Boxer engines have specific oil consumption patterns — check oil monthly. CVT service every 30K is critical; skipping shortens life dramatically. AWD requires matched tire wear.

"Severe service" conditions (heavy towing, extreme temps, city stop-and-go) typically halve these intervals. Always consult your vehicle's owner's manual for the authoritative schedule.
