My maintenance light (wrench symbol) on the dash lit up today. I checked the maintenance guidance on the nav system and there is no service interval low enough to trigger it. I just had the oil changed last week and my tire rotation is at 830 miles (and it shouldn't come on until 250 miles). Any idea why else it would come on. I found no help from the manual on why it would illuminate other than to remind of an oil or tire service. And unfortunately this doesn't produce a fault code so I can't figure it out that way either...hmmm...
