Share this information with you customers as needed.
During the first 1000 miles (1610 km):
1. Avoid long periods of engine idling.
2. Wait until the engine has reached operating temperature before driving
enthusiastically.
3. Check the engine oil level at each fuel fill since a new engine may consume some oil
during the first few thousand miles (this is normal and not a sign of an engine problem).
4. Keep the vehicle speed below 70 mph (113 km/h).
5. Do not make any full throttle starts or full throttle accelerations.
6. Avoid driving at a constant engine rpm for long periods as follows:
. First 200 miles interval (322 km), light throttle run-ups shifting at a maximum of 2500
rpm.
. In addition, it is suggested to change the engine oil within the first 200 miles of engine
break-in.
. Second 200 miles interval (322 km), light throttle run-ups shifting at a maximum of
3500 rpm.
. Third 200 miles interval (322 km), light throttle run-ups shifting at a maximum of
4000 rpm.
. Fourth 200 miles interval (322 km), light throttle run-ups shifting at a maximum of
4500 rpm.
. Fifth 200 miles interval (322 km), light throttle run-ups shifting at a maximum of 5000
rpm.
