To activate the cold air, press the AC switch and adjust the temperature by turning the left button towards the blue area. The middle position represents a moderate temperature. For warm air, adjust the temperature button towards the red area, and note that the AC switch does not need to be turned on for warm air. Below are some precautions for using car air conditioning: 1. Do not smoke in the car with the air conditioning on: Smoking in the confined space of the car can cause smoke to linger, irritating the eyes and respiratory system, which is harmful to health. If smoking is necessary, adjust the air conditioning ventilation control to the 'exhaust' position to expel the smoke from the car. 2. Avoid resting or sleeping for long periods in a stationary car with the air conditioning on: Due to the car's tight seal, ventilation is poor when the vehicle is stationary. Resting or sleeping with the air conditioning on in such conditions can lead to CO poisoning from engine exhaust leaking into the car, which can be fatal. 3. Minimize air conditioning use at low speeds: When encountering traffic jams, avoid running the engine at high RPMs to boost air conditioning efficiency, as this can negatively impact the lifespan of both the engine and the air conditioning compressor.

I've got plenty of experience with the AC in old Citroëns. First thing after getting in is to start the engine and let it run for about half a minute to warm up - that way the compressor can work properly. Look for the fan knob on the dashboard, turn it clockwise to adjust the fan speed: 1 for gentle breeze, 2 for medium, and 3 for powerful airflow. There's also an AC button nearby with a snowflake symbol or marked 'AC' - press it until the light comes on to activate the air conditioning. You'll hear the compressor humming when it kicks in, and cold air will start coming out. Don't forget to adjust the temperature knob - turn left for cold air, right for warm air to easily switch between cooling and heating. In summer, it's best to open the windows first to let hot air out before closing them and turning on the AC - this cools faster and saves fuel. If no cold air comes out, check if the button is properly pressed or if the filter needs cleaning. Regular maintenance keeps the system clean - old car AC systems are simple and practical, but don't run them too long to avoid straining the engine.

What are the reasons for the heavier steering wheel of the Fit?

The reasons for the heavier steering wheel of the Fit are: 1. Dirty power steering fluid: The power steering fluid is the force transmission medium. If the fluid is too dirty, it will cause poor circulation, making steering difficult; 2. Lack of power steering fluid or oil leakage: A lack of power steering fluid is equivalent to having no power assistance. Check the relevant system for any signs of oil leakage; 3. The engine power steering belt is too loose or too tight, or the belt is aged. The tightness can be adjusted, but an aged belt can only be replaced. Taking the Fit 2021 1.5L CVT Trend Edition as an example: It is a compact car launched by GAC Honda, with a length, width, and height of 4109mm, 1694mm, and 1537mm respectively, and a wheelbase of 2530mm. It is equipped with a 1.5L naturally aspirated engine, with a maximum power of 96kw, and is matched with a CVT continuously variable transmission.
