Service via ASSYST: first at 25 000 km or 12 months, then alternating A/B services
Engines meet Euro 6d-TEMP with efficient petrol, diesel and plug-in hybrid options
Fuel use stays low across the range thanks to new efficient engines that meet Euro 6d-TEMP. Diesels and the plug-in hybrid deliver the strongest economy figures in mixed driving. A larger optional tank extends range for longer trips.
Servicing follows the ASSYST system with the first check at 25 000 km or one year. Later visits alternate between lighter A and fuller B services that cover oil, filters, brakes and fluids. Chain-driven engines avoid belt changes.
Safety kit is strong from the base model with Active Brake Assist that can stop for cars, pedestrians and cyclists, plus lane keeping and fatigue alerts. The five-star Euro NCAP score reflects solid structure and high adult and child protection scores.
Daily use benefits from the raised seating, flexible rear seats and power tailgate on higher trims. Regular ASSYST services and genuine parts keep the car reliable over years of family duty.
