There's no oil sensor, so the OBC wouldn't know that you'd put in fresh oil.

I think you get a free oil change if it's been one year since your last one, regardless of how many miles you've accumulated.

 

That's what my SA told me, too.

 

The car calculates the 'miles until service' based on gas utilization. If you track the car hard and get a low MPG, it may indicate that you may need service before the first 10,000 miles. If you drive it very gently and get higher MPG, you may not need service for 15k+ miles. It does not detect that you replaced the oil yourself by sampling the oil. If you reset the service indicator (it can be done... search NAM) while still in the free maintenance period, you could cheat yourself out of a free oil change and service at the dealership.

I changed my oil after 2,000 or so and again every 5,000 miles. I drive my car fairly hard and do the occasional DE or Auto-X, so I think that it's worth it.

 

How about topping of fluid like brake, coolant, aircon filter, wiper blades etc?s it part of free maintenance schedule??

 

I always brought it in on scheduled service intervals and had service dept. do all recommended work for warrenty maintenance. It was always covered under warrenty. No charges to me until after 36,000 miles.
