GMC Terrain: Driving and Operating / Diesel Exhaust Fluid
Warning
Avoid getting Diesel Exhaust
Fluid (DEF) on your skin or in
your eyes as it could cause
irritation. For more safety,
handling, and storage information,
see the Diesel Exhaust Fluid
container label.
Diesel Exhaust Fluid (DEF) is used
with diesel engines to reduce the
amount of regulated emissions
produced. Products such as AdBlue
are types of DEF, and are approved
for use in the vehicle as long as
they have an API certification label
or meet ISO 22241.The fluid level in
the DEF tank must be maintained
for the vehicle to run properly. DEF
is not a fuel additive. DEF should
not be mixed with or added to diesel
fuel. DEF freezes when exposed to
temperatures below −11 °C (12 ° F).
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 your
dealer. It can also be purchased at
authorized vehicle and truck
dealerships. Additionally, some
diesel truck fueling stations or
retailers may have DEF for
purchase. For vehicles with an
active OnStar or connected services
plan, OnStar can help to locate a
DEF retailer. See Customer
Assistance Offices for phone
numbers to assist in contacting a
GM dealer. See Recommended
Fluids and Lubricants.

system filters soot particles out of
the exhaust gases. The DPF is
under the vehicle in the exhaust
system.

monitored by the engine computer,
the DPF will need to be cleaned of
accumulated solids...
Caution
Use only DEF that is GM
approved, or fluid containing the
