Toyota Yaris

I like to maintain my 2007 Toyota Yaris 4DR sedan. Here are some notes I’ve gathered:

How to reset the maintenance required light

  • Make sure the trip meter is on Trip A.
  • With the key in the off position, hold down the trip reset button. Note: Your trip meters will not be reset.
  • Turn the key to the ”on” position, but do not start the car.
  • The trip meter will display flashing dashes. Hold the trip meter while these dashes “count down”. When the dashes are gone, the ”MAINT REQD” light will turn off.

Changing the spark plugs

The spark plugs should be tightened to 13 ft lbs.


The lug nuts should be tightened to 76 ft lbs.

The tires are P185/60R15.

Serpentine Belt

The belt should be tightened to 102-103 Ft. Lbs. as measured from the bottom, between the crank and the air conditioner. This is easily done with a Gates 91132 belt tension tester.

Alternatively, the belt should be tightened to 0.41-0.45 in. of deflection when applying a force of 22 Ft. Lbs. from the top, between the crank and the alternator.
