How to Turn On the Rearview Mirror Heating in a Grand Cherokee?
2 Answers
First, start the car and begin driving smoothly. After pressing the button, a small yellow light will illuminate, indicating that both the rearview mirror and rear window heating are activated. The heating will automatically turn off after approximately 10-15 minutes. An electric heating element is installed inside the lenses of both side rearview mirrors. When the rearview mirror heating function is turned on, the heating element will quickly warm up to a set temperature. The rearview mirror heating function refers to the ability of the rearview mirrors to be heated via electric wires embedded behind the lenses when driving in rainy, snowy, or foggy weather conditions.
As a long-time owner of a Grand Cherokee, I'm very familiar with the operation of the rearview mirror heating function, which is especially useful when driving in winter. Typically, after starting the vehicle, you just need to locate a square button on the dashboard or center console with small wavy lines or labeled 'REAR'. Pressing this button simultaneously activates the heating function for both the rearview mirrors and the rear window. The exact position is usually near the central air conditioning panel, closer to the driver's side. Once the button's indicator light turns on, it means the system is working. Wait a few minutes, and the fog or frost on the mirrors will gradually disappear. I prefer to turn it on before setting off to prevent obstructed vision. Remember, it's safer to operate after the engine is running; avoid pressing it when the engine is off to prevent excessive battery drain. If the button doesn't respond, it might be due to a blown fuse or system malfunction—check the manual or visit a repair shop. Overall, this feature is very convenient, especially on rainy, snowy days, or early mornings, ensuring clearer visibility and peace of mind. It's become a habit for me.
