Maintenance
|
|
Service Intervals
|
|
Oil Change Interval:
|
Typically every 7,500 - 10,000 km (4,500 - 6,000 miles) or 6-12 months, depending on driving conditions and oil type used. Consult manual for specifics.

|
|
Known Issues
|
|
Hydropneumatic System:
|
Leaking spheres, failing hydraulic pumps, worn seals in suspension components, low fluid levels, malfunctioning height correctors. Regular checks and fluid changes are vital.
|
|
Electrical Gremlins:
