with RPO DF5 or TQ5 (Intellibeam®) Inside Rearview Mirror



Some dealers/customers may notice that the outside temperature and compass are not displayed in the inside rearview mirror. The mirrors are usually turned on when the vehicles leave the assembly plant, but there may be situations when the mirrors may be turned off by the transport company, dealer personnel and/or the customer.

If you experience a vehicle that has an inoperative compass and temperature display, make sure that the function is turned on in the mirror. Briefly press the on/off button on the left side of the mirror (RPO DF5) to turn the display on.

The green LED that is on the left side of the mirror is for the automatic dimming function. There has been some confusion in which a customer sees the green LED and thinks that this automatically means the compass and the temperature display should be illuminated. So the customer may not try to turn the function on.

If the vehicle is equipped with the Intellibeam® (RPO TQ5) mirror, press and hold the auto headlamp button on the left side of the mirror for 3-5 seconds.

The Warranty Parts Center (WPC) has found that several of the mirrors were returned with the function turned off and there were no problems found with the mirror.
