The process of breaking in a vehicle means driving it so that parts can wear into each other. Usually, people think the engine is the only part that needs any break in period, but transmissions and drive axles also can benefit from a break in.

Here are some tips for breaking in a new car:
- Avoid heavy loads on the drivetrain. Full throttle starts, towing trailers, and loading the vehicle with heavy loads place extra force on all moving parts in the drivetrain.
- When starting a new vehicle, engines should not be idled for long periods of time. Oil pressure is lower at idle speed and parts that depend upon splash lubrication may not receive enough oil to prevent high spots from pushing through. Full throttle operation should also be avoided. It places heavy loads on components and high spots can score other components, accelerating the wear. This doesn't mean you need to baby the vehicle.
- Drive the vehicle as if you were trying to achieve good fuel economy. Light to medium throttle acceleration is preferred, and keep the engine rpm's in the bottom half of the rpm range. Occasional three-quarter throttle acceleration is fine, as the increased gas pressure in the combustion chamber helps the rings to seal.
- Avoid "lugging" the engine. Driving in too high a gear at low speeds makes the engine work harder. It is better to have it running a little faster with less throttle than too low an rpm with more throttle. Modern engines don't need to be driven at slow speeds. Keep up with traffic and drive the speed limit. I wouldn't recommend towing a trailer with a brand new vehicle, but it is done sometimes and the vehicles seem to last well.
