and basic troubleshooting.

ABS:

Anti-lock Braking System (ABS) was an option on many later models. Manual will detail its operation, diagnosis, and repair.

Diravi Steering:

Variable resistance steering system for enhanced high-speed stability and low-speed ease of use. Manual will cover its operation and adjustment.

Vintage Features:

Focus is on mechanical and electrical systems rather than modern connectivity. Features would include power windows, central locking (on higher trims), and climate control.

🔧 Maintenance

Oil Change Interval:

Typically 5,000 - 10,000 km or 6-12 months, depending on driving conditions and oil type specified. Manual will provide exact intervals.

Hydropneumatic Fluid Change:

LHM (Liquide Hydraulique Minéral) fluid change and filter replacement are critical and typically recommended every 40,000 - 60,000 km. Manual will detail this process.

Engine Oil Grade:

Varies by engine. Common grades include 10W-40, 15W-40, or 20W-50. Manual will specify API service categories (e.g., SF, SG).

Coolant Type:

Ethylene glycol based antifreeze/coolant mixture. Manual will specify correct ratio and type.

Transmission Fluid:

Manual transmission: GL-4 or GL-5 gear oil. Automatic transmission: Specific ATF (Automatic Transmission Fluid) type, e.g., Dexron II or equivalent. Manual will detail exact type and capacity.

Brake Fluid:

DOT 3 or DOT 4 brake fluid, though primarily LHM is used for hydraulic functions. Manual will clarify.

Common Cx Problems:

Hydropneumatic system leaks (spheres, seals, height correctors), electrical gremlins, rust in common areas (wheel arches, sills), timing belt wear (on relevant engines), exhaust system corrosion.

Troubleshooting Guidance:

Manual provides an advanced troubleshooting guide to diagnose and rectify these and other potential issues.
