Driving and Operating
DEF Fill - Vans
For vans, the DEF fill is behind the
fuel fill door. The DEF cap is blue,
and the diesel cap is green.
The fill tube location for chassis-cab
and cutaway vans finished by an
upfitter will vary. Check the upfitter
manual.
DEF Fill - Pickups
For full-size pickups, the DEF fill is
under the hood, on the passenger
side, at the back of the engine
compartment. The DEF cap is blue.
Exhaust Fluid Low
A full DEF tank will last for several
thousand kilometers (miles),
depending on vehicle usage. As the
exhaust fluid level drops, warnings
will automatically be displayed in the
DIC. Exhaust fluid level status is
available on the DIC under the
vehicle Information button.
See
“
Exhaust Fluid Level
”
in
Driver
Information Center (DIC) on
page 5-11
.
To avoid vehicle speed limitations,
the DEF tank should be refilled at
the first opportunity after a low
warning indication. If DEF is added
before the EXHAUST FLUID
EMPTY REFILL NOW message
appears, it may take several km/mi
for the DIC message to update.
If the vehicle speed has been
limited and DEF has been added, it
may take up to 30 seconds after
engine start with the vehicle
stopped for the EXHAUST FLUID
EMPTY REFILL NOW message to
clear. If the vehicle is driven prior to
the DIC message clearing, the
vehicle speed will still be limited.
If the DIC message clears while
driving, the speed limitation will be
removed gradually.
