Displacement:
2179 cc (2.2 Liters)
Valvetrain:
DOHC (Double Overhead Camshafts), 16 valves
Horsepower:
Approx. 136 PS (134 bhp / 100 kW) at around 4000 rpm
Torque:
Approx. 317 Nm (234 lb-ft) at around 2000 rpm
Fuel Injection:
Common Rail Direct Injection (CRDi) with piezoelectric injectors
Turbocharger:
Variable Geometry Turbocharger (VGT)
Emission Control:
Diesel Particulate Filter (DPF) likely equipped for Euro 4 compliance
Type:
6-speed Manual Transmission
Type:
4-speed Automatic Transmission (AL4 variant likely)
Manual Gear Ratios:
Specific ratios detailed within the manual.
Automatic Features:
Tiptronic sequential shifting, comfort/sport modes.
Manual Transmission Fluid:
Refer to manual for specific GL-4 or GL-5 specification and viscosity (e.g., 75W-80, 75W-90).
Automatic Transmission Fluid:
Specific ATF fluid (e.g., Mobil ATF LT 71141 or equivalent) required for AL4 transmission.
Engine Oil And Filter:
Typically every 20,000 km (12,500 miles) or 1 year, whichever comes first, for HDi engines (refer to manual for precise recommendation).
Fuel Filter:
Recommended replacement every 60,000 km (37,500 miles) or as per manual. Crucial for common rail systems.
Air Filter:
Check every 20,000 km (12,500 miles), replace as needed or typically every 40,000 km (25,000 miles).
Timing Belt:
For the DW10ATED4 engine, the timing belt typically requires replacement around 120,000 km (75,000 miles) or 5 years. This is a critical maintenance item.
Coolant:
Long-life coolant, typically an OAT-based (Organic Acid Technology) antifreeze, such as PSA specific coolant (e.g., 'Peugeot-Citroën Blue' or equivalent).
Brake Fluid:
DOT 4 brake fluid.
Power Steering Fluid:
Specific hydraulic fluid for Citroen's Hydractive system (LHM Plus or similar is NOT used for power steering, it's a separate system; typically ATF or specialized fluid for the pump/rack).
Hydropneumatic Suspension:
Spheres can lose pressure, pump issues, leaks in hydraulic lines, height corrector problems. The manual provides repair procedures.
Diesel Particulate Filter:
DPF regeneration issues, clogging due to short trips or incorrect driving cycles. Requires diagnostic tools for forced regeneration or replacement.
Electrical Gremlins:
Citroen's multiplexed electrical systems can sometimes be prone to minor electrical faults; comprehensive wiring diagrams in the manual are essential.
Automatic Transmission:
The AL4 automatic transmission can sometimes exhibit 'limp mode' issues or solenoid problems. Proper fluid maintenance and diagnostics are crucial.
Citroen Design Philosophy:
Citroen is renowned for its innovative engineering, particularly in suspension systems (DS, SM, CX) and passenger comfort.
C5 First Generation:
Launched in 2001, replaced the Xantia. Known for its distinctive styling and advanced Hydractive 3 suspension.
Facelift 2004:
A significant facelift occurred in 2004, introducing updated styling, interior refinements, and improved technology, making this manual highly relevant for this updated model.
