Optional AM/FM radio, often with basic analog tuning.

Braking System Enhancements:

Self-leveling hydraulic system for consistent braking performance and ride height.

Connectivity Features:

N/A (Pre-digital era)

🔧 Maintenance

Oil Change:

Typically every 5,000 - 7,500 km (3,000 - 4,500 miles) or annually. Manual will specify exact intervals and oil type.

Transmission Fluid Change:

Recommended every 30,000 - 50,000 km (18,000 - 30,000 miles). Manual will detail procedure and fluid capacity.

Engine Oil Type Gs:

Specific air-cooled engine oil, likely a monograde (e.g., SAE 30) or a specific multigrade with low detergency for older engines. Manual is critical for this.

Engine Oil Type Gsa:

Similar to GS, but might accommodate slightly different specifications depending on engine updates. Manual is critical.

Brake Fluid Type:

DOT 3 or DOT 4 Hydraulic Fluid (Manual will confirm specific requirements, especially considering potential Citroën LHS fluid for older brake systems, though unlikely for 1975 GS brakes).

Cooling System Fluid:

Air-cooled; no coolant required.

Hydropneumatic Suspension:

Potential for leaks, loss of ride height. Manual provides repair and maintenance procedures.

Electrical System:

Can be complex; wiring diagrams in the manual are essential for troubleshooting.

Rust:

Common on classic cars of this era, especially in certain climates. Bodywork sections in manual are relevant.
