Driving and operating125Caution
Fuel grades other than those listedon page 3 148, 3 201 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
If control indicator Z flashes, the
permitted emission limits may be
exceeded. Lift your foot off the
accelerator until Z stops flashing and
is steadily illuminated. Contact a
workshop immediately.
Malfunction indicator light 3 84.
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 Ⓡ. It is a non-toxic, non-
flammable, colourless and odourless
fluid which consists of 32% urea and
68% water.
Notice
AdBlue Ⓡ is a registered trademark
of the Verband der
Automobilindustrie e.V. (VDA).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.
126Driving and operatingAdblue gauge
The current fluid level remaining is
shown in the Adblue gauge 3 79.
Level warnings
The AdBlue consumption is approx.
3.5 litres per 1000 km and depends
on the driving behaviour.
Version with level warnings in the
Driver Information Centre (DIC)
If the AdBlue level falls below a
certain value, a level warning will be
displayed in the Driver Information
Centre (DIC) 3 89.
Additionally, control indicator Õ
illuminates continuously together with a warning chime.
Refill the Adblue tank as soon as
possible. Refer to " Refilling AdBlue"
below.
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.
Engine restarts prevented
Subsequent requests to refill AdBlue
and finally the announcement that an engine restart will be prevented are
displayed in the DIC.
Notice
These restrictions are a legal
requirement.
Before the prevention of an engine
restart, a warning message with
0 miles is displayed in the DIC,
indicating that after switching off the
ignition an engine restart will be
prohibited.
After the prevention of an engine
start, a warning message is displayed in the DIC reminding the driver that
AdBlue level is insufficient.
To allow the engine to be restarted,
the tank should be filled with at least
10 litres of AdBlue.High emission warnings
If the exhaust emission rises above a
certain value, warnings similar to the
range warnings as described above
will be displayed in the DIC. Control
Driving and operating127indicator Õ illuminates continuously
together with A 3 85 and a warning
chime.
Requests to have the exhaust system
checked and finally the
announcement that an engine restart
with be prevented are displayed in the DIC.
Notice
These restrictions are a legal
requirement.
At an AdBlue range of approx.
680 miles, a warning message is
displayed in the DIC showing the
remaining distance the vehicle can
travel before engine restarts are
prevented. This warning message is
repeated approx. every 60 miles.
Seek the assistance of a workshop as
soon as possible.Version without level warnings in the Driver Information Centre (DIC)
When the Adblue gauge shows the
level is very low, control indicator Õ
first illuminates continuously, then as
Adblue level drops to a certain
amount Õ flashes for a few seconds
then illuminates continuously.
Refill the Adblue tank as soon as
possible. Refer to " Refilling AdBlue"
below.
Driving is possible without any
restrictions.
Engine power loss
As the Adblue level drops further,
control indicator Õ flashes for a few
seconds then illuminates
continuously, accompanied by a
warning chime and loss of engine
power.
Notice
These restrictions are a legal
requirement.
If AdBlue is not refilled before the tank
is empty, Õ flashes and after the next
engine restart the vehicle speed will
be limited to approx. 12 mph.
Refill immediately with at least
10 litres of AdBlue.High emission warnings
If the exhaust emission rises above a
certain value, control indicator Õ
illuminates together with A 3 85.
Consult a workshop as soon as
possible.
If the fault is not rectified within a
certain distance, Õ and A flash for
a few seconds then illuminate
continuously. Loss of engine power.
128Driving and operatingWhen the fault is critical, Õ and A
flash continuously and after the next
engine restart the vehicle speed will
be limited to approx. 12 mph.
Notice
These restrictions are a legal
requirement.
Seek the assistance of a workshop as
soon as possible.
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
If AdBlue must be refilled at very low temperatures, 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.
Notice
If engine starting is prohibited due to low Adblue level, we recommend
adding a volume of at least 10 litres
of AdBlue when refilling. Avoid minor
top-ups (e.g. less than 5 litres),
otherwise the system may not detect a refill.
Notice
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 filler flap located on the
right-hand side of the vehicle.
The filler flap can only be opened if the vehicle is unlocked and the right-hand door is opened.9 Danger
Vehicles with stop-start system:
The engine must be switched off
and the ignition key removed, to
avoid risk of engine being
restarted automatically by the
system.
Capacities 3 218.
Filling station
9 Danger
Follow the operating and safety
instructions of the filling station
when refilling Adblue.
1. Switch off engine and remove key
from ignition switch.
2. Pull filler flap to open.
Driving and operating129
3. Unscrew protective capanticlockwise from the filler neck.
4. Fully insert the pump nozzle into the filler neck and switch it on.
5. When refilling is complete, mount the protective cap and turn
clockwise until it engages.
6. Close filler flap and right-hand door.
AdBlue canister 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.
Notice
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
1. Switch off engine and remove key
from ignition switch.
2. Pull filler flap to open.
3. Unscrew protective cap anticlockwise from the filler neck.
4. Open AdBlue canister.
5. Mount one end of the hose on the
canister and screw the other end
on the filler neck.
6. Lift the canister until it is empty.
7. Unscrew the hose from the filler neck.
8. Mount the protective cap and turn
clockwise until it engages.
9. Close filler flap and right-hand door.
Notice
Dispose of AdBlue canister and
hose according to environmental requirements.
Filler cap
Only use genuine filler caps. Adblue
tank has a special filler cap.
Fault
If the system detects an operating fault, control indicator Õ illuminates
together with A and a warning
chime. Seek the assistance of a
workshop immediately.
Depending on version, a
corresponding message may also
appear in the DIC 3 89.
