Starting and Stopping the Engine
3. The accelerator pedal, service brake pedal, and clutch pedal
(if equipped) must not be pressed.
4. The parking brake must remain set.
On average (depending on filter level and other factors), the process
takes 20–30 minutes to complete. The DPF lamp turns off when the
process is complete. Repeat Steps 1–5, if parked regeneration is
interrupted.
To Discontinue Parked Regeneration
Press any of the floor pedals to discontinue parked regeneration.
Maintenance and Service
The DPF is designed to retain a relatively large amount of residual ash
and provide many miles and hours of maintenance-free operation. At
some point, generally beyond 150000 miles (240000 kilometers) or
5000 hours of operation (whichever comes first), the DPF requires
professional cleaning to remove the accumulated ash.
The exact number of miles or hours of operation varies greatly
depending upon vehicle and engine loading and operating conditions, ash
content of the engine oil, and quality of the diesel fuel used in your
truck. Adhering to your engine manufacturer's recommended oil and fuel
specifications maximizes the miles and hours of operation before a DPF
professional cleaning is required. See your engine manufacturer's owner's
manual for more details regarding recommended maintenance and
service of your DPF.
Exhaust Outlet Assembly
WARNING: The normal operating temperature of the exhaust
system is very high. Never work around or attempt to repair any
part of the exhaust system until it has cooled. Failure to follow these
instructions may result in serious personal injury.
Note: Do not modify or remove this device. Modification of the system
or additions of aftermarket devices can reduce the effectiveness of the
system, as well as cause damage to the exhaust system or engine. Any
modifications may also invalidate the vehicle and/or engine warranties.
See your warranty information.
Note: Blocked or plugged holes or modification to, or removal of, the
outlet assembly could result in elevated exhaust temperatures which may
result in vehicle or property damage or personal injury.
