STARTING AND OPERATING 251
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,
three-wire extension cord.
Gasoline Engine Only
The engine block heater cord is routed through the grille by
the right front tow hook.
It includes a removable cap that is secured by a tethered
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.
The engine block heater must be plugged in at least one hour
to have an adequate warming effect on the engine.
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 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, refer to “Fluids And
Lubricants” in “Technical Specifications”.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.
