ECOMMENDATIONS
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. You should avoid wide-open
throttle acceleration in low gear as it can be
detrimental.
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
recommended viscosity and quality grades
page 79.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may result.

This breaking 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 below 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 gears).
●
Avoid aggressive braking.
●
Drive with the engine speed below 5,000
RPM.

ECOMMENDATIONS
●
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 (paddles or gear shift) at higher
RPMs 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.
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.
