It tells you in the manual how to clear it, has to do with the yellow override button and turning the key on for 10 seconds, then off and pushing the button to bring up the wrench icon,if you don't have a manual I'msure someone can give a better explaination.
You can download the owners manual directly from Polaris. It should have the procedure for resetting the icon.
