The AdBlue filler neck is located immediately be­
side the diesel filler neck. Add at least the
amount of AdBlue displayed in the instrument
cluster. If
you
do not refill this amount of
fluid,

the system may not detect that the tank has
been refilled and it may not be possible to restart
the engine. You can refill with a maximum of 12

litres.

Important: A message in the instrument cluster
display informs you if
you
need to refill AdBlue.

•
Park the vehicle on a level surface.

•
Switch off the ignition.

A WARNING
AdBlue can cause irritation to the
skin,
eyes,
and respiratory organs. Wash thoroughly with
clean water should you come into contact
with this
fluid.
Seek medical assistance if nee­

ded.

© CAUTION
- Use only
AdBLue
that complies with the ISO
22241-1 standard. Do not mix AdBlue with
additives and do not dilute it with water.
- AdBlue must not be added to the diesel
tank, and diesel must not be added to the
AdBlue tank. Never start the engine if you
fill up with the wrong type of
fuel,
as this
could damage the tank system and the en­

gine.
Obtain professional assistance.
-AdBlue attacks surfaces such as paintwork,
plastic veneer and carpets. Remove spilt
flu­

id as soon as possible with a damp cloth and
plenty of water. If the AdBlue has already

solidified,
use warm water and a sponge.
Residues of AdBlue solidify after
a
while if
they are not removed and can damage the
affected surface.
- Do not keep refill bottles or canisters in the
vehicle, as AdBlue can leak and damage the
vehicle interior.
- Keep AdBlue away from clothing. Wash
thoroughly with clean water should you
come into contact with this
fluid.
