106 Starting and Stopping the Engine
Note: Do not increase engine speed until the oil pressure gauge
indicates normal pressure. This should be indicated on the gauge within
15 seconds after starting.
Note: Idle the engine for three to five minutes before operating with a
full load.
Note: Try to limit engine idle to 10 minutes. Excessive idling reduces
fuel economy.
Vehicles with a Manual Transmission
Note: Do not touch the accelerator pedal.
1. Fully press the clutch pedal.
2. Start the engine.
Vehicles with an Automatic Transmission
Note: Do not touch the accelerator pedal.
1. Select position N, or P (if equipped with a Park position).
2. Fully press the brake pedal.
3. Start the engine.
Starting the Engine with the Vehicle on a Steep Grade
When starting a diesel engine when the loaded vehicle is on a grade, the
engine RPM starts to fall slightly when the clutch is engaged. Do not
disengage the clutch and try to increase engine RPM as this may damage
driveline components. The engine recovers as the vehicle begins moving.
DIESEL PARTICULATE FILTER (DPF)
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. Use special care when
working around the diesel particulate filter. The DPF heats up to a high
temperature after only a short period of engine operation, and can
remain hot even after the engine is turned off. Failure to follow these
instructions may result in serious personal injury.
Your vehicle is equipped with a diesel particulate filter (DPF), as part of
the after-treatment exhaust system, to trap soot and other large particles
produced by the engine combustion process. The soot that accumulates
in the filter must be periodically reduced to ash to prevent excessive
exhaust restriction. The soot reduction process, also known as "filter
regeneration," is generally performed automatically by your engine and
after-treatment system.
