Fill the AdBlue tank on level ground and
with the vehicle switched off. When adding
AdBlue, it is recommended to fully fill the
AdBlue tank. For AdBlue tank capacity, see
. When
adding AdBlue to an empty tank or tank
approaching empty, always fully fill the
AdBlue tank and allow the vehicle to restart.
If AdBlue is added under freezing conditions,
it may require less fluid to fill the
AdBlue tank.
When fluid reaches the top of the AdBlue
filler pipe, stop filling. Do not top up the
AdBlue tank. If using a bottle or jug to refill
AdBlue, follow the instructions on the
container label and use a dedicated
filling aid.
Caution
Do not overfill the AdBlue tank and do
not allow AdBlue to make contact with
the finished surfaces of the vehicle, as it
could damage the vehicle finish. If AdBlue
is spilled during filling, wipe any affected
surface with a damp cloth.
When replacing the AdBlue cap, turn it
clockwise until it clicks. Make sure the cap is
fully installed.
Push the fuel/AdBlue hatch closed.

automatically display in the Driver
