OPERATING YOUR VEHICLE

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
detrimental 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 recommended viscosity
and quality grades, refer to "Maintaining Your Vehicle."
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 an engine problem or malfunction.
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or damage may
result.
Engine Break-In Recommendation — SRT Version
A long break-in period is not required for the drivetrain (engine, transmission, and
rear axle) in your new vehicle.
Drive moderately during the first 500 miles (800 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 is a high performance synthetic lubricant, the transmission fluid, and
axle lubricant installed at the factory is 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 recommended viscosity
and quality grades, refer to "Maintaining Your Vehicle".
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.
