Trip odometers A & B are easily reset by pressing in on the brightness adjustment control at the lower right corner of the speedometer window. There's just no reset for the main odometer.
Also be warned, resetting the maintenance minder does NOT mean you can drive another 5000 miles on the old dirty oil. Get the maintenance done and let the mechanic reset the minder warning. Don't reset it yourself or you'll likely forget to go get the maintenance done and just burn up your engine by neglect.

Even if the oil still appears clear, the detergents break down after 3000-5000 miles. You can't see that, but they are equally critical to the engine. It's foolish to save $50 by skipping every other oil change and shorten the life of your $10,000 engine from 200,000 miles to 100,000 miles. Oil is cheaper to change.
