224 Driving and Operating
It is normal to hear the DEF system
purge fluid back into the tank after
the vehicle is shut off.
Locating Diesel Exhaust Fluid
DEF can be purchased at a
Chevrolet dealer. It can also be
purchased at authorized vehicle
dealerships. Additionally, some
diesel fueling stations or retailers
may have DEF for purchase. For
vehicles with an active OnStar
subscription, OnStar can help to
locate a DEF retailer. See Customer
Assistance Offices 0 388 for phone
numbers to assist in contacting a
GM dealer. See Recommended
Fluids and Lubricants 0 378.
Filling the DEF Tank
Caution
Use only DEF that is GM
approved, or fluid containing the
API certified or ISO 22241 label.
The use of other fluids could
damage the system, requiring
costly repairs that will not be
covered by the vehicle warranty.
When adding DEF to an empty or
very low tank, always add at least
7.6 L (2 gal) of fluid to release the
vehicle from speed limitation.
To prevent damage to the system,
do not overfill the DEF tank. When
fluid reaches the top of the fill pipe,
stop filling. Do not top off the
DEF tank.
If you spill DEF during filling, wipe
any affected surface with a damp
cloth.
For information on the DEF tank,
see Filling the Tank (Gasoline)
0 263 or Filling the Tank (Diesel)
0 265.
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 Level (DEF) (Diesel
Engine Only) in Driver Information
Center (DIC) 0 137.
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.
