Like many other Toyota vehicles, the process to reset the oil change (Maintenance Required) light on the Toyota Highlander is much the same.
A common problem with Toyota vehicles is the owner may find the “VSC OFF” and “Check Engine” lights illuminated simultaneously. VSC stands for “Vehicle Stability Control“. It is likely that “Traction Control” will not work while this light is illuminated. On some vehicles, the “skidding vehicle” or “TRAC OFF” light may also be lit.
