146Driving and operatingNotice
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
refilling the tank completely or with a volume of at least ten litres of AdBlue(depending on AdBlue
consumption).
Avoid minor top-ups (e.g. less than
ten 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 3 242.
Filling station
9 Danger
Follow the operating and safety

when refilling AdBlue.
1. Switch off engine and remove key
from ignition switch.
2. Open right-hand door and pull fuel
filler flap to open.
3. Unscrew blue protective cap anticlockwise 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.
Driving and operating147AdBlue canisterNotice
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. Open right-hand door and pull fuel
filler flap to open.3. Unscrew blue 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, or
until the flow from the canister has stopped. This can take up to five
minutes.
7. Place the canister on the ground to empty the hose, wait 15
seconds.
8. Unscrew the hose from the filler neck.
9. Mount the protective cap and turn
clockwise until it engages.
10. Close filler flap and right-hand door.
Notice
Dispose of AdBlue canister
according to environmental
requirements. Hose can be reused
after flushing with clear water before
AdBlue dries out.Notice
Allow the vehicle to idle for at least
ten 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 approx.
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.
