WARNING!
•
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the con-
verter and vehicle.
•
If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a
booster battery or the battery in another vehicle.
This type of start can be dangerous if done improp-
erly
page 188.
CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
COLD WEATHER OPERATION
(BELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures, use
of an externally powered electric engine block heater
(available from an authorized dealer) is recommended.
AFTER STARTING
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
ENGINE BREAK-IN RECOMMENDATIONS
— 3.6L & 5.7L
A long break-in period is not required for the drivetrain
(engine, transmission, clutch, and rear axle) in your new
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.
However, wide-open throttle acceleration in low gear
can be detrimental and should be avoided.
The engine oil, transmission fluid, and axle lubricant
installed at the factory are high-quality and energy-
conserving. Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions
under which vehicle operations will occur. For the rec-
ommended viscosity and quality grades
page 238.
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 an indication of difficulty. Please check
your oil level with the engine oil indicator often during
the break in period. Add oil as required.
ENGINE BREAK-IN RECOMMENDATIONS
—6.4L
The following tips will be helpful in obtaining optimum
performance and maximum durability for your new
vehicle.
Despite modern technology and World Class manufac-
turing methods, the moving parts of the vehicle must
still wear in with each other. This wearing in occurs
mainly during the first 500 miles (805 km) and contin-
ues through the first oil change interval.
It is recommended for the operator to observe the fol-
lowing driving behaviors during the new vehicle break-in
period:
0 to 100 miles (0 to 161 km):
•
Do not allow the engine to operate at idle for an
extended period of time.
•
Press the accelerator pedal slowly and not more
than halfway to avoid rapid acceleration.
•
Avoid aggressive braking.
•
Drive with the engine speed less than 3,500 RPM.
•
Maintain vehicle speed below 55 mph (88 km/h)
and observe local speed limits.
100 to 300 miles (161 to 483 km):
•
Press the accelerator pedal slowly and not more
than halfway to avoid rapid acceleration in lower
gears (FIRST to THIRD gear).
•
Avoid aggressive braking.
•
Drive with the engine speed less than 5,000 RPM.
•
Maintain vehicle speed below 70 mph (112 km/h)
and observe local speed limits.
