dependent upon driving style and operating con‐
ditions. Forth is reason, your vehicle's actual
consum ption figures under da y-to -day ope rating
conditions may di ffer from the consum ption fig‐
ures calculated. The frequency at which you will
ha ve to to p up AdBlue ®

Europe. Before a longer stay outside of Europe,
consult a qualified specialist workshop.
