While your engine is idling before you turn it off, you
can make a list of any operational or handling concerns
to give to responsible maintenance personnel so they can
handle them right away.
Moisture will condense in a fuel tank that is almost
empty if the vehicle is not run for a while, even just
overnight under some conditions. So, it's always best to
refuel your vehicle at the end of each run.
Starting Your Diesel Engine
If you have a Caterpillar diesel engine, also refer to your
R
Caterpillar
Diesel Engine Operation & Maintenance
Manual for starting procedure.
To make starting easier in cold weather (below 32
_
0
C), the proper viscosity engine oil should be used. It's
also best to heat the engine oil first. You can do this by
using an engine coolant heater. A GM Automatic Ether
Injection System aids cold weather starting.

Motor Operation
If your vehicle has the optional heavy duty starter it
may, on rare occasions, not engage. This condition is
normal. If this happens, release the ignition key, and
reattempt to start the engine.

NOTICE:
Your diesel engine has an electric air intake
heater system which reduces white smoke and
helps start the engine in cold weather. Do not
spray starting fluid into the air intake where it
can contact the heater elements.
If you don't have the GM Automatic Ether
Injection System, don't use starting fluid or you
could damage your engine. If you have the GM
system, use only GM approved starting fluid that
_
has been tested to establish compatibility with the
F or
air inlet heater system.
NOTICE:
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See "Towing
Your Vehicle" in the Index.
