If AdBlue refill is still not detected
seek the assistance of a workshop.
If AdBlue must be refilled at
temperatures below -11 °C, the
refilling of AdBlue may not be
detected by the system. In this case,
park the vehicle in a space with a
higher ambient temperature until
AdBlue is liquefied.
Note
When unscrewing the protective cap
from the filler neck, ammonia fumes
may 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.
3. Pull fuel filler flap at the recess
and open 3 211.
4. Unscrew protective cap from the

Note
Dispose of AdBlue canister and

Exchanging AdBlue
If less than 5 litres of AdBlue have
been refilled during the last 2 years,
the remaining fluid should be
exchanged since AdBlue has a
limited durability. Seek the assistance
of a workshop.
Caution
Disregard could lead to damage to
the selective catalytic reduction
system.
