The -700 means you're 700 miles overdue for an oil change...unless the service tech forgot to reset it when he did the oil change.
The number doesn't go up by 100 every day...but if you drive it 98 miles every day it will.
If you search the site you can find the service manual...in it is the procedure for resetting the FSS mileage. I'd just send it over to ya but I'm on my work computer!
BTW...I feel your pain...6'4" 198#!
