CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and
not interpreted as a problem.
Diesel Engine
The Cummins turbocharged diesel engine does not re-
quire a break-in period due to its construction. Normal
operation is allowed, providing the following recommen-
dations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged
periods. •
Use the appropriate transmission gear to prevent
engine lugging.
•
Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carry-
ing or towing significant weight.
NOTE: Light duty operation such as light trailer towing
or no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
For additional vehicle break-in requirements, refer to
“Trailer Towing” in “Starting and Operating” of the
Owner ’s Manual.
Because of the construction of the Cummins turbocharged
diesel engine, engine run-in is enhanced by loaded oper-
ating conditions which allow the engine parts to achieve
final finish and fit during the first 6,000 miles (10 000 km).

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 113
Page 235 of 669

1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Voltmeter •When the engine is running, the gauge indicates the
electrical system voltage. The pointer should stay
within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced. NOTE:
The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize.
3. Oil Pressure Gauge
•The pointer should always indicate some oil pres-
sure when the engine is running. A continuous high
or low reading under normal driving conditions may
indicate a lubrication system malfunction. Immedi-
ate service should be obtained from an authorized
dealer.
4. Speedometer •Indicates vehicle speed.

Oil Temperature Warning Light
Red TelltaleLight What It Means
Oil Temperature Warning Light
This telltale indicates engine oil temperature is high. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible.

Transmission Temperature Indicator Light
Red TelltaleLight What It Means
Transmission Temperature Indicator Light
This light indicates that the transmission fluid temperature is running hot. This may occur with
severe usage, such as trailer towing. If this light turns on, safely pull over and stop them ve-
hicle. Then, shift the transmission into NEUTRAL and run the engine at idle or faster until the
light turns off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.
