ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater cord is routed behind the front
bumper and accessible through the right hole of the air
dam.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
It includes a removable cap that is secured by a teth-
ered strap. It also has a c-clip that is used for storage
when not in use for the Winter months. During Winter
months, remove the heater cord wiring assembly from
itself on the c-clip.
NOTE:
The block heater will require 110 Volt AC and 6.5 Amps
to activate the heater element.
Block Heater Usage
For ambient temperatures below 0°F (-18°C), engine
block heater usage is recommended.
For ambient temperatures below –20°F (-29°C),
engine block heater usage is required.
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
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. For the recom-
mended viscosity and quality grades
page 338.
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. Please check your oil level
with the engine oil indicator often during the break in
period. Add oil as required.
ENGINE BREAK-IN RECOMMENDATIONS —
DIESEL ENGINE
The Cummins® Turbo Diesel engine does not require a
break-in period due to its construction. Normal opera-
tion is allowed, providing the following recommenda-
tions 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
page 155.
For additional vehicle break-in requirements, refer to
“Trailer Towing” in “Starting And Operating” of the Own-
er’s Manual.
Because of the construction of the Cummins® Turbo
Diesel engine, engine run-in is enhanced by loaded
operating conditions which allow the engine parts to
achieve final finish and fit during the first 6,000 miles
(10,000 km).
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave the trans-
mission in PARK.
The foot operated parking brake is located below the
lower left corner of the instrument panel. To apply the
parking brake, firmly push the parking brake pedal fully.
To release the parking brake, pull the parking brake
release handle.
