208 STARTING AND OPERATING
(Continued)
DEF FILL PROCEDURE
NOTE:
For the correct fluid type Ú page 430.
Remove cap from DEF tank (located on drivers side
of
the vehicle or in fuel door).
Fill Locations
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 authorized
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 (-1°C). The DEF tank
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.
At 40°F (4°C) you could see some increase in
the DEF gauge due to the tank thawing. The
gauge and level sensor are working properly and
is just updating with proper thawed DEF.
Excessive overfilling of the DEF tank can result
in a MIL lamp/fault code and inaccurate 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.
After the indication appears on the instrument
panel display Ú page 101 fill the DEF tank with
no more than 4 Gallons (15 Liters).
1 — Diesel Exhaust Fluid (DEF) Fill Location
2 — Diesel Fuel Fill Location
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 overfilled and freezes,
the system could be damaged.
When DEF is spilled, clean the area immedi-
ately with water and use an absorbent material
t
o
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.
