Driving and operating143The control indicator % extinguishes
as soon as the self-cleaning
operation is complete.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 178, 3 241 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.
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 this fluid 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.
A volume of at least 5 litres of AdBlue must be refilled as soon as possible.
Driving is possible without any
restrictions.
1) Registered trademark of the Verband der Automobilindustrie e.V. (VDA).
144Driving and operatingIf AdBlue is not refilled within a certaindistance, further level warnings are
displayed in the Driver Information Centre 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 Driver
Information Centre:
● 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.
Before the prevention of the engine
restart is activated, the following
warning messages:
● AdBlue Empty Refill Now
● Engine Will Not Restart
are alternately displayed in the Driver
Information Centre.Additionally, the control indicator Y
flashes continuously and a warning
chime sounds four times every
three minutes.
After the prevention of the engine
start, the following message:
Refill AdBlue To Start Vehicle
will be displayed.
To restart the engine, the tank must be filled with AdBlue first.
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 Driver
Information Centre.
Requests to have the exhaust system checked and finally the
announcement to prevent an engine
restart are displayed. These
restrictions are a legal requirement.
Seek your workshop for assistance.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
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.
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
Driving and operating145Notice
A volume of at least 5 litres of AdBlue
must be added when refilling.
Otherwise the refilling of AdBlue
may not be detected by the system.
In case AdBlue refill is not
successfully detected:
1. Continuously drive the vehicle for 10 minutes making sure that
vehicle speed is always higher
than 12 mph.
2. If AdBlue refill is detected successfully, AdBlue supply
driven limitations will disappear.
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.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 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 3 179.
4. Unscrew protective cap from the
filler neck.
5. Open AdBlue canister.
6. Mount one end of the hose on the
canister and screw the other end
on the filler neck.
7. Lift the canister until it is empty.
8. Unscrew the hose from the filler neck.
9. Mount the protective cap and turn
clockwise until it engages.
Notice
Dispose of AdBlue canister and
hose according to environmental
requirements.
