A MESSAGE FROM DAIMLERCHRYSLER
CORPORATION
DaimlerChrysler Corporation and Cumminstwelcome

well over half of these trucks. Now this same technology
and proven performance is yours in your truck equipped
with the Cumminst, turbocharged, charge air cooled,
diesel engine.
Your diesel truck will sound, feel, drive, and operate
differently from a gasoline-powered truck. It is important
that you read and understand this manual. You may find
that some of the starting, operating, and maintenance
procedures are different. However, they are simple to
