My Fortuner is already at 4,900 kms. on the odometer and it is already 6 months old. When should I have it serviced? It should be every 5,000 kms or every 6 months, whichever comes first, right?

The unit was acquired in August 31 (2006), and it had its first 1,000 km. check-up sometime in mid-October.


Here's where I get confused:

When should I start counting for the six months? August 31, or mid-October?

Or if the the odometer/mileage comes first, should I start counting after the 1,000 kms? Or kasama na ba yung first 1,000 kms sa every 5,000 km check-up?
