Combined fuel use around 8 l/100 km or 35 UK mpg for the 2.0 petrol.
Service uses fixed intervals of oil change every 10,000 miles or 1 year, or LongLife flexible up to 20,000 miles or 2 years.
Standard safety includes ESP, ABS, EBD, front and side airbags plus Sideguard head protection.
IIHS rates the frontal crash protection as Good for this generation.
The 2.0 petrol engine returns combined fuel economy of about 8 litres per 100 km, or roughly 35 miles per UK gallon, with urban figures higher and extra-urban lower. CO2 sits near 192 g/km under Euro 4 rules. Real-world use typically exceeds the official combined figure slightly depending on conditions and driving style.
Servicing follows either a fixed regime with oil and filter changes every 10,000 miles or 12 months, plus interval inspections, or the LongLife flexible system that can stretch oil services to a maximum of 20,000 miles or two years based on conditions. Brake fluid and pollen filters need attention every two years. Higher-mileage items such as air filters and spark plugs on petrol engines fall due around 40,000 to 60,000 miles.
Safety equipment is comprehensive for the period, with electronic stability programme, anti-lock brakes, electronic brake-force distribution, traction aids, dual front airbags, front side airbags and the Sideguard curtain system all standard. Seat-belt pre-tensioners cover all positions. The generation carries a Good rating from IIHS for moderate-overlap frontal protection, with Euro NCAP results from the closely related prior model showing four stars for adult occupants.
Keeping the car involves regular oil changes with the correct specification fluid to protect the engine long-term, especially on petrol variants. Check service history carefully for timing-belt work where fitted and any Multitronic transmission fluid services. The galvanised body resists corrosion well when maintained, and standard features like the full-size spare and Thatcham Category 1 alarm support everyday ownership.
