Never Shut Down the Engine While
Driving
Warning
Do not move the engine control
switch away from the ON position
while the vehicle is being driven.
If the engine is shut down while the
vehicle is moving, the brakes will not
work properly. The engine could also
be damaged.
Shutting down the engine while
driving would be extremely dangerous
because the power steering would
stop working, making the steering
wheel extremely hard to turn.
Shutting down the engine while
driving would be extremely dangerous
because the warning lights, indicator
lights and other electrical circuitry
would completely stop working.
Placing the engine control switch in
the LOCK position while driving
would be extremely dangerous
because the key could come out,
causing the steering wheel to lock so
that you could not turn it.
Warning (Continued)
You and others could be seriously
injured.
Avoid Unnecessary Idling of the Engine
If the 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.
Driving at Night
Nighttime driving is more dangerous than
daytime driving because the field of view is
narrower. Keep your speed down, and
maintain an ample headway distance.

Driving and Operating
When the Silencer and Exhaust Pipe
are Hot
Warning
When the engine is running and
immediately after vehicle operation, the
DPF, silencer, and exhaust pipe are
extremely hot. Be careful not to
inadvertently touch them when working
near them (for example, tilting the cab or
operating an attachment). You and others
could be seriously injured.
Recommendations for Driving in Hot
Regions
The engine is more likely to overheat in an
environment where the ambient
temperature is high. To prevent the engine
from overheating, pay attention to the
following points:
If the engine does not contain the
appropriate concentration of engine
coolant, overheating is likely to occur.
Refer to Engine Coolant 0 203.
Do not put well water, river water,
or other hard water in the engine cooling
system. It would hasten the formation of
rust and scale.
