How to use the air conditioning in Roewe 750?

[LaNoah]

The usage method of the Roewe 750 air conditioning is as follows: 1. After starting the vehicle engine, click the OFF button on the central control panel to turn on the air conditioning. 2. After turning on the air conditioning, click the AC button on the air conditioning to enter the cooling mode, then adjust the appropriate temperature and air volume to start cooling. 3. If you want to turn on the heating mode, there is no need to press the AC button; simply increase the temperature and adjust the air volume to start heating. Additionally, when using the air conditioning in summer, be careful not to immediately activate the internal circulation after entering the car. Because the temperature inside the car is higher than the outside temperature, this would actually reduce the cooling effect. When you first enter the car, you should open the windows for ventilation and turn on the external circulation to expel the hot air. After the temperature inside the car has dropped, you can then switch to internal circulation.

I've been driving an old Roewe 750 for three years, and its air conditioning system is quite straightforward. The row of buttons in the middle of the dashboard is the AC control panel. The most frequently used is the large knob on the left—it adjusts the temperature: turn it to the right (red zone) for heating and to the left (blue zone) for cooling. The knob on the right controls the fan speed with five settings in total. In summer, remember to press the AC button first to activate the compressor; otherwise, you'll just get airflow without cooling. In winter, simply turn up the temperature for warm air without needing the AC. Here's a handy tip: When the windshield fogs up, press the button with the fan-shaped icon—it automatically maximizes airflow for quick defogging, much faster than manual adjustment. Don't randomly press the small round button under the glove compartment—it's the switch for the rear independent AC. Pressing it by mistake will turn off the rear vents.

Last week, I just taught my wife how to drive our family's Roewe 750, with a special focus on the air conditioning system. The easiest way is to press the AUTO button right after starting the car—the AC will automatically adjust the fan speed and temperature based on your settings. However, in auto mode, the fan noise might suddenly increase; don’t panic, as this is just the system quickly regulating the temperature. Manual mode offers more flexibility—the button with a wavy arrow switches between internal and external air circulation. Always use internal circulation in traffic jams to avoid inhaling exhaust fumes. If there’s an unpleasant smell from the AC, turn off the AC button and run just the fan for five minutes before shutting it off to reduce mold buildup. The rearview mirror heating button is located just below the AC controls—remember to turn it on during rain or snow, and don’t confuse it with the AC buttons.

A veteran with ten years of auto repair experience said that to make the Roewe 750's air conditioning last longer, attention to detail is crucial. Don't turn on the AC immediately after ignition; wait for the tachometer to stabilize before starting the compressor to reduce engine load. When using the heater, avoid adjusting the temperature knob until the water temperature rises, or you'll get cold air and risk catching a cold. The small display on the far right shows the set temperature, but the actual vent temperature is about three degrees lower, which is a normal design. The rear window defroster button automatically turns off after fifteen minutes to prevent battery drain. If the air conditioning smells bad, it's likely due to a dirty filter, which can be replaced for just fifty yuan at a repair shop.

Long-distance driving tips: Don't keep the Roewe 750's AC at maximum fan speed throughout the journey. In the city, level 3 fan speed provides sufficient cooling, while level 2 on highways is more fuel-efficient due to lower power consumption by the blower. If there are independent rear air vents, don't completely close the rotary wheel behind the armrest box, or the front seats will freeze while the rear remains stuffy. After exposure to intense sunlight, open the windows for a minute before turning on the AC for faster cooling. A hidden feature—holding the recirculation button for three seconds automatically closes all windows, which is especially useful on rainy days. It's recommended to replace the AC filter every two years; purchasing a 30-yuan Mann filter online is half the price of getting it at a 4S shop.

In winter, turn on the heater without pressing the AC button. Simply adjust the temperature knob above 24°C to use engine heat for better fuel efficiency. In summer, close the windows before turning on the AC for cooling, and adjust the vents upward for faster cooling. When defogging the windshield, the AC automatically switches to external circulation—avoid forcing the internal circulation button to prevent fogging. If no one is sitting in the back, close the vents on the B-pillar to improve front cooling efficiency. Note that the AC lines should be checked every three years, as older cars are prone to refrigerant leaks. If the AC is on but the vents aren’t blowing cold air, it might be low on refrigerant—just visit a repair shop to top it up with two cans.
