Chevrolet Sonic Repair Manual: New Vehicle Break-In

Notice:

The vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines:

• Do not drive at any one constant speed, fast or slow, for the first 805 km (500 mi). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle.
• Avoid making hard stops for the first 322 km (200 mi) 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.

Following break-in, engine speed and load can be gradually increased.
