Lubrication
Oil Grade Petrol:	Typically API SF or SG classification, viscosity grades like 10W-40 or 15W-50 depending on climate. Specifics in manual.
Oil Grade Diesel:	Typically API CD or CE classification for diesel engines, viscosity grades like 15W-40. Specifics in manual.

Transmission
Standard
Manual Transmission:	Commonly equipped with 4-speed or 5-speed manual transmissions (e.g., Citroën JX or Peugeot MA gearboxes).
Optional
Automatic Transmission:	Optional on some models, often the ZF 3HP22 3-speed automatic.
Features
Clutch Type:	Hydraulically operated dry single-plate clutch.
Fluid Specifications
Automatic Transmission Fluid:	Likely Dexron II or equivalent, but exact specification must be confirmed from manual.

Dimensions
Exterior
Body Styles:	Primarily a 5-door hatchback. Estate (Break) and coupé versions were also available in certain markets/iterations.
Wheelbase:	Approximately 2650 mm (104.3 inches).
Length:	Around 4150 mm (163.4 inches) for the hatchback.
