GMC T-Series 2007 User Manual

The DPF will regenerate (self-clean) itself as part
of normal operation. During regeneration, the
green DPF indicator is lit and you will notice a
difference in engine noise and engine speed,
but this is normal. The Engine Control Module
(ECM) controls this function based on several
factors including the amount of fuel consumed,
hours of engine operation and miles driven.
Notice: Use of diesel fuel other than Ultra
Low Sulfur Diesel (15 ppm sulfur maximum)
or engine oil other than low ash CJ-4 oil
will cause permanent damage to the DPF
and related components. This damage would
not be covered by your warranty.
Your DPF equipped vehicle has specific fuel
and engine oil requirements. See What Fuel to
Use on page 195 and Engine Oil on page 206 to
make sure you use the required fuel and
engine oil.
{CAUTION:
During DPF regeneration, the exhaust
system and exhaust gases are very hot.
Things that burn could touch hot exhaust
parts under your vehicle and ignite. You
or others could be burned. Do not park
near or over papers, leaves, dry grass,
or other things that can burn.
When the yellow DPF indicator comes on, the
filter is dirty and DPF regeneration is necessary.
When driving continues without regeneration,
the DPF indicator will change from yellow to
red. Continuing to drive the vehicle with the
red indicator can cause filter damage.
