Driving and Operating 197
In certain cold conditions, it is
possible to find some frozen DEF in
the DEF fill pipe opening. If this
condition prevents the filling of a
DEF tank, place the vehicle in a
warm garage overnight.
For information on how to fill the
DEF tank, seeFilling the Tank
(Gasoline) 0257 or
Filling the Tank (Diesel) 0258.
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 in the DIC. See “Diesel
Exhaust Fluid (DEF) Level (Diesel
Engine Only)” inDriver Information
Center (DIC) (Base and Midlevel)
0 124 or
Driver Information Center (DIC)
(Uplevel) 0130.
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.
If DEF is added under freezing
conditions, additional time may be
required to remove speed limitations
and it may require less fluid to fill
the DEF tank.
The DIC message EXHAUST
FLUID RANGE: XXXX km (mi)
displays at approximately 1 600 km
(1,000 mi) of fluid range remaining.
This message appears again at
approximately 500 km (300 mi) of
remaining range before the exhaust
fluid tank becomes empty.Below 500 km (300 mi) of range
remaining, these messages will
appear every time the vehicle is
started.
Below 121 km (75 mi) of range
remaining, the DIC message
EXHAUST FLUID LOW SPEED
LIMITED SOON displays. This
message will display every time the
vehicle is started.
If these warnings are ignored and
the DEF tank becomes empty, the
DIC message EXHAUST FLUID
EMPTY REFILL NOW - 563 KM
(350 MI) UNTIL 104 KM/H (65 MPH)
MAX SPEED displays. The
displayed mileage will decrease as
driving continues. A warning light
also comes on.
When the mileage countdown is
zero, the DIC message EXHAUST
FLUID EMPTY REFILL NOW -
TRANSITIONING TO 104 KM/H
(65 MPH) MAX SPEED displays.
A warning light and a chime also
come on. Vehicle speed will be
reduced to a maximum speed limit
of 104 KM/h (65 MPH).
