314 STARTING AND OPERATING
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a stan-
dard 110-115 Volt AC electrical outlet with a grounded,
t
hree-wi
re extension cord.
The engine block heater must be plugged in at least one hour
t
o
have
an adequate warming effect on the engine.
The engine block heater cord is found under the hood
bundled
in front of the battery tray.
ENGINE BREAK-IN RECOMMENDATIONS
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 ini
tial 60 miles (100 km), speeds up to 50 or 55 mph (80 or
90 km/h) a
re desirable.
While cruising, brief full-throttle acceleration within the
l
imits
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-qua
lity energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur.
For the recommended viscosity and quality grades, refer to
“Fluids
And Lubricants” in “Technical Specifications”.
NOTE:
A new engine may consume some oil during its first few
thousan
d miles (kilometers) of operation. This should be
considered a normal part of the break-in and not interpreted
as a problem.
WARNING!
Remember to disconnect the engine block heater cord
before d
riving. Damage to the 110-115 Volt AC electrical
cord could cause electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engi
ne or damage may result.
