REAGENT TANK
(2/4)
Filling (continued)
The tank can be filled at the pump. With
the ignition off, insert the nozzle and
insert it fully before turning it on to fill
the fuel tank (risk of splashing).
No more than two filling operations may
be made after the feed has switched off
automatically for the first time because
there must be room for expansion in the
tank.
In other filling cases, it is essential to
read the information shown on the re-
agent container (e.g. the can or bottle).
Precautions for use
When filling:
– handle the reagent with care. They
can damage clothes, shoes, body-
work components etc. ;
– make sure that no water enters the
fuel tank.

If the reagent overflows, or contami-
nates any paintwork, clean the affected
area quickly with plenty of cold water
and a soft cloth.
Note: If the reagent crystallises, use a
soft sponge.
In extreme cold weather conditions
In frosty weather conditions, the rea-
gent tank should be refilled when the

indicator and the message "Top
Up AdBlue before 1200 km" appear on
the instrument panel.
Special cases
The reagent fluid freezes below about
-10°C.
In these conditions, do not attempt fill-
ing when the fluid is frozen. In the event
of needing to top up or fill the tank with

reagent ( on), park the vehicle
in a hotter location if possible so that
the reagent becomes liquid again.
Otherwise, have a qualified profes-
sional top up or fill up with reagent fluid.
After filling the reagent tank, check
that the cap and cover are closed,
start the engine and WAIT 10 sec-
onds with the vehicle stationary,
engine running before setting off
again.
If this operation is not carried out,
the filling of the tank will not be
taken into account automatically
until after several dozens of minutes
of driving.
The message "--- TOP UP AdBlue"
and/or the warning lights will con-
tinue to appear until the filling has
been taken into account by the
system.
No work whatsoever is
permitted on any part of
the system. To prevent
damage, only qualified per-
sonnel from our network may work
on the system.
