Starting Your Diesel Engine
If you have a Caterpillar diesel engine, also refer to your
Caterpillar
R
Diesel Engine Operation & Maintenance
Manual for starting procedure.
To make starting easier in cold weather (below 32
_
F or
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.
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.
Restarting the Diesel Engine While Moving
(Automatic Transmission)
If you have to restart the engine while the vehicle is
moving, you’ll first have to shift the automatic
transmission to NEUTRAL (N). This safety feature
prevents starting the engine when the transmission is in
a drive gear.
Stopping the Diesel Engine
If you have a Caterpillar diesel engine, see your
Caterpillar
R
Diesel Engine Operation &
Maintenance Manual.
1. Set the parking brake and shift to NEUTRAL (N)
or PARK (P).
2. Turn the ignition key to OFF.
If your vehicle has a two
-speed axle, see “Rear Axle,
Two
-Speed Electric Shift Control” or “Rear Axle,
Two
-Speed Airshift Control” in the Index.
