134Driving and operatingFilling station9Danger
Follow the operating and safety
instructions of the filling station
when refilling AdBlue.
1. Switch off engine and remove key
from ignition switch.
2. Disengage the cover using a suitable screwdriver and remove.
3. Unscrew protective capanticlockwise from the filler neck.
4. Fully insert the pump nozzle intothe filler neck and switch it on.
5. When refilling is complete, mount the protective cap and turn
clockwise until it engages.
6. Replace the cover by inserting the
right side first.
AdBlue canister Note
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.
Note
Since AdBlue has a limited
durability, check the date of expiry
before refilling.
1. Switch off engine and remove key
from ignition switch.
2. Disengage the cover using a suitable screwdriver and remove.
3. Unscrew protective cap anticlockwise from the filler neck.

Driving and operating135
4. Attach the adapter (located inglovebox) to 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 adapter.
7. Lift the canister until it is empty. 8. Unscrew the hose from the filler neck adapter.
9. Remove the adapter and return to
its container in the glovebox.
10. Mount the protective cap and turn
clockwise until it engages.
11. Replace the cover.
Note
Dispose of AdBlue canister and
hose according to environmental requirements.
Note
If an AdBlue refill is not detected,
drive continuously for 10 minutes,
keeping vehicle speed above
20 km/h.
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.
Note
If less than 10 litres of AdBlue have
been refilled during the last 2 years,
the remaining fluid should be
exchanged since AdBlue has a
limited durability. Seek the
assistance of a workshop.
Disregard could lead to damage to
the selective catalytic reduction
system.
Filler cap
Only use genuine filler caps. AdBlue
tank has a special filler cap.Fault
If the system detects an operating
fault, control indicator Y illuminates
together with a warning chime. Seek
the assistance of a workshop
immediately.
A corresponding message may
appear in the Driver Information
Centre 3 91.

Service and maintenance203Engine oil viscosity
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 3 206.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze. 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 concentrationshould 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 fluidOver 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 3 131.
