After-Treatment System Description
NOTE: The emission warning lamps and emission
switch functions described below super sede those
listed in the Engine manufacturer's Operator and
Maintenance manual. For additional Emissions
Aftertreatment information specific to your engine,
see the Engine manufacturer's Operation and
Maintenance Manual supplied in your vehicle. All
other lamp and switch functionality described in
the manual are still valid.
In order to meet 2007 EPA engine emission requirements ,
vehicles will have an exhaust After-Treatment System
(ATS) which includes a Diesel Par ticulate Filter (DPF),
Regeneration Switch and warning lights. The DPF will
trap soot from the engine exhaust gases. The ATS will
periodically clean the DPF.
The Regeneration Switch is mounted on the dash and can
override the ATS. Various situations may require the
operator to use the functions of this switch. Refer to
“Parked Re gen eration” on page 7 and “Stop an Automatic
or Parked Regeneration” on page 9 for more information.
ATS specific warn ing lights and indicator symbols appear
on the dash panel, abov e the air cond itioning con trols an d
radio.

EMISSIONS FUNCTIONALITY / NOTIFICATION INFORMATION
Functionality / Notification
Information
The ATS will clean the DPF by using hot exhaust gases
normally generated by the engine. This typically occurs
during highway operation. This is referred to as a "Passive" Regeneration and is transparent to the operation of
the vehicle.
Occasionally, the exhaust gases are too cool for passive
regeneration. When this occurs, the ATS will clean the
DPF by increasing the exhaust temperature. This is
referred to as an "Automatic" Regeneration and is also
transparent to the operation of vehicle. An Automatic
Regeneration ev ent typically lasts 30 minutes . During and
shortly after the event, the exhaust gases from the DPF
may reach temperatures in e xcess of 650 C (1200 F). See
the information in the table below on probable causes and
recommended actions related to the warning lights and
indicator symbols of the ATS.
The ATS may not be able to clean the DPF when the vehi cle is driven at extended low speeds or with frequent start
and stops. In such cases, warning lights and indicator
symbols will alert the operator to take action. The operator
should be aware of whether the lights are on alone or in
combination with others. The following table will describe
each warning light(s) and what actions are needed from
the operator.
