New vehicle break-in driving - the first 1,000 miles (1,600 km)
The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km):
Do not race the engine. And do not
allow engine speed to exceed 4,000 rpm
except in an emergency
