car is 2008 highlander and oil change & filter done at 4k miles, now at 5k miles
can't turn off the MAINT REQD light on dash
nope
tried this also
I'm not familiar with the Highlander, but is it possible that this light is turned on by the ECU for a fault condition in addition to the odometer trigger?
You might want to have the OBD codes read.
no, separate indicator light for ECU faults, this one is maintenance reminder only
Friend had this problem with his new Camry and dealer's shop gave him procedure. Since I usually change my own oil, I would consider this a PITA.
