In Brief 1-3
Special DPF Driver Messages
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, the Driver
Information Center will display a
message. See Diesel Particulate
Filter Messages on page 5-14.
If the vehicle continues to be driven
in a manner that prevents effective
DPF cleaning, the DPF will become
plugged with particulates. If this
occurs, the engine computer will
turn on the service engine soon light
in the instrument cluster and the
DIC will display the message
ENGINE POWER IS REDUCED.
See Diesel Particulate Filter on
page 9-12 and Engine Power
Messages on page 5-13.
Fuel
Use Ultra Low Sulfur Diesel
Fuel (ULSD)
Use ULSD only. The emission
control hardware used on the
vehicle may be damaged by using
fuel with high sulfur levels. Use only
fuel that is dispensed from pumps
bearing the ULSD label.
Do Not Use Low Sulfur Diesel
Fuel (LSD)
Do not use fuel that is dispensed
from pumps bearing the LSD label.
Do Not Use Non-Highway Fuel
Fuel labeled as off road or
non-highway is typically very high in
sulfur content and will damage the
emission control system.
Non-highway fuel is not intended for
use in on-highway vehicles and
does not have the fuel properties
needed by the DPF-equipped
Duramax diesel.
In addition:
.
Use the correct engine oil.
.
Do not add gasoline to
diesel fuel.
.
Do not modify the induction or
exhaust systems.
See Fuel for Diesel Engines on
page 9-21 and Engine Oil on
page 10-6.
Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) is used
with diesel engines to reduce the
amount of regulated emissions
produced. The DEF system must be
maintained for the vehicle to run
properly.
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.
