OCR precautions and safe exhaust position
WARNING: Failure to comply with the following instructions for
operator commanded regeneration (OCR) may result in fire,
serious injury, death and/or property damage.
Before you start OCR, observe/do the following:
• Place the vehicle in P (Park) with the parking brake set on stable,
level ground.
• The vehicle must not be parked in a structure.
• The vehicle must be away from any obstructions within 10 - 15 feet of
vehicle,
• and must be away from materials that can easily combust or melt such
as: paper, leaves, petroleum products, fuels, plastics and other dry
organic material, such as grass.
• Make sure there is a minimum of 1/8 tank of fuel.
• Make sure all fluids are at proper levels.
Make sure that the louvers (holes) located at the tip of the exhaust are
also clear of any obstructions as they are used to introduce fresh air into
the tailpipe to cool the exhaust gas as it leaves. See Exhaust under the
Cleaning chapter for more information.
