Driving and Operating
3. Check that the battery warning light has
gone out. The light should go off and
stay off at normal idle speeds. If the
light does not go out or comes on
during normal operation, have the
charging system checked.
Warning
To reduce the chance of personal injury
and/or vehicle damage due to engine
overheating, never leave the engine idling
without an alert driver present. If the
engine should overheat, as indicated by
the engine coolant temperature gauge,
immediate action is required to correct
the condition. Continued operation of the
engine, even for a short time, may result
in a fire.
Do not engage the exhaust brake while
the engine is idling as this may cause
engine overheating. You and others could
be seriously injured.
Avoid Unnecessary Idling of the Diesel Engine
If the diesel engine idles too long, the
engine coolant temperature will fall below
the operating range. Low engine operating
temperature causes several conditions
that are harmful to engine operation
and life.
Incomplete combustion of fuel in an engine
that is not fully warmed-up causes crankcase
dilution and forms lacquer and gummy
deposits on valves, pistons, and rings. It also
causes rapid accumulation of sludge within
the engine.

Parking over Things That Burn

Warning
Exhaust parts and gases become very hot
when the DPF is being regenerated.
Parking over flammable items could allow
them to touch hot exhaust parts under
your vehicle and cause them to ignite. Do
not park over papers, leaves, grass or
other things that can burn. Make sure
there is not flammable material (for
example, grass, waste paper, oil or old
tires) on or near the DPF or exhaust
system. You and others could be
seriously injured.
Keep Flammable Material Away from the
Vehicle
The exhaust pipe is extremely hot
immediately after vehicle operation. Before
parking, make sure the area is free of
flammable material (for example, grass,
falling debris like leaves, waste paper, oil or
old tires). Take particular care when parking
in a garage.
Use caution concerning exhaust gases while
the engine is idling. For diesel vehicles, be
particularly careful when the power take-off
(PTO) is operating (if your vehicle is
equipped with a PTO) or the DPF is
regenerating while the engine is idling. See
Diesel Particulate Filter 0 145.
Warning
It is not recommended that this vehicle
be parked, idled or operated over
combustible materials such as grass or
leaves. They could touch the hot exhaust
system and start a fire. This is
particularly important if the exhaust
system has not been properly
maintained. Combustible materials could
catch fire from hot exhaust gases, soot,
