How to Turn on the Air Conditioning Cooling in an Audi A4?

Audi A4 air conditioning cooling activation method is as follows: 1. Turn on the car's ignition switch. 2. Turn on the air conditioning switch. 3. Press the A/C button to activate the cooling mode. Precautions for turning on the car air conditioning are as follows: 1. Select the appropriate fan speed. During normal car operation, to prevent excessive frosting of the evaporator, which could affect the air conditioning system's operation, the air conditioning's fan speed and temperature control should not be set at the lowest for extended periods. 2. Regularly start the air conditioning in winter. Prolonged disuse can cause the rubber seals to age, and the lubricating oil on internal components to dry out. Regular activation allows components to be lubricated and maintained in good condition. 3. Avoid using the air conditioning for too long in a single session. If the interior temperature has reached a comfortable level, turn off the air conditioning or switch it on again after a while. 4. Ventilate to cool down before driving in summer, then switch to recirculation mode. Upon entering the car, first open the windows for ventilation and turn on the external circulation to expel hot air. After the cabin temperature drops, switch to internal circulation.

Can LED headlights be installed without lenses?

LEDs and lenses need to be installed together. Without a lens, the light scattering will be severe, which actually reduces the visibility of the LED. Therefore, when installing LED lights, a lens must also be installed. LED bulbs have good light concentration, and the light-shielding plate inside the lens is used to switch between high and low beams. The light pattern produced by a bi-xenon lens naturally forms a low beam with a clear cutoff line. However, without a lens, the light-shielding plate is absent, preventing the LED bulb's light concentration from being fully utilized, resulting in light scattering. Automotive lenses are divided into two types: 1. Single-beam lens: Only has a low beam, using halogen or xenon bulbs. 2. Bi-xenon lens: Achieves switching between high and low beams through an internal light-shielding plate. When the light-shielding plate is closed, it is the low beam; when opened, it is the high beam. If the bulb inside the lens remains unchanged, there will be no variation.
