When the dealer services your car, they are supposed to reset the oil or service interval warning light that comes on in place of your trip odometer when you start your car. To reset it yourself to a fixed interval (you need to hook up to a computer for a variable interval), follow these instructions:
1. Insert your key into the ignition.
The key to this is to perform step 4 before the "Service!" message disappears and changes to the usual message about holding the brake down while shifting out of Park.
