% flashes and a warning chime
sounds several times when diesel particle filter has reached the
maximum filling level. Start cleaning
process immediately to avoid
damage to the engine.
Cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 revolutions per minute.
Shift down if necessary. Diesel
particle filter cleaning is then started.
If additionally a message appears in
the Driver Information Centre that
cleaning is not possible, seek the
assistance of a workshop.Caution
If the cleaning process is
interrupted, there is a risk of
provoking severe engine damage.
Cleaning takes place quickest at high engine speeds and loads.
The 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 3 210, 3 279 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 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.1) Registered trademark of the Verband der Automobilindustrie e.V. (VDA).
162Driving and operating9Warning
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.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 DIC.
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 (DIC).
Driving and operating163
Requests to have the exhaust systemchecked 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.
Notice
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.
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 3 213.
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.
164Driving and operating
8. Unscrew the hose from the fillerneck.
9. Mount the protective cap and turn
clockwise until it engages.
Notice
Dispose of AdBlue canister and
hose according to environmental requirements.
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.Caution
Disregard could lead to damage to
the selective catalytic reduction
system.
Automatic transmission
The automatic transmission permits
automatic gearshifting (automatic
mode) or manual gearshifting
(manual mode).
Manual shifting is possible in manual
mode by tapping the selector lever or pulling the steering wheel paddles
3 166.
Transmission display
The mode or selected gear is shown
in the transmission display.
In automatic mode, the driving
programme is indicated by D in the
Driver Information Centre (DIC).
In manual mode, M and the number
of the selected gear is indicated.
R indicates reverse gear.
N indicates neutral position.
P indicates park position.
Service and maintenance273
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 276.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 276.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37°C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional
coolant additives will be rejected.
Brake and clutch fluid Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.AdBlue
Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 161.
