In-car AC refers to the air conditioning cooling switch. Pressing the AC button activates the air conditioning to adjust the temperature according to the set value, while turning it off only engages the air blower for ventilation without temperature regulation. More details about car air conditioning are as follows: 1. After turning on the air vent in a car, the air conditioning will blow air because the blower in the system starts operating. However, the cooling function hasn't been activated yet since the air conditioning compressor remains idle. 2. Only when the AC switch is turned on does the vehicle's computer receive the signal and subsequently instruct the air conditioning compressor to start working, initiating the cooling process of the car's air conditioning. To get cold air, you need to adjust the temperature selector to the blue zone and turn on the fan switch.

What is the mnemonic for gear shifting techniques for beginners?

Mnemonic for gear shifting techniques for beginners: 1. Start in first gear - After getting in the car, fasten the seatbelt, hold the steering wheel with the left hand, fully depress the clutch with the left foot, place the right hand on the gear lever to engage first gear, release the handbrake, then gradually release the clutch to start moving slowly. 2. Shift gears progressively - Start in first gear, immediately shift to second gear once the car moves, shift to third gear when speed exceeds 20 mph (no need for fourth gear), and directly jump to fifth gear when speed reaches 45 mph. 3. Keep eyes on the road - Beginners may instinctively look at the dashboard or gear lever while shifting, which is dangerous. Always maintain forward vision. When shifting, release the accelerator with the right foot, wait for stable speed, depress the clutch with the left foot, promptly change gears with the right hand while keeping the left hand firmly on the steering wheel.

Is the highway free on New Year's Day?

Highway tolls are not waived on New Year's Day. The toll-free periods on Chinese highways are limited to four national statutory holidays: Spring Festival, Qingming Festival, Labor Day, and National Day, as well as any consecutive holidays officially designated by the State Council. The free period starts at 0:00 on the first day of the holiday and ends at 24:00 on the last day. For ordinary roads, the toll-free status is determined by the time when the vehicle passes through the toll gate, while for highways, it is determined by the time when the vehicle exits the toll gate. The toll-free policy applies to passenger vehicles with seven seats or fewer, including motorcycles that are permitted to travel on ordinary toll roads. China implements a vehicle registration system, and motor vehicles must be registered with the traffic management department of the public security authorities before they can be driven on the road. For unregistered vehicles that need temporary road access, a temporary pass must be obtained.

What are the penalties for overloading?

Penalties for overloading: For passenger vehicles exceeding the rated passenger capacity on highways, a fine ranging from 200 to 500 yuan will be imposed; if the number of passengers exceeds 20% of the rated capacity or if goods are carried in violation of regulations, a fine ranging from 500 to 2,000 yuan will be imposed. For freight motor vehicles exceeding the approved load capacity, a fine ranging from 200 to 500 yuan will be imposed; if the load exceeds 30% of the approved capacity or if passengers are carried in violation of regulations, a fine ranging from 500 to 2,000 yuan will be imposed. Whether there is overloading is determined by whether the actual number of passengers exceeds the approved capacity, and the actual number of passengers does not distinguish between adults or children.

How to Get a Card on the Highway with a Temporary License Plate?

The method of obtaining a card on the highway with a temporary license plate is the same as that for a car with a regular license plate. The automatic card dispenser at the highway entrance detects the presence of a vehicle through magnetic field sensing and does not distinguish between temporary and regular license plates. However, the temporary license plate must be legitimate; otherwise, it is illegal. The steps to get a card are: 1. Slow down when entering the self-service card dispensing lane, move the car as close as possible to the edge of the card dispenser, and then press the button to get the card. The car should not be too far from the dispenser, or you won't be able to reach it. Opening the door to get out and take the card will waste time and may result in penalty points. 2. Whether at a manual card dispensing window or a self-service card dispenser, always shift to neutral and engage the handbrake. Many drivers fail to shift to neutral when taking the card, and if they accidentally press the accelerator, the car may lunge forward and hit the barrier, which is very dangerous.

How far can a 48v20ah battery actually go?

For a new 48v20ah electric vehicle battery, the actual range is about 50 to 60 kilometers. For an old battery, the range can be calculated based on driving habits. If you want to extend the range of a 48v20ah electric vehicle, you can add an additional battery pack. Currently, there are two types of electric vehicle batteries on the market: lead-acid batteries and lithium batteries. The lifespan of a lead-acid battery is defined by its capacity fading to 30% of its original capacity, typically around 300 full charge-discharge cycles, with a lifespan of about one and a half years. If the riding distance is short, it can last up to about 3 years. Lithium batteries have a strict charge cycle limit, around 1000 to 1200 cycles, with a lifespan of 3 to 5 years. Charging lithium batteries is the opposite of lead-acid batteries—they should be fully discharged before recharging. If the battery is not used for a long time, it should be fully charged every two months to protect the battery and extend its lifespan.
