How do i reset maintanence required light?

i already tried holding the odometer button and putting the key on "on", any alternative ways? any help is appreciated thanks

 

Is the odo. reading displayed before you turn the truck off?

 

yes its not on a or b trip i checked that

 

Set it to trip A , turn the key to the off, hold down button then turn key to ACC
It should show 000000..if that doesn't work, repeat it on trip B

 

thanks for the help , trip a did the trick!
