All I can find in my manual is the schedule for the V8. What mileage should I change my plugs at? Its a 2010 SE. Thanks!

Looks like 102,000 Miles or 102 Months (along with the timing belt). Found on page 431 of the manual.

Didn't realize the 3.5 had a belt, figured it was a chain. 102k is a bit far to expect a timing belt to last IMO. Now it's got me wondering if it's a free-wheeling or an interference motor. :think:
