Driving and Operating
Vehicles with DPF have specific fuel
and engine oil requirements. See

for
more information on those
requirements.
Extended idling in P (Park) can
cause exhaust parts and gases to
become very hot. Keep the exhaust
area clear of material that could
ignite or burn. See
Parking Over
Things That Burn on page 9

for
more information.
For vehicles with Power Take
‐
Off
(PTO), monitor the instrument panel
cluster for lights related to the DPF.
All engines consume some amount
of engine oil. Ash is the by
‐
product
of engine oil combustion. The ash
will become trapped in the DPF over
the life of the vehicle. Eventually,
the buildup of ash will restrict the
exhaust gases and the DPF will
need to be cleaned or replaced.

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 information, see the label
of the Diesel Exhaust Fluid
container.
Diesel Exhaust Fluid (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
approximately 18.9 L (5 gal).
Locating Diesel Exhaust Fluid
DEF can be purchased at a
Chevrolet or GMC dealer. It can
also be purchased at authorized
vehicle and truck dealerships.
Additionally, some diesel truck
fuelling stations or retailers may
also have DEF for purchase. For
vehicles with an active OnStar
subscription, OnStar can help to
locate a DEF retailer. For more
