The average AdBlue ®
consu mption is between 1%
and 5% of fuel consum ption. Like fuel consump-
tion, AdBlue ®
consu mption is high lydependent
upon driving style and operating conditions. For
th is reason, your vehicle's actual consu mption /g-
ures in da y-to -day operating conditions may di.er from
the consum ption /gures calculate d. The fre-
qu ency at which you will ha veto to p up AdBlue ®
will also vary. Ha vetheAd Blue ®

at a quali/ed specialist workshop before making

WARNING
ARNING Risk of an accident due to
va pour poc kets form ing in the brake sys-
tem
The brake 0uid constantly absorbs moisture
from the air. This lo wersthe boiling point of
th e brake 0uid. If the boiling point is too lo w,
va pour poc kets may form inthe brake system
when the brakes are applied hard.
This impairs the braking e.ect. #
Have the brake 0uid rene we d at the
speci/ed inter vals. Ha
ve the brake 0uid regula rly re placed at a quali-
/ed specialist workshop.
Only use a brake 0uid appr ovedby Mercedes-
