Just came on. True?"...it means oil change needs to be done and resetting is the trip mileage odometer a nd b turns the lite off?

I did this as in the book and no reset the lite is still on. Also the red triangle will go out when the maintenance reqd lite is reset? WARM

 

DO you have NAV? I just went to the menu screen and reset the Maintenance reminder.

 

Nope Manual says to reset the a and b odometer rest button for 3 seconds and hold the reset button down as you turn on the ignition.
