STARTING AND OPERATING
ENGINE BREAK-IN RECOMMENDATIONS —
6.2L AND 6.4L
The following tips will be helpful in obtaining
optimum performance and maximum durability
for your new vehicle.
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
continues through the first oil change interval.
It is recommended for the operator to observe
the following 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 accelera-
tion in lower gears (FIRST to THIRD gears).
 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.
300 to 500 miles (483 to 805 km):
 Exercise the full engine RPM range, shifting
manually at higher RPM when possible.
 Do not perform sustained operation with the
accelerator pedal at wide open throttle.
 Maintain vehicle speed below 85 mph
(136 km/h) and observe local speed limits.
For the first 1,500 miles (2,414 km):
 Do not participate in track events, sport
driving schools, or similar activities during
the first 1,500 miles (2,414 km).
NOTE:
Check engine oil with every refueling and add if
necessary. Oil and fuel consumption may be
higher through the first oil change interval.
Running the engine with an oil level below the
add mark can cause severe engine damage.
MANUAL TRANSMISSION — IF EQUIPPED
RECOMMENDED SHIFT SPEEDS
To utilize your manual transmission efficiently
for fuel economy, it should be upshifted as
listed in recommended shift speed chart.
