How to Turn on the Outside Air Temperature Sensor on a Nissan Xterra
- 1). Crank your engine, or turn your key to the "On" position (the Xterra's electronics must be turned on).
- 2). Examine your rear view mirror to find the compass and temperature power button. This button is located on the bottom-center part of the mirror.
- 3). Press and hold the button for about one second. Look in the upper-right corner of the mirror; the compass and outside temperature should be visible in the small display.
