The First 1000 Miles (1609 km.)
It is desirable to limit driving speeds during the first 1000 miles (1609 km.) of operation in order that the closely fitted parts of the engine and chassis may have an opportunity to “wear in” smoothly.
For the first 500 miles (805 km.) it is recommended that you do not drive your car at speeds in excess of 50 miles (80,5 km.) per hour. For the second 500 miles (805 km.) it is recommended that you do not drive your car at speeds in excess of 60 miles (96,6 km.) per hour.
While it is always better to let your engine warm up at lower speeds, you should, by all means, follow such a practice during the first 1000 miles (1609 km.) of operation.
Further, it is well to avoid continuous high speed driving during the first 1000 miles (1609 km.) even though the engine has been warmed up.
