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 the 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 the 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.
• Check and adjust engine and transmission fluid
levels often and be sure tires are properly
inflated for the load you are carrying.
• When new, parking brake linings have not yet
been broken in. When linings are new, it is
possible that the vehicle could move while the
parking brake is applied. Before using the
parking brake on grades, follow the parking
brake burnish procedure. See Parking Brake
Burnish Procedure on page 2-43.
• If you have a Caterpillar

diesel engine, see the

®
Diesel Engine Operation and
Maintenance Manual.
