How to Maintain a New Car?

Is it okay to idle the car overnight with the air conditioning on?

It is possible to idle the car overnight with the air conditioning on, but the main concern is fuel consumption. Here are some relevant points about idling with the air conditioning on: 1. Fuel consumption: There is no problem with idling and running the air conditioning, but the biggest issue is definitely fuel consumption, followed by waste. When driving with the air conditioning on, the power consumed by the air conditioning only accounts for a very small part of the engine's idle energy. However, when idling with the air conditioning on, the engine not only has to drive the air conditioning compressor but also needs to maintain the normal operation of the power steering and brake booster pumps. The latter two functions are completely unnecessary when parked, so keeping them running is a waste of power. 2. Harm to humans: Because the air inside the car cannot circulate, if carbon monoxide from the engine leaks into the car, it will gradually accumulate and increase in concentration, leading to poisoning.

Can car headlights be directly replaced with LED bulbs?

Car headlights can be directly replaced with LED bulbs. The benefits of switching to LED headlights are as follows: 1. Long lifespan: Lasting 50,000 to 100,000 hours, generally no need for replacement during the vehicle's lifespan. 2. Avoid fines: Due to the ultra-long lifespan of LEDs, it prevents fines caused by sudden light failure. 3. Circuit safety: The current in the lighting circuit is reduced from over ten amperes to less than one ampere, significantly lowering the risk of circuit fires. 4. Driving safety: Faster illumination provides longer braking time for following vehicles. Tests show that at 100 km/h, it can reduce the braking distance by 7.5 meters. 5. High brightness: Compared to traditional bulbs, LEDs offer purer color, higher brightness, and long-lasting color retention, providing better warning effects. 6. High durability: LEDs have far superior shock resistance and impact resistance compared to ordinary bulbs, along with advantages like compact size and strong environmental adaptability.

Does the 2021 Audi A6 not have a USB port?

Audi A6 does not have a USB port in the front row, only in the rear row. USB port current: The USB ports in the Audi A6 are designed for audio data transmission. The current of the car's USB ports can be either 5V/2.1A or 5V/0.5A. Many phones require an input current of 5V/1A. In this case, it can provide 1A current to the phone and 2A current to a tablet. If it's 5V/0.5A, the current will not meet the standard, resulting in longer charging times and causing the phone to overheat. Car charger: When converting the car's 12V voltage from the cigarette lighter to 5V, the car charger must go through multiple steps such as voltage stabilization, rectification, and overload protection. If low-quality components and materials are used, it can easily lead to short circuits or even spontaneous combustion.

What are the hidden features in the 2021 Excelle?

Here are the feature introductions for the 2021 Excelle: Weather alert function: It can provide alerts to the owner based on the day's weather, though it generally only appears during severe weather conditions; Natural voice recognition function: When there is a need, simply activate the voice function to immediately fulfill the requirement; Turn signal assist function: A light tap on the turn signal lever will make the turn signal flash three times, which is very practical for quick lane changes during overtaking; Low-temperature automatic warm-up function: When the temperature is below 10 degrees and the interior air circulation is not turned on, opening the sunroof will cause the Excelle to slightly heat the incoming air automatically. This function can be turned off by pressing the fan icon button. When the temperature is below 4 degrees and the interior air circulation is not turned on, the Excelle will automatically slightly heat the incoming air even without opening the sunroof, and this function can also be manually turned off.

What to Do When the Rearview Mirror Gets Blurred by Rainwater?

When the rearview mirror gets blurred by rainwater during rainy days, the following solutions can be applied: 1. Wax the rearview mirror. When water is on a waxed surface, the internal cohesion of the water becomes greater than its adhesion, preventing the formation of water droplets. However, wax is susceptible to external temperature influences, and improper application may impair visibility. 2. Install rain guards on the rearview mirror. Rain guards are suitable for use when the rain is not too heavy. Installing rain guards can also block water on the car windows, keeping both the rearview mirror and side windows clear. 3. Apply a water repellent to the rearview mirror. Applying a water repellent can maintain clear visibility by altering the surface tension of water on the glass, preventing water from sticking to the mirror's surface. 4. Use soap or dishwashing liquid to spray the rearview mirror. Cleaning agents contain surfactants, whose hydrophobic groups, due to their physical properties, push water outward, preventing the formation of water droplets.

Do You Need to Press the AC Button for Heating in New Energy Vehicles?

No need to press the AC button. The AC function button is mainly used to control the compressor, which provides cooling in summer. The car air conditioning AC does not have a heating function, so there is no need to press the AC button when using the car's heating system. Introduction to the air conditioning system of new energy vehicles: 1. The heating system of new energy vehicle air conditioning is different from that of traditional vehicle air conditioning. It consists of a compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower, among others. These components are connected by copper pipes (or aluminum pipes) and high-pressure rubber hoses to form a closed system. 2. In traditional vehicles, the air conditioning compressor is driven by the engine, while new energy vehicles use an electric compressor. 3. There are significant differences in the heating systems between the two. Traditional vehicles often use engine waste heat for heating, but new energy vehicles require an independent heat source, typically using a PTC heater (including PTC air heaters and PTC water heaters) or electric heating elements for heating.
