Starting and Operating Your
Vehicle

New Vehicle Break-In

Notice: Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
•
Let your engine warm up before you operate
your vehicle under load.
•
Keep your speed at 55 mph (88 km/h) or less for
the first 500 miles (805 km).
•
Do not drive at any one speed — fast or
slow — for the first 500 miles (805 km).
Do not make full-throttle starts.
•
Avoid making hard stops for the first 200 miles
(322 km) or so. During this time your new
brake linings are not yet broken in. Hard stops
with new linings can mean premature wear
and earlier replacement. Follow this breaking-in
guideline every time you get new brake
linings.
•
Use the lowest gear you can when you start a
loaded vehicle in motion and when going up
hills to avoid overloading the engine.
2-6
•
Check and adjust engine and transmission fluid
levels often and be sure tires are properly
inflated for the load you are carrying.
