Fitment & sizes
Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.
From the factory this vehicle uses a BCI 34 · 600 CCA battery, OE oil filter 12731175. Note the factory cabin air filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified
Normal service, condensed from the factory interval matrix.
Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.
Every 25,000 mi
