It should come on before *100 miles. (this is just the wrench, no #, you will do initial break in service / oil change)
Reset it..
It should pop up wrench #1 around the next 600 miles after reset. This is not an oil change, just general service
Reset it...
It should pop up wrench #2 around the next 600 miles after wrench 1 reset. This is for an oil change and other services.
Reset again.
The wrench is not tied to the actual ODO. It is tied to the remaining maintenance ODO countdown menu.
So if you reset at say.. .350 miles. Then it will not pop up again until 950 miles.
Every time you reset it, it starts back over at 600 miles and begins to count down.
It will alternate between wrench 1 and wrench 2 after every reset.
You can check this by pushing the button to get to the maintenance screen.
