WARNING! Never allow an Automatic regen-
eration to automatically start while inside a
building such as a service bay, shop or build-
ing of any kind. Any time you are parking
your vehicle inside a building or enclosure,
ALWAYS press the Regeneration (STOP)
switch prior to entering the building. Failure
to do so could ignite an explosion which
could result in death or serious injury to you
and/or bystanders.
WARNING! Never initiate a Parked Regener-
ation in a closed building or enclosure.
Always park your vehicle outside. Failure to
do so could ignite an explosion which could
result in death or serious injury to you and/or
bystanders.
CAUTION: Do not leave the switch in the
STOP position unless you need to cancel or
stop regeneration.
Leaving the switch in
the STOP position for extended periods of
time will result in increased soot levels in
the DPF.
Stopping The Engine
Before Stopping The Engine
A hot engine stores a great amount of heat. And it doesn’t
cool down immediately after you shut it off. Always cool
your engine down before shutting it off. You will greatly
increase its service life.
Idle the engine at 1000 RPM for five minutes. Then low
idle for thirty seconds before shutdown. This will allow cir-
culating coolant and lubricating oil to carry away heat from
the cylinder head, valves, pistons, cylinder liners, turbo-
charger, and bearings. This way you can prevent serious
engine damage that may result from uneven cooling.
Turbochargers
This cooling-down practice is especially important on a
turbocharged engine. The turbocharger contains bearings
and seals that are subjected to hot exhaust gases. While
the engine is operating, heat is carried away by circulating
oil. If you stop the engine suddenly after a hard run, the
temperature of the turbocharger could rise as much as
