Where is the Fista rearview mirror heating switch?
2 Answers
The Fista's rearview mirror heating button is located in the control area, with two knobs (AUTO and SYNC) on the left and right, each with a button underneath. The button below the right knob (SYNC) is the defogging symbol for the rear windshield, which is also the rearview mirror heating button. Its icon is a rectangle with three upward wavy lines inside. The rearview mirror heating function is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rainwater or fog, eliminating the need for the driver to frequently wipe the mirror manually, thereby reducing driving hazards. Methods to use the rearview mirror heating function: The rearview mirror heating function generally has two activation methods. One is combined with the electric rearview mirror adjustment function key, where simply rotating the knob activates it. The other is located on the air conditioning control panel, where pressing the heating button turns it on. There is no need to manually adjust the angle, as the driver's side has an adjustment button. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass will rapidly heat up to a fixed temperature within a few minutes, typically between 35-60 degrees. The heat will dissipate from the left and right rearview mirrors. Simultaneously, due to the temperature rise and evaporation, water droplets on the mirror surface will become smaller, and fog will gradually disappear, thereby heating the mirror and removing frost. If the rainfall is particularly heavy, its effect will diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the rearview mirror. These wires consume a significant amount of electricity. When using the rearview mirror heating function, ensure the car is in a running state. Avoid activating the function while the car is stationary to prevent draining the car battery, which could leave insufficient power to start the vehicle. Other methods for defogging the rearview mirror include: Opening windows for convection: Crack open the side windows slightly to allow air convection between the inside and outside of the car. This reduces the temperature difference, causing the fog to gradually disappear. Adjust the car's air conditioning to the appropriate setting to use the hot air blown out by the air conditioner for defogging.
I've been commuting with my Fiesta for two years, and the rearview mirror heating switch is located on the air conditioning panel, sharing a small rectangular icon with wavy lines with the defogging button on the center console. If you notice fogging on the rear window while driving, just press it, and the rearview mirrors will heat up simultaneously. Note that the manual states this function automatically turns off when the outside temperature exceeds 20 degrees to prevent overheating. During the rainy season, if the glass gets blurry, press it, and the water droplets on the mirror will disappear in about five minutes. However, avoid keeping it on continuously, as it may shorten the lifespan of the heating element. This design is quite clever, saving space for a separate button.
