The automatic day-night mirror uses two photocell sensors in order to determine light conditions in the front and the back of the vehicle. At night, as the glare of the headlamps from behind increases, the mirror gradually becomes darker in order to absorb the glare. In the daytime, the mirror is in a clear state. With the ignition switch in the ON position, battery positive voltage is applied to the automatic day/night mirror connector cavity. When the automatic day/night mirror switch is placed in the AUTO position, battery positive voltage is applied to the automatic day/night mirror circuit. Battery positive voltage is supplied at all times to the REVERSE relay coil through the rear fuse block. Battery positive voltage is supplied at all times to the REVERSE relay switch through the PRK/REV fuse through the rear fuse block. The Powertrain Control Module (PCM) sends a class 2 message to the Rear Integration Module (RIM) indicating that the gear selector lever is in the REVERSE position. The ignition switch is in the ON position. When these conditions occur, the RIM energizes the REVERSE relay. This supplies battery positive voltage to the inside rearview mirror. The mirror will gradually change to a clear state as a result of the reverse input.

The inside rearview mirror also controls the reflectiveness of the left outside power mirror. The left outside power mirror darkens or clears along with the inside rearview mirror.

The electronic compass includes a fluxgate magnetic field sensor and a microprocessor. The microprocessor receives inputs from the sensor, processes the inputs, and provides outputs to the compass display. The compass display then indicates the vehicle heading relative to the Earth's magnetic fields.
