Standard Gearbox Type:
Likely a 6-speed automatic transmission (e.g., ZF 6HP26) for V6 models and potentially manual for some diesel variants, though automatic was dominant.
Optional Gearbox Type:
While automatic was prevalent, a manual gearbox might have been offered on certain diesel derivatives.
Automatic Transmission Features:
Adaptive shift control, manual sequential shifting mode (Tiptronic-style).
Automatic Transmission Fluid Type:
Likely requires specific Dexron or Mercon compatible fluids, or a proprietary PSA fluid (e.g., LT 71141, or equivalent for ZF 6HP26).
Oil Change Interval:
Typically 20,000 km (12,500 miles) or 2 years, whichever comes first. May vary by engine and oil specification.
Timing Belt Replacement Interval:
For petrol engines, often 120,000 km (75,000 miles) or 10 years. Diesel engines may use chains or have different interval requirements.
Air Filter Replacement:
Recommended every 40,000-60,000 km or as per manual, subject to driving conditions.
Cabin Filter Replacement:
Typically annually or every 20,000 km.
Engine Oil Specification Petrol:
e.g., PSA B71 2300, ACEA A3/B4, API SL/CF rated synthetic oil (e.g., 0W-30, 5W-40).
