To turn on the cold air in an older Teana, you should first turn on the blower, then press the AC button, and adjust it to the blue zone. Taking the 2021 Teana as an example, it belongs to the mid-size car category with body dimensions of: length 4901mm, width 1850mm, height 1450mm, wheelbase 2825mm, fuel tank capacity 61.3l, and curb weight 1456kg. The 2021 Teana features a MacPherson strut front suspension and a trapezoidal control arm multi-link rear suspension. It is equipped with a 2.0L naturally aspirated engine, delivering a maximum horsepower of 156ps, maximum power of 115kw, maximum torque of 197nm, paired with a continuously variable transmission.

















Driving an old Teana with cool air is quite simple. After starting the engine, don't rush to drive off. Locate the air conditioning area on the center console, usually with an AC button—press it to activate the cooling compressor. Turn the temperature knob to the far left or the blue mark, indicating the lowest temperature. Adjust the fan speed knob higher to blow air for cooling; generally, setting it to level 2 or 3 is sufficient. Wait a few minutes for the cold air to come out, and avoid constantly adjusting it while driving to prevent distraction. In summer, open the windows slightly before use to release hot air and speed up cooling. If cool air doesn’t come, it might be due to insufficient refrigerant or a clogged filter, requiring . It's recommended to clean the air conditioning system once a year to prevent odors from affecting air quality.

I usually press the AC switch to activate the cooling as soon as I get in the car, and turn the temperature control directly to the lowest setting. The fan starts at maximum speed and returns to normal after cooling down. The recirculation button in older cars is also important—switch to recirculation mode when starting up for faster cooling. Avoid blasting cold air when the engine is still cold, as it’s less effective. It’s better to operate the AC after the engine has warmed up. Sometimes the fan noise is a bit loud, but it’s not a big deal. Regularly check the health, as a weak battery can affect the AC startup.

After starting the vehicle, locate the air conditioning panel and press the AC button. Turn the temperature knob to the blue zone. Adjust the fan speed. Open the windows slightly in advance to dissipate heat when it's hot. Avoid operating it while driving to prevent distraction. Occasionally, clean the filter if it's dirty.

Cool air is activated by the compressor. After starting the engine, press the AC button and turn the temperature control knob to the bottom to cool the air. The fan speed controls the airflow intensity. Temperature adjustment actually mixes hot and cold air. In summer, pay attention to the engine load to avoid overload, which affects fuel consumption. Check the air conditioning pressure to ensure it is normal.

After starting the car, lightly press the AC switch to activate the cooling mode. Turn the temperature knob to the cold zone to set a low temperature. Adjust the fan to an appropriate speed to avoid disturbing driving. Older cars cool down more slowly, so be patient. Before turning off the air conditioning when parking, switch to hot air to dry the pipelines, preventing mold growth—health comes first.
