AdBlue General information The selective catalytic reduction
(BlueInjection) is a method to
substantially reduce the nitrogen
oxides in the exhaust emission. This
is achieved by injecting a Diesel
Exhaust Fluid (DEF) into the exhaust system.
The designation of the DEF used is AdBlue Ⓡ 1)
. It is a non-toxic, non-
flammable, colourless and odourless
fluid which consists of 32% urea and
68% water.9 Warning
Avoid contact of your eyes or skin
with AdBlue.
In case of eye or skin contact,
rinse off with water.
Caution
Avoid contact of the paintwork with AdBlue.
In case of contact, rinse off with water.
AdBlue freezes at a temperature of
approx. -11 °C. As the vehicle is
equipped with an AdBlue pre-heater,
the emissions reduction at low
temperatures is ensured. The AdBlue
pre-heater works automatically.
Level warnings The AdBlue consumption is approx.4000 mpg and depends on the driving
behaviour.
If the AdBlue level falls below a
certain value, a level warning AdBlue
Range: 1500 mi will be displayed in
the Driver Information Centre (DIC).
A volume of at least 5 litres of AdBlue
must be refilled as soon as possible.
Driving is possible without any
restrictions.
If AdBlue is not refilled within a certain distance, further level warnings are
displayed in the DIC depending on
the current AdBlue level. Later on
requests to refill AdBlue and finally
the announcement to prevent an
engine restart are displayed. These
restrictions are a legal requirement.
At an AdBlue range of 560 miles, the
following warning messages are
alternately displayed in the DIC:
■ AdBlue Low Refill Now
■ Engine Restart Prevented in 560
miles
Additionally, the control indicator Y
flashes continuously and a warning
chime sounds four times every
three minutes.1) Registered trademark of the Verband der Automobilindustrie e.V. (VDA).

Vehicles with misfuel inhibitor9Warning
Do not try to open the flap of the
fuel filler neck manually on
vehicles with misfuel inhibitor.
Disregarding this could lead to
trapping of the fingers.
Vehicles with a selective catalytic
reduction system are equipped with a
misfuel inhibitor.
The misfuel inhibitor ensures that the flap of the fuel filler neck can only be
opened by using a nozzle for diesel
fuel or a funnel for emergency
refilling.
Turn the fuel filler cap slowly anti-
clockwise.
The cap can be retained in the
bracket on the fuel filler flap.
Place the nozzle in straight position to
the filler neck and press with slight
force to insert.
In case of an emergency refilling with a canister, a funnel must be used to
open the cap of the filler neck.The funnel is located in the load
compartment.
Place the funnel in straight position to the filler neck and press with slight
force to insert.
Use the funnel to fill in the diesel fuel
into the filler neck.
After topping-up, put the funnel into
the plastic bag and stow it in the storage compartment.
