speeds greater than 50 km/h
(30 mph) to clean the DPF
effectively.
If the vehicle is used for numerous
short trips or extended slow-speed
operation, the engine computer may
not be able to adequately heat up
the exhaust system to clean the
DPF effectively. The engine
computer has been designed to
continuously monitor the condition
of the DPF. When the engine
computer detects that the DPF is
nearly full of particulates and that
the vehicle is not being operated in
a manner that would allow effective
automatic DPF cleaning, a Driver
Information Center (DIC) message
will display. Start the cleaning
process as soon as possible.
Cleaning Process
To activate the cleaning process,
continue driving safely, and keep
vehicle speed above 50 km/h (30
mph) until the warning message in
the DIC turns off.If the vehicle continues to be driven
with the DPF warning message on,
and the exhaust filter is not cleaned
as required, the malfunction
indicator lamp and the ENGINE
POWER IS REDUCED message
will come on. Dealer service is
necessary.
See
Malfunction Indicator Lamp
(Check Engine Light) 0127.
{Warning
During DPF self cleaning or
during extended idling while
parked, the exhaust system and
exhaust gases are very hot.
Things that burn could touch hot
exhaust parts under the vehicle
and ignite. You or others could be
burned. Do not park, or idle for an
extended period of time, near or
over papers, leaves, dry grass,
or other things that can burn.
Keep the exhaust area clear of
material that could ignite or burn.
See Parking over Things That
Burn 0196 for more information.
Diesel Exhaust Fluid
{Warning
Diesel Exhaust Fluid (DEF) is
corrosive. Do not allow it to come
in contact with your skin, eyes,
or the finished surfaces of the
vehicle. If exposed, it may cause
skin and eye irritation. Wear skin
and eye protection when
handling. Inhalation may cause
irritation to the upper respiratory
tract. Store in a cool,
well-ventilated area. For more
safety and storage information,
see the label of the Diesel
Exhaust Fluid container.
DEF is used with diesel engines to
reduce the amount of regulated
emissions produced. The fluid level
in the DEF tank must be maintained
for the vehicle to run correctly. The
capacity of the DEF tank is 18.5 L
(4.9 gal).

GMC Terrain/Terrain Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-10664916) - 2018 - crc - 9/15/17
Driving and Operating 199
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 GMC
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 service plan, OnStar
can help locate a DEF retailer. See
Customer Assistance Offices0371
for phone numbers to assist in
contacting a GM dealer. See
Recommended Fluids and
Lubricants 0361. 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 how to fill the
DEF tank, see
Filling the Tank
(Gasoline) 0247 orFilling the Tank
(Diesel) 0248.
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
Driver Information Center (DIC).
Exhaust fluid level status is
available on the DIC under the
Vehicle Information menu. See
“Diesel Exhaust Fluid (DEF)” in
Driver Information Center (DIC)
0 136.
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 may require less fluid to fill the
DEF tank.
The following actions describe
strategies required by the U.S.
Environmental Protection Agency
(EPA) and the California Air
Resource Board (CARB). The DEF
messages relate to these strategies.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
