The performance and long life of your vehicle are dependent on how you handle and care for your vehicle while it is new. Follow these instructions during the first 1,000 miles (1,600km):

-do not race the engine, and do not allow engine speed to exceed 4,000rpm except in an emergency.
-do not drive at one constant engine or vehicle speed for a long time, either fast or slow.
-avoid starting suddenly and rapid acceleration, except in an emergency.
-avoid hard braking, except in an emergency.

like i said, it takes patience and discipline.

IMO mas maganda sigurong mag-break in sa highway kasi nako-control mo yung engine or vehicle speed, whereas sa city, pag na-stuck ka sa traffic, you'd be in idle forever.
Tama 'tong nasa manual ng Forester. You should check with your car's manual kung gano katagal break-in period nila. Dati standard among Japanese vehicles na yung 1st 1000 kms ang break-in pero sa iba like here with the Forester 1500 or 1600 kms ang break-in.
It doesn't matter whether city or highway driving ang gawin mo basta the key is not to stress the engine too much at this point. Ako pag nagbebreak-in ng auto, I don't bring it to Baguio or other places na paakyat para di mapwersa yung makina. Napaisip tuloy ako, pano kung taga-Baguio ka tapos bumili ka ng bagong auto?
