ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and permits
quicker starts in cold weather. Connect the heater cord to a
ground-fault interrupter protected 110–115 Volt AC electri-
cal outlet with a grounded, three-wire extension cord.
Its use is recommended for environments that routinely fall
below -10°F (-23°C). It should be used when the vehicle has
not been running for long periods of time and should be
plugged in two hours prior to start. Its use is required for
cold starts with temperatures under -20°F (-28°C).
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
WARNING!
Remember to disconnect the cord before driving. Dam-
age to the 110–115 Volt electrical cord could cause elec-
trocution.
NOTE: The block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
ENGINE BREAK-IN RECOMMENDATIONS — 3.0L
DIESEL
The diesel engine does not require a break-in period due to
its construction. Normal operation is allowed, providing
the following recommendations 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 carrying
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.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. The recommended
