What does 'setrear' mean on the car's air conditioner?

The 'set-rear' button found in a car's air conditioning system is the rear window defogger button. Here are methods to defog the rear windshield in winter: 1. Open windows for convection: Crack open the side windows slightly to allow air flow between inside and outside the car, reducing temperature differences and gradually eliminating fog; 2. Use the air conditioning system: Simply select the appropriate setting to direct the AC airflow for defogging; 3. Apply professional defogging spray: Spray the defogger onto the inner surface of the car window, then wipe it clean. This not only removes dirt but also forms a protective film to prevent moisture condensation and fog formation on the glass.
Hey buddy, see that 'setrear' button next to the steering wheel on the AC panel? That's the magic key for controlling rear AC. Super useful when driving a 7-seater - one press lets you independently adjust the temperature and airflow for the second row, so kids can sleep in the back without catching a chill. Last time I drove my mother-in-law, she felt cold and adjusted the temperature directly from the rear vents - my center display immediately showed 'Rear 23°C', way classier than yelling 'Mom, are you cold?'. This feature's basically standard now in domestic MPVs, even the Wuling Capricorn hides a touchscreen behind the armrest.
As a tech enthusiast, let me break it down for you: 'Set Rear' is essentially the interactive entry point for decoupling the front and rear air conditioning systems. When you trigger this touch-sensitive button, the central control system takes over the independent fan control for the rear. Taking the Li Auto L9 as an example, the front screen will then pop up a three-zone control interface, allowing you to individually set the airflow and temperature curves for the second/third rows. Some luxury cars take it even further, enabling synchronized control over rear seat ventilation and heating. However, it's important to note that many vehicles require the air conditioning to be in auto mode to activate this function key—otherwise, the backlight of the button remains off.
Moms should pay special attention to this button! Once when I took my child for vaccination, the mischievous kid kept tapping around in the rear child seat and suddenly the AC blasted cold air directly at him. Later I realized it was accidental activation of the "setrear" button on the center armrest. Newer models now feature anti-misoperation designs - for instance, the Trumpchi M8 requires a 3-second long press to switch control. My suggestion: rotate the air vent blades on your child's usual side to face upward, then use "setrear" to lock the temperature at 24°C. This prevents both chilling and button tampering.
