Refilling AdBlueCaution
Only use AdBlue that complies
with European standards
DIN 70 070 and ISO 22241-1.
Do not use additives.
Do not dilute AdBlue.
Otherwise the selective catalytic
reduction system could be
damaged.
Notice
Only use the designated AdBlue canisters for refilling to prevent a
topping up of too much AdBlue.
Additionally the fumes in the tank are captured in the canister and do not
emerge.
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
Notice
A volume of at least 5 litres of AdBlue
must be added when refilling.
Otherwise the refilling of AdBlue
might not be detected by the system.
If AdBlue must be refilled at
temperatures below -11 °C, the
refilling of AdBlue might not be
detected by the system. In this case,
park the vehicle in a space with a
higher ambient temperature until
AdBlue is liquefied.
Notice
When unscrewing the protective cap from the filler neck, ammonia fumesmight emerge. Do not inhale as the
fumes have a pungent smell. The
fumes are not harmful by inhalation.
The vehicle must be parked on a level surface.
The filler neck for AdBlue is located
behind the fuel filler flap.
The fuel filler flap is located at right rear side of the vehicle.The fuel filler flap can only be opened
if the vehicle is unlocked.
1. Remove key from ignition lock.
2. Close all doors to avoid ammonia fumes entering the interior of the
vehicle.

Fuel for petrol enginesOnly use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable of running
with E10 fuel that fulfills these
standards. E10 fuel contains up to
10 % bioethanol.
Use fuel with the recommended
octane rating 3 271. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly increases fuel consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
