130Driving and operatingCentre 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
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 87.
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.
When 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 AdBlue
Page 133 of 239

Driving and operating131Caution
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 3 224.
Filling station9 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.
3. Unscrew protective cap anticlockwise from the filler neck.
4. Fully insert the pump nozzle into the filler neck and switch it on.
Page 134 of 239

132Driving and operating5. When refilling is complete, mountthe 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.
Notice
Let the vehicle idle for 10 seconds to
allow the system to detect the
AdBlue refill.
Failure to observe this procedure will result in the system only recognising
the AdBlue refill after 20 minutes of
driving.
If the AdBlue refill is detected
successfully, AdBlue level warnings
will disappear.
If the AdBlue refill is not detected
some time after running the engine,
seek the assistance of a workshop.
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.

202Service and maintenanceEngine 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 3 205.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free 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.
This concentration should be
maintained all year round. The use of additional coolant additives that
intend to give additional corrosionprotection or seal against minor leaks
can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will be rejected.
Brake 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 3 128.
