Fuel use depends on the engine chosen. Diesel models return the strongest economy figures in normal driving while plug-in hybrids allow short electric-only trips when charged. Petrol versions suit lower annual mileage. Real-world returns sit below official claims once options and driving style are factored in.
Servicing follows the ASSYST system which calculates intervals based on use, commonly one year or around 15,500 miles. Plans such as ServiceCare spread costs and cover recommended items. A three-year unlimited-mileage warranty is standard with optional extensions.
Safety equipment is comprehensive from the base model. Active Brake Assist, PRE-SAFE, Blind Spot Assist and ATTENTION ASSIST come as standard along with a full set of airbags. Optional Driving Assistance packages add adaptive cruise, lane keeping and more. The structure earned a five-star Euro NCAP result for the generation.
Keeping the car is straightforward with the self-levelling rear axle that maintains height when loaded. Regular dealer servicing keeps the ASSYST system accurate and preserves residual value. Higher grades add features that reduce daily effort such as powered tailgate and keyless entry.
