200 STARTING AND OPERATING
(Continued)
2. Insert DEF fill adapter/nozzle into DEF fill
inlet.
NOTE:
The DEF gauge may take up to five
seconds to update after adding a gallon
or more of Diesel Exhaust Fluid (DEF) to
the DEF tank. If you have a fault related
to the DEF system, the gauge may not
update to the new level. See an autho
-
rized dealer for service.
The DEF gauge may also not immediately
update after a refill if the temperature of
the DEF fluid is below 12°F (-11°C). The
DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update
after a period of run time. Under very cold
conditions, it is possible that the gauge
may not reflect the new fill level for
several drives.
Excessive overfilling of the DEF tank can
result in a MIL lamp/fault code and inac-
curate level readings.
Refilling With Nozzles
You can fill up at any DEF distributor.
Proceed as follows:
Insert the DEF nozzle in the filler, start
refilling and stop refilling at the first
shut-off (the shut-off indicates that the
DEF tank is full). Do not proceed with the
refilling, to prevent spillage of DEF.
Extract the nozzle.
Refilling With Containers
Proceed as follows:
Check the expiration date.
Read the advice for use on the label
before pouring the content of the bottle
into the DEF tank.
If systems which cannot be screwed in
(e.g. tanks) are used for refilling, after the
indication appears on the instrument
panel display
Ú page 115 fill the DEF
tank with no more than 2 Gallons
(8 liters).
If containers which can be screwed to the
filler are used, the reservoir is full when
the DEF level in the container stops
pouring out. Do not proceed further.
CAUTION!
To avoid DEF spillage, and possible
damage to the DEF tank from overfilling, do
not “top off” the DEF tank after filling.
DO NOT OVERFILL. DEF will freeze below
12ºF (-11ºC). The DEF system is designed
to work in temperatures below the DEF
freezing point, however, if the tank is over-
filled and freezes, the system could be
da
maged.
When DEF is spilled, clean the area imme-
diately with water and use an absorbent
ma
terial to soak up the spills on the ground.
Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank
as it can result in severe damage to your
engine, including but not limited to failure
of the fuel pump and injectors.
