the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period, fuel and
engine oil consumption may be
higher and the cleaning process of
the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging of the vehicle battery.

To restart the engine, the tank must be filled with AdBlue first.
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
might not be detected by the system.
If AdBlue must be refilled at
temperatures below -11 °C, the
refilling of AdBlue might 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 fumesmight 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.
